[Intel-gfx] [RFC v2 0/3] drm/i915: Trace point callbacks for kernel validation

[daniele.ceraolospurio at intel.com]

From: Daniele Ceraolo Spurio <daniele.ceraolospurio at intel.com>

The callbacks are useful for validation because they can be used to extract 
real-time information from the kernel.

v2: duplicate the i915_gem_ring_dispatch trace instead of modifying the 
existing one.

I plan to resubmit these patches together with an igt test and a kernel module
that uses the callbacks (as requested), but before doing that I wanted to be 
sure that I've correctly addressed all the comments.

Daniele Ceraolo Spurio (3):
  drm/i915: Add ppgtt init/release trace points
  drm/i915: duplicate i915_gem_ring_dispatch trace and add ctx parameter
  drm/i915: Trace point callbacks for validation
