不同场景systrace tag_fpsgo

CPU sched

使用Perfconv抓取

请参考perfconv抓取fpsgo以及schedule相关tag

使用systrace抓取

kernel-5.10 

频率和摆核信息都抓取：

sched_migrate_task sugov_ext_util sched_task_uclamp sched_select_task_rq sched_queue_task sched_frequency_limits sched_find_energy_efficient_cpu sched_big_task_rotation sched_force_migrate sched_waking irq

只抓摆核的

sched_select_task_rq sched_force_migrate sched_migrate_task sched_queue_task

只抓调频的

sugov_ext_util sched_frequency_limits freq_qos_user_setting sched_queue_task

比如在您的脚本里这样设置：

        adb shell "echo 1 > /sys/kernel/tracing/events/sched/sched_blocked_reason/enable"
        adb shell "echo 1 > /sys/kernel/tracing/events/sched/sched_migrate_task/enable"
        adb shell "echo 1 > /sys/kernel/tracing/events/scheduler/sched_task_uclamp/enable"
        adb shell "echo 1 > /sys/kernel/tracing/events/scheduler/sugov_ext_util/enable"

        adb shell "echo 1 > /sys/kernel/tracing/events/sched/sched_waking/enable"
        adb shell "echo 1 > /sys/kernel/tracing/events/scheduler/sched_select_task_rq/enable"
        adb shell "echo 1 > /sys/kernel/tracing/events/scheduler/sched_find_energy_efficient_cpu/enable"
        adb shell "echo 1 > /sys/kernel/tracing/events/scheduler/sched_big_task_rotation/enable"
        adb shell "echo 1 > /sys/kernel/tracing/events/scheduler/sched_force_migrate/enable"

kernel-4.14 

sched 需要打开的 event：

sched_switch sched_wakeup sched_find_best_target sched_select_task_rq schedutil_uclamp_util sched_boost_cpu sched_boost_task cpu_frequency_limits cpu_frequency sched_hmp_migrate sched_util

IRQ 需要打开的 event：

/sys/kernel/tracing/events/scheduler/irq

irq_handler_entry
irq_handler_exit

work queue 需要打开的 event：

/sys/kernel/tracing/events/workqueue/
workqueue_execute_start
workqueue_execute_end
workqueue_queue_work
workqueue_activate_work

fpsgo

使用Perfconv抓取

请参考perfconv抓取fpsgo以及schedule相关tag

使用systrace抓取

请打开：

        adb shell "echo 63 > /sys/kernel/fpsgo/common/systrace_mask"        // this for fpsgo

        adb shell “echo 1 > /sys/kernel/fpsgo/xgf/xgf_trace_enable”
        adb shell “echo 1 > /sys/kernel/fpsgo/xgf/xgf_log_trace_enable”

CPU频率

如果发现CPU频率缺失，检查如下trace event有没有打开

/sys/kernel/tracing/events/power/cpu_frequency_limits/
cpu_frequency_limits
cpu_frequency
cpu_idle

DDR频率

需要打开的 systrace event:

adb shell "echo 1 > /sys/devices/system/cpu/perf/enable"

kernel-V4.1*版本：  adb shell "echo 1 > /sys/kernel/tracing/events/mtk_events/perf_index_s/enable"

kernel-V5.10版本：  adb shell "echo 1 > /sys/kernel/tracing/events/perf_tracker/perf_index_s/enable"

GPU频率

需要打开的 systrace event:

        adb shell "echo 1 > /sys/module/ged/parameters/ged_log_perf_trace_enable"   // these for GPU
        adb shell "echo 1 > /sys/devices/system/cpu/perf/enable"
        adb shell "echo 1 > /sys/module/ged/parameters/ged_log_trace_enable"

        adb shell "echo 1 > /sys/kernel/tracing/events/mtk_events/perf_index_gpu/enable"
        adb shell "echo 1 > /sys/kernel/tracing/events/perf_tracker/perf_index_gpu/enable"

生成systrace log:

       mtkPowerMsgHdl-762 ( 700) [005] ...1 37118.430645: tracing_mark_write: C|5566|gpu_freq|431|0|0
       mtkPowerMsgHdl-762 ( 700) [005] ...1 37118.430645: tracing_mark_write: C|5566|gpu_freq_max|886|0|0

Memory用量

需要打开的 systrace event:

adb shell "echo 1 > /sys/devices/system/cpu/perf/enable"

kernel-V4.1*版本：  adb shell "echo 1 > /sys/kernel/tracing/events/mtk_events/perf_index_l/enable"

kernel-V5.10版本：  adb shell "echo 1 > /sys/kernel/tracing/events/perf_tracker/perf_index_l/enable"

生成systrace log:

<idle>-0 (-----) [002] d.h1 2173.342581: perf_index_l: free_mem=853360 avail_mem=5227104 iostats=0|0|0|0|0|0|0|0|0|7992616|0 stall=3|0|0|0|0|0|0|0
