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.

2017-09-25igt/gem_exec_whisper: Smoketest context prioritiesChris Wilson
No complex check of reordered writes, just throwing lots of random priority batches with long dependency chains at the scheduler. This should help to smoketest preemption. Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>

2017-03-21Revert "lib: Open debugfs files for the given DRM device"Tomeu Vizoso
This reverts commit 301ad44cdf1b868b1ab89096721da91fa8541fdc. When a render-only device is opened and gem_quiescent_gpu is called, we need to use the debugfs dir for the master device instead. Signed-off-by: Tomeu Vizoso <tomeu.vizoso@collabora.com>
2017-03-21lib: Open debugfs files for the given DRM deviceTomeu Vizoso
When opening a DRM debugfs file, locate the right path based on the given DRM device FD. This is needed so, in setups with more than one DRM device, any operations on debugfs files affect the expected DRM device. v2: - rebased and fixed new API additions v3: - updated chamelium test, which was missed previously - use the minor of the device for the debugfs path, not the major - have a proper exit handler for calling igt_hpd_storm_reset with the right device fd.

2016-10-05igt/gem_exec_whisper: Tweaking the global seqno is not multiuser safeChris Wilson
If we want to advance the seqno, we need to coordinate with all possible users. The kernel doesn't want to do that for a lowlevel debug feature, so it's up to userspace not to shoot itself in the foot. Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>

2016-06-04igt/gem_exec_whisper: Another twist on engine interchangeChris Wilson
Slightly less extreme than switching engines between commands, switch engines between pixels. This helps contrast the request amalgamation in execlists. Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>

2016-05-20igt/gem_exec_whisper: Exclude from BATChris Wilson
At its heart gem_exec_whisper is a race detector between submission between multiple rings and the execution. It is made even more unreliable by debug kernels making it nigh impossible to submit batches faster than the GPU can execute. As such, it's relevance for BAT is dubious.

2016-05-12lib/igt_aux: Polish docs for igt_interruptibleDaniel Vetter
- Give __ prefix to internal funcstion and structs, only igt_interruptible is used by tests. - Move docs to igt_interruptible and adjust. - Explain more clearly how the timeout is getting doubled each iteration until no more interruptions happen. Also rename the argument to give it a more meaningful name in the docs. - Link from other functions to this one for cross-referencing. - Rename to igt_do_interruptible to make it clearer it's a loop, inspired by do {} while () loops. v2: Rename instead to igt_while_interruptible and fix typos (Chris).

2016-03-24lib: Add a GPU error detectorChris Wilson

2016-03-15igt/gem_exec_whisper: Beware PIN_HIGHChris Wilson

2016-03-11tests: Add gem_exec_whisperChris Wilson
A more complicated store variant to stress inter-engine dependencies (i.e. semaphores and sync). We write a control value from one batch into the next and then execute it. This is repeated a few times with each execution happening on a different engine (so the kernel has to serialise operations between engines) until we finally write the value out into our scratch buffer where we can check the result, just like a Chinese whisper.
