2018-07-06lib: Convert spin batch constructor to a factoryChris Wilson
In order to make adding more options easier, expose the full set of options to the caller. Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk> Cc: Tvrtko Ursulin <tvrtko.ursulin@intel.com> Cc: Petri Latvala <petri.latvala@intel.com> Reviewed-by: Tvrtko Ursulin <tvrtko.ursulin@intel.com>
2018-05-03igt/gem_exec_fence: Exercise merging fencesChris Wilson
Execute the same batch on each engine and check that the composite fence across all engines completes only after the batch is completed on every engine. Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk> Reviewed-by: Antonio Argenziano <antonio.argenziano@intel.com>
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.

2018-03-07Bump 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!

2018-02-23Iterate over physical enginesChris Wilson
We current have a single for_each_engine() iterator which we use to generate both a set of uABI engines and a set of physical engines. Determining what uABI ring-id corresponds to an actual HW engine is tricky, so pull that out to a library function and introduce for_each_physical_engine() for cases where we want to issue requests once on each HW ring (avoiding aliasing issues). v2: Remember can_store_dword for gem_sync v3: Find more open-coded for_each_physical Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk> Cc: Tvrtko Ursulin <tvrtko.ursulin@intel.com> Reviewed-by: Tvrtko Ursulin <tvrtko.ursulin@intel.com>

2018-02-21igt/gem_ctx_isolation: Check isolation of registers between contextsChris Wilson
A new context assumes that all of its registers are in the default state when it is created. What may happen is that a register written by one context may leak into the second, causing mass confusion. v2: Extend back to Sandybridge (etc) v3: Check context preserves registers across suspend/hibernate and resets. v4: Complete the remapping onto the new class:instance v5: Not like that, like this, try again to use class:instance v6: Prepare for retrospective gen4 contexts! v7: Repaint register set name to nonpriv, as this is what bspec calls the registers that are writable by userspace. v8: Fix a typo for LRM on gen8 Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk> Cc: Joonas Lahtinen <joonas.lahtinen@linux.intel.com> Reviewed-by: Joonas Lahtinen <joonas.lahtinen@linux.intel.com>

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.

Only with execlists, is each context using a separate ring buffer and we can accumulate as many fences as contexts we can allocate. On the hand, systems with just a single ring buffer for all contexts, we can only allocate enough contexts/fences as to fill the ring. If we try to add to many we end up stuck waiting for space.
