hardware-perfcounter's Issues

how much data could get in one ioctl_counter?

I follow the example to create the counters array to query some data.
I found the data is inconsistant each counter with different order。
eg. I create the counter item like this
`hpc_gpu_adreno_common_counter_t counters[] = {
HPC_GPU_ADRENO_COMMON_CP_BUSY_GFX_CORE_IDLE,
HPC_GPU_ADRENO_COMMON_CP_BUSY_CYCLES,

  HPC_GPU_ADRENO_COMMON_TP_L1_CACHELINE_REQUESTS,
  HPC_GPU_ADRENO_COMMON_TP_L1_CACHELINE_MISSES,

  HPC_GPU_ADRENO_COMMON_TP_OUTPUT_PIXELS_POINT,
  HPC_GPU_ADRENO_COMMON_TP_OUTPUT_PIXELS_BILINEAR,
  HPC_GPU_ADRENO_COMMON_TP_OUTPUT_PIXELS_MIP,
  HPC_GPU_ADRENO_COMMON_TP_OUTPUT_PIXELS_ANISO,
  HPC_GPU_ADRENO_COMMON_TP_OUTPUT_PIXELS_ZERO_LOD,

  HPC_GPU_ADRENO_COMMON_PC_VERTEX_HITS,
  HPC_GPU_ADRENO_COMMON_PC_NON_DRAWCALL_GLOBAL_EVENTS,

};`

And I got the result of counter data as the data1.
Then I change the counter item like:
`hpc_gpu_adreno_common_counter_t counters[] = {
HPC_GPU_ADRENO_COMMON_PC_VERTEX_HITS,
HPC_GPU_ADRENO_COMMON_PC_NON_DRAWCALL_GLOBAL_EVENTS,

  HPC_GPU_ADRENO_COMMON_CP_BUSY_GFX_CORE_IDLE,
  HPC_GPU_ADRENO_COMMON_CP_BUSY_CYCLES,

  HPC_GPU_ADRENO_COMMON_TP_L1_CACHELINE_REQUESTS,
  HPC_GPU_ADRENO_COMMON_TP_L1_CACHELINE_MISSES,

  HPC_GPU_ADRENO_COMMON_TP_OUTPUT_PIXELS_POINT,
  HPC_GPU_ADRENO_COMMON_TP_OUTPUT_PIXELS_BILINEAR,
  HPC_GPU_ADRENO_COMMON_TP_OUTPUT_PIXELS_MIP,
  HPC_GPU_ADRENO_COMMON_TP_OUTPUT_PIXELS_ANISO,
  HPC_GPU_ADRENO_COMMON_TP_OUTPUT_PIXELS_ZERO_LOD,    

};`
We got the result of counter data as the data2.
It is apperantly that the last two item is move to the first. In the same phone and the same scene, I got total different magnitudes data with the vertex_hit and non_dracall_global_event compared with data1.

I'm wondering if there is something limit with the size of counter item in one ioctl counter?

ninja build error .What is missing?

ninja: error: '../third_party/envytools/registers/adreno/a5xx.xml', needed by '../lib/gpu/adreno/a5xx.c', missing and no known rule to make it

Could you make readme more specificly ?
e.g NDK version ; targetSDK version , c/c++ specific Compiler and version , ninjia version . Thanks .

Where can I find the description about the adreno’s counters?

I want to collect performance datas which are the same as SnapDragon profiler. But I can't find any information about the counters which this project collects at Qcom Websites, and the counters are different from Snapdragon profiler.

Could you give me some suggestions? Thanks a lot.
