Phoronix: Updated AMDGPU VCN Firmware Fixes VP9 Decoding Issues

For those that have experienced glitches while playing back VP9 video content using AMD's Video Core Next (VCN) for GPU acceleration, updated firmware should fix those VP9 decode problems...

It does not happen in chromium or mpv without hwdec.

So this is basically saying that chromium doesn't use hardware acceleration for video!

Oh wow, this has been really annoying, but I wasn't looking to the right place, thanks for informing. (and thanks to those who fixed it)

I think my experience on Raven Ridge looks very similar to the description of this bug too. I experienced with force-enable hardware video decode in Firefox but the machine become unstable in Youtube playback. But looks like Raven is not included in this update?

On Arch Linux if you won't add FILES=(/lib/firmware/amdgpu/vcn_4_0_2.bin.zst) to /etc/mkinitcpio.conf followed by a sudo mkinitcpio -P updating the firmware package won't be enough to do the trick.

Does this arrive via "kernel firmware" updates in standard distro update mechnsiams?

e.g. zypper dup for tumbleweed.

Yes. A zypper dup pulls in the latest firmware quite frequently.

And speak of the devil...

I just got the firmware updates in today's dup to the 20240303 snapshot.

I have had the same symptoms for AV1 decoding on youtube even using Radeon RX 6800 XT for more then one year, AMD was so slow to do anything about it

Are you sure? Looks like your are loading KMS hook https://wiki.archlinux.org/title/Ker...arly_KMS_start


Late KMS start

Intel, Nouveau, ATI and AMDGPU drivers already enable KMS automatically for all chipsets, so you need not install it manually.
The proprietary NVIDIA driver supports KMS (since 364.12), which has to be manually enabled.
