# Adding new devices to a device tree
|
||||||
|
|
||||||
|
## Introduction
|
||||||
|
|
||||||
|
ACPI exposes a platform-independent interface for operating systems to perform
|
||||||
|
power management and other platform-level functions. Some operating systems
|
||||||
|
also use ACPI to enumerate devices that are not immediately discoverable, such
|
||||||
|
as those behind I2C or SPI buses (in contrast to PCI). This document discusses
|
||||||
|
the way that coreboot uses the concept of a "device tree" to generate ACPI
|
||||||
|
tables for usage by the operating system.
|
||||||
|
|
||||||
|
## Devicetree and overridetree (if applicable)
|
||||||
|
|
||||||
|
For mainboards that are organized around a "reference board" or "baseboard"
|
||||||
|
model (see ``src/mainboard/google/octopus`` or ``hatch`` for examples), there is
|
||||||
|
typically a devicetree.cb file that all boards share, and any differences for a
|
||||||
|
specific board ("variant") are captured in the overridetree.cb file. Any
|
||||||
|
settings changed in the overridetree take precedence over those in the main
|
||||||
|
devicetree. Note, not all mainboards will have the devicetree/overridetree
|
||||||
|
distinction, and may only have a devicetree.cb file. Or you can always just
|
||||||
|
write the ASL (ACPI Source Language) code yourself.
|
||||||
|
|
||||||
|
### Naming and referencing devices
|
||||||
|
|
||||||
|
When declaring a device, it can optionally be given an alias that can be
|
||||||
|
referred to elsewhere. This is particularly useful to declare a device in one
|
||||||
|
device tree while allowing its configuration to be more easily changed in an
|
||||||
|
overlay. For instance, the AMD Picasso SoC definition
|
||||||
|
(`soc/amd/picasso/chipset.cb`) declares an IOMMU on a PCI bus that is disabled
|
||||||
|
by default:
|
||||||
|
|
||||||
|
```
|
||||||
|
chip soc/amd/picasso
|
||||||
|
device domain 0 on
|
||||||
|
...
|
||||||
|
device pci 00.2 alias iommu off end
|
||||||
|
...
|
||||||
|
end
|
||||||
|
end
|
||||||
|
```
|
||||||
|
|
||||||
|
A device based on this SoC can override the configuration for the IOMMU without
|
||||||
|
duplicating addresses, as in
|
||||||
|
`mainboard/google/zork/variants/baseboard/devicetree_trembyle.cb`:
|
||||||
|
|
||||||
|
```
|
||||||
|
chip soc/amd/picasso
|
||||||
|
device domain 0
|
||||||
|
...
|
||||||
|
device ref iommu on end
|
||||||
|
...
|
||||||
|
end
|
||||||
|
end
|
||||||
|
```
|
||||||
|
|
||||||
|
In this example the override simply enables the IOMMU, but it could also
|
||||||
|
set additional properties (or even add child devices) inside the IOMMU `device`
|
||||||
|
block.
|
||||||
|
|
||||||
|
---
|
||||||
|
|
||||||
|
It is important to note that devices that use `device ref` syntax to override
|
||||||
|
previous definitions of a device by alias must be placed at **exactly the same
|
||||||
|
location in the device tree** as the original declaration. If not, this will
|
||||||
|
actually create another device rather than overriding the properties of the
|
||||||
|
existing one. For instance, if the above snippet from `devicetree_trembyle.cb`
|
||||||
|
were written as follows:
|
||||||
|
|
||||||
|
```
|
||||||
|
chip soc/amd/picasso
|
||||||
|
# NOTE: not inside domain 0!
|
||||||
|
device ref iommu on end
|
||||||
|
end
|
||||||
|
```
|
||||||
|
|
||||||
|
Then this would leave the SoC's IOMMU disabled, and instead create a new device
|
||||||
|
with no properties as a direct child of the SoC.
|
||||||
|
|
||||||
|
## Device drivers
|
||||||
|
|
||||||
|
Let's take a look at an example entry from
|
||||||
|
``src/mainboard/google/hatch/variants/hatch/overridetree.cb``:
|
||||||
|
|
||||||
|
```
|
||||||
|
device pci 15.0 on
|
||||||
|
chip drivers/i2c/generic
|
||||||
|
register "hid" = ""ELAN0000""
|
||||||
|
register "desc" = ""ELAN Touchpad""
|
||||||
|
register "irq" = "ACPI_IRQ_WAKE_LEVEL_LOW(GPP_A21_IRQ)"
|
||||||
|
register "wake" = "GPE0_DW0_21"
|
||||||
|
device i2c 15 on end
|
||||||
|
end
|
||||||
|
end # I2C #0
|
||||||
|
```
|
||||||
|
|
||||||
|
When this entry is processed during ramstage, it will create a device in the
|
||||||
|
ACPI SSDT table (all devices in devicetrees end up in the SSDT table). The ACPI
|
||||||
|
generation routines in coreboot actually generate the raw bytecode that
|
||||||
|
represents the device's structure, but looking at ASL code is easier to
|
||||||
|
understand; see below for what the disassembled bytecode looks like:
|
||||||
|
|
||||||
|
```
|
||||||
|
Scope (\_SB.PCI0.I2C0)
|
||||||
|
{
|
||||||
|
Device (D015)
|
||||||
|
{
|
||||||
|
Name (_HID, "ELAN0000") // _HID: Hardware ID
|
||||||
|
Name (_UID, Zero) // _UID: Unique ID
|
||||||
|
Name (_DDN, "ELAN Touchpad") // _DDN: DOS Device Name
|
||||||
|
Method (_STA, 0, NotSerialized) // _STA: Status
|
||||||
|
{
|
||||||
|
Return (0x0F)
|
||||||
|
}
|
||||||
|
Name (_CRS, ResourceTemplate () // _CRS: Current Resource Settings
|
||||||
|
{
|
||||||
|
I2cSerialBusV2 (0x0015, ControllerInitiated, 400000,
|
||||||
|
AddressingMode7Bit, "\\_SB.PCI0.I2C0",
|
||||||
|
0x00, ResourceConsumer, , Exclusive, )
|
||||||
|
Interrupt (ResourceConsumer, Level, ActiveLow, ExclusiveAndWake, ,, )
|
||||||
|
{
|
||||||
|
0x0000002D,
|
||||||
|
}
|
||||||
|
})
|
||||||
|
Name (_S0W, ACPI_DEVICE_SLEEP_D3_HOT) // _S0W: S0 Device Wake State
|
||||||
|
Name (_PRW, Package (0x02) // _PRW: Power Resources for Wake
|
||||||
|
{
|
||||||
|
0x15, // GPE #21
|
||||||
|
0x03 // Sleep state S3
|
||||||
|
})
|
||||||
|
}
|
||||||
|
}
|
||||||
|
```
|
||||||
|
|
||||||
|
You can see it generates _HID, _UID, _DDN, _STA, _CRS, _S0W, and _PRW
|
||||||
|
names/methods in the Device's scope.
|
||||||
|
|
||||||
|
## Utilizing a device driver
|
||||||
|
|
||||||
|
The device driver must be enabled for your build. There will be a CONFIG option
|
||||||
|
in the Kconfig file in the directory that the driver is in (e.g.,
|
||||||
|
``src/drivers/i2c/generic`` contains a Kconfig file; the option here is named
|
||||||
|
CONFIG_DRIVERS_I2C_GENERIC). The config option will need to be added to your
|
||||||
|
mainboard's Kconfig file (e.g., ``src/mainboard/google/hatch/Kconfig``) in order
|
||||||
|
to be compiled into your build.
|
||||||
|
|
||||||
|
## Diving into the above example:
|
||||||
|
|
||||||
|
Let's take a look at how the devicetree language corresponds to the generated
|
||||||
|
ASL.
|
||||||
|
|
||||||
|
First, note this:
|
||||||
|
|
||||||
|
```
|
||||||
|
chip drivers/i2c/generic
|
||||||
|
```
|
||||||
|
|
||||||
|
This means that the device driver we're using has a corresponding structure,
|
||||||
|
located at ``src/drivers/i2c/generic/chip.h``, named **struct
|
||||||
|
drivers_i2c_generic_config** and it contains many properties you can specify to
|
||||||
|
be included in the ACPI table.
|
||||||
|
|
||||||
|
### hid
|
||||||
|
|
||||||
|
```
|
||||||
|
register "hid" = ""ELAN0000""
|
||||||
|
```
|
||||||
|
|
||||||
|
This corresponds to **const char *hid** in the struct. In the ACPI ASL, it
|
||||||
|
translates to:
|
||||||
|
|
||||||
|
```
|
||||||
|
Name (_HID, "ELAN0000") // _HID: Hardware ID
|
||||||
|
```
|
||||||
|
|
||||||
|
under the device. **This property is used to match the device to its driver
|
||||||
|
during enumeration in the OS.**
|
||||||
|
|
||||||
|
### desc
|
||||||
|
|
||||||
|
```
|
||||||
|
register "desc" = ""ELAN Touchpad""
|
||||||
|
```
|
||||||
|
|
||||||
|
corresponds to **const char *desc** and in ASL:
|
||||||
|
|
||||||
|
```
|
||||||
|
Name (_DDN, "ELAN Touchpad") // _DDN: DOS Device Name
|
||||||
|
```
|
||||||
|
|
||||||
|
### irq
|
||||||
|
|
||||||
|
It also adds the interrupt,
|
||||||
|
|
||||||
|
```
|
||||||
|
Interrupt (ResourceConsumer, Level, ActiveLow, ExclusiveAndWake, ,, )
|
||||||
|
{
|
||||||
|
0x0000002D,
|
||||||
|
}
|
||||||
|
```
|
||||||
|
|
||||||
|
which comes from:
|
||||||
|
|
||||||
|
```
|
||||||
|
register "irq" = "ACPI_IRQ_WAKE_LEVEL_LOW(GPP_A21_IRQ)"
|
||||||
|
```
|
||||||
|
|
||||||
|
The GPIO pin IRQ settings control the "Level", "ActiveLow", and
|
||||||
|
"ExclusiveAndWake" settings seen above (level means it is a level-triggered
|
||||||
|
interrupt as opposed to edge-triggered; active low means the interrupt is
|
||||||
|
triggered when the signal is low).
|
||||||
|
|
||||||
|
Note that the ACPI_IRQ_WAKE_LEVEL_LOW macro informs the platform that the GPIO
|
||||||
|
will be routed through SCI (ACPI's System Control Interrupt) for use as a wake
|
||||||
|
source. Also note that the IRQ names are SoC-specific, and you will need to
|
||||||
|
find the names in your SoC's header file. The ACPI_* macros are defined in
|
||||||
|
``src/arch/x86/include/acpi/acpi_device.h``.
|
||||||
|
|
||||||
|
Using a GPIO as an IRQ requires that it is configured in coreboot correctly.
|
||||||
|
This is often done in a mainboard-specific file named ``gpio.c``.
|
||||||
|
|
||||||
|
### wake
|
||||||
|
|
||||||
|
The last register is:
|
||||||
|
|
||||||
|
```
|
||||||
|
register "wake" = "GPE0_DW0_21"
|
||||||
|
```
|
||||||
|
|
||||||
|
which indicates that the method of waking the system using the touchpad will be
|
||||||
|
through a GPE, #21 associated with DW0, which is set up in devicetree.cb from
|
||||||
|
this example. The "21" indicates GPP_X21, where GPP_X is mapped onto DW0
|
||||||
|
elsewhere in the devicetree.
|
||||||
|
|
||||||
|
The last bit of the definition of that device includes:
|
||||||
|
|
||||||
|
```
|
||||||
|
device i2c 15 on end
|
||||||
|
```
|
||||||
|
|
||||||
|
which means it's an I2C device, with 7-bit address 0x15, and the device is "on",
|
||||||
|
meaning it will be exposed in the ACPI table. The PCI device that the
|
||||||
|
controller is located in determines which I2C bus the device is expected to be
|
||||||
|
found on. In this example, this is I2C bus 0. This also determines the ACPI
|
||||||
|
"Scope" that the device names and methods will live under, in this case
|
||||||
|
"\_SB.PCI0.I2C0".
|
||||||
|
|
||||||
|
## Other auto-generated names
|
||||||
|
|
||||||
|
(see [ACPI specification
|
||||||
|
6.3](https://uefi.org/sites/default/files/resources/ACPI_6_3_final_Jan30.pdf)
|
||||||
|
for more details on ACPI methods)
|
||||||
|
|
||||||
|
### _S0W (S0 Device Wake State)
|
||||||
|
_S0W indicates the deepest S0 sleep state this device can wake itself from,
|
||||||
|
which in this case is ACPI_DEVICE_SLEEP_D3_HOT, representing _D3hot_.
|
||||||
|
|
||||||
|
### _PRW (Power Resources for Wake)
|
||||||
|
_PRW indicates the power resources and events required for wake. There are no
|
||||||
|
dependent power resources, but the GPE (GPE0_DW0_21) is mentioned here (0x15),
|
||||||
|
as well as the deepest sleep state supporting waking the system (3), which is
|
||||||
|
S3.
|
||||||
|
|
||||||
|
### _STA (Status)
|
||||||
|
The _STA method is generated automatically, and its values, 0xF, indicates the
|
||||||
|
following:
|
||||||
|
|
||||||
|
Bit [0] – Set if the device is present.
|
||||||
|
Bit [1] – Set if the device is enabled and decoding its resources.
|
||||||
|
Bit [2] – Set if the device should be shown in the UI.
|
||||||
|
Bit [3] – Set if the device is functioning properly (cleared if device failed its diagnostics).
|
||||||
|
|
||||||
|
### _CRS (Current resource settings)
|
||||||
|
The _CRS method is generated automatically, as the driver knows it is an I2C
|
||||||
|
controller, and so specifies how to configure the controller for proper
|
||||||
|
operation with the touchpad.
|
||||||
|
|
||||||
|
```
|
||||||
|
Name (_CRS, ResourceTemplate () // _CRS: Current Resource Settings
|
||||||
|
{
|
||||||
|
I2cSerialBusV2 (0x0015, ControllerInitiated, 400000,
|
||||||
|
AddressingMode7Bit, "\\_SB.PCI0.I2C0",
|
||||||
|
0x00, ResourceConsumer, , Exclusive, )
|
||||||
|
```
|
||||||
|
|
||||||
|
## Notes
|
||||||
|
|
||||||
|
- **All fields that are left unspecified in the devicetree are initialized to
|
||||||
|
zero.**
|
||||||
|
- **All devices in devicetrees end up in the SSDT table, and are generated in
|
||||||
|

# Testing ACPI changes under Windows
|
|
||||||
|
|
||||||
When testing ACPI changes in coreboot against Windows 8 or newer, beware that
|
|
||||||
during a normal boot after a clean shutdown, Windows will use the fast startup
|
|
||||||
mechanism which results in it not evaluating the changed ACPI code but instead
|
|
||||||
using some cached version which won't include the changes that were supposed to
|
|
||||||
be tested. In order for Windows to actually use the new ACPI tables, either
|
|
||||||
disable the fast startup or just tell Windows to do a reboot which will make it
|
|
||||||
read and use the ACPI tables in memory instead of an outdated cached version.

