2017-08-04tests/perf: improve robustness of polling/blocking testsRobert Bragg
There were a couple of problems with both of these tests that could lead to false negatives addressed by this patch. 1) The upper limit for the number of iterations missed a +1 to consider that there might be a sample immediately available at the start of the loop. 2) The tests didn't consider that a duration measured in terms of (end-start) ticks could be +- 1 tick since we don't know the fractional part of the tick counts. Our threshold for stime being < one tick could have a false negative for any real stime between 1 to 10 milliseconds depending on luck. The tests now both run for a lot longer (1000 x tick duration, or typically 10 seconds each) so that a single tick represents a much smaller proportion of the total duration (0.1%) and the stime thresholds are now set at 1% of the total duration.

2017-03-24lib/debugfs: Phase out igt_debugfs_fopen()Chris Wilson
Wrapping fdopen() proved dangerous, the underlying fd is not refcounted, and we must close it in the library or else we easily leak and exhaust all fd. Since we can't provide igt_debugfs_fopen(), move the burden onto the caller for those that require a stream FILE*. Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>

This reverts commit 301ad44cdf1b868b1ab89096721da91fa8541fdc. When a render-only device is opened and gem_quiescent_gpu is called, we need to use the debugfs dir for the master device instead. Signed-off-by: Tomeu Vizoso <tomeu.vizoso@collabora.com>
2017-03-21lib: Open debugfs files for the given DRM deviceTomeu Vizoso
When opening a DRM debugfs file, locate the right path based on the given DRM device FD. This is needed so, in setups with more than one DRM device, any operations on debugfs files affect the expected DRM device. v2: - rebased and fixed new API additions v3: - updated chamelium test, which was missed previously - use the minor of the device for the debugfs path, not the major - have a proper exit handler for calling igt_hpd_storm_reset with the right device fd.
