From: Chris Wilson <chris@xxxxxxxxxxxxxxxxxx> This bit was fliped on for "syncing dependencies between camera and graphics". BSpec has no recollection why, and it is causing unrecoverable GPU hangs with Vulkan compute workloads. >From BSpec, setting bit5 to 0 enables relaxed padding requirements for buffers, 1D and 2D non-array, non-MSAA, non-mip-mapped linear surfaces; and *must* be set to 0h on skl+ to ensure "Out of Bounds" case is suppressed.