# Accounts on coreboot.org
|
||||||
|
|
||||||
|
There are a number of places where you can benefit from creaating an account
|
||||||
|
in our community. Since there is no single sign-on system in place (at this
|
||||||
|
time), they come with their own setup routines.
|
||||||
|
|
||||||
|
## Gerrit code review
|
||||||
|
We exchange and review patches to the code using our [Gerrit code review
|
||||||
|
system](https://review.coreboot.org).
|
||||||
|
|
||||||
|
It allows logging in with a Google or GitHub account using OAuth2 as well
|
||||||
|
as with any OpenID provider that you may already use.
|
||||||
|
|
||||||
|
On the [settings screen](https://review.coreboot.org/settings) you can register
|
||||||
|
all your email addresses you intend to use in the context of coreboot
|
||||||
|
development so that commits with your email address in them are associated with
|
||||||
|
you properly.
|
||||||
|
|
||||||
|
### https push access
|
||||||
|
When using the https URLs to git repositories, you can push with the "HTTP
|
||||||
|
Credentials" you can have Gerrit generate for you on that page. By default,
|
||||||
|
git uses `$HOME/.netrc` for http authentication data, so add a line there
|
||||||
|
stating:
|
||||||
|
|
||||||
|
machine review.coreboot.org login $your-user-name password $your-password
|
||||||
|
|
||||||
|
### Gerrit user avatar
|
||||||
|
To setup an avatar to show in Gerrit, clone the avatars repository at
|
||||||
|
https://review.coreboot.org/gerrit-avatars.git and add a file named
|
||||||
|
$your-user-ID.jpg (the user ID is a number shown on the [settings screen](https://review.coreboot.org/settings)).
|
||||||
|
The image must be provided in JPEG format, must be square and have at most 50000
|
||||||
|
bytes.
|
||||||
|
|
||||||
|
After you push for review, the system will automatically verify your change
|
||||||
|
and, if adhering to these constraints, approve it. You can then immediately
|
||||||
|
submit it.
|
||||||
|
|
||||||
|
## Issue tracker
|
||||||
|
We have an [issue tracker](https://ticket.coreboot.org) that is used for
|
||||||
|
coreboot and related code, such as libpayload, as well as for the project's
|
||||||
|
infrastructure.
|
||||||
|
|
||||||
|
It can be helpful to refer to issues we track there in commit messages:

Data structures
|
||||||
|
---------------
|
||||||
|
|
||||||
|
Data structures that have visibility outside the single-threaded
|
||||||
|
environment they are created and destroyed in should always have
|
||||||
|
reference counts. In the kernel, garbage collection doesn't exist (and
|
||||||
|
outside the kernel garbage collection is slow and inefficient), which
|
||||||
|
means that you absolutely _have_ to reference count all your uses.
|
||||||
|
|
||||||
|
Reference counting means that you can avoid locking, and allows multiple
|
||||||
|
users to have access to the data structure in parallel - and not having
|
||||||
|
to worry about the structure suddenly going away from under them just
|
||||||
|
because they slept or did something else for a while.
|
||||||
|
|
||||||
|
Note that locking is _not_ a replacement for reference counting.
|
||||||
|
Locking is used to keep data structures coherent, while reference
|
||||||
|
counting is a memory management technique. Usually both are needed, and
|
||||||
|
they are not to be confused with each other.
|
||||||
|
|
||||||
|
Many data structures can indeed have two levels of reference counting,
|
||||||
|
when there are users of different "classes". The subclass count counts
|
||||||
|
the number of subclass users, and decrements the global count just once
|
||||||
|
when the subclass count goes to zero.
|
||||||
|
|
||||||
|
Examples of this kind of "multi-level-reference-counting" can be found
|
||||||
|
in memory management ("struct mm_struct": mm_users and mm_count),
|
||||||
|
and in filesystem code ("struct super_block": s_count and
|
||||||
|
s_active).
|
||||||
|
|
||||||
|
Remember: if another thread can find your data structure, and you don't
|
||||||
|
have a reference count on it, you almost certainly have a bug.

There are a number of driver model diagnostic macros in
|
||||||
|
<linux/device.h> which you should use to make sure messages are
|
||||||
|
matched to the right device and driver, and are tagged with the right
|
||||||
|
level: dev_err(), dev_warn(), dev_info(), and so forth. For messages
|
||||||
|
that aren't associated with a particular device, <linux/printk.h>
|
||||||
|
defines pr_debug() and pr_info().
|
||||||
|
|
||||||
|
Coming up with good debugging messages can be quite a challenge; and
|
||||||
|
once you have them, they can be a huge help for remote troubleshooting.
|
||||||
|
Such messages should be compiled out when the DEBUG symbol is not
|
||||||
|
defined (that is, by default they are not included). When you use
|
||||||
|
dev_dbg() or pr_debug(), that's automatic. Many subsystems have
|
||||||
|
Kconfig options to turn on -DDEBUG. A related convention uses
|
||||||
|
VERBOSE_DEBUG to add dev_vdbg() messages to the ones already enabled
|
||||||
|
by DEBUG.

Error handling, assertions and die()
|
|
||||||
-----------------------------
|
|
||||||
|
|
||||||
As firmware, coreboot has no means to let the user interactively fix things when
|
|
||||||
something goes wrong. We either succeed to boot or the device becomes a brick
|
|
||||||
that must be recovered through complicated external means (e.g. a flash
|
|
||||||
programmer). Therefore, coreboot code should strive to continue booting
|
|
||||||
wherever possible.
|
|
||||||
|
|
||||||
In most cases, errors should be handled by logging a message of at least
|
|
||||||
`BIOS_ERR` level, returning out of the function stack for the failed feature,
|
|
||||||
and then continuing execution. For example, if a function reading the EDID of an
|
|
||||||
eDP display panel encounters an I2C error, it should print a "cannot read EDID"
|
|
||||||
message and return an error code. The calling display initialization function
|
|
||||||
knows that without the EDID there is no way to initialize the display correctly,
|
|
||||||
so it will also immediately return with an error code without running its
|
|
||||||
remaining code that would initialize the SoC's display controller. Execution
|
|
||||||
returns further up the function stack to the mainboard initialization code
|
|
||||||
which continues booting despite the failed display initialization, since
|
|
||||||
display functionality is non-essential to the system. (Code is encouraged but
|
|
||||||
not required to use `enum cb_err` error codes to return these errors.)
|
|
||||||
|
|
||||||
coreboot also has the `die()` function that completely halts execution. `die()`
|
|
||||||
should only be used as a last resort, since it results in the worst user
|
|
||||||
experience (bricked system). It is generally preferrable to continue executing
|
|
||||||
even after a problem was encountered that might be fatal (e.g. SPI clock
|
|
||||||
couldn't be configured correctly), because a slight chance of successfully
|
|
||||||
booting is still better than not booting at all. The only cases where `die()`
|
|
||||||
should be used are:
|
|
||||||
|
|
||||||
1. There is no (simple) way to continue executing. For example, when loading the
|
|
||||||
next stage from SPI flash fails, we don't have any more code to execute. When
|
|
||||||
memory initialization fails, we have no space to load the ramstage into.
|
|
||||||
|
|
||||||
2. Continuing execution would pose a security risk. All security features in
|
|
||||||
coreboot are optional, but when they are configured in the user must be able
|
|
||||||
to rely on them. For example, if CBFS verification is enabled and the file
|
|
||||||
hash when loading the romstage doesn't match what it should be, it is better
|
|
||||||
to stop execution than to jump to potentially malicious code.
|
|
||||||
|
|
||||||
In addition to normal error logging with `printk()`, coreboot also offers the
|
|
||||||
`assert()` macro. `assert()` should be used judiciously to confirm that
|
|
||||||
conditions are true which the programmer _knows_ to be true, in order to catch
|
|
||||||
programming errors and incorrect assumptions. It is therefore different from a
|
|
||||||
normal `if ()`-check that is used to actually test for things which may turn
|
|
||||||
out to be true or false based on external conditions. For example, anything
|
|
||||||
that involves communicating with hardware, such as whether an attempt to read
|
|
||||||
from SPI flash succeeded, should _not_ use `assert()` and should instead just
|
|
||||||
be checked with a normal `if ()` and subsequent manual error handling. Hardware
|
|
||||||
can always fail for various reasons and the programmer can never 100% assume in
|
|
||||||
advance that it will work as expected. On the other hand, if a function takes a
|
|
||||||
pointer parameter `ctx` and the contract for that function (as documented in a
|
|
||||||
comment above its declaration) specifies that this parameter should point to a
|
|
||||||
valid context structure, then adding an `assert(ctx)` line to that function may
|
|
||||||
be a good idea. The programmer knows that this function should never be called
|
|
||||||
with a NULL pointer (because that's how it is specified), and if it was actually
|
|
||||||
called with a NULL pointer that would indicate a programming error on account of
|
|
||||||
the caller.
|
|
||||||
|
|
||||||
`assert()` can be configured to either just print an error message and continue
|
|
||||||
execution (default), or call `die()` (when `CONFIG_FATAL_ASSERTS` is set).
|
|
||||||
Developers are encouraged to always test their code with this option enabled to
|
|
||||||
make assertion errors (and therefore bugs) more easy to notice. Since assertions
|
|
||||||
thus do not always stop execution, they should never be relied upon to be the
|
|
||||||
sole guard against conditions that really _need_ to stop execution (e.g.
|
|
||||||
security guarantees should never be enforced only by `assert()`).

|
||||||
GCC extensions
|
|
||||||
--------------
|
|
||||||
|
|
||||||
GCC is the only officially-supported compiler for coreboot, and a
|
|
||||||
variety of its C language extensions are heavily used throughout the
|
|
||||||
code base. There have been occasional attempts to add clang as a second
|
|
||||||
compiler option, which is generally compatible to the same language
|
|
||||||
extensions that have been long-established by GCC.
|
|
||||||
|
|
||||||
Some GCC extensions (e.g. inline assembly) are basically required for
|
|
||||||
proper firmware development. Others enable more safe or flexible
|
|
||||||
coding patterns than can be expressed with standard C (e.g. statement
|
|
||||||
expressions and `typeof()` to avoid double evaluation in macros like
|
|
||||||
`MAX()`). Yet others just add some simple convenience and reduce
|
|
||||||
boilerplate (e.g. `void *` arithmetic).
|
|
||||||
|
|
||||||
Since some GCC extensions are necessary either way, there is no gain
|
|
||||||
from avoiding other GCC extensions elsewhere. The use of all official
|
|
||||||
GCC extensions is expressly allowed within coreboot. In cases where an
|
|
||||||
extension can be replaced by a 100% equivalent C standard feature with
|
|
||||||
no extra boilerplate or loss of readability, the C standard feature
|
|
||||||
should be preferred (this usually only happens when GCC retains an
|
|
||||||
older pre-standardization extension for backwards compatibility, e.g.
|
|
||||||
the old pre-C99 syntax for designated initializers). But if there is
|
|
||||||
any advantage offered by the GCC extension (e.g. using GCC zero-length
|
|
||||||
arrays instead of C99 variable-length arrays because they don't inhibit
|
|
||||||
`sizeof()`), there is no reason to deprive ourselves of that, and "this
|
|
||||||
is not C standard compliant" should not be a reason to argue against
|
|
||||||
its use in reviews.
|
|
||||||
|
|
||||||
This rule only applies to explicit GCC extensions listed in the
|
|
||||||
"Extensions to the C Language Family" section of the GCC manual. Code
|
|
||||||
should never rely on incidental GCC translation behavior that is not
|
|
||||||
explicitly documented as a feature and could change at any moment.
|
|
||||||
|
|
||||||
Refactoring
|
|
||||||
-----------
|
|
||||||
Because refactoring existing code can add bugs to tested code, any
|
|
||||||
refactors should be done only with serious consideration. Refactoring
|
|
||||||
for style differences should only be done if the existing style
|
|
||||||
conflicts with a documented coreboot guideline. If you believe that the
|
|
||||||
style should be modified, the pros and cons can be discussed on the
|
|
||||||
mailing list and in the coreboot leadership meeting.
|
|
||||||
|
|
||||||
Similarly, the original author should be respected. Changing working
|
|
||||||
code simply because of a stylistic disagreement is *prohibited*. This is
|
|
||||||
not saying that refactors that are objectively better (simpler, faster,
|
|
||||||
easier to understand) are not allowed, but there has to be a definite
|
|
||||||
improvement, not simply stylistic changes.
|
|
||||||
|
|
||||||
Basically, when refactoring code, there should be a clear benefit to
|
|
||||||
the project and codebase. The reviewers and submitters get to make the
|
|
||||||
call on how to interpret this.
|
|
||||||
|
|
||||||
When refactoring, adding unit tests to verify that the post-change
|
|
||||||
functionality matches or improves upon pre-change functionality is
|
|
||||||
encouraged.

## Organization admins
|
|
||||||
|
|
||||||
The *organization admins* are managing the GSoC program for the coreboot
|
|
||||||
organization.
|
|
||||||
|
|
||||||
The organization admins are:
|
|
||||||
|
|
||||||
* Felix Singer (primary)
|
|
||||||
* Martin Roth
|
|
||||||
* David Hendricks
|
|
||||||
|
|
||||||
|
|
||||||
## Contacts
|
|
||||||
|
|
||||||
If you are interested in participating in GSoC as a contributor or mentor,
|
|
||||||
please have a look at our [community forums] and reach out to us. Working closely
|
|
||||||
with the community is highly encouraged, as we've seen that our most successful
|
|
||||||
contributors are generally very involved.
|
|
||||||
|
|
||||||
|
|
||||||
## Why work on coreboot for GSoC?
|
|
||||||
|
|
||||||
* coreboot offers you the opportunity to work with various architectures
|
|
||||||
right on the iron. coreboot supports both current and older silicon for a
|
|
||||||
wide variety of chips and technologies.
|
|
||||||
|
|
||||||
* coreboot has a worldwide developer and user base.
|
|
||||||
|
|
||||||
* We are a very passionate team, so you will interact directly with the
|
|
||||||
project initiators and project leaders.
|
|
||||||
|
|
||||||
* We have a large, helpful community. coreboot has some extremely talented
|
|
||||||
and helpful experts in firmware involved in the project. They are ready to
|
|
||||||
assist and mentor contributors participating in GSoC.
|
|
||||||
|
|
||||||
* One of the last areas where open source software is not common is firmware.
|
|
||||||
Running proprietary firmware can have severe effects on user's freedom and
|
|
||||||
security. coreboot has a mission to change that by providing a common
|
|
||||||
framework for initial hardware initialization and you can help us succeed.

