Subject: [PATCH v2 0/2] drm: Add GPU frequency tracepoint
Date: Mon, 8 Sep 2025 18:26:31 +0530 [thread overview]
Message-ID: <20250908125633.2680617-1-s.sebinraj@intel.com> (raw)
Add a GPU frequency tracepoint at the DRM subsystem level.
Integrates with the Xe PMU to provide frequency tracing.
The tracepoint is exposed at:
/sys/kernel/debug/tracing/events/power/gpu_frequency
Format: {unsigned int state, unsigned int gpu_id}
- state: GPU frequency in KHz
- gpu_id: GPU clock domain identifier
