ASRock B450M Pro4 + AMD Ryzen 7 1700 + amdgpu

Remarks

Many trials trying to get the suspend/resume working, ever since version 4.0, with zero success up to now.

Finally, the setup/settings detailed below seem to fix it, at least for a single monitor connected via SVGA.

Qubes freshly installed from qubes 4.1.1 iso.

BIOS

BIOS is restricted to 3.50 and below, because of the Summit Ridge series Processor.

Bios settings:

  • Setting 1: Advanced / CPU configuration / SVM mode → enabled
  • Setting 2: Advanced / Onboard Devices configuration / SR-IOV support → enabled
  • Setting 3: Advanced / AMD CBS /NBIO common options / IOMMU —> enabled
  • Setting 4: Advanced / AMD CBS /NBIO common options / PCIe ARI support → Auto (removes some corrupted pixels which appear on the top panel.

As installed, suspend/resume of Qubes causes hard lockup of display and sometimes reboot. lsmod shows both radeon and amdgpu in use.

Modules/parameters

Create /etc/modprobe.d/radeon-amdgpu.conf and add:

  blacklist radeon
  options amdgpu si_support=1
  options amdgpu cik_support=1

Update initrd (I think this is necessary):

  sudo dracut --force

Up to now, changes mean we can boot with only amdgpu module, and no radeon.

Command line parameters

Also, edit /etc/default/grub, and add “mem_sleep_default=deep” to the end of GRUB_CMDLINE_LINUX, and update grub. For me, the command was :

sudo grub2-mkconfig -o /boot/efi/EFI/qubes/grub.cfg

(Not sure that this command line option is necessary.)

xorg amdgpu driver

Install the amdgpu xorg driver:

  qubes-dom0-update xorg-x11-drv-amdgpu

This is version 22.0.0-2.fc32.

Driver option: create /etc/X11/xorg.conf.d/50-amdgpu.conf :

  Section "Device"
    	Identifier "card0"
    	Driver "amdgpu"
    	Option "AccelMethod" "none"
  EndSection

Not sure what that does - the ‘amdgpu’ man page says it only turns off 2D acceleration. glxgears looks OK, and the option seems to be necessary for resume to work.

Now suspend/resume seems to work. At least, over 100 cycles without problems…

  • Tested/working: Network, SATA, USB…
  • Not tested: audio, non-svga video outputs, instrumentation/sensors, fTPM.
  • Am crossing fingers!
