2017-01-02igt: Mass conversion to to_user_pointer()Chris Wilson
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>
2016-08-23Revert "tests/gem_sync: Skip basic-store-each sub-test on BDW."Chris Wilson
This reverts commit 38f84e30e699451cac6c7b45cd603e67b1287f15.
2016-07-25tests/gem_sync: Skip basic-store-each sub-test on BDW.Marius Vlad
Causes too much noise in CI, so skip it for now. Signed-off-by: Marius Vlad <marius.c.vlad@intel.com>
2016-07-22lib/sysfs: Provide a convenience function for reading a boolChris Wilson
Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>
2016-07-22igt/gem_exec_nop: Display submission mechanismChris Wilson
Useful for confirmation when testing. Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>
2016-07-06igt/gem_sync: Fix uninitialised variable 'n'Chris Wilson
Not a good day. Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>
2016-07-05igt/gem_sync: Fix many_store() for printing out a single engineChris Wilson
The name for a single engine was unset, oops. 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).

2016-06-17tests: Push igt_fork/stop_hang_detector into fixturesDaniel Vetter
It access hardware, hence why the simple igt_only_list_subtests() check from igt_fork/stop_signal_helper() isn't enough. Signed-off-by: Daniel Vetter <daniel.vetter@intel.com>
2016-05-20igt/gem_sync: Drop individual engines from BATChris Wilson
Rely on testing every engine in parallel to detect the most common synchronisation problems ("missed interrupt syndrome") for BAT. Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>
2016-03-25igt/gem_sync: Add a basic test to wait upon a batch on all ringsChris Wilson
Execute the batch concurrently on all rings and then wait (as opposed to executing a different batch on each engine). Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>
2016-03-25igt/gem: Add GPU hang detection to basic testsChris Wilson
Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>
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>
2016-02-26igt/gem_sync: Test across all rings simultaneouslyChris Wilson
Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>
2016-02-26igt/gem_sync: Add some forked variantsChris Wilson
Repeat the synchronisation test with a few competing processes. Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>
2016-01-27igt/gem_sync: Use common array of ringsChris Wilson
Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>
2016-01-27lib: Share common __gem_execbuf()Chris Wilson
An oft-repeated function to check EXECBUFFER2 for a particular fail condition. Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>
2016-01-22lib: Refactor common detection of missed interruptsChris Wilson
As we have the same function in a few places to read the debugfs/i915_ring_missed_irq file, move it to the core. Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>
2016-01-17tests: Add basic gem_sync testChris Wilson
A very basic test of functionality, execute a nop and wait for it to complete. It should be very effective at stimulating the "missed interrupt syndrome" on all devices. Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>
