Asrock E350M1: Display regression in Linux

[HacKurx]

Good morning, everyone,

I hadn't updated my coreboot version for a long time on my Asrock
E350M1 card because of lack of time and because this one was on a very
stable version. While trying to test the current 4.12 version, I
encountered problems in Debian 10.

Indeed, there is a bad graphical detection, the resolution of my hdmi
output went from 1360x768 to 720x400 pixels.
Xorg indicates that the drm device cannot be opened :
(EE) open /dev/dri/card0: No such file or directory

I once had a Oops kernel message:
https://pastebin.com/uZLZyYrq

My coreboot graphical configuration is as follows:
CONFIG_VGA_BIOS_ID="1002,9802"
CONFIG_ONBOARD_VGA_IS_PRIMARY=y
CONFIG_VGA_BIOS=y
CONFIG_VGA_BIOS_FILE="vgabios.bin"

I manage to restore normal working in coreboot 4.12-git by removing the commits:
a5c2ac6256d0dae112b24c422d1270919acb6321 "x86/acpi: Add VFCT table"
6f978cfd1ab6a57e5729e19bed3df7702c4f09cb "x86/acpi: Use initialized
VBIOS in VFCT table"

Thank you. Best regards,

Loic

Dear HacKurx,

Thank you for the report.

What coreboot version did you use before?

For the future, please attach the logs to the message, so people can 
read it offline.

I paste the error below.

I cannot remember seeing this on my board [1], but I am only using the 
VGA adapter (shouldn’t matter).

[    1.552912] [drm] Found smc ucode version: 0x00010601

These commits have been present since coreboot 4.6, and I have not seen 
this. It just provides the VGA Optiom ROM/Video BIOS to the graphics 
driver via ACPI.

Do you have the AMD graphics firmware files installed under 
`/lib/firmware/radeon`?

Please attach your coreboot configuration (`defconfig` generated by 
`make savedefconfig`), and the output of `build/cbfstool 
build/coreboot.rom print`.

Anyway, I guess it could be a problem in Linux 4.19.118. Could you 
please try a recent Linux kernel from the Debian backports repository, 
or another way? If that problem is fixed in newer versions, the Linux 
stable folks and Debian Linux kernel folks should backport that commit.

Kind regards,

Paul

Before, coreboot-4.2-20160128 with SeaBIOS-1.9.0

But because of the problem, I've been testing coreboot-4.5-20170204
(commit 8a06cc7ec8 util/ifdtool: Fix ICH Gbe unlock) with
SeaBIOS-1.13.0-20200603 which works well (it's the commit before the
one I had to reverse).

In linux :
drivers/gpu/drm/radeon/sumo_dpm.c:    DRM_INFO("Found smc ucode
version: 0x%08x\n", pi->fw_version);

I just change the coreboot version without changing my OS. As soon as
I overrun a version with this commit, I get a display problem.

Yes. We can even see the loading the dmesg:

I'm willing to redo a test with a newer kernel, but I had the same
problem with Ubuntu 20.04 LTS (Linux 5.4.0-29-generic).

Thanks.

Nothing to do, debian can't boot properly with kernels 5.4 and 5.7 [1]. I
can only reach lightdm using nomodeset (but i have a bad graphic
resolution).
I tried with your kernel parameters and VGA but it doesn't change anything.

I compared with the original bios, there was no VFCT table:

Let’s try to find the error in the Linux driver code.

Please install the the debug symbols with

apt install linux-image-<our version>-dbg

and run the script from the Linux tree.

scripts/faddr2line vmlinux sumo_dpm_enable+0x2ed/0x510

I believe, you can also use `scripts/decodecode` feed it the Linux 
messages. It will parse the `Code:` line.

[…]

Kind regards,

Paul

Hello again, Paul,

Indeed the problem comes indeed VGA Option ROM. We use different versions.

ASRock had modified several times the detection function of the VGA
cards and an intermediate version is not compatible with the 2 commits
that I had designated.
When comparing printable strings from different versions of vgabios, I
found the following differences.

pci1002,9802.rom from the Wiki use: IBMM
intermediate version incompatible with VFCT use: IBM
latest vgabios (version ASRock 2.10) use: IBM0

Problem solved. Thank you for your time.

Best Regards,

Loic
