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.

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.

There was no handling here at all so the GPU would just hang immediately.

This is required for long mode, where the driver parses the slice header
itself rather than relying on the hardware to do it.

Kenneth Graunke 203bf6b58d hasvk: Make a batch decoder for each queue family 
The decoder context needs to know what engine it's associated with.
Nowadays, we have render, compute, blitter, even video engines being
used from the same driver.  Rather than trying to have a single decoder
and thwacking the engine field back and forth between calls, we make
one per queue family, and stash a pointer in anv_queue for easy access.
