# ASUS A88XM-E
|
||||
|
||||
This page describes how to run coreboot on the [ASUS A88XM-E].
|
||||
|
||||
## Technology
|
||||
|
||||
Both "Trinity" and "Richland" FM2 desktop processing units are working,
|
||||
the CPU architecture in these CPUs/APUs are [Piledriver],
|
||||
and their GPU is [TeraScale 3] (VLIW4-based).
|
||||
|
||||
Kaveri is non-working at the moment (FM2+),
|
||||
the CPU architecture in these CPUs/APUs are [Steamroller],
|
||||
and their GPU is [Sea Islands] (GCN2-based).
|
||||
|
||||
A10 Richland is recommended for the best performance and working IOMMU.

| Type | Value |

| Model | [GD25Q64] |

|
||||

|
||||
| Internal flashing | yes |
|
||||
+---------------------+------------+
|
||||
```
|
||||
|
||||
### Internal programming
|
||||
|
||||
The main SPI flash can be accessed using [flashrom], if the
|
||||
AmdSpiRomProtect modules have been deleted in the factory image previously.
|
||||
|
||||
### External flashing
|
||||
|
||||
Using a PLCC Extractor or any other appropriate tool, carefully remove the
|
||||
DIP-8 BIOS chip from its' socket while avoiding the bent pins, if possible.
|
||||
To flash it, use a [flashrom]-supported USB CH341A programmer - preferably with a
|
||||
green PCB - and double check that it's giving a 3.3V voltage on the socket pins.
|
||||
|
||||
## Integrated graphics
|
||||
|
||||
### Retrieve the VGA optionrom ("Retrieval via Linux kernel" method)
|
||||
|
||||
Make sure a proprietary UEFI is flashed and boot Linux with iomem=relaxed flag.
|
||||
Some Linux drivers (e.g. radeon for AMD) make option ROMs like the video blob
|
||||
available to user space via sysfs. To use that to get the blob you need to
|
||||
enable it first. To that end you need to determine the path within /sys
|
||||
corresponding to your graphics chip. It looks like this:
|
||||
|
||||
# /sys/devices/pci<domain>:<bus>/<domain>:<bus>:<slot>.<function>/rom.
|
||||
|
||||
You can get the respective information with lspci, for example:
|
||||
|
||||
# lspci -tv
|
||||
# -[0000:00]-+-00.0 Advanced Micro Devices, Inc. [AMD] Family 16h Processor Root Complex
|
||||
# +-01.0 Advanced Micro Devices, Inc. [AMD/ATI] Kabini [Radeon HD 8210]
|
||||
# ...
|
||||
|
||||
Here the the needed bits (for the ROM of the Kabini device) are:
|
||||
|
||||
# PCI domain: (almost always) 0000
|
||||
# PCI bus: (also very commonly) 00
|
||||
# PCI slot: 01 (logical slot; different from any physical slots)
|
||||
# PCI function: 0 (a PCI device might have multiple functions... shouldn't matter here)
|
||||
|
||||
To enable reading of the ROM you need to write 1 to the respective file, e.g.:
|
||||
|
||||
# echo 1 > /sys/devices/pci0000:00/0000:00:01.0/rom
|
||||
|
||||
The same file should then contain the video blob and it should be possible to simply copy it, e.g.:
|
||||
|
||||
# cp /sys/devices/pci0000:00/0000:00:01.0/rom vgabios.bin
|
||||
|
||||
romheaders should print reasonable output for this file.
|
||||
|
||||
This version is usable for all the GPUs.

|

|
||||
## Known issues
|
||||
|
||||
- AHCI hot-plug
|
||||
- S3 resume (sometimes)
|
||||
- Windows 7 can't boot because of the incomplete ACPI implementation
|
||||
- XHCI
|
||||
|
||||
### XHCI ports can break after using any of the blobs, restarting the
|
||||
board with factory image makes it work again as fallback.
|
||||
Tested even with/without the Bolton and Hudson blobs.
|
||||
|
||||
## Untested
|
||||
|
||||
- audio over HDMI
|
||||
|
||||
## TODOs
|
||||
|
||||
- one ATOMBIOS module for all the integrated GPUs
|
||||
- manage to work with Kaveri/Godavary (they are using a binaryPI)
|
||||
- IRQ routing is done incorrect way - common problem of fam15h boards
|
||||
|
||||
## Working
|
||||
|
||||
- ACPI
|
||||
- CPU frequency scaling
|
||||
- flashrom under coreboot
|
||||
- Gigabit Ethernet
|
||||
- Hardware monitoring
|
||||
- Integrated graphics
|
||||
- KVM virtualization
|
||||
- Onboard audio
|
||||
- PCI
|
||||
- PCIe
|
||||
- PS/2 keyboard mouse (during payload, bootloader)
|
||||
- SATA
|
||||
- Serial port
|
||||
- SuperIO based fan control
|
||||
- USB (disabling XHCI controller makes to work as fallback USB2.0 ports)
|
||||
- IOMMU
