Umesh Nerlige Ramappa 2a264a0fd4 drm/i915/perf: Allow non-privileged access when OA buffer is not sampled ... SAMPLE_OA_REPORT enables sampling of OA reports from the OA buffer. Since reports from OA buffer had system wide visibility, collecting samples from the OA buffer was a privileged operation on previous platforms. Prior to TGL, it was also necessary to sample the OA buffer to normalize reports from MI REPORT PERF COUNT. TGL has a dedicated OAR unit to sample perf reports for a specific render context. This removes the necessity to sample OA buffer. - If not sampling the OA buffer, allow non-privileged access. An earlier patch allows the non-privilege access: https://patchwork.freedesktop.org/patch/337716/?series=68582&rev=1 - Clear up the path for non-privileged access in this patch Signed-off-by: Umesh Nerlige Ramappa <umesh.nerlige.ramappa@intel.com> Fixes: 00a7f0d715 ("drm/i915/tgl: Add perf support on TGL") Reviewed-by: Lionel Landwerlin <lionel.g.landwerlin@intel.com> Signed-off-by: Lionel Landwerlin <lionel.g.landwerlin@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20191206194339.31356-1-umesh.nerlige.ramappa@intel.com (cherry picked from commit 322d56aa31) Signed-off-by: Joonas Lahtinen <joonas.lahtinen@linux.intel.com>		2019-12-10 12:37:52 +02:00
