2017-04-11drm/i915: Generate the engine name based on the instance numberOscar Mateo

2017-03-31drm/i915: Clear gt.active_requests before checking idle statusChris Wilson
commit 8490ae207f1d ("drm/i915: Suppress busy status for engines if wedged") moved the check for inflight requests to the intel_engines_are_idle() check to protect the idle worker. However, the request selftests were also checking the engine idle status and erroring out if they did not become idle within a short period of time after the final wait. In order to accommodate the new check, call retire requests prior to the engine check so that we flush all the waits.

I915_RESET_IN_PROGRESS is being used for both signaling the requirement to i915_mutex_lock_interruptible() to avoid taking the struct_mutex and to instruct a waiter (already holding the struct_mutex) to perform the reset.

2017-02-23drm/i915: Protect the request->global_seqno with the engine->timeline lockChris Wilson
A request is assigned a global seqno only when it is on the hardware execution queue. The global seqno can be used to maintain a list of requests on the same engine in retirement order, for example for constructing a priority queue for waiting. Prior to its execution, or if it is subsequently removed in the event of preemption, its global seqno is zero. As both insertion and removal from the execution queue may operate in IRQ context, it is not guarded by the usual struct_mutex BKL. Instead those relying on the global seqno must be prepared for its value to change between reads. Only when the request is complete can the global seqno be stable (due to the memory barriers on submitting the commands to the hardware to write the breadcrumb, if the HWS shows that it has passed the global seqno and the global seqno is unchanged after the read, it is indeed complete).

2017-02-14drm/i915: Emit to ringbuffer directlyTvrtko Ursulin
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.

2017-02-13drm/i915: Use fault-injection to force the shrinker to run in live GTT testsChris Wilson
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.
