Vulkan support with AMD Radeon R7 M270

Hi all, I'm trying to get the discrete part of the hybrid graphics (Intel 5500 and Radeon R7 M270) on an old-ish laptop (Dell Inspiron 15-7548) to work on Arch. Vulkan works fine on the Intel integrated graphics, and games run with acceptable performance.

With the default radeon driver, the card is recognised and shows in DRI_PRIME=1 glxinfo, but is incompatible with Vulkan.

From reading around, it appears that for Vulkan I need to use the amdgpu module rather than radeon and enable Southern Islands support, which I've done, and lspci -k shows that the correct module is being used:

08:00.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] Opal XT [Radeon R7 M265/M365X/M465]
	Subsystem: Dell Device 066f
	Kernel driver in use: amdgpu
	Kernel modules: radeon, amdgpu

I've installed vulkan-radeon. But the AMD card doesn't show up in vulkaninfo, only the Intel one:

GPU0:
	apiVersion         = 4206799 (1.3.207)
	driverVersion      = 92274787 (0x5800063)
	vendorID           = 0x8086
	deviceID           = 0x1616
	deviceType         = PHYSICAL_DEVICE_TYPE_INTEGRATED_GPU
	deviceName         = Intel(R) HD Graphics 5500 (BDW GT2)
	driverID           = DRIVER_ID_INTEL_OPEN_SOURCE_MESA
	driverName         = Intel open-source Mesa driver
	driverInfo         = Mesa 22.1.0-devel (git-c36f3f2db8)
	conformanceVersion = 1.3.0.0
	deviceUUID         = ac4fb3eb-5a7e-0746-aa75-ea5ffa086705
	driverUUID         = 6bb939f3-be67-e4ef-5d5c-fe93310bf57f
GPU1:
	apiVersion         = 4202703 (1.2.207)
	driverVersion      = 1 (0x0001)
	vendorID           = 0x10005
	deviceID           = 0x0000
	deviceType         = PHYSICAL_DEVICE_TYPE_CPU
	deviceName         = llvmpipe (LLVM 13.0.1, 256 bits)
	driverID           = DRIVER_ID_MESA_LLVMPIPE
	driverName         = llvmpipe
	driverInfo         = Mesa 22.1.0-devel (git-c36f3f2db8) (LLVM 13.0.1)
	conformanceVersion = 0.0.0.0
	deviceUUID         = 6d657361-3232-2e31-2e30-2d6465766500
	driverUUID         = 6c6c766d-7069-7065-5555-494400000000

The AMD card also no longer shows up in DRI_PRIME=1 glxinfo with the amdgpu module loaded, so it appears that the problem isn't with Vulkan but with the module not loading properly in the first place.

I've had a look at dmesg to see if there's any relevant output:

I've tried Googling these "UVD Firmware validate fail" and "resume of IP block" messages, and I've found a few results but they all seem to be related to resuming from hibernate, e.g. https://bugs.launchpad.net/ubuntu/+sour … ug/1953249. I've never used hibernate on this machine, and moreover, that issue seems to be fixed now in linux-firmware.

Any ideas?

Re: Vulkan support with AMD Radeon R7 M270

Hmm.. Is this card a amd r7 200 series southern islands card? the amdgpu driver works much better for me.
try having a look at arch wiki here https://wiki.archlinux.org/title/AMDGPU … mmand_line

Yep, it's Southern Islands. As described in my original post, I've already set up amdgpu and enabled SI support, and the amdgpu module is now loading correctly but does not seem to be working.

Re: Vulkan support with AMD Radeon R7 M270

Which vulkan driver are you trying to use? amdvlk won't work, remove it and install radeon-vulkan instead, if that's where it's hanging.

Sorry for the delay in reply, I had given up hope with this! I'm definitely using vulkan-radeon from mesa if that's what you mean (although I did try amdvlk too).

I also tried with vulkan-radeon from mesa-git, but no luck with that.

Re: Vulkan support with AMD Radeon R7 M270

Hi there, wondering whether or not the AMD GPU is being switched off automatically if amdgpu has more advanced power saving functionality than standard radeon. Do you think you could

sudo cat /sys/kernel/debug/vgaswitcheroo/switch

and post the output? Hopefully this debug file exists for you, in which case we can use it to see if the AMD video card is being fully powered off.
