2018-05-15igt/gem_ctx_thrash: Order writes between contextsChris Wilson
The test wrote to the same dwords from multiple contexts, assuming that the writes would be ordered by its submission. However, as it was using multiple contexts without a write hazard, those timelines are not coupled and the requests may be emitted to hw in any order. So emit a write hazard for each individual dword in the scratch (avoiding the write hazard for the scratch as a whole) to ensure the writes do occur in the expected order.

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>
2018-02-07lib: 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.

2016-02-05igt/gem_ctx_thrash: Rewrite to avoid extraneous allocationsChris Wilson
The goal of the test is to exercise what happens when we fill the Global GTT with the contexts. To that end, we only need to allocate 2/4GiB of context objects, and can forgo filling each context with buffers.

No functional changes. While I'm here, let's also rename gem_uses_aliasing_ppgtt (since it's being used to indicate if we are using ANY kind of ppgtt) and introduce gem_uses_full_ppgtt to drop some unnecessary code from tests that were previously calling getparam directly instead of using ioctl wrapper. v2: drop gem_uses_full_48b_ppgtt since it's no longer used anywhere, s/48b/64b (Chris) v3: rebase Cc: Chris Wilson <chris@chris-wilson.co.uk> Signed-off-by: Michał Winiarski <michal.winiarski@intel.com> Reviewed-by: Chris Wilson <chris@chris-wilson.co.uk> Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch>
