 1.17  11-Jul-2022  riastradh i915: Defer destroying waitqueue until after callback is removed.

Candidate fix for PR kern/56561.
 1.16  27-Dec-2021  riastradh i915: Fix timeout return value of i915_request_wait.

For some reason this returns ETIME, not ETIMEDOUT or 0 like most
other wait-with-timeout things in Linux.
 1.15  27-Dec-2021  riastradh i915: Factor a little out of #ifdef NetBSD.

Doesn't really reduce diff but slightly reduces danger of bad merge.
 1.14  27-Dec-2021  riastradh i915: Omit diff now that TASK_INTERRUPTIBLE is defined.
 1.13  21-Dec-2021  thorpej - For kmem_cache_create_dtor(), use a pre-destructor to issue the
synchronize_rcu() if the caller uses SLAB_TYPESAFE_BY_RCU. A
special pool allocator is not required in this case.
- Now that SLAB_TYPESAFE_BY_RCU does the right thing, no need to
call synchronize_rcu() in __i915_request_dtor().
 1.12  19-Dec-2021  riastradh i915: Fix locking-against-self in i915_request_wait.
 1.11  19-Dec-2021  riastradh i915: Kludge: wait for RCU grace period in __i915_request_dtor.

Unfortunately, pool_cache_put does not guarantee that an RCU or
pserialize grace period has completed before it invokes the pool
cache's destructor. This is likely to kill performance...
 1.10  19-Dec-2021  riastradh i915: Defer i915_sw_fence_fini to `kmem' (pool) cache destructor.

We actually need to destroy the spin lock here, whereas in Linux this
is only used for tracking when sw fences are _technically_ in use or
not -- where `not in use' includes RCU grace periods -- and it's OK
to `destroy' a fence while the grace periods are still running.
 1.9  19-Dec-2021  riastradh i915: Defer destroying request lock and fence until page destruction.
 1.8  19-Dec-2021  riastradh i915: Reduce diff with -Wno-pointer-arith.
 1.7  19-Dec-2021  riastradh i915: Must unmake vma nodes we have made.
 1.6  19-Dec-2021  riastradh i915: Use dma_fence_signal_locked when we already hold the lock.
 1.5  19-Dec-2021  riastradh i915: Adapt i915_request.
 1.4  19-Dec-2021  riastradh misc drm hacks
 1.3  19-Dec-2021  riastradh First pass at i915, far from complete.
