[Intel-gfx] [PATCH 09/10] drm/i915: Split i915_dem_do_execbuffer() in half
John.C.Harrison at Intel.com
John.C.Harrison at Intel.com
Tue Dec 9 04:59:12 PST 2014
From: John Harrison <John.C.Harrison at Intel.com>
Split the execbuffer() function in half. The first half collects and validates
all the information requried to process the batch buffer. It also does all the
object pinning, relocations, active list management, etc - basically anything
that must be done upfront before the IOCTL returns and allows the user land side
to start changing/freeing things. The second half does the actual ring
submission.
This change implements the split but leaves the back half being called directly
from the end of the front half.
Change-Id: I5e1c77639ce526ab2401b0323186c518bf13da0a
For: VIZ-1587
