[PATCH 21/55] drm/i915: Update do_switch() to take a request structure

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: John Harrison <John.C.Harrison@xxxxxxxxx>

Updated do_switch() to take a request pointer instead of a ring/context pair.

v2: Removed some overzealous req-> dereferencing.

For: VIZ-5115
