From cc64606a535edd9fd96487631f8ef583226fc575 Mon Sep 17 00:00:00 2001 From: Sunny He Date: Wed, 21 Jun 2017 12:08:08 -0700 Subject: gpu: nvgpu: debugfs code to dump HAL functions Prints addresses of device-specific HAL functions to debugfs file hal/gops. The list of functions is produced by dumping the contents of the gpu_ops substruct of the gk20a struct. This interface makes the assumption that there are only function pointers in gpu_ops. Companion Python script nvgpu_debug_hal.py analyzes gk20a.h to determine operation counts and prettyify debugfs interface's output.
