pefetto config

[qiu]

Hello, I recently ran into problems with perfetto, which I configured val config = StringBuilder() .append("write_into_file: true\n") .append("flush_period_ms: 30000\n") .append("notify_traceur: true\n") .append("incremental_state_config {\n") .append(" clear_period_ms: 15000\n") .append("}\n") .append("file_write_period_ms: 1000\n") .append("buffers {\n") .append(" size_kb: 63488\n") .append(" fill_policy: RING_BUFFER\n") .append("}\n") .append("buffers {\n") .append(" size_kb: 2048\n") .append(" fill_policy: RING_BUFFER\n") .append("}\n") .append("data_sources: {\n") .append(" config {\n") .append(" name: \"android.surfaceflinger.layers\"\n") .append(" target_buffer: 1\n") .append(" surfaceflinger_layers_config: {\n") .append(" mode: MODE_UNSPECIFIED\n") .append(" trace_flags: TRACE_FLAG_INPUT\n") .append(" trace_flags: TRACE_FLAG_COMPOSITION\n") .append(" trace_flags: TRACE_FLAG_HWC\n") .append(" trace_flags: TRACE_FLAG_BUFFERS\n") .append(" trace_flags: TRACE_FLAG_VIRTUAL_DISPLAYS\n") .append(" }\n") .append(" }\n") .append("}\n") .append("duration_ms: 0\n") This configuration will catch the layer_trace file on user phones, but will catch the layer_trace,wm.log, and wm_trace files on root phones. Why is the wm file crawled by root
