shows us that our preemption logic for Tigerlake is snafu. I assume we need an update to the semaphore wait.
Comment 3 Chris Wilson 2019-09-17 16:43:11 UTC
commit c210e85b8f3371168ce78c8da00b913839a84ec7 (HEAD -> drm-intel-next-queued, drm-intel/drm-intel-next-queued)
Author: Chris Wilson <chris@chris-wilson.co.uk>
Date:   Tue Sep 17 13:30:55 2019 +0100

    drm/i915/tgl: Extend MI_SEMAPHORE_WAIT
    
    On Tigerlake, MI_SEMAPHORE_WAIT grew an extra dword, so be sure to
    update the length field and emit that extra parameter and any padding
    noop as required.
    
    v2: Define the token shift while we are adding the updated MI_SEMAPHORE_WAIT
    v3: Use int instead of bool in the addition so that readers are not left
    wondering about the intricacies of the C spec. Now they just have to
    worry what the integer value of a boolean operation is...
