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
