Add TRACE_GPU_MEM tracepoints for tracking global GPU memory usage. These are required by VSR on Android 12+ for reporting GPU driver memory allocations. v5: - Drop process_mem tracking - Set the gpu_id field to dev->primary->index (Lucas, Tvrtko) - Formatting cleanup under 80 columns v3: - Use now configurable CONFIG_TRACE_GPU_MEM instead of adding a per-driver Kconfig (Lucas) v2: - Use u64 as preferred by checkpatch (Tvrtko) - Fix errors in comments/Kconfig description (Tvrtko) - drop redundant "CONFIG" in Kconfig Signed-off-by: Juston Li <justonli@chromium.org> Reviewed-by: Tvrtko Ursulin <tvrtko.ursulin@igalia.com> Reviewed-by: Lucas De Marchi <lucas.demarchi@intel.com> Link: https://lore.kernel.org/r/20250709192313.479336-2-lucas.demarchi@intel.com Signed-off-by: Lucas De Marchi <lucas.demarchi@intel.com>
