Did you remember to add modconf to the HOOKS array in /etc/mkinitcpio.conf and regenerate the initramfs?

mohammadsm · 2022-08-21 20:58:55

yse
HOOKS=(modconf base udev autodetect block filesystems keyboard fsck)
and then run
sudo mkinitcpio -P
and reboot system
but kernel dont use amdgpu

HOOKS=(modconf base udev autodetect block filesystems keyboard fsck)

The order of hooks is important, try putting modconf between autodetect & block as shown in the example in /etc/mkinitcpio.conf
(if that doesn't help, try after filesystems)

remove radeon from the MODULES= line in mkinitcpio.conf , regenerate and reboot.

If that doesn't help, post dmesg and/or journal from last boot (run both with root-rights).

See https://wiki.archlinux.org/title/List_o … n_services for methods to upload large text files.

the amdgpu kernel module is loaded, but it seems the parameters are still not used.

Let's pass them directly to the kernel : append amdgpu.si_support=1 amdgpu.cik_support=1 to your boot command line, reboot.

This will show if the parameters are applied:

cat /sys/module/amdgpu/parameters/{si,cik}_support

And I think you should only enable either Southern Islands ("si") or Sea Islands ("cik") amdgpu support for the card, not both — dmesg may indicate which is appropriate, otherwise consult the interweb.

When reading the hd 7000 series articles on wikipedia in english and german I get the impression that this gpu is pre-GCN.

If true:
- amdgpu does not support this card, so loading it leeds to nothing
- the si an cik related parameters won't help
- the radeon module is likely the right choice

{
% cat /sys/module/amdgpu/parameters/{si,cik}_support
1
1
}
this is output
suport to items
what should i do
use one of them or use both

To me this reads like pre-GCN but for some reason sharing a vid/pid with something newer which does lead to amdgpu being loaded while it doesn't actually support it.

What the windows driver does is irrelevant, you do have the radeon driver here which is apparently working correctly. You can "play" with that as well but it will lack Vulkan which is probably what you are looking for, and likely not going to get.

the firmware loaded is indeed for caicos which does confirm this is a terascale 2 chipset that can't work with amdgpu.

I think V1del is right.
