[Bug]: media-driver on kernel 6.2-rc6 and DG2 hardware fails execbuffer ioctl #1602

Closed airlied closed 1 year ago

Which component impacted?

Decode

Is it regression? Good in old configuration?

No, this issue exist a long time

What happened?

With kernel 6.2.0-rc6 and latest media-driver on a DG2 system (tested on a380 and a770), av1 decode fails, digging in I found execbuffer was failing due to

i915_gem_execbuffer.c:eb_capture_stage is where it fails

                if (i915_gem_context_is_recoverable(eb->gem_context) &&
                    (IS_DGFX(eb->i915) || GRAPHICS_VER_FULL(eb->i915) > IP_VER(12, 0)))
                        return -EINVAL;

I assume this is media-driver doing something it shouldn't.

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

Playback

This should be incompatible issue of i915 error capture and recoverable ctx involved by i915 change. Suppose media driver has disabled i915 error capure temporarily. @Dylan-debug can you comment and share the commit.

This was fixed in the latest tag is intel-media-23.1.0 https://github.com/intel/media-driver/commit/6b210dd1ec8b568f8760c80d31d5cf3ac86c501a.

22.6.5 and 22.6.6 are two broken versions for using DG2 with upstream kernel.

yes indeed updating to master seems to have fixed it, not sure why I dropped back to an earlier release, I was debugging something else.