## Contributor requirements & commitments
|
|
||||||
|
|
||||||
Google Summer of Code is a significant time commitment for you. Medium-sized
|
|
||||||
projects are estimated to take 175 hours, while large-sized projects are
|
|
||||||
estimated to take 350 hours. Depending on the project size, this means we
|
|
||||||
expect you to work roughly half-time or full-time on your project during the
|
|
||||||
three months of coding. We expect to be able to see this level of effort in the
|
|
||||||
results.
|
|
||||||
|
|
||||||
The standard program duration is 12 weeks and in consultation with the mentor
|
|
||||||
it can be extended up to 22 weeks. Please keep in mind that the actual number
|
|
||||||
of hours you spend on the project highly depends on your skills and previous
|
|
||||||
experience.
|
|
||||||
|
|
||||||
Make sure that your schedule (exams, courses, day job) gives you a sufficient
|
|
||||||
amount of spare time. If this is not the case, then you should not apply.
|
|
||||||
|
|
||||||
|
|
||||||
### Before applying
|
|
||||||
|
|
||||||
* Join the [mailing list] and our other [community forums]. Introduce yourself
|
|
||||||
and mention that you are a prospective GSoC contributor. Ask questions and
|
|
||||||
discuss the project that you are considering. Community involvement is a
|
|
||||||
key component of coreboot development.
|
|
||||||
|
|
||||||
* You accept our [Code of Conduct] and [Language style].
|
|
||||||
|
|
||||||
* Demonstrate that you can work with the coreboot codebase.
|
|
||||||
|
|
||||||
* Look over some of the development processes guidelines: [Getting started],
|
|
||||||
[Tutorial], [Flashing firmware tutorial] and [Coding style].
|
|
||||||
|
|
||||||
* Download, build and boot coreboot in QEMU or on real hardware. Please email
|
|
||||||
your serial output results to the [mailing list].
|
|
||||||
|
|
||||||
* Look through some patches on Gerrit to get an understanding of the review
|
|
||||||
process and common issues.
|
|
||||||
|
|
||||||
* Get signed up for Gerrit and push at least one patch to Gerrit for review.
|
|
||||||
Check the [small project list][Project ideas] or ask for simple tasks on
|
|
||||||
the [mailing list] or on our other [community forums] if you need ideas.
|
|
||||||
|
|
||||||
|
|
||||||
### During the program
|
|
||||||
|
|
||||||
* To pass and to be paid by Google requires that you meet certain milestones.
|
|
||||||
|
|
||||||
* First, you must be in good standing with the community before the official
|
|
||||||
start of the program. We expect you to post some design emails to the
|
|
||||||
[mailing list], and get feedback on them, both before applying, and during
|
|
||||||
the "community bonding period" between acceptance and official start.
|
|
||||||
|
|
||||||
* You must have made progress and committed significant code before the
|
|
||||||
mid-term point and by the final.
|
|
||||||
|
|
||||||
* We require that accepted contributors to maintain a blog, where you are
|
|
||||||
expected to write about your project *WEEKLY*. This is a way to measure
|
|
||||||
progress and for the community at large to be able to help you. GSoC is
|
|
||||||
*NOT* a private contract between your mentor and you.
|
|
||||||
|
|
||||||
* You must be active in the community on IRC and the [mailing list].
|
|
||||||
|
|
||||||
* You are expected to work on development publicly, and to push commits to the
|
|
||||||
project on a regular basis. Depending on the project and what your mentor
|
|
||||||
agrees to, these can be published directly to the project or to a public
|
|
||||||
repository such as Gitlab or Github. If you are not publishing directly to
|
|
||||||
the project codebase, be aware that we do not want large dumps of code that
|
|
||||||
need to be rushed to meet the mid-term and final goals.
|
|
||||||
|
|
||||||
We don't expect our contributors to be experts in our problem domain, but we
|
|
||||||
don't want you to fail because some basic misunderstanding was in your way of
|
|
||||||
completing the task.
|
|
||||||
|
|
||||||
|
|
||||||
## Projects
|
|
||||||
|
|
||||||
There are many development tasks available in coreboot. We prepared some ideas
|
|
||||||
for Summer of Code projects. These are projects that we think can be managed in
|
|
||||||
the timeline of GSoC, and they cover areas where coreboot is trying to reach
|
|
||||||
new users and new use cases.
|
|
||||||
|
|
||||||
Of course your application does not have to be based on any of the ideas listed.
|
|
||||||
It is entirely possible that you have a great idea that we just didn't think of
|
|
||||||
yet. Please let us know!
|
|
||||||
|
|
||||||
The blog posts related to previous GSoC projects might give some insights to
|
|
||||||
what it is like to be a coreboot GSoC contributor.
|
|
||||||
|
|
||||||
|
|
||||||
## coreboot Summer of Code Application
|
|
||||||
|
|
||||||
coreboot welcomes contributors from all backgrounds and levels of experience.
|
|
||||||
|
|
||||||
Your application should include a complete project proposal. You should
|
|
||||||
document that you have the knowledge and the ability to complete your proposed
|
|
||||||
project. This may require a little research and understanding of coreboot prior
|
|
||||||
to sending your application. The community and coreboot project mentors are your
|
|
||||||
best resource in fleshing out your project ideas and helping with a project
|
|
||||||
timeline. We recommend that you get feedback and recommendations on your
|
|
||||||
proposal before the application deadline.
|
|
||||||
|
|
||||||
Please complete the standard GSoC application and project proposal. Provide the
|
|
||||||
following information as part of your application. Make sure to provide multiple
|
|
||||||
ways of communicating in case your equipment (such as a laptop) is lost,
|
|
||||||
damaged, or stolen, or in case of a natural disaster that disrupts internet
|
|
||||||
service. You risk automatically failing if your mentor cannot contact you and if
|
|
||||||
you cannot provide updates according to GSoC deadlines.

## Mentors
|
|
||||||
|
|
||||||
Each accepted project will have at least one mentor. We will match mentors and
|
|
||||||
contributors based on the project and experience level. If possible, we also
|
|
||||||
will try to match their time zones.
|
|
||||||
|
|
||||||
Mentors are expected to stay in frequent contact with the contributor and
|
|
||||||
provide guidance such as code reviews, pointers to useful documentation, etc.
|
|
||||||
This should generally be a time commitment of several hours per week.
|
|
||||||
|
|
||||||
Some projects might have more than one mentor, who can serve as a backup. They
|
|
||||||
are expected to coordinate with each other and a contributor on a regular basis,
|
|
||||||
and keep track of the contributor process. They should be able to take over
|
|
||||||
mentoring duty if one of the mentors is unavailable (vacations, sickness,
|
|
||||||
emergencies).
|
|
||||||
|
|
||||||
|
|
||||||
### Volunteering to be a mentor
|
|
||||||
|
|
||||||
If you'd like to volunteer to be a mentor, please read the [GSoC Mentor Guide].
|
|
||||||
This will give you a better idea of expectations, and where to go for help.
|
|
||||||
After that, contact Org Admins (see coreboot contacts section above).
|
|
||||||
|
|
||||||
The following coreboot developers have volunteered to be GSoC 2022 mentors.
|
|
||||||
Please stop by in our community forums and say hi to them and ask them
|
|
||||||
questions.

# CBFS SMBIOS hooks
|
|
||||||
|
|
||||||
The document describes the coreboot options how to make CBFS files populate
|
|
||||||
platform-unique SMBIOS data.
|
|
||||||
|
|
||||||
## SMBIOS Serial Number
|
|
||||||
|
|
||||||
The [DMTF SMBIOS specification] defines a field in the type 1 System
|
|
||||||
Information and type 2 Baseboard Information called Serial Number. It
|
|
||||||
is a null-terminated string field assumed to be unique per platform. Certain
|
|
||||||
mainboard ports have SMBIOS hooks to generate the Serial Numbers from external
|
|
||||||
data, e.g. Lenovo Thinkpads (see DRIVER_LENOVO_SERIALS). This driver aims to
|
|
||||||
provide an option to populate the Serial Numbers from CBFS for boards that
|
|
||||||
can't generate the it from any source.
|
|
||||||
|
|
||||||
### Usage
|
|
||||||
|
|
||||||
In the coreboot configuration menu (`make menuconfig`) go to `Generic Drivers`
|
|
||||||
and select an option `Serial number in CBFS`. The Kconfig system will enable
|
|
||||||
`DRIVERS_GENERIC_CBFS_SERIAL` and the relevant code parts will be compiled into
|
|
||||||
coreboot image.
|
|
||||||
|
|
||||||
After the coreboot build for your board completes, use the cbfstool to include
|
|
||||||
the file containing the serial number:
|
|
||||||
|
|
||||||
```shell
|
|
||||||
./build/cbfstool build/coreboot.rom add -n serial_number -t raw -f /path/to/serial_file.txt
|
|
||||||
```
|
|
||||||
|
|
||||||
Where `serial_file.txt` is the unterminated string representation of the SMBIOS
|
|
||||||
type 1 or type 2 Serial Number, e.g. `5Q4Q7Y1`. If you use vboot with 1 or 2 RW
|
|
||||||
partitions you will have to specify the RW regions where the file is going to
|
|
||||||
be added too. By default the RW CBFS partitions are truncated, so the files
|
|
||||||
would probably not fit, one needs to expand them first.
|
|
||||||
|
|
||||||
```shell
|
|
||||||
./build/cbfstool build/coreboot.rom expand -r FW_MAIN_A
|
|
||||||
./build/cbfstool build/coreboot.rom add -n serial_number -t raw \
|
|
||||||
-f /path/to/serial_file.txt -r FW_MAIN_A
|
|
||||||
./build/cbfstool build/coreboot.rom truncate -r FW_MAIN_A
|
|
||||||
|
|
||||||
./build/cbfstool build/coreboot.rom expand -r FW_MAIN_B
|
|
||||||
./build/cbfstool build/coreboot.rom add -n serial_number -t raw \
|
|
||||||
-f /path/to/serial_file.txt -r FW_MAIN_B
|
|
||||||
./build/cbfstool build/coreboot.rom truncate -r FW_MAIN_B
|
|
||||||
```
|
|
||||||
|
|
||||||
By default cbfstool adds files to COREBOOT region only, so when vboot is
|
|
||||||
enabled and the platform is booting from RW partition, the file would not be
|
|
||||||
picked up by the driver.
|
|
||||||
|
|
||||||
One may retrieve the Serial Number from running system (if it exists) using one
|
|
||||||
of the following commands:
|
|
||||||
|
|
||||||
```shell
|
|
||||||
# Type 1
|
|
||||||
echo -n `sudo dmidecode -s system-serial-number` > serial_file.txt
|
|
||||||
# OR Type 2
|
|
||||||
echo -n `sudo dmidecode -s baseboard-serial-number` > serial_file.txt
|
|
||||||
```
|
|
||||||
|
|
||||||
Ensure the file does not end with whitespaces like LF and/or CR. The above
|
|
||||||
commands will not add any whitespaces. The driver automatically terminates the
|
|
||||||
Serial Number with the NULL character. If the CBFS file is not present, the
|
|
||||||
driver will fall back to the string defined in `MAINBOARD_SERIAL_NUMBER` build
|
|
||||||
option.
|
|
||||||
|
|
||||||
Please note that this driver provides `smbios_mainboard_serial_number` hook
|
|
||||||
overriding the default implementation which returns `MAINBOARD_SERIAL_NUMBER`
|
|
||||||
build option. If you wish to populate only type 2 Serial Number field your
|
|
||||||
board code needs to implement `smbios_system_serial_number`, otherwise the weak
|
|
||||||
implementation of `smbios_system_serial_number` will call
|
|
||||||
`smbios_mainboard_serial_number` from the `DRIVERS_GENERIC_CBFS_SERIAL`
|
|
||||||
implementation overriding it. So selecting the `DRIVERS_GENERIC_CBFS_SERIAL`
|
|
||||||
has a side-effect of populating both SMBIOS type 1 and type 2 Serial Numbers
|
|
||||||
if the board does not implement its own `smbios_system_serial_number`.
|
|
||||||
|
|
||||||
There is also SMBIOS type 3 Chassis Information Serial Number, but it is not
|
|
||||||
populated by `DRIVERS_GENERIC_CBFS_SERIAL` nor by the default weak
|
|
||||||
implementation (returns empty string). If you wish to populate type 3 Serial
|
|
||||||
Number, your board code should override the default
|
|
||||||
`smbios_chassis_serial_number` weak implementation.
|
|
||||||
|
|
||||||
## SMBIOS System UUID
|
|
||||||
|
|
||||||
The [DMTF SMBIOS specification] defines a field in the type 1 System
|
|
||||||
Information Structure called System UUID. It is a 16 bytes value compliant with
|
|
||||||
[RFC4122] and assumed to be unique per platform. Certain mainboard ports have
|
|
||||||
SMBIOS hooks to generate the UUID from external data, e.g. Lenovo Thinkpads
|
|
||||||
(see DRIVER_LENOVO_SERIALS). This driver aims to provide an option to populate
|
|
||||||
the UUID from CBFS for boards that can't generate the UUID from any source.
|
|
||||||
|
|
||||||
### Usage
|
|
||||||
|
|
||||||
In the coreboot configuration menu (`make menuconfig`) go to `Generic Drivers`
|
|
||||||
and select an option `System UUID in CBFS`. The Kconfig system will enable
|
|
||||||
`DRIVERS_GENERIC_CBFS_UUID` and the relevant code parts will be compiled into
|
|
||||||
coreboot image.
|
|
||||||
|
|
||||||
After the coreboot build for your board completes, use the cbfstool to include
|
|
||||||
the file containing the UUID:
|
|
||||||
|
|
||||||
```shell
|
|
||||||
./build/cbfstool build/coreboot.rom add -n system_uuid -t raw -f /path/to/uuid_file.txt
|
|
||||||
```
|
|
||||||
|
|
||||||
Where `uuid_file.txt` is the unterminated string representation of the SMBIOS
|
|
||||||
type 1 UUID, e.g. `4c4c4544-0051-3410-8051-b5c04f375931`. If you use vboot with
|
|
||||||
1 or 2 RW partitions you will have to specify the RW regions where the file is
|
|
||||||
going to be added too. By default the RW CBFS partitions are truncated, so the
|
|
||||||
files would probably not fit, one needs to expand them first.
|
|
||||||
|
|
||||||
```shell
|
|
||||||
./build/cbfstool build/coreboot.rom expand -r FW_MAIN_A
|
|
||||||
./build/cbfstool build/coreboot.rom add -n system_uuid -t raw \
|
|
||||||
-f /path/to/uuid_file.txt -r FW_MAIN_A
|
|
||||||
./build/cbfstool build/coreboot.rom truncate -r FW_MAIN_A
|
|
||||||
|
|
||||||
./build/cbfstool build/coreboot.rom expand -r FW_MAIN_B
|
|
||||||
./build/cbfstool build/coreboot.rom add -n system_uuid -t raw \
|
|
||||||
-f /path/to/uuid_file.txt -r FW_MAIN_B
|
|
||||||
./build/cbfstool build/coreboot.rom truncate -r FW_MAIN_B
|
|
||||||
```
|
|
||||||
|
|
||||||
By default cbfstool adds files to COREBOOT region only, so when vboot is
|
|
||||||
enabled and the platform is booting from RW partition, the file would not be
|
|
||||||
picked up by the driver.
|
|
||||||
|
|
||||||
One may retrieve the UUID from running system (if it exists) using the
|
|
||||||
following command:
|
|
||||||
|
|
||||||
```shell
|
|
||||||
echo -n `sudo dmidecode -s system-uuid` > uuid_file.txt
|
|
||||||
```
|
|
||||||
|
|
||||||
The above command ensures the file does not end with whitespaces like LF and/or
|
|
||||||
CR. The above command will not add any whitespaces. But the driver will handle
|
|
||||||
situations where up to 2 additional bytes like CR and LF will be included in
|
|
||||||
the file. Any more than that will make the driver fail to populate UUID in
|
|
||||||
SMBIOS.

