Kernel 5.13.4 (both arch and zen) disable VAAPI on RX6700XT

Hello everybody.

Since recent kernel update 5.13.4 I noticed that VAAPI stopped working.

Here is my output on kernel 5.12.15

```
$ uname -a
Linux home 5.12.15-zen1-1-zen #1 ZEN SMP PREEMPT Wed, 07 Jul 2021 23:35:33 +0000 x86_64 GNU/Linux

$ vainfo     
vainfo: VA-API version: 1.12 (libva 2.12.0)
vainfo: Driver version: Mesa Gallium driver 21.1.5 for AMD Radeon RX 6700 XT (NAVY_FLOUNDER, DRM 3.40.0, 5.12.15-zen1-1-zen, LLVM 12.0.1)
vainfo: Supported profile and entrypoints

      VAProfileMPEG2Main              : VAEntrypointVLD
      VAProfileVC1Simple              : VAEntrypointVLD
      VAProfileVC1Main                : VAEntrypointVLD
      VAProfileVC1Advanced            : VAEntrypointVLD
      VAProfileH264ConstrainedBaseline: VAEntrypointVLD
      VAProfileH264ConstrainedBaseline: VAEntrypointEncSlice
      VAProfileH264Main               : VAEntrypointVLD
      VAProfileH264Main               : VAEntrypointEncSlice
      VAProfileH264High               : VAEntrypointVLD
      VAProfileH264High               : VAEntrypointEncSlice
      VAProfileHEVCMain               : VAEntrypointVLD
      VAProfileHEVCMain               : VAEntrypointEncSlice
      VAProfileHEVCMain10             : VAEntrypointVLD
      VAProfileHEVCMain10             : VAEntrypointEncSlice
      VAProfileJPEGBaseline           : VAEntrypointVLD
      VAProfileVP9Profile0            : VAEntrypointVLD
      VAProfileVP9Profile2            : VAEntrypointVLD
      VAProfileNone                   : VAEntrypointVideoProc
```

This is what I see after kernel update

```
vainfo: VA-API version: 1.12 (libva 2.12.0)
vainfo: Driver version: Mesa Gallium driver 21.1.5 for AMD Radeon RX 6700 XT (NAVY_FLOUNDER, DRM 3.41.0, 5.13.4-arch1-1, LLVM 12.0.1)
vainfo: Supported profile and entrypoints
      VAProfileMPEG2Simple            : VAEntrypointVLD
      VAProfileMPEG2Main              : VAEntrypointVLD
      VAProfileNone                   : VAEntrypointVideoProc
```

Does anyone have any ideas on why this is happening?

Found similar cases on reddit:

1. https://www.reddit.com/r/archlinux/comm … ernel_513/
2. https://www.reddit.com/r/linuxquestions … ration_on/

Seems like a bug

I suspect this is related to a huge number of amdgpu regressions in 5.13 (e.g. https://bbs.archlinux.org/viewtopic.php?id=267874). 5.14rc3 seems better, which hopefully means backports for 5.13.6.

5.13.7 still doesn't work... I see the bug has been reported: https://bugs.archlinux.org/task/71627 so waiting for resolution.

The fix has to come from upstream.  That is why jonathon asked if the issue was still present in linux-mainline.  If it is not fixed in 5.14-rc4 then you should report it to the amdgpu developers https://gitlab.freedesktop.org/drm/amd/-/issues
