Handheld device implementations:

+ supports the GPU profiling capability via a system property
+ `graphics.gpu.profiler.support`.

+* [[7.1](#7_1_display_and_graphics).4.6/H-1-1] MUST report as output a

+ renderstages defined in the [Perfetto documentation](https://developer.android.com/studio/command-line/perfetto).
+* [[7.1](#7_1_display_and_graphics).4.6/H-1-2] MUST report conformant values
+ for the device’s GPU counters following the
+ [gpu counter trace packet proto](https://android.googlesource.com/platform/external/perfetto/+/refs/heads/master/protos/perfetto/trace/gpu/gpu_counter_event.proto).
