2014-07-23igt/gem_userptr_benchmark: Fix for upstream ioctl numberTvrtko Ursulin
Hardcoding has upsides and downsides. Signed-off-by: Tvrtko Ursulin <tvrtko.ursulin@intel.com> Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch>
2014-04-25test/gem_userptr_*: Fix compile failDaniel Vetter
Also shut up warnings. Those revealed incorrect usage of local variables in conjunction with igt_fixture/igt_subtest. Since those use longjmps we need to move the out of the stackframe those magic blocks are declared in. Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch>
2014-04-25tests/gem_userptr_benchmark: Benchmarking userptr surfaces and impactTvrtko Ursulin
This adds a small benchmark for the new userptr functionality. Apart from basic surface creation and destruction, also tested is the impact of having userptr surfaces in the process address space. Reason for that is the impact of MMU notifiers on common address space operations like munmap() which is per process. v2: * Moved to benchmarks. * Added pointer read/write tests. * Changed output to say iterations per second instead of operations per second. * Multiply result by batch size for multi-create* tests for a more comparable number with create-destroy test. v3: * Use ALIGN macro. * Catchup with big lib/ reorganization. * Removed unused code and one global variable. * Fixed up some warnings. v4: * Fixed feature test, does not matter here but makes it consistent with gem_userptr_blits and clearer.
