>From the moment the cmdparser was enabled (4.0) we got regression reports about the performance regression, e.g. most notable on Baytrail http://www.spinics.net/lists/dri-devel/msg80933.html msg->id:1428627643.3417.22.camel@xxxxxxxxxxxxx Whilst this doesn't make the cmdparser free, it does significantly reduce the overhead. (The cached vmappings and better hash were tested at the time and demonstrated to reduce the impact on the user's workload to the point where the new kernel was an improvement over the last known good). This builds upon the regression fixes to stop the cmdparser falling over in the first place. -Chris _______________________________________________ Intel-gfx mailing list Intel-gfx@xxxxxxxxxxxxxxxxxxxxx https://lists.freedesktop.org/mailman/listinfo/intel-gfx
