[Intel-gfx] [CI 1/3] drm/i915: Remove livelock from "do_idle_maps" vtd w/a

[Chris Wilson]

A call to wait for the GT to idle from inside the put_pages fallback is
prone to cause an uninterruptible livelock. As it does not provide
adequate serialisation with new requests, simply fallback to a trivial
sleep.

[Intel-gfx] [CI 2/3] drm/i915: Sleep around performing iommu unmaps on Tigerlake

[Chris Wilson]

Tigerlake is plagued by spontaneous DMAR faults [reason 7, next page
table ptr is invalid] which lead to GPU hangs. These faults occur when
an iommu map is immediately reused. Adding further clflushes and
barriers around either the GTT PTE or iommu PTE updates do not prevent
the faults. So far the only effect has been from inducing a delay
between reuse of the iommu on the GPU, and applying the delay at the
iommu map allows for the smallest stable delay.

Note that such a delay clearly does not fix the root cause, and so
should only be a bandaid until a complete solution is found. The delay
was determined by running igt/gem_exec_fence/parallel in a loop for a
few hours (unpatched MTBF is about 10s).
