2017-02-14drm/atomic: Add new iterators over all state, v3.Maarten Lankhorst3-15/+69
Add for_each_(old)(new)_(plane,connector,crtc)_in_state iterators to replace the old for_each_xxx_in_state ones. This is useful for >1 flip depth and getting rid of all xxx->state dereferences. This requires extra fixups done when committing a state after duplicating, which in general isn't valid but is used by suspend/resume. To handle these, introduce drm_atomic_helper_commit_duplicated_state which performs those fixups before checking & committing the state. Changes since v1: - Remove nonblock parameter for commit_duplicated_state. Changes since v2: - Use commit_duplicated_state for i915 load detection. - Add WARN_ON(old_state != obj->state) before swapping.

2017-02-14drm/i915: Emit to ringbuffer directlyTvrtko Ursulin12-719/+617
This removes the usage of intel_ring_emit in favour of directly writing to the ring buffer. intel_ring_emit was preventing the compiler for optimising fetch and increment of the current ring buffer pointer and therefore generating very verbose code for every write. It had no useful purpose since all ringbuffer operations are started and ended with intel_ring_begin and intel_ring_advance respectively, with no bail out in the middle possible, so it is fine to increment the tail in intel_ring_begin and let the code manage the pointer itself. Useless instruction removal amounts to approximately two and half kilobytes of saved text on my build. Not sure if this has any measurable performance implications but executing a ton of useless instructions on fast paths cannot be good. v2: * Change return from intel_ring_begin to error pointer by popular demand. * Move tail increment to intel_ring_advance to enable some error checking. v3: * Move tail advance back into intel_ring_begin. * Rebase and tidy. v4: * Complete rebase after a few months since v3. v5: * Remove unecessary cast and fix !debug compile. (Chris Wilson) v6: * Make intel_ring_offset take request as well. * Fix recording of request postfix plus a sprinkle of asserts. (Chris Wilson) v7: * Use intel_ring_offset to get the postfix. (Chris Wilson) * Convert GVT code as well. v8: * Rename *out++ to *cs++. v9: * Fix GVT out to cs conversion in GVT. v10: * Rebase for new intel_ring_begin in selftests.

It is possible whilst allocating the page-directory tree for a ppgtt bind that the shrinker may run and reap unused parts of the tree. If the shrinker happens to remove a chunk of the tree that the allocate_va_range has already processed, we may then try to insert into the dangling tree. This test uses the fault-injection framework to force the shrinker to be invoked before we allocate new pages, i.e. new chunks of the PD tree.