# Driver Devicetree Entries
|
|
||||||
|
|
||||||
Let's take a look at an example entry from
|
|
||||||
``src/mainboard/google/hatch/variants/hatch/overridetree.cb``:
|
|
||||||
|
|
||||||
```
|
|
||||||
device pci 15.0 on
|
|
||||||
chip drivers/i2c/generic
|
|
||||||
register "hid" = ""ELAN0000""
|
|
||||||
register "desc" = ""ELAN Touchpad""
|
|
||||||
register "irq" = "ACPI_IRQ_LEVEL_LOW(GPP_A21_IRQ)"
|
|
||||||
register "detect" = "1"
|
|
||||||
register "wake" = "GPE0_DW0_21"
|
|
||||||
device i2c 15 on end
|
|
||||||
end
|
|
||||||
end # I2C #0
|
|
||||||
```
|
|
||||||
|
|
||||||
When this entry is processed during ramstage, it will create a device in the
|
|
||||||
ACPI SSDT table (all devices in devicetrees end up in the SSDT table). The ACPI
|
|
||||||
generation routines in coreboot actually generate the raw bytecode that
|
|
||||||
represents the device's structure, but looking at ASL code is easier to
|
|
||||||
understand; see below for what the disassembled bytecode looks like:
|
|
||||||
|
|
||||||
```
|
|
||||||
Scope (\_SB.PCI0.I2C0)
|
|
||||||
{
|
|
||||||

|
|
||||||

|
||||||

|
||||||

0x03 // Sleep state S3
|
|
||||||
})
|
|
||||||
}
|
|
||||||
}
|
|
||||||
```
|
|
||||||
|
|
||||||
You can see it generates \_HID, \_UID, \_DDN, \_STA, \_CRS, \_S0W, and \_PRW
|
|
||||||
names/methods in the Device's scope.
|
|
||||||
|
|
||||||
## Utilizing a device driver
|
|
||||||
|
|
||||||
The device driver must be enabled for your build. There will be a CONFIG option
|
|
||||||
in the Kconfig file in the directory that the driver is in (e.g.,
|
|
||||||
``src/drivers/i2c/generic`` contains a Kconfig file; the option here is named
|
|
||||||
CONFIG_DRIVERS_I2C_GENERIC). The config option will need to be added to your
|
|
||||||
mainboard's Kconfig file (e.g., ``src/mainboard/google/hatch/Kconfig``) in order
|
|
||||||
to be compiled into your build.
|
|
||||||
|
|
||||||
## Diving into the above example:
|
|
||||||
|
|
||||||
Let's take a look at how the devicetree language corresponds to the generated
|
|
||||||
ASL.
|
|
||||||
|
|
||||||
First, note this:
|
|
||||||
|
|
||||||
```
|
|
||||||
chip drivers/i2c/generic
|
|
||||||
```
|
|
||||||
|
|
||||||
This means that the device driver we're using has a corresponding structure,
|
|
||||||
located at ``src/drivers/i2c/generic/chip.h``, named **struct
|
|
||||||
drivers_i2c_generic_config** and it contains many properties you can specify to
|
|
||||||
be included in the ACPI table.
|
|
||||||
|
|
||||||
### hid
|
|
||||||
|
|
||||||
```
|
|
||||||
register "hid" = ""ELAN0000""
|
|
||||||
```
|
|
||||||
|
|
||||||
This corresponds to **const char \*hid** in the struct. In the ACPI ASL, it
|
|
||||||
translates to:
|
|
||||||
|
|
||||||
```
|
|
||||||
Name (_HID, "ELAN0000") // _HID: Hardware ID
|
|
||||||
```
|
|
||||||
|
|
||||||
under the device. **This property is used to match the device to its driver
|
|
||||||
during enumeration in the OS.**
|
|
||||||
|
|
||||||
### desc
|
|
||||||
|
|
||||||
```
|
|
||||||
register "desc" = ""ELAN Touchpad""
|
|
||||||
```
|
|
||||||
|
|
||||||
corresponds to **const char \*desc** and in ASL:
|
|
||||||
|
|
||||||
```
|
|
||||||
Name (_DDN, "ELAN Touchpad") // _DDN: DOS Device Name
|
|
||||||
```
|
|
||||||
|
|
||||||
### irq
|
|
||||||
|
|
||||||
It also adds the interrupt,
|
|
||||||
|
|
||||||
```
|
|
||||||
Interrupt (ResourceConsumer, Level, ActiveLow, Exclusive, ,, )
|
|
||||||
{
|
|
||||||
0x0000002D,
|
|
||||||
}
|
|
||||||
```
|
|
||||||
|
|
||||||
which comes from:
|
|
||||||
|
|
||||||
```
|
|
||||||
register "irq" = "ACPI_IRQ_LEVEL_LOW(GPP_A21_IRQ)"
|
|
||||||
```
|
|
||||||
|
|
||||||
The IRQ settings control the "Trigger" and "Polarity" settings seen above (level
|
|
||||||
means it is a level-triggered interrupt as opposed to
|
|
||||||
edge-triggered; active low means the interrupt is triggered when the signal is
|
|
||||||
low).
|
|
||||||
|
|
||||||
Also note that the IRQ names are SoC-specific, and you will need to
|
|
||||||
find the names in your SoC's header file. The ACPI_* macros are defined in
|
|
||||||
``src/arch/x86/include/acpi/acpi_device.h``.
|
|
||||||
|
|
||||||
Using a GPIO as an IRQ requires that it is configured in coreboot correctly.
|
|
||||||
This is often done in a mainboard-specific file named ``gpio.c``.
|
|
||||||
|
|
||||||
AMD platforms don't have the ability to route GPIOs to the IO-APIC. Instead the
|
|
||||||
GPIO controller needs to be used directly. You can do this by setting the
|
|
||||||
`irq_gpio` register and using the `ACPI_GPIO_IRQ_X_X` macros.
|
|
||||||
|
|
||||||
i.e.,
|
|
||||||
```
|
|
||||||
register "irq_gpio" = "ACPI_GPIO_IRQ_EDGE_LOW(GPIO_40)"
|
|
||||||
```
|
|
||||||
|
|
||||||
### detect
|
|
||||||
|
|
||||||
The next register is:
|
|
||||||
|
|
||||||
```
|
|
||||||
register "detect" = "1"
|
|
||||||
```
|
|
||||||
|
|
||||||
This flag tells the I2C driver that it should attempt to detect the presence of
|
|
||||||
the device (using an I2C zero-byte write), and only generate a SSDT entry if the
|
|
||||||
device is actually present. This alleviates the OS from having to determine if
|
|
||||||
a device is present or not (ChromeOS/Linux) and prevents resource conflict/
|
|
||||||
driver issues (Windows).
|
|
||||||
|
|
||||||
Currently, the detect feature works and is hooked up for all I2C touchpads,
|
|
||||||
and should be used any time a board has multiple touchpad options.
|
|
||||||
I2C audio devices should also work without issue.
|
|
||||||
|
|
||||||
Touchscreens can use this feature as well, but special care is needed to
|
|
||||||
implement the proper power sequencing for the device to be detected. Generally,
|
|
||||||
this means driving the enable GPIO high and holding the reset GPIO low in early
|
|
||||||
GPIO init (bootblock/romstage), then releasing reset in ramstage. The first
|
|
||||||
mainboards in the tree to implement this are google/skyrim and google/guybrush.
|
|
||||||
This feature has also been used in downstream forks without issue for some time
|
|
||||||
now on several other boards.
|
|
||||||
|
|
||||||
### wake
|
|
||||||
|
|
||||||
The last register is:
|
|
||||||
|
|
||||||
```
|
|
||||||
register "wake" = "GPE0_DW0_21"
|
|
||||||
```
|
|
||||||
|
|
||||||
which indicates that the method of waking the system using the touchpad will be
|
|
||||||
through a GPE, #21 associated with DW0, which is set up in devicetree.cb from
|
|
||||||
this example. The "21" indicates GPP_X21, where GPP_X is mapped onto DW0
|
|
||||||
elsewhere in the devicetree.
|
|
||||||
|
|
||||||
### device
|
|
||||||
|
|
||||||
The last bit of the definition of that device includes:
|
|
||||||
|
|
||||||
```
|
|
||||||
device i2c 15 on end
|
|
||||||
```
|
|
||||||
|
|
||||||
which means it's an I2C device, with 7-bit address 0x15, and the device is "on",
|
|
||||||
meaning it will be exposed in the ACPI table. The PCI device that the
|
|
||||||
controller is located in determines which I2C bus the device is expected to be
|
|
||||||
found on. In this example, this is I2C bus 0. This also determines the ACPI
|
|
||||||
"Scope" that the device names and methods will live under, in this case
|
|
||||||
"\_SB.PCI0.I2C0".
|
|
||||||
|
|
||||||
## Wake sources
|
|
||||||
|
|
||||||
The ACPI spec defines two methods to describe how a device can wake the system.
|
|
||||||
Only one of these methods should be used, otherwise duplicate wake events will
|
|
||||||
be generated.
|
|
||||||
|
|
||||||
### Using GPEs as a wake source
|
|
||||||
|
|
||||||
The `wake` property specified above is used to tell the ACPI subsystem that the
|
|
||||||
device can use a GPE to wake the system. The OS can control whether to enable
|
|
||||||
or disable the wake source by unmasking/masking off the GPE.
|
|
||||||
|
|
||||||
The `GPIO` -> `GPE` mapping must be configured in firmware. On AMD platforms this is
|
|
||||||
generally done by a mainboard specific `gpio.c` file that defines the GPIO
|
|
||||||
using `PAD_SCI`. The `GPIO` -> `GPE` mapping is returned by the
|
|
||||||
`soc_get_gpio_event_table` method that is defined in the SoC specific `gpio.c`
|
|
||||||
file. On Intel platforms, you fill in the `pmc_gpe0_dw0`, `pmc_gpe0_dw1`, and
|
|
||||||
`pmc_gpe0_dw2` fields in the devicetree to map 3 GPIO communities to `tier-1`
|
|
||||||
GPEs (the rest are available as `tier-2` GPEs).
|
|
||||||
|
|
||||||
Windows has a large caveat when using this method. If you use the `gpio_irq`
|
|
||||||
property to define a `GpioInt` in the `_CRS`, and then use the `wake` property
|
|
||||||
to define a `GPE`, Windows will
|
|
||||||
[BSOD](https://github.com/MicrosoftDocs/windows-driver-docs/blob/staging/windows-driver-docs-pr/debugger/bug-check-0xa5--acpi-bios-error.md)
|
|
||||||
complaining about an invalid ACPI configuration.
|
|
||||||
> 0x1000D - A device used both GPE and GPIO interrupts, which is not supported.
|
|
||||||
|
|
||||||
In order to avoid this error, you should use the `irq` property instead. AMD
|
|
||||||
platforms don't support routing GPIOs to the IO-APIC, so this workaround isn't
|
|
||||||
feasible. The other option is to use a wake capable GPIO as described below.
|
|
||||||
|
|
||||||
### Using GPIO interrupts as a wake source
|
|
||||||
|
|
||||||
The `ACPI_IRQ_WAKE_{EDGE,LEVEL}_{LOW,HIGH}` macros can be used when setting the
|
|
||||||
`irq` or `gpio_irq` properties. This ends up setting `ExclusiveAndWake` or
|
|
||||||
`SharedAndWake` on the `Interrupt` or `GpioInt` ACPI resource.
|
|
||||||
|
|
||||||
This method has a few caveats:
|
|
||||||
* On Intel and AMD platforms the IO-APIC can't wake the system. This means using
|
|
||||||
the `ACPI_IRQ_WAKE_*` macros with the `irq` property won't actually wake the
|
|
||||||
system. Instead you need to use the `gpio_irq` property, or a `GPE` as
|
|
||||||
described above.
|
|
||||||
* The OS needs to know how to enable the `wake` bit on the GPIO. For linux this
|
|
||||||
means the platform specific GPIO controller driver must implement the
|
|
||||||
`irq_set_wake` callback. For AMD systems this wasn't
|
|
||||||
[implemented](https://github.com/torvalds/linux/commit/d62bd5ce12d79bcd6a6c3e4381daa7375dc21158)
|
|
||||||
until linux v5.15. If the controller doesn't define this callback, it's
|
|
||||||
possible for the firmware to manually set the `wake` bit on the GPIO. This is
|
|
||||||
often done in a mainboard-specific file named `gpio.c`. This is not
|
|
||||||
recommended because then it's not possible for the OS to disable the wake
|
|
||||||
source.
|
|
||||||
* As of
|
|
||||||
[linux v6.0-rc5](https://github.com/torvalds/linux/releases/tag/v6.0-rc5),
|
|
||||||
the ACPI subsystem doesn't take the interrupt `wake` bit into account when
|
|
||||||
deciding on which power state to put the device in before suspending the
|
|
||||||
system. This means that if you define a power resource for a device via
|
|
||||||
`has_power_resource`, `enable_gpio`, etc, then the linux kernel will place the
|
|
||||||
device into D3Cold. i.e., power off the device.
|
|
||||||
|
|
||||||
## Other auto-generated names
|
|
||||||
|
|
||||||
(see [ACPI specification
|
|
||||||
6.3](https://uefi.org/sites/default/files/resources/ACPI_6_3_final_Jan30.pdf)
|
|
||||||
for more details on ACPI methods)
|
|
||||||
|
|
||||||
### _S0W (S0 Device Wake State)
|
|
||||||
\_S0W indicates the deepest S0 sleep state this device can wake itself from,
|
|
||||||
which in this case is `ACPI_DEVICE_SLEEP_D3_HOT`, representing _D3hot_.
|
|
||||||
D3Hot means the `PR3` power resources are still on and the device is still
|
|
||||||
responsive on the bus. For i2c devices this is generally the same state as `D0`.
|
|
||||||
|
|
||||||
### \_PRW (Power Resources for Wake)
|
|
||||||
\_PRW indicates the power resources and events required for wake. There are no
|
|
||||||
dependent power resources, but the GPE (GPE0_DW0_21) is mentioned here (0x15),
|
|
||||||
as well as the deepest sleep state supporting waking the system (3), which is
|
|
||||||
S3.
|
|
||||||
|
|
||||||
### \_STA (Status)
|
|
||||||
The \_STA method is generated automatically, and its values, 0xF, indicates the
|
|
||||||
following:
|
|
||||||
|
|
||||||
Bit [0] – Set if the device is present.
|
|
||||||
Bit [1] – Set if the device is enabled and decoding its resources.
|
|
||||||
Bit [2] – Set if the device should be shown in the UI.
|
|
||||||
Bit [3] – Set if the device is functioning properly (cleared if device failed its diagnostics).
|
|
||||||
|
|
||||||
### \_CRS (Current resource settings)
|
|
||||||
The \_CRS method is generated automatically, as the driver knows it is an I2C
|
|
||||||
controller, and so specifies how to configure the controller for proper
|
|
||||||
operation with the touchpad.
|
|
||||||
|
|
||||||
```
|
|
||||||
Name (_CRS, ResourceTemplate () // _CRS: Current Resource Settings
|
|
||||||
{
|
|
||||||
I2cSerialBusV2 (0x0015, ControllerInitiated, 400000,
|
|
||||||
AddressingMode7Bit, "\\_SB.PCI0.I2C0",
|
|
||||||
0x00, ResourceConsumer, , Exclusive, )
|
|
||||||
```

