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

## Technology
|
||||||
|
|
||||||
|
Both "Trinity" and "Richland" desktop processing units are working,
|
||||||
|
the CPU architecture in these CPUs/APUs is [Piledriver],
|
||||||
|
and their GPU is [TeraScale 3] (VLIW4-based).

|

|
### Internal programming
|
||||||
|
|
||||||
|
The main SPI flash can be accessed using [flashrom].
|
||||||
|
UEFI builds that allow flash chip access:
|
||||||
|
> v5016 is untested, but expected to work as well
|
||||||
|
> v5018
|
||||||
|
> v5103
|
||||||
|
> v5104
|
||||||
|
> v5107
|
||||||
|
> v5202
|
||||||
|
> v6002
|
||||||
|
> v6004
|
||||||
|
> v6102
|
||||||
|
> v6402
|
||||||
|
> v6404 (requires downgrading to v6402 to flash coreboot)
|
||||||
|
> v6501 (requires downgrading to v6402 to flash coreboot)
|
||||||
|
> v6502 (requires downgrading to v6402 to flash coreboot)
|
||||||
|
|
||||||
|
Build v6502, v6501 and v6404 do not allow access to the flash chip.
|
||||||
|
Fortunately it is possible to downgrade build v6502, v6501, v6404 to v6402, with EZFlash.
|
||||||
|
Downgrading is done by downloading build v6402 from ASUS' F2A85-M download page
|
||||||
|
and copying it to (the root directory of) a FAT32 formatted USB flash drive.
|
||||||
|
Enter the EFI setup, switch to advanced mode if necessary,
|
||||||
|
open the 'Tool' tab and select "ASUS EZ Flash 2 Utility".
|
||||||
|
|
||||||
|
## Integrated graphics
|
||||||
|
|
||||||
|
### Option 1: Retrieve the VGA optionrom from the vendor EFI binary by running:
|
||||||
|
|
||||||
|
# dd if=/dev/mem of=vgabios.bin bs=1k count=64 skip=768
|
||||||
|
|
||||||
|
### Option 2: Extract from the vendor binary
|
||||||
|
|
||||||
|
Download the BIOS from the Support section at [ASUS F2A85-M].
|
||||||
|
Using MMTool Aptio (versions 4.5.0 and 5.0.0):
|
||||||
|
- Load image, click on 'Extract tab'
|
||||||
|
- Select the 'export path' and 'link present' options
|
||||||
|
- Choose option ROM '1002,9900' and click on 'Extract'
|
||||||
|
|
||||||
|
This version is usable for all the GPUs.
|
||||||
|
> 1002,9901 Trinity (Radeon HD 7660D)
|
||||||
|
> 1002,9904 Trinity (Radeon HD 7560D)
|
||||||
|
> 1002,990c Richland (Radeon HD 8670D)
|
||||||
|
> 1002,990e Richland (Radeon HD 8570D)
|
||||||
|
> 1002,9991 Trinity (Radeon HD 7540D)
|
||||||
|
> 1002,9993 Trinity (Radeon HD 7480D)
|
||||||
|
> 1002,9996 Richland (Radeon HD 8470D)
|
||||||
|
> 1002,9998 Richland (Radeon HD 8370D)
|
||||||
|
> 1002,999d Richland (Radeon HD 8550D)
|
||||||
|
|
||||||
|
## Known issues
|
||||||
|
|
||||||
|
- buggy USB 3.0 controller (works fine as 2.0 port)
|
||||||
|
- reboot, poweroff, S3 suspend/resume (broken since 4.8.1)
|
||||||
|
|
||||||
|
## Known issues (untested because of non-working ACPI sleep)
|
||||||
|
|
||||||
|
- blink in suspend mode (GP43, program LDN7 F8=23 and blink with F9=2 for 1s blinks)
|
||||||
|
- fix immediate resume after suspend (perhaps PCIe STS needs to be cleared)
|
||||||
|
- fix resume with USB3.0 used (perhaps there is a bug in resume.c)
|
||||||
|
|
||||||
|
## Untested
|
||||||
|
|
||||||
|
- audio over HDMI
|
||||||
|
- IOMMU
|
||||||
|
- PS/2 mouse
|
||||||
|
|
||||||
|
## TODOs
|
||||||
|
|
||||||
|
- manage to use one ATOMBIOS for all the integrated GPUs
|
||||||
|
|
||||||
|
## Working
|
||||||
|
|
||||||
|
- ACPI
|
||||||
|
- CPU frequency scaling
|
||||||
|
- flashrom under coreboot
|
||||||
|
- Gigabit Ethernet
|
||||||
|
- Hardware monitor
|
||||||
|
- Integrated graphics
|
||||||
|
- KVM
|
||||||
|
- Onboard audio
|
||||||
|
- PCIe
|
||||||
|
- PS/2 keyboard
|
||||||
|
- SATA
|
||||||
|
- Serial port
|
||||||
|
- SuperIO based fan control
|
||||||
|
- USB (XHCI is buggy)
