I have build gator and using arm streamline but it is unable to capture GPU events . Is there any specific way to build gator for Mali GPU G52 ?

[Omkar-Shende-212011004]

And there are some warnings:

1.Mali GPU counters

Successfully probed Mali device /dev/mali0 as Mali-G52 (0x7212 r0p0), 1 L2 Slices, 128-bit Bus, 2 Shader Cores.

Mali GPU counters

GPU frequency counters not available for GPU # 0.

No Perf PMUs detected

Could not detect any Perf PMUs in /sys/bus/event_source/devices/ but the system contains recognised CPUs. The system may not support perf hardware counters. Check CONFIG_HW_PERF_EVENTS is set and that the PMU is configured in the target device tree.

Mali: MMU page fault insert pages is disabled

/sys/kernel/tracing/events/mali/mali_page_fault_insert_pages/id was not found

You should not need to build gatord; pre-built binaries are provided that will work with Mali GPU.

It looks like the GPU was detected. What issue where you receiving?

Hi @bengaineyarm

I have similar problem.

In gator daemon debug message:

• Setup stage
  • Successfully probed Mali device /dev/mali0 as Mali-G57 (0x9091 r0p1), 1 L2 Slices, 128-bit Bus, 1 Shader Cores.
  • GPU frequency counters not available for GPU # 0.
• Start capture
  • MaliDeviceApi: Failed sending hwcnt reader ioctl.

My env:

• Android
• mali_kbase version r44p1-01eac0
• gator daemon v7.7

But If i using r42p0-01eac0 in my env, It is working. Thank you