## OpenSecurityTraining2
|
|
||||||
|
|
||||||
OpenSecurityTraining2 is dedicated to sharing training material for any topic
|
|
||||||
related to computer security, including coreboot.
|
|
||||||
|
|
||||||
There are various ways to learn firmware, some are more efficient than others,
|
|
||||||
depending on the people. Before going straight to practice and experimenting
|
|
||||||
with hardware, it can be beneficial to learn the basics of computing. OST2
|
|
||||||
focuses on conveying computer architecture and security information in the form
|
|
||||||
of structured instructor-led classes, available to everyone for free.

allowing anyone to use the material however they see fit, so long as they share
|
|
||||||
modified works back to the community.

# Flashing firmware standalone
|
||||||
|
|
||||||
|
If none of the other methods work, there are three possibilities:
|
||||||
|
|
||||||
|
## Desolder
|
||||||
|
You must remove or desolder the flash IC before you can flash it.
|
||||||
|
It's recommended to solder a socket in place of the flash IC.
|
||||||
|
|
||||||
|
When flashing the IC, always connect all input pins.
|
||||||
|
If in doubt, pull /WP, /HOLD, /RESET and alike up towards Vcc.
|
||||||
|
|
||||||
|
## SPI flash emulator
|
||||||
|
If you are a developer, you might want to use an [EM100Pro] instead, which sets
|
||||||
|
the onboard flash on hold, and allows to run custom firmware.
|
||||||
|
It provides a very fast development cycle without actually writing to flash.
|
||||||
|
|
||||||
|
## SPI flash overwrite
|
||||||
|
It is possible to set the onboard flash on hold and use another flash chip.
|
||||||
|
Connect all lines one-to-one, except /HOLD. Pull /HOLD of the soldered flash IC
|
||||||

# Flashing firmware tutorial
|
||||||
|
|
||||||
|
Updating the firmware is possible using the **internal method**, where the updates
|
||||||
|
happen from a running system, or using the **external method**, where the system
|
||||||
|
is in a shut down state and an external programmer is attached to write into the
|
||||||
|
flash IC.
|
||||||
|
|
||||||
|
## Contents
|
||||||
|
|
||||||
|
* [Flashing internally](int_flashrom.md)
|
||||||
|
* [Flashing firmware standalone](ext_standalone.md)
|
||||||
|
* [Flashing firmware externally supplying direct power](ext_power.md)
|
||||||
|
* [Flashing firmware externally without supplying direct power](no_ext_power.md)
|
||||||
|
|
||||||
|
## General advice
|
||||||
|
|
||||||
|
* It's recommended to only flash the BIOS region.
|
||||||
|
* Always verify the firmware image.
|
||||||
|
* If you flash externally and have transmission errors:
|
||||||
|
* Use short wires
|
||||||
|
* Reduce clock frequency
|
||||||
|
* Check power supply
|
||||||
|
* Make sure that there are no other bus masters (EC, ME, SoC, ...)
|
||||||
|
|
||||||
|
## Internal method
|
||||||
|
|
||||||
|
This method using [flashrom] is available on many platforms, as long as they
|
||||||
|
aren't locked down.
|
||||||
|
|
||||||
|
There are various protection schemes that make it impossible to modify or
|
||||||
|
replace a firmware from a running system. coreboot allows to disable these
|
||||||
|
mechanisms, making it possible to overwrite (or update) the firmware from a
|
||||||
|
running system.
|
||||||
|
|
||||||
|
Usually you must use the **external method** once to install a retrofitted
|
||||||
|
coreboot and then you can use the **internal method** for future updates.
|
||||||
|
|
||||||
|
There are multiple ways to update the firmware:
|
||||||
|
* Using flashrom's *internal* programmer to directly write into the firmware
|
||||||
|
flash IC, running on the target machine itself
|
||||||
|
* A proprietary software to update the firmware, running on the target machine
|
||||||
|
itself
|
||||||
|
* A UEFI firmware update capsule
|
||||||
|
|
||||||
|
More details on flashrom's
|
||||||
|
* [internal programmer](int_flashrom.md)
|
||||||
|
|
||||||
|
## External method
|
||||||
|
|
||||||
|
External flashing is possible on many platforms, but requires disassembling
|
||||||
|
the target hardware. You need to buy a flash programmer, that
|
||||||
|
exposes the same interface as your flash IC (likely SPI).
|
||||||
|
|
||||||
|
Please also have a look at the mainboard-specific documentation for details.
|
||||||
|
|
||||||
|
After exposing the firmware flash IC, read the schematics and use one of the
|
||||||
|
possible methods:
|
||||||
|
|
||||||
|
* [Flashing firmware standalone](ext_standalone.md)
|
||||||
|
* [Flashing firmware externally supplying direct power](ext_power.md)
|
||||||
|
* [Flashing firmware externally without supplying direct power](no_ext_power.md)
|
||||||
|
|
||||||
|
**WARNING:** Using the wrong method or accidentally using the wrong pinout might
|
||||||
|
permanently damage your hardware!
|
||||||
|
|
||||||
|
**WARNING:** Do not rely on dots *painted* on flash ICs to orient the pins!
|
||||||
|
Any dots painted on flash ICs may only indicate if they've been tested. Dots
|
||||||
|
that appear in datasheets to indicate pin 1 correspond to some kind of physical
|
||||||
|
marker, such as a drilled hole, or one side being more flat than the other.
|
||||||
|
|
||||||
|
## Using a layout file
|
||||||
|
On platforms where the flash IC is shared with other components you might want
|
||||||
|
to write only a part of the flash IC. On Intel for example there are IFD, ME and
|
||||||
|
GBE which don't need to be updated to install coreboot.
|
||||||
|
To make [flashrom] only write the *bios* region, leaving Intel ME and Intel IFD
|
||||||
|
untouched, you can use a layout file, which can be created with ifdtool and a backup
|
||||||
|
of the original firmware.
|
||||||
|
|
||||||
|
```bash
|
||||||
|
ifdtool -f rom.layout backup.rom
|
||||||
|
```
|
||||||
|
|
||||||
|
and looks similar to:
|
||||||
|
|
||||||
|
```
|
||||||
|
00000000:00000fff fd
|
||||||
|
00500000:00bfffff bios
|
||||||
|
00003000:004fffff me
|
||||||
|
00001000:00002fff gbe
|
||||||
|
```
|
||||||
|
|
||||||
|
By specifying *-l* and *-i* [flashrom] writes a single region:
|
||||||
|
```bash
|
||||||
|
flashrom -l rom.layout -i bios -w coreboot.rom -p <programmer>
|
||||||
|
```
|
||||||
|
|
||||||
|
## Using an IFD to determine the layout
|
||||||
|
flashrom version 1.0 supports reading the layout from the IFD (first 4KiB of
|
||||||
|
the ROM). You don't need to manually specify a layout it, but it only works
|
||||||
|
under the following conditions:
|
||||||
|
|
||||||
|
* Only available on Intel ICH7+
|
||||||
|
* There's only one flash IC when flashing externally
|
||||||
|
|
||||||
|
```bash
|
||||||
|
flashrom --ifd -i bios -w coreboot.rom -p <programmer>
|
||||||
|
```

||||||

# Adding new devices to a device tree
|
|
||||||
|
|
||||||
## Introduction
|
|
||||||
|
|
||||||
ACPI exposes a platform-independent interface for operating systems to perform
|
|
||||||
power management and other platform-level functions. Some operating systems
|
|
||||||
also use ACPI to enumerate devices that are not immediately discoverable, such
|
|
||||||
as those behind I2C or SPI buses (in contrast to PCI). This document discusses
|
|
||||||
the way that coreboot uses the concept of a "device tree" to generate ACPI
|
|
||||||
tables for usage by the operating system.
|
|
||||||
|
|
||||||
## Devicetree and overridetree (if applicable)
|
|
||||||
|
|
||||||
For mainboards that are organized around a "reference board" or "baseboard"
|
|
||||||
model (see ``src/mainboard/google/octopus`` or ``hatch`` for examples), there is
|
|
||||||
typically a devicetree.cb file that all boards share, and any differences for a
|
|
||||||
specific board ("variant") are captured in the overridetree.cb file. Any
|
|
||||||
settings changed in the overridetree take precedence over those in the main
|
|
||||||
devicetree. Note, not all mainboards will have the devicetree/overridetree
|
|
||||||
distinction, and may only have a devicetree.cb file. Or you can always just
|
|
||||||
write the ASL (ACPI Source Language) code yourself.
|
|
||||||
|
|
||||||
### Naming and referencing devices
|
|
||||||
|
|
||||||
When declaring a device, it can optionally be given an alias that can be
|
|
||||||
referred to elsewhere. This is particularly useful to declare a device in one
|
|
||||||
device tree while allowing its configuration to be more easily changed in an
|
|
||||||
overlay. For instance, the AMD Picasso SoC definition
|
|
||||||
(`soc/amd/picasso/chipset.cb`) declares an IOMMU on a PCI bus that is disabled
|
|
||||||
by default:
|
|
||||||
|
|
||||||
```
|
|
||||||
chip soc/amd/picasso
|
|
||||||
device domain 0 on
|
|
||||||
...
|
|
||||||
device pci 00.2 alias iommu off end
|
|
||||||
...
|
|
||||||
end
|
|
||||||
end
|
|
||||||
```
|
|
||||||
|
|
||||||
A device based on this SoC can override the configuration for the IOMMU without
|
|
||||||
duplicating addresses, as in
|
|
||||||
`mainboard/google/zork/variants/baseboard/devicetree_trembyle.cb`:
|
|
||||||
|
|
||||||
```
|
|
||||||
chip soc/amd/picasso
|
|
||||||
device domain 0
|
|
||||||
...
|
|
||||||
device ref iommu on end
|
|
||||||
...
|
|
||||||
end
|
|
||||||
end
|
|
||||||
```
|
|
||||||
|
|
||||||
In this example the override simply enables the IOMMU, but it could also
|
|
||||||
set additional properties (or even add child devices) inside the IOMMU `device`
|
|
||||||
block.
|
|
||||||
|
|
||||||
---
|
|
||||||
|
|
||||||
It is important to note that devices that use `device ref` syntax to override
|
|
||||||
previous definitions of a device by alias must be placed at **exactly the same
|
|
||||||
location in the device tree** as the original declaration. If not, this will
|
|
||||||
actually create another device rather than overriding the properties of the
|
|
||||||
existing one. For instance, if the above snippet from `devicetree_trembyle.cb`
|
|
||||||
were written as follows:
|
|
||||||
|
|
||||||
```
|
|
||||||
chip soc/amd/picasso
|
|
||||||
# NOTE: not inside domain 0!
|
|
||||||
device ref iommu on end
|
|
||||||
end
|
|
||||||
```
|
|
||||||
|
|
||||||
Then this would leave the SoC's IOMMU disabled, and instead create a new device
|
|
||||||
with no properties as a direct child of the SoC.
|
|
||||||
|
|
||||||
## Device drivers
|
|
||||||
|
|
||||||
Platform independent device drivers are hooked up via entries in a devicetree.
|
|
||||||
See [Driver Devicetree Entries](../drivers/dt_entries.md) for more info.
|
|
||||||
|
|
||||||
## Notes
|
|
||||||
|
|
||||||
- **All fields that are left unspecified in the devicetree are initialized to
|
|
||||||
zero.**

