Damien Lespiau	76ea7b9133	tests/stats: Make sure we properly invalidate the cached mean ... Sure, that's an implementation details, but make sure we do recompute the mean when we add a new value. Signed-off-by: Damien Lespiau <damien.lespiau@intel.com>	2015-06-27 16:03:27 +01:00
Damien Lespiau	515cec1210	stats: Add a way to retrieve the standard deviation ... Signed-off-by: Damien Lespiau <damien.lespiau@intel.com>	2015-06-27 16:03:27 +01:00
Damien Lespiau	9986282c2b	tests/igt_stats: Call igt_stats_fini() to not leak the array ... Sure, it'll be freed at exit(), but might as well be a bit pedantic. Signed-off-by: Damien Lespiau <damien.lespiau@intel.com>	2015-06-27 16:03:27 +01:00
Damien Lespiau	e55a11d3eb	stats: Be more precise and talk about mean, not average ... There are several types of averages eg. mean, median and mode. Signed-off-by: Damien Lespiau <damien.lespiau@intel.com>	2015-06-27 16:03:27 +01:00
Damien Lespiau	06f5f7065f	lib: Add a tiny utility function to compute averages ... The master plan would be to get a bit more stats in it, at least the standard deviation and confidence interval. Just need the average for now. Signed-off-by: Damien Lespiau <damien.lespiau@intel.com>	2015-06-25 17:22:03 +01:00
