[ Impact ]

AMD GPU not functional on Focal with HWE kernel.

[ Test Case ]

See original description below.

[ Fix ]

Cherry-pick relevant commit from upstream linux-firmware.

[ Where Problems Could Occur ]

Broken graphics with AMD GPUs.

[ Original Description ]

Release: up-to-date Focal LTS (20.04.3)
Package-version: linux-firmware 1.187.20
Hardware model: [AMD/ATI] Chelsea LP [Radeon HD 7730M]

With the latest kernel upgrade (5.4 --> 5.11, if I recall correctly), my laptop's discrete graphics stopped working. Looking at the logs, I found these messages:

-- snippet --

In fact, file '/lib/firmware/amdgpu/verde_uvd.bin' was missing. Running '$ dpkg -L linux-firmware | sort' gives this:

-- snippet --
/lib/firmware/amdgpu/vegam_uvd.bin
/lib/firmware/amdgpu/vegam_vce.bin
/lib/firmware/amdgpu/verde_ce.bin

/lib/firmware/amdgpu/verde_smc.bin
/lib/firmware/amdgpu/yellow_carp_asd.bin
/lib/firmware/amdgpu/yellow_carp_ce.bin

Copying the file from upstream (https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git/tree/amdgpu/verde_uvd.bin) didn't work on my system, probably because I use UEFI and the module wasn't signed (error below):

-- snippet --

I can confirm that reverting kernel driver to 'radeonsi' makes the device usable again, but at the expense of Vulkan APIs (not supported by this driver).

Could you, please, fix this?