# coreboot FAQ
|
|
||||||
|
|
||||||
## General coreboot questions
|
|
||||||
|
|
||||||
|
|
||||||
### What is coreboot?
|
|
||||||
|
|
||||||
coreboot is a free and open software project designed to initialize
|
|
||||||
computers and embedded systems in a fast, secure, and auditable fashion.
|
|
||||||
The focus is on minimal hardware initialization: to do only what is
|
|
||||||
absolutely needed, then pass control to other software (a payload, in
|
|
||||||
coreboot parlance) in order to boot the operating system securely.
|
|
||||||
|
|
||||||
|
|
||||||
### What is a coreboot payload?
|
|
||||||
|
|
||||||
coreboot itself does not deal with boot media such as hard-drives,
|
|
||||||
SSDs, or USB flash-drives, beyond initializing the underlying hardware.
|
|
||||||
So in order to actually boot an operating system, another piece of
|
|
||||||
software which does do those things must be used. coreboot supports
|
|
||||||
a large number of diverse payloads; see below for more details.
|
|
||||||
|
|
||||||
|
|
||||||
### Is coreboot the same as UEFI?
|
|
||||||
|
|
||||||
No. coreboot and UEFI are both system firmware that handle the
|
|
||||||
initialization of the hardware, but are otherwise not similar.
|
|
||||||
coreboot’s goal is to **just** initialize the hardware and exit.
|
|
||||||
This makes coreboot smaller and simpler, leading to faster boot times,
|
|
||||||
and making it easier to find and fix bugs. The result is a higher
|
|
||||||
overall security.
|
|
||||||
|
|
||||||
|
|
||||||
### What's the difference between coreboot and UEFI?
|
|
||||||
|
|
||||||
UEFI is actually a firmware specification, not a specific software
|
|
||||||
implementation. Intel, along with the rest of the Tianocore project,
|
|
||||||
has released an open-source implementation of the overall framework,
|
|
||||||
EDK2, but it does not come with hardware support. Most hardware running
|
|
||||||
UEFI uses a proprietary implementation built on top of EDK2.
|
|
||||||
|
|
||||||
coreboot does not implement the UEFI specification, but it can be used to
|
|
||||||
initialize the system, then launch a UEFI payload such as EDK2 in order
|
|
||||||
to provide UEFI boot services.
|
|
||||||
|
|
||||||
The UEFI specification also defines and allows for many things that are
|
|
||||||
outside of coreboot’s scope, including (but not limited to):
|
|
||||||
|
|
||||||
* Boot device selection
|
|
||||||
* Updating the firmware
|
|
||||||
* A CLI shell
|
|
||||||
* Network communication
|
|
||||||
* An integrated setup menu
|
|
||||||
|
|
||||||
|
|
||||||
### Can coreboot boot operating systems that require UEFI?
|
|
||||||
|
|
||||||
Yes, but... again, coreboot **just** initializes the hardware. coreboot
|
|
||||||
itself doesn’t load operating systems from storage media other than the
|
|
||||||
flash chip. Unlike UEFI, coreboot does not, and will not contain a Wi-Fi
|
|
||||||
driver or communicate directly with any sort of network. That sort of
|
|
||||||
functionality is not related to hardware initialization.
|
|
||||||
|
|
||||||
To boot operating systems that require UEFI, coreboot can be compiled with
|
|
||||||
EDK2 as the payload. This allows coreboot to perform the hardware init,
|
|
||||||
with EDK2 supplying the UEFI boot interface and runtime services to
|
|
||||||
the operating system.
|
|
||||||
|
|
||||||
|
|
||||||
### What non-UEFI payloads does coreboot support?
|
|
||||||
|
|
||||||
* SeaBIOS, behaves like a classic BIOS, allowing you to boot operating
|
|
||||||
systems that rely on the legacy interrupts.
|
|
||||||
|
|
||||||
* GRUB can be used as a coreboot payload, and is currently the most
|
|
||||||
common approach to full disk encryption (FDE).
|
|
||||||
|
|
||||||
* A Linux kernel and initramfs stored alongside coreboot in the boot
|
|
||||||
ROM can also be used as a payload. In this scenario coreboot
|
|
||||||
initializes hardware, loads Linux from boot ROM into RAM, and
|
|
||||||
executes it. The embedded Linux environment can look for a target OS
|
|
||||||
kernel to load from local storage or over a network and execute it
|
|
||||||
using kexec. This is sometimes called LinuxBoot.
|
|
||||||
|
|
||||||
* U-boot, depthcharge, FILO, etc.
|
|
||||||
|
|
||||||
There’s [https://doc.coreboot.org/payloads.html](https://doc.coreboot.org/payloads.html)
|
|
||||||
with a list, although it’s not complete.
|
|
||||||
|
|
||||||
|
|
||||||
### What does coreboot leave in memory after it's done initializing the hardware?
|
|
||||||
|
|
||||||
While coreboot tries to remove itself completely from memory after
|
|
||||||
finishing, some tables and data need to remain for the OS. coreboot
|
|
||||||
reserves an area in memory known as CBMEM, to save this data after it
|
|
||||||
has finished booting. This contains things such as the boot log, tables
|
|
||||||
that get passed to the payload, SMBIOS, and ACPI tables for the OS.
|
|
||||||
|
|
||||||
In addition to CBMEM, on X86 systems, coreboot will typically set up
|
|
||||||
SMM, which will remain resident after coreboot exits.
|
|
||||||
|
|
||||||
|
|
||||||
## Platforms
|
|
||||||
|
|
||||||
### What’s the best coreboot platform for a user?
|
|
||||||
|
|
||||||
The choice of the best coreboot platform for a user can vary depending
|
|
||||||
on their specific needs, preferences, and use cases.
|
|
||||||
|
|
||||||
Typically, people who want a system with a minimum of proprietary
|
|
||||||
firmware are restricted to older systems like the Lenovo X220, or more
|
|
||||||
expensive, non-x86 solutions like TALOS, from Raptor Engineering.
|
|
||||||
|
|
||||||
There are a number of companies selling modern systems, but those all
|
|
||||||
require more proprietary binaries in addition to coreboot (e.g., Intel
|
|
||||||
FSP). However, unlike the older ThinkPads, many of these newer devices
|
|
||||||
use open-source embedded controller (EC) firmware, so there are
|
|
||||||
tradeoffs with either option.
|
|
||||||
|
|
||||||
The coreboot project mantains a list of companies selling machines
|
|
||||||
which use coreboot on the [website](https://coreboot.org/users.html).
|
|
||||||
|
|
||||||
|
|
||||||
### What’s the best platform for coreboot development?
|
|
||||||
|
|
||||||
Similar to the best platform for users, the best platform for
|
|
||||||
developers very much depends on what a developer is trying to do.
|
|
||||||
|
|
||||||
* QEMU is generally the easiest platform for coreboot development, just
|
|
||||||
because it’s easy to run anywhere. However, it’s possible for things
|
|
||||||
to work properly in QEMU but fail miserably on actual hardware.
|
|
||||||
|
|
||||||
While laptops tend to be harder to develop than desktop platforms, a
|
|
||||||
majority of newer platforms on coreboot tend to be laptops. The
|
|
||||||
development difficulty is due to a few different factors:
|
|
||||||
|
|
||||||
1. The EC (Embedded Controller) is a specialized microcontroller that
|
|
||||||
typically handles keyboard and sometimes mouse input for a laptop.
|
|
||||||
It also controls many power management functions such as fans, USB-C
|
|
||||||
power delivery, etc. ECs run mainboard-specific firmware, which is
|
|
||||||
typically undocumented.
|
|
||||||
2. ThinkPads (X230, 30-series, 20-series, T430, T540, T520). Sandy
|
|
||||||
Bridge and Ivy Bridge are well-supported. Some may have
|
|
||||||
difficult-to-reach SPI flash chips. Boards with two flash chips (e.g.
|
|
||||||
30-series ThinkPads) are harder to externally reflash as one needs to
|
|
||||||
make sure the non-targeted flash chip remains disabled at all times.
|
|
||||||
The X230 is notoriously sensitive to external reflashing issues.
|
|
||||||
3. Laptops often lack a convenient method to obtain firmware boot logs.
|
|
||||||
One can use EHCI debug on older systems and Chromebook-specific
|
|
||||||
solutions for Chromebooks, but one often has to resort to flashconsole
|
|
||||||
(writing coreboot logs to the flash chip where coreboot resides). On
|
|
||||||
the other hand, several desktop mainboards still have a RS-232 serial
|
|
||||||
port.
|
|
||||||
|
|
||||||
Some of the easiest physical systems to use for coreboot development
|
|
||||||
are Chromebooks. Newer Chromebooks allow for debug without opening the
|
|
||||||
case. Look for SuzyQ Cables or SuzyQables or instructions on how to
|
|
||||||
build one. These cables only work on a specific port in a specific
|
|
||||||
orientation. Google [supplies
|
|
||||||
specifications](https://chromium.googlesource.com/chromiumos/third_party/hdctools/+/master/docs/ccd.md#SuzyQ-SuzyQable)
|
|
||||||
for these cables.

|
||||||
|
|
||||||

|
||||||
### What platforms does coreboot support?
|
|
||||||
|
|
||||||
The most accurate way to determine what systems coreboot supports is by
|
|
||||||
browsing the src/mainboard tree or running “make menuconfig” and going
|
|
||||||
through the “Mainboard” submenu. You can also search Gerrit to see if
|
|
||||||
there are any unmerged ports for your board.
|
|
||||||
|
|
||||||
There is also the board status page
|
|
||||||
([https://coreboot.org/status/board-status.html](https://coreboot.org/status/board-status.html)),
|
|
||||||
however this does not currently show supported board variants.

|
||||||

||||||

|
||||||
## coreboot Development
|
|
||||||
|
|
||||||
### Can coreboot be ported to [this board]?
|
|
||||||
|
|
||||||
The best way to determine if coreboot can be ported to a system is to
|
|
||||||
see if the processor and chipset is supported. The next step is to see
|
|
||||||
whether the system is locked to the proprietary firmware which comes
|
|
||||||
with the board.
|
|
||||||
|
|
||||||
Intel Platforms:
|
|
||||||
|
|
||||||
* coreboot only supports a few northbridges (back when northbridges
|
|
||||||
were on a separate package), and there's next to no support for
|
|
||||||
"server" platforms (multi-socket and similar things). Here's a list
|
|
||||||
of more recent supported Intel processors:
|
|
||||||
* Alder Lake (2021 - Core Gen 12)
|
|
||||||
* Apollo Lake (2016 - Atom)
|
|
||||||
* Baytrail (2014 - Atom)
|
|
||||||
* Braswell (2016 - Atom)
|
|
||||||
* Broadwell (2014 - Core Gen 5)
|
|
||||||
* Comet Lake (2019 - Core Gen 10)
|
|
||||||
* Cannon Lake (2018 - Core Gen 8/9)
|
|
||||||
* Denverton (2017)
|
|
||||||
* Elkhart lake (2021 - Atom)
|
|
||||||
* Haswell (2013 - Core Gen 4)
|
|
||||||
* Ivy Bridge (2012 - Core Gen 3)
|
|
||||||
* Jasper Lake (2021 - Atom)
|
|
||||||
* Kaby Lake (2016 - Core Gen 7/8)
|
|
||||||
* Meteor Lake (2023 - Gen 1 Ultra-mobile)
|
|
||||||
* Sandy Bridge (2011 - Core Gen 2)
|
|
||||||
* Sky Lake (2015 - Core Gen 6)
|
|
||||||
* Tiger Lake (2020 - Core Gen 11)
|
|
||||||
* Whiskey Lake (2018 - Core Gen 8)
|
|
||||||
|
|
||||||
* Intel Boot Guard is a security feature which tries to prevent loading
|
|
||||||
unauthorized firmware by the mainboard. If supported by the platform,
|
|
||||||
and the platform is supported by intelmetool, you should check if Boot
|
|
||||||
Guard is enabled. If it is, then getting coreboot to run will be
|
|
||||||
difficult or impossible even if it is ported. You can run
|
|
||||||
`intelmetool -b` on supported platforms to see if Boot Guard is
|
|
||||||
enabled (although it can fail because it wants to probe the ME
|
|
||||||
beforehand).
|
|
||||||
|
|
||||||
AMD Ryzen-based platforms:
|
|
||||||
|
|
||||||
* The AMD platforms Ryzen-based platforms unfortunately are currently
|
|
||||||
not well supported outside of the Chromebooks (and AMD reference
|
|
||||||
boards) currently in the tree.
|
|
||||||
The responsible teams are trying to fix this, but currently it's
|
|
||||||
**very** difficult to do a new port. Recent supported SoCs:
|
|
||||||
* Stoney Ridge
|
|
||||||
* Picasso
|
|
||||||
* Cezanne
|
|
||||||
* Mendocino
|
|
||||||
* Phoenix
|
|
||||||
|
|
||||||
General notes:
|
|
||||||
|
|
||||||
* Check the output of `lspci` to determine what processor/chipset
|
|
||||||
family your system has. Processor/chipset support is the most
|
|
||||||
important to determine if a board can be ported.
|
|
||||||
* Check the output of `superiotool` to see if it detects the Super I/O
|
|
||||||
on the system. You can also check board schematics and/or boardviews
|
|
||||||
if you can find them, or physically look at the mainboard for a chip
|
|
||||||
from one of the common superio vendors.
|
|
||||||
* Check what EC your system has (mostly applicable to laptops, but some
|
|
||||||
desktops have EC-like chips). You will likely need to refer to the
|
|
||||||
actual board or schematics/boardviews for this. Physical observation
|
|
||||||
is the most accurate identification procedure; software detection can
|
|
||||||
then be used to double-check if the chip is correct, but one should
|
|
||||||
not rely on software detection alone to identify an EC.
|
|
||||||

