[Bug]: vaGetImage takes 90ms on each FullHD frame

Which component impacted?

Video Processing

Is it regression? Good in old configuration?

This issue doesn't reproduce with i965 driver

What happened?

This happens on a certain hardware with UHD Graphics 605 GPU.

This issue seems to happen on all the versions of iHD_driver, we checked on 20.1.1 iHD and 23.4.1 . Reproduces with both ffmpeg and gstreamer (all latest versions), and any Full HD video.

How to reproduce:

$ wget https://test-videos.co.uk/vids/bigbuckbunny/mkv/1080/Big_Buck_Bunny_1080_10s_1MB.mkv

$ ffmpeg -y -an -hwaccel vaapi -hwaccel_device /dev/dri/renderD128 -hwaccel_output_format vaapi -i Big_Buck_Bunny_1080_10s_1MB.mkv -vf hwdownload,format=nv12 -f null

so in the output of ffmpeg we can see it only reaches ~10 fps.

Same 10 fps are reached if we download with gstreamer vah264dec element

gst-launch-1.0 -v filesrc location=Big_Buck_Bunny_1080_10s_1MB.mkv ! parsebin ! vah264dec ! "video/x-raw" ! fpsdisplaysink video-sink=fakesink sync=false

Checking the libva traces we can see that the slowest part is the vaGetImage, it always takes around 90-100ms

[20491.582113][ctx       none]=========vaCreateImage ret = VA_STATUS_SUCCESS, success (no error) 
[20491.680938][ctx       none]=========vaGetImage ret = VA_STATUS_SUCCESS, success (no error)

Meanwhile without downloading to CPU memory the playback of the same file can reach 700fps. To give an approximate benchmark of the CPU - software decoding of the same file reaches 300 fps, so it's not that incredibly slow.

Do you know a way to confirm it's a hardware or a driver issue?

What's the usage scenario when you are seeing the problem?
