[SOLVED] AMD GPU inaccessible after VM Poweroff: Unable to change power state from D3cold to D0,device inaccessible.

[nywst]

I manage to update the value to 'device_specific'.
But my GPU 5600xt is still showing 'not working properly' in win11 vm after reboot.
No error msgs at all in pve, only this:

Refused to change power state from D0 to D3hot

I am done with this GPU passthrough experiment, not worth my time.

Step 9 doesn't work, and I don't understand why it should work, as it uses sysfs.
Error:

# echo 'device_specific' > /sys/bus/pci/devices/0000\:04\:00.0/reset_method
-bash: echo: write error: Invalid argument

My GPU address is 0000:04:00.0 too.

Yes indeed, I've used several ls cat nano and other stuff to view/pass in the command lol, I can't edit the old guide/my reply somehow, I remembered once I had to update it and didn't cuz I can't figure out how to edit

For anyone that ended up here in this post, on Kernel 6.8.12-2 both GRUB and UEFI boot modes support the edit of the file in Step 9. You cannot edit it directly with nano, but you can use:

echo 'device_specific' > /sys/bus/pci/devices/0000\:04\:00.0/reset_method

If you want to automate this, you can use the command 'crontab -e' and add the below line that uses the other suggested command from above:

@reboot sh -c "echo 'device_specific' > /sys/bus/pci/devices/0000\:04\:00.0/reset_method" >/dev/null 2>&1

I tried it with 3 navi cards already and it works great. Actually with UEFI installation I could even put the normal echo command in crontab -e, but with GRUB installation it was requiring the other one to overwrite the file contents on each boot.

Unfortunately that does NOT work for me .
