| ## GPU Frequency |
| |
| GPU frequency can be included in the trace by adding the ftrace category. |
| |
| ``` |
| data_sources: { |
| config { |
| name: "linux.ftrace" |
| ftrace_config { |
| ftrace_events: "power/gpu_frequency" |
| } |
| } |
| } |
| ``` |
| |
| ## GPU Counters |
| |
| GPU counters can be configured by adding the data source to the trace config as follows: |
| |
| ``` |
| data_sources: { |
| config { |
| name: "gpu.counters" |
| gpu_counter_config { |
| counter_period_ns: 1000000 |
| counter_ids: 1 |
| counter_ids: 3 |
| counter_ids: 106 |
| counter_ids: 107 |
| counter_ids: 109 |
| } |
| } |
| } |
| ``` |
| |
| The counter_ids correspond to the ones described in `GpuCounterSpec` in the data source descriptor. |
| |
| See the full configuration options in [gpu\_counter\_config.proto](/protos/perfetto/config/gpu/gpu_counter_config.proto) |
