2018-04-03tests/gem_eio: Never re-use contexts which were in the middle of GPU resetTvrtko Ursulin
Contexts executing when reset triggers are potentialy corrupt so trying to use them from a subsequent test (like the default context) can hang the GPU or even the driver. Workaround that by always creating a dedicated context which will be running when GPU reset happens. v2: * Export and use gem_reopen_device so the test works on old gens as well.

2018-03-22igt/gem_measure_ring_size_inflight: Measure smallest inflight ring sizeAntonio Argenziano
Some tests measure the render's ring size but are actually meant to measure the smallest across all engines. This patch adds measuring the smallest size in gem_measure_ring_size_inflight() given the appropriate parameter. v2: - Only expose high level API. (Chris) v3: - Use ALL_ENGINES macro.

2018-03-22lib: Run gem_test_engine() in an isolated contextChris Wilson
Ignore the shennigans of the test surrounding the library call to gem_test_engine() and focus on answering the query of whether the engine exists and is operational.

2018-03-20igt: Replace 'all-engines' magic numbers with macroAntonio Argenziano
In interfaces where a parameter allow to select an engine, we usually use '-1' or '~0u' to select all engines. This patch replaces magic numbers with a named constant.

2018-03-07Bump measure_ring_size() timer intervalChris Wilson
It appears that waiting for a 100us period whereby we are unable to submit another batch and proclaim the ring full, may have the false positive where the scheduler intervenes and we are signalled twice before having slept on ring space. Increasing the interval reduces the likelihood of the scheduler stealing the cpu from us, but does not eliminate it. Fortuitously it appears to be a rare false positive. For the library routine, we can fork a RT process but that seems a bit overkill!

2018-02-23lib/igt_gt: add intel_measure_ring_sizeDaniele Ceraolo Spurio
The logic to measure the ring size is replicated almost identically in several tests. Adding it as a common function will make the code cleaner. The tests are updated in follow up patches. v2: - Move into a new file: 'gem_ring'. (Chris) v3: - Rename ring measure function.

2018-02-07lib: Move __gem_context_create to common ioctl wrapper library.Antonio Argenziano
This patch adds a context creation ioctl wrapper that returns the error for the caller to consume. Multiple tests that implemented this already, have been changed to use the new library function. v2: - Add gem_require_contexts() to check for contexts support (Chris) v3: - Add gem_has_contexts to check for contexts support and change gem_require_contexts to skip if contests support is not available. (Chris) v4: - Cosmetic changes and use lib function in gem_ctx_create where possible. (Michal) v5: - Use gem_contexts_require() in tests and fixtures.

2017-12-15lib: Provide a library function to test nop executionChris Wilson
Sometimes a test wants to verify that an engine, or all of them, are functional by executing a nop batch. Provide a common routine to submit an empty batch then test whether the driver is wedged.

The MMAP_V2 is replaced by just using MMAP, since the official header has the updated struct. The gem_create_v2 and gem_get_aperture are left as is, because they seem to not be reflected in the UABI header!
