[Intel-gfx] [PATCH 1/3] drm/i915: Initialise basic fence before acquiring seqno

[Intel-gfx] [PATCH 1/3] drm/i915: Initialise basic fence before acquiring seqno

[Chris Wilson]

Inside the intel_timeline_get_seqno(), we currently track the retirement
of the old cachelines by listening to the new request. This requires
that the new request is ready to be used and so requires a minimum bit
of initialisation prior to getting the new seqno.

[Intel-gfx] [PATCH 2/3] drm/i915/gt: Warn about the hidden i915_vma_pin in timeline_get_seqno

[Chris Wilson]

On seqno rollover, we need to allocate ourselves a new cacheline. This
might incur grabbing a new page and pinning it into the GGTT, with some
rather unfortunate lockdep implications.

To avoid a mutex, and more specifically pinning in the GGTT from inside
the kernel context being used to flush the GGTT in emergencies, we will
likely need to lift the next-cacheline allocation to a pre-reservation.

[Intel-gfx] [PATCH 3/3] drm/i915/selftests: Add a simple rollover for the kernel context

[Chris Wilson]

Exercise the seqno wrap paths on the kernel context to provide a small
amount of sanity checking and ensure that they are visible to lockdep.