### How do I port coreboot to [this board]?
|
|
||||||
|
|
||||||
A critical piece for anyone attempting to do a board port is to make
|
|
||||||
sure that you have a method to recover your system from a failed flash.
|
|
||||||
|
|
||||||
We need an updated motherboard porting guide, but currently the guide
|
|
||||||
on the [wiki](https://www.coreboot.org/Motherboard_Porting_Guide) looks
|
|
||||||
to be the best reference.
|
|
||||||
|
|
||||||
At the moment, the best answer to this question is to ask for help on
|
|
||||||
one of the [various community
|
|
||||||
forums](https://doc.coreboot.org/community/forums.html).
|
|
||||||
|
|
||||||
|
|
||||||
### What about the Intel ME?
|
|
||||||
|
|
||||||
There seems to be a lot of FUD about what the ME can and can’t do.
|
|
||||||
coreboot currently does not have a clear recommendation on how to
|
|
||||||
handle the ME. We understand that there are serious concerns about the
|
|
||||||
ME, and would like to flatly recommend removing as much as possible,
|
|
||||||
however modifying the ME can cause serious stability issues.
|
|
||||||
|
|
||||||
Additionally, coreboot and the Intel ME are completely separate entites
|
|
||||||
which in many cases simply happen to occupy the same flash chip. It is
|
|
||||||
not necessary to run coreboot to modify the ME, and running coreboot
|
|
||||||
does not imply anything about the ME's operational state.
|
|
||||||
|
|
||||||
|
|
||||||
#### A word of caution about the modifying ME
|
|
||||||
|
|
||||||
Messing with the ME firmware can cause issues, and this is outside the
|
|
||||||
scope of the coreboot project.
|
|
||||||
|
|
||||||
If you do decide to modify the ME firmware, please make sure coreboot
|
|
||||||
works **before** messing with it. Even if the vendor boot firmware
|
|
||||||
works when the ME isn't operating normally, it's possible that coreboot
|
|
||||||
doesn't handle it the same way and something breaks. If someone asks
|
|
||||||
for help with coreboot and we think the ME state may be a factor, we'll
|
|
||||||
ask them to try reproducing the issue with the ME running normally to
|
|
||||||
reduce the number of variables involved. This is especially important
|
|
||||||
when flashing coreboot for the first time, as it's best for newbies to
|
|
||||||
start with small steps: start by flashing coreboot to the BIOS region
|
|
||||||
and leaving the remaining regions untouched, then tinker around with
|
|
||||||
coreboot options (e.g. other payloads, bootsplash, RAM overclock...),
|
|
||||||
or try messing with the ME firmware **without changing coreboot**.
|
|
||||||
|
|
||||||
Most people don't understand the implications of messing with the ME
|
|
||||||
firmware, especially the use of `me_cleaner`. We admit that we don't
|
|
||||||
know everything about the ME, but we try to understand it as much as
|
|
||||||
possible. The ME is designed to operate correctly with the HAP (or
|
|
||||||
AltMeDisable) bit set, and it will gracefully enter a debug state (not
|
|
||||||
normal, but not an error). However, when using `me_cleaner` to remove
|
|
||||||
parts of the ME firmware, the ME will often end up in an error state
|
|
||||||
because parts of its FW are missing. It is known that removing some of
|
|
||||||
these parts ([`EFFS` and `FCRS` on Cougar Point,
|
|
||||||
c.f.](https://review.coreboot.org/c/coreboot/+/27798/6/src/mainboard/asus/p8h61-m_lx/Kconfig#63))
|
|
||||||
can cause problems. We do not know whether the state the ME ends up in
|
|
||||||
after applying `me_cleaner` is as secure as the state the ME goes to
|
|
||||||
when only the HAP bit is set: the removed FW modules could contain
|
|
||||||
steps to lock down important settings for security reasons.
|
|
||||||
|
|
||||||
To sum up, **we do not recommend messing with the ME firmware**. But if
|
|
||||||
you have to, please use `ifdtool` to set the HAP bit initially before
|
|
||||||
progressing to `me_cleaner` if necessary.

Sign-off Procedure
|
|
||||||
------------------
|
|
||||||
The coreboot project employs a sign-off procedure similar to what is
|
|
||||||
used by the Linux kernel. Each gerrit commit requires a sign-off line
|
|
||||||
saying that the contributed code abides by the Developer's certificate
|
|
||||||
of origin, below.
|
|
||||||
```text
|
|
||||||
Signed-off-by: Random J Developer <random@developer.example.org>
|
|
||||||
```
|
|
||||||
|
|
||||||
Using '-s' with 'git commit' will automatically add a Signed-off-by line
|
|
||||||
to your commit message. Patches without a Signed-off-by should not be
|
|
||||||
pushed to gerrit, and will be rejected by coreboot's CI system.
|
|
||||||
|
|
||||||
You must use a known identity in the Signed-off-by line. Anonymous
|
|
||||||
contributions cannot be committed! This can be anything sufficient to
|
|
||||||
identify and contact the source of a contribution, such as your name or
|
|
||||||
an established alias/nickname. Refer to [this LKML thread] and the
|
|

Each GPIO Community has a Pad Configuration Lock register for a GPP allowing locking
|
|
||||||
specific register fields in the PAD configuration register.
|
|
||||||
|
|
||||||
The Pad Config Lock registers reset type is default hardcoded to **Power Good** and
|
|
||||||
it's **not** configurable by GPIO PAD DW0.PadRstCfg. Hence, it may appear that for a GPP,
|
|
||||||
the Pad Reset Config (DW0 Bit 31) is configured differently from `Power Good`.
|
|
||||||
|
|
||||||
This would create confusion where the Pad configuration is returned to its `default`
|
|
||||||
value but remains `locked`, this would prevent software to reprogram the GPP.
|
|
||||||
Additionally, this means software can't rely on GPIOs being reset by PLTRST# or Sx entry.
|
|
||||||
|
|
||||||
Hence, as per GPIO BIOS Writers Guide (BWG) it's recommended to change the Pad Reset
|
|
||||||
Configuration for lock GPP as `Power Good` so that pad configuration and lock bit are
|
|
||||||
always in sync and can be reset at the same time.

## Blob policy in the coreboot project
|
|
||||||
|
|
||||||
The goal of the coreboot project is to provide a FOSS firmware solution across
|
|
||||||
multiple CPU architectures, such as ARM, x86, and RISC-V. While fully open
|
|
||||||
source implementations for these architectures are encouraged and preferred,
|
|
||||||
we understand that a fully open implementation whereby every firmware component
|
|
||||||
is available as source code for modern platforms is not always feasible.
|
|
||||||
Different reasons inhibit the availability of fully open implementations,
|
|
||||||
including limited development resources, 3rd party license constraints of
|
|
||||||
IP blocks, or a legacy mindset of the silicon vendors.
|
|
||||||
|
|
||||||
It is important for the coreboot project to have support for modern CPU
|
|
||||||
platforms in order to provide a viable alternative for proprietary firmware
|
|
||||||
implementations. We do not have direct control over how hardware vendors design
|
|
||||||
their products, however we can provide an attractive alternative to the
|
|
||||||
expensive and complicated proprietary firmware model that exists today.
|
|
||||||
For modern platforms, we are largely dependent on the silicon
|
|
||||||
vendor to provide additional information on how to properly initialize the
|
|
||||||
hardware, as the required datasheets are often only available with an NDA.
|
|
||||||
Therefore, one possible way to have coreboot support for the latest platforms
|
|
||||||
is binary code (aka, a blob) provided by the silicon vendor. While we do
|
|
||||||
discourage this solution, it can be a door opener for coreboot’s support of a
|
|
||||||
given platform and thus keep coreboot functional on modern platforms. It is
|
|
||||||
clearly not the goal of the project to accept every blob a silicon vendor wishes
|
|
||||||
to use without question. On the contrary, each new blob needs to be examined
|
|
||||||
critically by the community, evaluating the need, risk, and alternative options.
|
|
||||||
|
|
||||||
Wherever possible, introducing new blobs should be avoided. That said, there
|
|
||||||
can be situations where a piece of code provided as a blob will enable the rest
|
|
||||||
of the fully open source firmware stack on a brand new platform. If blocking
|
|
||||||
this blob would lead to no support at all for the platform in question in
|
|
||||||
coreboot, this situation needs to be examined carefully. While these kinds
|
|
||||||
of discussion will be coordinated closely with the community (e.g. on the
|
|
||||||
mailing list or dedicated meetings), ultimately it is up to the leadership to
|
|
||||||
decide if there is no agreement between the community and the vendor pushing for
|
|
||||||
the new blob. This decision will be communicated on the mailing list.
|
|
||||||

||||||

# Operating our services
|
|
||||||
|
|
||||||
## Mailing list moderation
|
|
||||||
|
|
||||||
Our [mailing lists] experience the same barrage of spam mails than any
|
|
||||||
other email address. We do have a spam filter in front of it, and
|
|
||||||
since the lists require registration, spam ends up in the moderation
|
|
||||||
queue. But not only spam ends up there, sometimes users send inquiries
|
|
||||||
without registering first. It's a custom of the project to let these
|
|
||||||
through, so that such emails can be discussed. This requires manual
|
|
||||||
intervention.
|
|
||||||
|
|
||||||
This section describes the tasks related to mailing list management.
|
|
||||||
|
|
||||||
### Registration
|
|
||||||
|
|
||||||
To participate in mailing list moderation, you need to become a list
|
|
||||||
moderator or owner. This is up for the existing owners to handle and
|
|
||||||
if you want to contribute in that area, it might be best to bring it
|
|
||||||
up at the leadership meeting.
|
|
||||||
|
|
||||||
After gaining leadership approval, list admins can add you to the
|
|
||||||
appropriate group in the [mailing list backend] by selecting the list,
|
|
||||||
then User / group-name, and add your email address there.
|
|
||||||
|
|
||||||
### Regular tasks
|
|
||||||
|
|
||||||
Most of our lists are auto-subscribing, so users can register
|
|
||||||
themselves and finish the process by responding to the double-opt-in
|
|
||||||
email. Some lists are manually managed though. The [mailing list
|
|
||||||
backend] shows the number of open subscription requests for these
|
|
||||||
lists on the mailing list's main page.
|
|
||||||
|
|
||||||
It also provides a list of held messages, where they can be accepted,
|
|
||||||
rejected or dropped. Spam should be dropped, that's clear. Emails with
|
|
||||||
huge attachments (e.g. screenshots) should be rejected, which gives
|
|
||||||
you an opportunity to explain the reason (in case of large
|
|
||||||
attachments, something like "Please re-send without attachments, offer
|
|
||||||
the files through some other mechanism please: Our emails are
|
|
||||||
distributed to hundreds of readers, and sending the files to everybody
|
|
||||||
is inconsiderate of traffic and storage constraints.")
|
|
||||||
|
|
||||||
Legit emails (often simple requests of the form "is this or that
|
|
||||||
supported") can be accepted, which means they'll be sent out.
|
|
||||||
|
|
||||||
If you notice recurring spam sources (e.g. marketers) you can put them
|
|
||||||
on the [global ban list] to filter them out across all lists. It takes
|
|
||||||
entries in regular expression format.

# Coverity Scan for open source firmware
|
|
||||||
|
|
||||||
## What’s Coverity and Coverity Scan?
|
|
||||||
|
|
||||||
Coverity is a static analysis tool. It hooks into the build process
|
|
||||||
and in addition to the compiler creating object files, Coverity collects
|
|
||||||
information about the code. That data is then processed in a separate pass
|
|
||||||
to identify common programming errors, like out of bounds accesses in C.
|
|
||||||
|
|
||||||
Coverity Scan is an online service for Open Source projects providing this
|
|
||||||
analysis for free. The analysis pass is done on their servers and issues
|
|
||||||
can be handled in their [web UI](https://scan.coverity.com/).
|
|
||||||
|
|
||||||
The Scan service has some quotas based on code size to avoid overloading
|
|
||||||
the system, but even at one build per week, that’s usually good enough
|
|
||||||
because the identified issues still need to be triaged and fixed or they
|
|
||||||
will simply be re-identified next week.
|
|
||||||
|
|
||||||
### Triage?
|
|
||||||
|
|
||||||
The Web UI looks a bit like an issue tracker, even if it’s not a very
|
|
||||||
good one. It’s possible to mark identified issues as valid or invalid,
|
|
||||||
and annotate them with metadata which CLs fix them. The latter isn’t
|
|
||||||
strictly necessary because Coverity Scan simply marks issues it can’t
|
|
||||||
find anymore as fixed, but at times it helped identify issues that made
|
|
||||||
a comeback.
|
|
||||||
|
|
||||||
### Alternatives
|
|
||||||
|
|
||||||
There’s also clang’s scan-build, which is fully open-source, and
|
|
||||||
finds different issues. As such, it’s less of an alternative and more
|
|
||||||
of a complement.
|
|
||||||
|
|
||||||
There’s a regular run of that for coreboot but not for the other projects
|
|
||||||
hosted at coreboot.org.
|
|
||||||
|
|
||||||
One downside is that it emits a bunch of HTML to report on issues,
|
|
||||||
but there’s no interactivity (e.g. marking issues solved), no way
|
|
||||||
to merge multiple builds (e.g. multiple board builds of a single tree)
|
|
||||||
or a simple way to extract burndown charts and the like from that.
|
|
||||||
|
|
||||||
#### Looking for a project?
|
|
||||||
|
|
||||||
On the upside, it can emit the data in a machine readable format, so if
|
|
||||||
anybody needs a project, a scan-build web-frontend like Coverity Scan would
|
|
||||||
be feasible without having to go through scan-build’s guts, just by parsing
|
|
||||||
text files - plus all the stateful and web parts to build on top.
|
|
||||||
|
|
||||||
## Logging into Coverity Scan
|
|
||||||
|
|
||||||
Coverity Scan needs an account. It supports its own accounts and GitHub
|
|
||||||
OAuth.
|
|
||||||
|
|
||||||
Access to the dashboards needs approval: Request and you shall receive.
|
|
||||||
|
|
||||||
## coreboot & friends and Coverity Scan
|
|
||||||
|
|
||||||
coreboot, flashrom, Chromium EC and other projects of that family have
|
|
||||||
been made Coverity aware, that is, their build systems support building
|
|
||||||
with a custom compiler configuration passed in “just right” to enable
|
|
||||||
Coverity to add its hooks.
|
|
||||||
|
|
||||||
The public coreboot CI system at
|
|
||||||
[https://qa.coreboot.org/](https://qa.coreboot.org/) regularly does
|
|
||||||
builds with Coverity and sends them off to Coverity Scan.
|
|
||||||
|
|
||||||
Specifically, it covers:
|
|
||||||
|
|
||||||
* Chromium EC: [Coverity Scan site][crECCoverity] ([build job][crECBuildJob])
|
|
||||||
* coreboot: [Coverity Scan site][corebootCoverity] ([build job][corebootBuildJob]), [scan-build output][corebootScanBuild] ([build job][corebootScanBuildJob])
|
|
||||||

|
|
||||||
|
|
||||||
Some projects (e.g. Chromium EC) build a different subset of boards on
|
|
||||||
each run, ensuring that everything is analyzed eventually. The downside
|
|
||||||
is that coverity issues pop up and disappear somewhat randomly as they
|
|
||||||
are discovered and go unnoticed in a later build.
|
|
||||||
|
|
||||||
More projects that are hosted on review.coreboot.org (potentially as a
|
|
||||||
mirror, like vboot and EC) could be served through that pipeline. Reach
|
|
||||||
out to {stepan,patrick,martin}@coreboot.org.

