Mali has hardware cycle counters and GPU timestamps available for profiling. This patch series adds support for cycle counters propagation and also new timestamp info parameters. Those new changes to the uAPI will be used in Mesa to implement timestamp queries for OpenGL and Vulkan. The Mesa MR using this series is available here [1]. v2: - Rewrote to use GPU timestamp register - Add missing include for arch_timer_get_cntfrq - Squash job requirement uAPI changes and implementation in one patch - Simplify changes based on Steven Price comments [1]https://gitlab.freedesktop.org/mesa/mesa/-/merge_requests/30553 Mary Guillemard (2): drm/panfrost: Add SYSTEM_TIMESTAMP and SYSTEM_TIMESTAMP_FREQUENCY parameters drm/panfrost: Add cycle counter job requirement drivers/gpu/drm/panfrost/panfrost_drv.c | 43 ++++++++++++++++++++++-- drivers/gpu/drm/panfrost/panfrost_gpu.c | 12 +++++++ drivers/gpu/drm/panfrost/panfrost_gpu.h | 1 + drivers/gpu/drm/panfrost/panfrost_job.c | 28 +++++++++------ drivers/gpu/drm/panfrost/panfrost_regs.h | 2 ++ include/uapi/drm/panfrost_drm.h | 3 ++ 6 files changed, 76 insertions(+), 13 deletions(-) base-commit: dfa5543193f303a7270ec7c725e656970faf7d57 -- 2.45.2
