	help
	  Choose this option to enable tracepoints for tracking
	  global and per-process GPU memory usage. Intended for
	  performance profiling and required for Android.

	  Tracepoint availability varies by GPU driver.

	  If in doubt, say "N".
gpu/trace: add a gpu total memory usage tracepoint This change adds the below gpu memory tracepoint: gpu_mem/gpu_mem_total: track global or proc gpu memory total usages Per process tracking of total gpu memory usage in the gem layer is not appropriate and hard to implement with trivial overhead. So for the gfx device driver layer to track total gpu memory usage both globally and per process in an easy and uniform way is to integrate the tracepoint in this patch to the underlying varied implementations of gpu memory tracking system from vendors. Putting this tracepoint in the common trace events can not only help wean the gfx drivers off of debugfs but also greatly help the downstream Android gpu vendors because debugfs is to be deprecated in the upcoming Android release. Then the gpu memory tracking of both Android kernel and the upstream linux kernel can stay closely, which can benefit the whole kernel eco-system in the long term.
