wifi This reverts commit5e6fd360de. On nereid, the SSDT entry for the PCIe wifi device is missing, causing wake-on-WLAN not to work since the _PRW is missing. It seems like when commit5e6fd360dechanged the SSDT generation logic for CNVi and PCIe wifi, it broke the PCIe case. `wifi_pcie_ops` are never assigned to any device, so `parent && parent->ops == &wifi_pcie_ops` always returns false, and the `wifi_cnvi_ops` are used even for PCIe devices. Undo the changes in that CL. This allows both the CNVi and PCIe cases to work. That CL was meant to fix an issue with the CNVi _PRW containing garbage, but I can't reproduce this when the change is undone. It was also meant to fix the following error on CNVi devices, but I don't see any errors with this change: [ERROR] NONE missing set_resources BUB=b:233325709 TEST=On both nivviks (CNVi) and nereid (PCIe), check that the SSDT contains the correct wifi device entries (below), including a _PRW containing the correct GPE, and check that wake-on-WLAN works. nivviks: ``` Scope (\_SB.PCI0.CNVW) { Name (_PRW, Package (0x02) // _PRW: Power Resources for Wake { 0x6D, 0x03 }) Method (_DSM, 4, Serialized) // _DSM: Device-Specific Method { <snip> } } ``` nereid: ``` Device (\_SB.PCI0.RP01.WF00) { Name (_UID, 0x923ACF1C) // _UID: Unique ID Name (_DDN, "WIFI Device") // _DDN: DOS Device Name Name (_ADR, 0x0000000000000000) // _ADR: Address } Scope (\_SB.PCI0.RP01.WF00) { Name (_PRW, Package (0x02) // _PRW: Power Resources for Wake { 0x23, 0x03 }) Method (_DSM, 4, Serialized) // _DSM: Device-Specific Method { <snip> } } ``` Fixes:5e6fd360de("drivers/wifi/generic: Fix properties in generic-under-PCI device case") Change-Id: I100c5ee3842997c50444e5ce68d583834ed3a8ad Signed-off-by: Reka Norman <rekanorman@chromium.org> Reviewed-on: https://review.coreboot.org/c/coreboot/+/66063 Reviewed-by: Eric Lai <eric_lai@quanta.corp-partner.google.com> Reviewed-by: Kangheui Won <khwon@chromium.org> Reviewed-by: Tim Wawrzynczak <twawrzynczak@chromium.org> Tested-by: build bot (Jenkins) <no-reply@coreboot.org>
coreboot README
coreboot is a Free Software project aimed at replacing the proprietary BIOS (firmware) found in most computers. coreboot performs a little bit of hardware initialization and then executes additional boot logic, called a payload.
With the separation of hardware initialization and later boot logic, coreboot can scale from specialized applications that run directly firmware, run operating systems in flash, load custom bootloaders, or implement firmware standards, like PC BIOS services or UEFI. This allows for systems to only include the features necessary in the target application, reducing the amount of code and flash space required.
coreboot was formerly known as LinuxBIOS.
Payloads
After the basic initialization of the hardware has been performed, any desired "payload" can be started by coreboot.
See https://www.coreboot.org/Payloads for a list of supported payloads.
Supported Hardware
coreboot supports a wide range of chipsets, devices, and mainboards.
For details please consult:
Build Requirements
- make
- gcc / g++
Because Linux distribution compilers tend to use lots of patches. coreboot
does lots of "unusual" things in its build system, some of which break due
to those patches, sometimes by gcc aborting, sometimes - and that's worse -
by generating broken object code.
Two options: use our toolchain (eg. make crosstools-i386) or enable the
ANY_TOOLCHAINKconfig option if you're feeling lucky (no support in this case). - iasl (for targets with ACPI support)
- pkg-config
- libssl-dev (openssl)
Optional:
- gdb (for better debugging facilities on some targets)
- ncurses (for
make menuconfigandmake nconfig) - flex and bison (for regenerating parsers)
Building coreboot
Please consult https://www.coreboot.org/Build_HOWTO for details.
Testing coreboot Without Modifying Your Hardware
If you want to test coreboot without any risks before you really decide to use it on your hardware, you can use the QEMU system emulator to run coreboot virtually in QEMU.
Please see https://www.coreboot.org/QEMU for details.
