2016-07-22lib/sysfs: Provide a convenience function for reading a boolChris Wilson
Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>
2015-12-13igt/gem_read_read_speed: Tweak to show comparison against write-writeChris Wilson
Since we hold an exclusive write lock we expect 2 writes to happen serially, but we expect 2 reads to happen in parallel. Expand the testing to demonstrate this effect (i.e. we expect read-read to be roughly 2x faster than write-write for small copies on big core.) Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>

2015-08-21lib: add a single include headerThomas Wood
Add a header that includes all the headers for the library. This allows reorganisation of the library without affecting programs using it and also simplifies the headers that need to be included to use the library. Signed-off-by: Thomas Wood <thomas.wood@intel.com>
2015-03-18igt/gem_read_read_speed: Speed up batch submissionChris Wilson
Create the RCS and BCS batches once and reuse them to avoid the rewriting and relocation overhead on every submission - the goal is to focus on the interring synchronisation overhead. Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>
