看上去是权限问题，可能需要root权限

[a243845305]

我应该已经获取了root 权限
adb root
-> adbd is already running as root
adb remount
-> remount succeeded
chmod 777 gpu_adreno_pmu_test
./gpu_adreno_pmu_test 100 10 10

仍然是这样的信息。
是上述获取root权限的方式有误？还是其他什么问题呢？

啊， 是我看错了，你这是要在adreno730上采样呀，当前只支持adreno6xx系列的adreno，adreno7xx的pmu event list在开源世界里找不到，没法加支持

哦哦，好，期待后续更新。
另外问下 mali 有类似最高支持的版本吗？
