MTL introduces additional OA units dedicated to media use cases. Add support for programming these OA units by passing the media engine class and instance parameters. UMD specific changes for GPUvis support: https://patchwork.freedesktop.org/patch/522827/?series=114023 https://patchwork.freedesktop.org/patch/522822/?series=114023 https://patchwork.freedesktop.org/patch/522826/?series=114023 https://patchwork.freedesktop.org/patch/522828/?series=114023 https://patchwork.freedesktop.org/patch/522816/?series=114023 https://patchwork.freedesktop.org/patch/522825/?series=114023 v2: (Ashutosh) - check for IP_VER(12, 70) instead of MTL - remove PERF_GROUP_OAG comment in mtl_oa_base - remove oa_buffer.group - use engine->oa_group->type in engine_supports_oa_format - remove fw_domains and use FORCEWAKE_ALL - remove MPES/MPEC comment - s/xehp/mtl/ in b counter validation function name - remove engine_supports_oa in __oa_engine_group - remove warn_ON from __oam_engine_group - refactor oa_init_groups and oa_init_regs - assign g->type correctly - use enum oa_type definition v3: (Ashutosh) - Drop oa_unit_functional as engine_supports_oa is enough v4: - s/DRM_DEBUG/drm_dbg/ Signed-off-by: Umesh Nerlige Ramappa <umesh.nerlige.ramappa@intel.com> --- drivers/gpu/drm/i915/i915_drv.h | 2 + drivers/gpu/drm/i915/i915_pci.c | 1 + drivers/gpu/drm/i915/i915_perf.c | 184 ++++++++++++++++++++--- drivers/gpu/drm/i915/i915_perf_oa_regs.h | 78 ++++++++++ drivers/gpu/drm/i915/i915_perf_types.h | 30 ++++ drivers/gpu/drm/i915/intel_device_info.h | 1 + include/uapi/drm/i915_drm.h | 4 + 7 files changed, 278 insertions(+), 22 deletions(-)
