2017-10-19lib/i915: Move submission related helpers to lib/i915/gem_submissionMichał Winiarski
Since I accidentally broke the build for some, by putting the pretty printer for submission inside ifdef HAVE_PROCPS, it's time to move the whole thing into lib/i915 while fixing this mistake. Let's also rename the pretty printer and add a doc to it as well as the section.

2017-10-17lib/i915: Extract helpers for determining scheduler capabilitiesMichał Winiarski
Couple of tests are using either determining scheduler capabilities or pretty printing. Let's move those to helpers in lib.

2017-09-29igt/gem_sync: Sync before starting the clockChris Wilson
Hide the initial setup cost of a new batch by performing it before we start the clock for measuring the execute-wait latency. Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk> Reviewed-by: Joonas Lahtinen <joonas.lahtinen@linux.intel.com>
2017-09-29igt/gem_sync: Add a preemption testChris Wilson
Check and measure how well we can submit a second high priority task when the engine is already busy with a low priority task and see how long it takes to complete (and wake up the client).

2017-02-04igt/gem_sync: Relax gen2 filteringChris Wilson
The most basic sync test uses a nop batch, no stores. This is safe to run on gen2. Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>

2016-10-18igt: Trim timeouts for basic GEM testsChris Wilson
It's a compromise between detecting an unlikely timing error in one test and being able to run a broader selection of tests. I hope this is wise. Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>

2016-07-05igt/gem_sync: Try and race the bottom-halfChris Wilson
In light of a bug in intel_breadcrumbs where we missed the interrupt when a new bottom half was installed and raced with the old bottom half being signaled, try and recreate that race. Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>
2016-07-04igt/gem_sync: Extend with store synchronisationChris Wilson
Currently gem_sync exploits read-read optimisation to wait upon multiple rings simultaneously. But at the moment, gem_exec_flush is showing sporadic missed interrupts on bdw/skl and yet gem_sync is not. This is some subtlety in the timing, perhaps caused by the extra write. This set of tests tries to exercise that by using a write batch - which also means we exercise inter-ring synchronisation (like gem_storedw_loop).

2016-03-25igt/gem_sync: Add a basic test to wait upon a batch on all ringsChris Wilson

2016-02-26igt/gem_sync: Enforce a timeout of 20sChris Wilson
The sync test is supposed to complete in 10s. But some bugs cause it to run very, very slowly. As a defence against those, terminate the test if we wait for more than 20s. Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>
