[Intel-gfx] [PATCH 5/8] drm/i915: Make execlist port count variable

2017-09-20 Thread Mika Kuoppala
As we emulate execlists on top of the GuC workqueue, it is not restricted to just 2 ports and we can increase that number arbitrarily to trade-off queue depth (i.e. scheduling latency) against pipeline bubbles. v2: rebase. better commit msg (Chris) Signed-off-by: Mika Kuoppala