# Accounts on coreboot.org
|
|
||||||
|
|
||||||
There are a number of places where you can benefit from creating an account
|
|
||||||
in our community. Since there is no single sign-on system in place (at this
|
|
||||||
time), they come with their own setup routines.
|
|
||||||
|
|
||||||
## Gerrit code review
|
|
||||||
We exchange and review patches to the code using our [Gerrit code review
|
|
||||||
system](https://review.coreboot.org).
|
|
||||||
|
|
||||||
It allows logging in with a Google or GitHub account using OAuth2 as well
|
|
||||||
as with any OpenID provider that you may already use.
|
|
||||||
|
|
||||||
On the [settings screen](https://review.coreboot.org/settings) you can register
|
|
||||||
all your email addresses you intend to use in the context of coreboot
|
|
||||||
development so that commits with your email address in them are associated with
|
|
||||||
you properly.

### https push access
|
|
||||||
When using the https URLs to git repositories, you can push with the "HTTP
|
|
||||||
Credentials" you can have Gerrit generate for you on that page. By default,
|
|
||||||
git uses `$HOME/.netrc` for http authentication data, so add a line there
|
|
||||||
stating:
|
|
||||||
|
|
||||||
machine review.coreboot.org login $your-user-name password $your-password
|
|
||||||
|
|
||||||
### Gerrit user avatar
|
|
||||||
To setup an avatar to show in Gerrit, clone the avatars repository at
|
|
||||||
https://review.coreboot.org/gerrit-avatars.git and add a file named
|
|
||||||
$your-user-ID.jpg (the user ID is a number shown on the [settings screen](https://review.coreboot.org/settings)).
|
|
||||||
The image must be provided in JPEG format, must be square and have at most 50000
|
|
||||||
bytes.
|
|
||||||
|
|
||||||
After you push for review, the system will automatically verify your change
|
|
||||||
and, if adhering to these constraints, approve it. You can then immediately
|
|
||||||
submit it.
|
|
||||||
|
|
||||||
## Issue tracker
|
|
||||||
We have an [issue tracker](https://ticket.coreboot.org) that is used for
|
|
||||||
coreboot and related code, such as libpayload, as well as for the project's
|
|
||||||
infrastructure.

# Acer G43T-AM3
|
|
||||||
|
|
||||||
The Acer G43T-AM3 is a microATX-sized desktop board. It was used for the
|
|
||||||
Acer models Aspire M3800, Aspire M5800 and possibly more.
|
|
||||||
|
|
||||||
## Technology
|
|
||||||
|
|
||||||

| Southbridge | Intel ICH10R (called i82801jx in coreboot code) |
|
|
||||||
+------------------+--------------------------------------------------+
|
|
||||||
| CPU socket | LGA 775 |
|
|
||||||
+------------------+--------------------------------------------------+
|
|
||||||
| RAM | 4 x DDR3-1066 |
|

|
|
||||||
+------------------+--------------------------------------------------+
|
|
||||||
```
|
|
||||||
|
|
||||||
There is no serial port. Serial console output is possible by soldering
|
|
||||||
to a point at the corresponding Super I/O pin and patching the
|
|
||||||
mainboard-specific code accordingly.
|
|
||||||
|
|
||||||
## Status
|
|
||||||
|
|
||||||
### Working
|
|
||||||
|
|
||||||
Tests were done with SeaBIOS 1.14.0 and slackware64-live from 2019-07-12
|
|
||||||
(linux-4.19.50).
|
|
||||||
|
|
||||||
+ Intel Core 2 processors at up to FSB 1333
|
|
||||||
+ All four DIMM slots at 1066 MHz (tested 2x2GB + 2x4GB)
|
|
||||||
+ Integrated graphics (libgfxinit)
|
|
||||||
+ HDMI and VGA ports
|
|
||||||
+ Both PCI slots
|
|
||||||
+ Both PCI-e slots
|
|
||||||
+ USB (8 internal, 4 external)
|
|
||||||
+ All six SATA ports
|
|
||||||
+ Onboard Ethernet
|
|
||||||
+ Onboard sound card with output on the rear stereo connector
|
|
||||||
+ PS/2 mouse and keyboard
|
|
||||||
+ With SeaBIOS, use CONFIG_SEABIOS_PS2_TIMEOUT, tested: 500
|
|
||||||
+ With FILO it works without further settings
|
|
||||||
+ Temperature readings from the Super I/O (including the CPU temperature
|
|
||||||
via PECI)
|
|
||||||
+ Super I/O EC automatic fan control
|
|
||||||
+ S3 suspend/resume
|
|
||||||
+ Poweroff
|
|
||||||
|
|
||||||
### Not working
|
|
||||||
|
|
||||||
+ DDR3 memory with 512Mx8 chips (G43 limitation)
|
|
||||||
+ 4x4GB of DDR3 memory (works, but showed a single bit error within one
|
|
||||||
pass of Memtest86+ 5.01)
|
|
||||||
+ Super I/O voltage reading conversions
|
|
||||||
|
|
||||||
### Untested

|
|
||||||
```
|
|
||||||
|
|
||||||
The flash is divided into the following regions, as obtained with
|
|
||||||
`ifdtool -f rom.layout backup.rom`:
|
|
||||||
```
|
|
||||||
00000000:00001fff fd
|
|
||||||
00100000:001fffff bios
|
|
||||||
00006000:000fffff me
|
|
||||||
00002000:00005fff gbe
|
|
||||||
```
|
|
||||||
|
|
||||||
In general, flashing is possible internally and from an external header. It
|
|
||||||
might be necessary to specify the chip type; `MX25L1605D/MX25L1608D/MX25L1673E`
|
|
||||||
is the correct one, not `MX25L1605`.
|
|
||||||
|
|
||||||
### Internal flashing
|
|
||||||
|
|
||||||
Internal access to the flash chip is unrestricted. When installing coreboot,
|
|
||||||
only the BIOS region should be updated by passing the `--ifd` and `-i bios`
|
|
||||||
parameters to flashrom. A full backup is advisable.
|
|
||||||
|
|
||||||
Here is an example:
|
|
||||||
|
|
||||||
```
|
|
||||||
$ sudo flashrom \
|
|
||||||
-p internal \
|
|
||||||
-c "MX25L1605D/MX25L1608D/MX25L1673E" \
|
|
||||||
-r backup.rom
|
|
||||||
$ sudo flashrom \
|
|
||||||
-p internal \
|
|
||||||
-c "MX25L1605D/MX25L1608D/MX25L1673E" \
|
|
||||||
--ifd -i bios \
|
|
||||||
-w coreboot.rom
|
|
||||||
```
|
|
||||||
|
|
||||||
```{eval-rst}
|
|
||||||
In addition to the information here, please see the
|
|
||||||
:doc:`../../tutorial/flashing_firmware/index`.
|
|
||||||
```
|
|
||||||
|
|
||||||
### External flashing
|
|
||||||
|
|
||||||
The SPI flash chip on this board can be flashed externally through the
|
|
||||||
SPI_ROM1 header while the board is off and disconnected from power. There
|
|
||||||
seems to be a diode that prevents the external programmer from powering the
|
|
||||||
whole board.
|
|
||||||
|
|
||||||
The signal assignment on the header is identical to the pinout of the flash
|
|
||||||
chip. The pinout diagram below is valid when the PCI slots are on the left
|
|
||||||
and the CPU is on the right. Note that HOLD# and WP# must be pulled high
|
|
||||||
(to VCC) to be able to flash the chip.
|
|
||||||
|
|
||||||
+---+---+
|
|
||||||
SPI_CSn <- | x | x | -> VCC
|
|
||||||
+---+---+
|
|
||||||
SPI_MISO <- | x | x | -> HOLDn
|
|
||||||
+---+---+
|
|
||||||
WPn <- | x | x | -> SPI_CLK
|
|
||||||
+---+---+
|
|
||||||
GND <- | x | x | -> SPI_MOSI
|
|
||||||
+---+---+
|
|
||||||
|
|
||||||
## Intel Management Engine
|
|
||||||
|
|
||||||
The Intel Management Engine (ME) can be disabled by setting the ME_DISABLE
|
|
||||||
jumper on the board. It pulls GPIO33 on the ICH10 low, causing the "Flash
|
|
||||||
Descriptor Security Override Strap" to be set. This disables the ME and also
|
|
||||||
disables any read/write restrictions to the flash chip that may be set in the
|
|
||||||
Intel Flash Descriptor (IFD) (none on this board). Note that changing this
|
|
||||||
jumper only comes into effect when starting the board from a shutdown or
|
|
||||||
suspend state, not during normal operation.
|
|
||||||
|
|
||||||
To completely remove the ME blob from the flash image and to decrease the size
|
|
||||||
of the ME region, thus increasing the size of the BIOS region, `me_cleaner` can
|
|
||||||
be used with the `-t`, `-r` and `-S` options.
|
|
||||||
|
|
||||||
## Fan control
|
|
||||||
|
|
||||||
There are two fan connectors that can be controlled individually. CPU_FAN
|
|
||||||
can only control a fan by a PWM signal and SYS_FAN only by voltage. See
|
|
||||||
the mainboard's `devicetree.cb` file for how coreboot configures the Super
|
|
||||||
I/O to control the fans.
|
|
||||||
|
|
||||||
## Variants
|
|
||||||
|
|
||||||
Various similar mainboards exist, like the Acer Q45T-AM. During a discussion
|
|
||||||
in #coreboot on IRC, ECS was suspected to be the original designer of this
|
|
||||||
series of mainboards. They have similar models such as the ECS G43T-WM.

|

The flash is divided into the following regions, as obtained with
|
|
||||||
`ifdtool -f rom.layout backup.rom`:
|
|
||||||
```
|
|
||||||
00000000:00000fff fd
|
|
||||||
00200000:007fffff bios
|
|
||||||
00001000:001fffff me
|
|
||||||
```
|
|
||||||
|
|
||||||
### Internal programming
|
|
||||||
|
|
||||||
The main SPI flash can be accessed using flashrom. By default, only
|
|
||||||
the BIOS region of the flash is writable. If you wish to change any
|
|
||||||
other region (Management Engine or flash descriptor), then an external
|
|
||||||
programmer is required.
|
|
||||||
|
|
||||||
The following command may be used to flash coreboot:
|
|
||||||
|
|
||||||
```
|
|
||||||
$ sudo flashrom --noverify-all --ifd -i bios -p internal -w coreboot.rom
|
|
||||||
```
|
|
||||||
|
|
||||||
The use of `--noverify-all` is required since the Management Engine
|
|
||||||
region is not readable even by the host.
|
|
||||||
|
|
||||||
```{eval-rst}
|
|
||||||
In addition to the information here, please see the
|
|
||||||
:doc:`../../tutorial/flashing_firmware/index`.
|
|
||||||
```
|
|
||||||
|
|
||||||
## Hardware monitoring and fan control
|
|
||||||
|
|
||||||
There are two fan headers for the CPU cooler, CPU_FAN1 and CPU_FAN2. They share
|
|
||||||
a single fan tachometer input on the Super I/O while some dedicated logic
|
|
||||||
selects which one is allowed to reach it. Two GPIO pins on the Super I/O are
|
|
||||||
used to control that logic. The firmware has to set them; coreboot selects
|
|
||||||
CPU_FAN1 by default, but the user can change that setting if it was built with
|
|
||||||
CONFIG_USE_OPTION_TABLE:
|
|
||||||
|
|
||||||
```
|
|
||||||
$ sudo nvramtool -e cpu_fan_header
|
|
||||||
[..]
|
|
||||||
$ sudo nvramtool -w cpu_fan_header=CPU_FAN2
|
|
||||||
$ sudo nvramtool -w cpu_fan_header=None
|
|
||||||
$ sudo nvramtool -w cpu_fan_header=Both
|
|
||||||
```
|
|
||||||
|
|
||||||
The setting will take effect after a reboot. Selecting and connecting both fan
|
|
||||||
headers is possible but the Super I/O will report wrong fan speeds.
|
|
||||||
|
|
||||||
Currently there is no automatic, OS-independent fan control, but a software
|
|
||||||
like `fancontrol` from the lm-sensors package can be used instead.
|
|
||||||
|
|
||||||
## Serial port header
|
|
||||||
|
|
||||||
Serial port 1, provided by the Super I/O, is exposed on a pin header. The
|
|
||||||
RS-232 signals are assigned to the header so that its pin numbers map directly
|
|
||||||
to the pin numbers of a DE-9 connector. If your serial port doesn't seem to
|
|
||||||
work, check if your bracket expects a different assignment. Also don't try to
|
|
||||||
connect it directly to a device that operates at TTL levels - it would need a
|
|
||||||
level converter like a MAX232.
|
|
||||||
|
|
||||||
Here is a top view of the serial port header found on this board:
|
|
||||||
|
|
||||||
+---+---+
|
|
||||||
N/C | | 9 | RI -> pin 9
|
|
||||||
+---+---+
|
|
||||||
Pin 8 <- CTS | 8 | 7 | RTS -> pin 7
|
|
||||||
+---+---+
|
|
||||||
Pin 6 <- DSR | 6 | 5 | GND -> pin 5
|
|
||||||
+---+---+
|
|
||||||
Pin 4 <- DTR | 4 | 3 | TxD -> pin 3
|
|
||||||
+---+---+
|
|
||||||
Pin 2 <- RxD | 2 | 1 | DCD -> pin 1
|
|
||||||
+---+---+
|
|
||||||
|
|
||||||
## eSATA
|
|
||||||
|
|
||||||
The eSATA port on the rear I/O panel and the internal connector SATA3_A1 share
|
|
||||||
the same controller port on the ASM1061. Attaching an eSATA drive causes a
|
|
||||||
multiplexer chip to disconnect the internal port from the SATA controller and
|
|
||||||
connect the eSATA port instead. This can be seen on GP23 of the Super I/O
|
|
||||||
GPIOs: it is '0' when something is connected to the eSATA port and '1'
|
|
||||||
otherwise.
