Description:
Arch Linux recently shipped linux-firmware 20180119.2a713be-1. This includes UVD Firmware v1.130 for Polaris AMD GPUs (such as my AMD Radeon RX 460) which breaks VDPAU with h265 and some other codecs on older versions of Mesa (causing heavy artifacting and glitching during playback) without a commit that is not in the 17.3.2 in the repos or in the 17.3.3 in testing but could be patched in.

Bug Report about this: https://bugs.freedesktop.org/show_bug.cgi?id=104745
Patch needed: https://cgit.freedesktop.org/mesa/mesa/commit/?id=2ec48039b8aa1f6a5e16f3f12483b88981d0f5d3

Additional info:
* mesa-vdpau 17.3.2-2, 17.3.3-1
* linux-firmware 20180119.2a713be-1 (linux-firmware-20171206.fdee922-1 did not interact with this bug)


Steps to reproduce:
Open MPV with a H265 video file and VDPAU enabled for hardware decoding on an AMD Polaris GPU. Watch the video and heavy video corruption commences.
This task depends upon

Have tested the patch on a copy of 17.3.3 I compiled myself and can confirm it fixes the problem.

According to the bug I filed on freedesktop, the patch is getting picked up for future 17.3.X point releases, for the record.

Please test mesa-17.3.3-2 in testing repo

mesa-17.3.3-2 packages have functioning VDPAU hardware decoding with H265 on the RX 460. Thanks.
