dancingmirrors cd91e8f22f hasvk: Remove now unreachable layered clamping. 2026-07-21 22:25:28 +03:00
dancingmirrors 409568b8d4 hasvk: We can use ARYSPC_LOD0 for layered DPB. 2026-07-21 22:25:28 +03:00
dancingmirrors 49447ce96e hasvk: Expose HASVK_DEBUG=video-debug and clean it up. 2026-07-21 22:25:28 +03:00
dancingmirrors c9dcef66aa hasvk: Emit MFX_AVC_WEIGHTOFFSET_STATE for both list 0 and list 1. 
Fixes Haswell corruption with https://files.lynne.ee/testsamples/bbc2.sample.h264.
This is the correct thing to do anyway and only worked on Ivy Bridge by accident.

dancingmirrors 1d4d7c0650 hasvk: Haswell doesn't have the same DMV buffer as earlier generations. 2026-07-21 22:25:27 +03:00
dancingmirrors 564cead081 hasvk: Without a QPitch override gen7 can't reliably handle layered DPB. 
Just accept corruption and avoid intermittent hangs when not tile aligned.
Breaks: dEQP-VK.video.decode.h264.interleaved_layered_dpb_video_layout

dancingmirrors 72177c94e1 hasvk: Fix the length in MFX_AVC_SLICE_STATE. 2026-07-21 22:25:26 +03:00
dancingmirrors 083ee5051c hasvk: Properly handle complementary field pairs. 
The else branch here was also unreachable.
Fixes the poisoned first field in https://files.lynne.ee/testsamples/bbc2.sample.h264.

dancingmirrors 22ce819de6 hasvk: Account for unsupported shaderStorageImageReadWithoutFormat. 
When mpv creates the bwdif_vulkan filter we can sometimes see
exactly what's happening:
shaderStorageImageReadWithoutFormat support is false, but
shaderStorageImageWriteWithoutFormat support is true.
SPIR-V complains and then the GPU hangs since elk can't do the
necessary lowering. See here:
if (var->data.image.format == PIPE_FORMAT_NONE)
   return false;
To make deinterlacing work again the fix probably needs to be in
FFmpeg. See its commit 779763181f85bf25c53af5789d8b9b99d3bb0d1d.

dancingmirrors cd1018d5ea hasvk: Advertise VK_KHR_internally_synchronized_queues. 
Advertise the extension and feature and accept the internally synchronized
queue create flag. FFmpeg has deprecated its own queue locking mechanism.

dancingmirrors 2e5cca4d05 hasvk: Properly handle interlaced video. 
There was no handling here at all so the GPU would just hang immediately.

dancingmirrors 0f70099a69 hasvk: Reject result status queries on the video decode queue. 
Inline queries enabled by video_maintenance1 would just lock up my
machine and I'm not sure a proper workaround exists.

A few nits while here.

dancingmirrors c3fe6d4a87 hasvk: Rename genX_video.c to genX_cmd_video.c to match ANV. 2026-07-21 22:08:59 +03:00
dancingmirrorsandirql-notlessorequal 9dad5c1a52 hasvk: Add a slice header parser for H.264 decode. 
This is required for long mode, where the driver parses the slice header
itself rather than relying on the hardware to do it.
