How can I get kgsl information on ui.perfetto.dev

[simowce go]

Hi all:

I have noticed that perfetto has already add kgsl ftrace support on this commit:

commit 1371648c47324a835c9dc19ed63c13c739b01fd4 提交 1371648c47324a835c9dc19ed63c13c739b01fd4

    Enable kgsl ftrace event capture 启用 kgsl ftrace 事件捕获

    This include the events of 'adreno_cmdbatch_sync', 'adreno_cmdbatch_queued', 'adreno_cmdbatch_submitted', 'adreno_cmdbatch_retired'.

My question is: I have already add these ftrace on my perfetto config:

data_sources: {
    config {
        name: "linux.ftrace"
        ftrace_config {
            ftrace_events: "kgsl/adreno_cmdbatch_sync"
            ftrace_events: "kgsl/adreno_cmdbatch_queued"
            ftrace_events: "kgsl/adreno_cmdbatch_submitted"
            ftrace_events: "kgsl/adreno_cmdbatch_retired"

How can I get these kgsl information on ui.perfetto.dev

Thanks a lot~
如何在 ui.perfetto.dev 上获取这些 kgsl 信息

1) These events are only available on some devices, it's possible your device does not support them

2) If the event was available on your device, it will show up in the "Ftrace Events" section of the UI. You might need to add the ftrace events panel by clicking on the three dots on the left side bottom panel and then choosing "Ftrace Events". You should then be able to filter to just those events.

Yes it's possible. Patches welcome.

Thanks for your answer, I have get the information from the Ftrace Event panel.

I got a another idea, is that possible to parse these kgsl ftrace and add some slices to represent the kgsl gpu status? If it's possible, how can I do? Is there any BEST practice or HOW-TO ?

Thanks again!
