CPU Clock: Frequency is not work. about gator

[haruzheng]

Hi @bengaineyarm

In Android R, the cpu_frequency event is block on bpfprogram.
You can ref android/ndk#1612 .
And fixed in https://android-review.googlesource.com/c/platform/system/bpfprogs/+/1913987 .

Thank you.

Hi @haruzheng - The clock frequency read function is only called once to collect the starting value of the clock, but then any later changes should be collected as PERF_TYPE_TRACEPOINT events.

Can you describe the problem you are seeing? Is it that the clock charts show a flat line (no change in frequency)? We have seen one Android phone recently where the clock frequency event never produces any perf events and the capture shows flat line for clock frequency.

Can you tell some details about the hardware / software that is experiencing this issue? If you are an Arm customer you may prefer to provide such details via a support case in Arm's support portal. If you do, can you please provide logs (gatord -d) and an export of the failing capture.

Please also try updating to the latest version of Streamline. Currently Streamline 7.8 is the latest version, and 7.9 is soon to be released.

Hi @bengaineyarm

Yes, we save file. it is a flat line. and i used printf in read func, it is troggle once.

Hi @haruzheng - all the configuration looks OK. One thing it could be was a bug we fixed for 7.8 that was affecting some other tracepoint counters, but its possible it is also affecting the CPU frequency counter...

Are you able to update to 7.8? Or alternatively, are you able to modify and rebuild gatord from source?

You can try pulling 7.8.0 tag from this repo and then modifying daemon/ProtocolVersion.h so that the version number is 770 instead of 780. This should allow you to use the later gatord with the older Streamline and pick up the fix.

[haruzheng]

Hi @bengaineyarm

I try clean 7.8, with change version to 770.
But it same. I alway no get CPU frequency.

I try to simpleperf, traceFS, ebpf tool.
In simpleperf

Samples: 0
Event count: 0

But traceFS, ebpf tool has value.
like

# cat /sys/kernel/debug/tracing/trace
sugov:0-1184  [002] .... 73119.468355: cpu_frequency: state=600000 cpu_id=0
sugov:0-1184  [002] .... 73119.468368: cpu_frequency: state=600000 cpu_id=1
sugov:0-1184  [002] .... 73119.468372: cpu_frequency: state=600000 cpu_id=2
sugov:0-1184  [002] .... 73119.468377: cpu_frequency: state=600000 cpu_id=3

[bengaineyarm]

So all those tools also fail with the same issue ? :-( that is odd.

Is it an Android device running recent Android version; is traced running? I wonder if there is some other ftrace based capture that is interfering with perf/gatord.

What is the output from cat /sys/kernel/debug/tracing/events/power/cpu_frequency/enable and cat /sys/kernel/debug/tracing/events/power/cpu_frequency/format ?

[haruzheng]

Perf and Simpleperf not counter value.
Device is Android R.

[haruzheng]

Maybe is user space not have permission with perf event?
Because not only cpu_frequency.
cpu_idle, and some event was not show in streamline.

[haruzheng]

Hi @bengaineyarm

i try to buildroot, i can get cpu_frequency counter in perf tool.
but using gator in buildroot same, can't get value in streamline.

i want to get perf event value in gator.
what should i do it?

[bengaineyarm]

So simpleperf did not work but perf does work in buildroot, and in both cases gatord does not?

How are you running perf tool? (what arguments are you giving it) ?

Can you run it in 'very verbose mode' (for example perf stat -vvv or perf record -vvv and show me the perf attribute description that it prints out that works.

[haruzheng]

I try ./perf stat -a -e power:* -- sleep 30 &

Hi @bengaineyarm

In buildroot, i change /proc/sys/kernel/perf_event_paranoid from 2 to -1.
It is work in buildroot with gator and streamline.
But but, switch to android r, using same linux kernel, it not working.
I think it maybe is Android R secure problem.

How do you think?

[bengaineyarm]

Hi @haruzheng - that is interesting. On Android, if you change perf_event_paranoid do you still see the problem? Gatord should modify that file (at least if you are running as root, but i think its worth to check).

It is certainly possible their is something in Android that we are not aware of that is blocking the event. We've only seen this one on one other device, but it was also Android (11).

Are you blocked by it not working on Android, or can you use Linux?

Is your kernel very customized or based on Android stock kernel? (I will try to figure out what might be blocking)

[haruzheng]

Hi @bengaineyarm

In Android 9 is work(gator 7.8), but gator 7.7 not work.
My kernel is base on android linux kernel, add our soc patch.

Maybe i can try to android 10.

I using root with gator.
In Android 11, i check perf_event_paranoid is -1, so i don;t know which config cause in android 11.

[bengaineyarm]

Ok, definitely use 7.8 if you can. I will look at the kernel source and see if can figure out the issue.

I have an alternative work around, which is to allow gatord to use ftrace api instead of perf api to collect this tracepoint, but that requires modifications to both gatord and Streamline so would not be available until the next Streamline release (which will be 8.0 because we have just completed the internal release of 7.9 )

[haruzheng]

You mean we need update streamline version?

Maybe I need with our team discuss.
I not sure my streamline licence can update to last version.

[bengaineyarm]

You mean we need update streamline version?

Yes; if we have to fix this by using ftrace instead of perf as it needs some post-processing, which is done by Streamline.

I not sure my streamline licence can update to last version.

Sure, IIRC most Arm DS licenses these days are time-limited rather than version-limited so hopefully you should be able to get the update. If not please raise the issue via the Arm DS support channel and we can see what we can do.

[haruzheng]

If i want to lookup this event value in gator 7.7, i can insert printf() in where?
I looking for away is long time, but i can't found it.

[bengaineyarm]

It would be difficult; the counter event comes from perf in its 'mmap' ring buffer as a PERF_RECORD_SAMPLE (see https://man.archlinux.org/man/perf_event_open.2 for general details). You'd have to modify PerfBuffer and parse the event records as they are extracted from the mmap into the gator sender buffer.

What are you trying to achieve?

[haruzheng]

I want to check gator7.7 can get this event value, like state and cpu_id.
Or just can't send to streamline?

Because I need to describe the gator 7.7 problem with my team member.

Thank you.

[bengaineyarm]

I understand. If its easier, you can raise a support case via https://support.developer.arm.com/my-cases/open-case/ and send the capture file to us and we can review it for you.

[bengaineyarm]

@haruzheng thats a great discovery; thanks for the update. I will update our documentation.
