drm/i915: DocBook integration for frontbuffer tracking
I shouldn't ask everyone to do this and fail myself ... This extracts all the frontbuffer tracking functions into intel_frontbuffer.c, adds a DOC overview section and also adds the missing kerneldoc for i915_gem_track_fb and also pulls it into the same section for convenience. v2: Don't forget about the header files. v3: Oops, might check compilation next time around. To make my life easier drop the increase_pllclock from set_base_atomic since really, it doesn't matter if you see your Oops or kgdb with a tiny bit of lag. v4: Try to better explain how to actually use this, requested by Paulo on irc. v5: Explain invalidate/flush a bit clearer. v6: s/business/busyness/ Acked-by: Paulo Zanoni <paulo.r.zanoni@intel.com> Cc: Paulo Zanoni <paulo.r.zanoni@intel.com> Cc: Vandana Kannan <vandana.kannan@intel.com> Signed-off-by: Daniel Vetter <daniel.vetter@intel.com>
