2017-06-07tests/gem_exec_nop: Rename signal() to fence_signal()Arkadiusz Hiler
Unfortunately <signal.h> is included through some obscure dependencies when using bionic, so we have a name clash on signal(). Changed the test function name to fence_signal() to avoid this, but left the test cases names unchanged.

2017-06-07tests/gem_exec_nop: Disable headless subtest on cairoless AndroidArkadiusz Hiler
Currently whole igt_kms.c is disabled while compiling on Android without cairo, so this tests does not compile. There should be cleaner a way to disable only cairo dependant parts which should allow us to enable at least some of the KMS tests, but that's a bigger rework for another time. v2: simplified #ifs on CAIRO/ANDROID (P.

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>

2016-09-08igt/gem_exec_nop: Refine the target calculationChris Wilson
The ideal execution time cannot be faster than the fastest ring! If all other rings were infinitely fast, the seed would be max/nengine. Given each is finite, this puts a floor on the ideal execution time. Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>

2016-09-08igt/gem_exec_nop: Relax assertion for parallel executionChris Wilson
In an ideal world, we should be able to execute on every engine in parallel and the single limiting factor would be how fast the GPU can execute. Due to the serialisation in execbuf, we would lockstep with execution to the slowest engine and so would execute the same number of cycles on each. However in CI, we are limited by how fast the driver is, particularly under invasive debugging. This makes asserting that the average time == max/nengine impossible, and reveals that the assertion is impossible to meet under general condition. It's an impractical regression test. Therefore we relax the assertion to only detect should something critically fail. Worst case behaviour is presumed that each ring runs sequentially, and so running N rings in parallel should take no longer than running N rings serially. (Pathologically it can be even slower if no batching on the rings occur). Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>

2013-11-01lib: add igt_main macroDaniel Vetter
In the past new testcases with subtest often forgot to add the call to igt_exit at the end of their main() function. That is now caught with a bit more obnoxious asserts, but it's still a nuissance. This little igt_main macro takes care of that (and also of calling the subtest machinery initialization code correctly).
