| H A D | i915_irq.c | diff bbb5eebf034be22fb4de6e9879a0933d3292cf2f Wed Feb 12 10:55:36 CST 2014 Daniel Vetter <daniel.vetter@ffwll.ch> drm/i915: Some polish for the new pipestat_irq_handler
Just a bit of polish which I hope will help me with massaging some
internal patches to use Imre's reworked pipestat handling:
- Don't check for underrun reporting or enable pipestat interrupts
twice.
- Frob the comments a bit.
- Do the iir PIPE_EVENT to pipe mapping explicitly with a switch. We
only have one place which does this, so better to make it explicit.
v2: Ville noticed that I've broken the logic a bit with trying to
avoid checking whether we're interested in a given pipe twice. push
the PIPESTAT read down after we've computed the mask of interesting
bits first to avoid that duplication properly.
v3: Squash in fixups from Imre on irc.
