From: Daniel Vetter Date: Thu, 26 Apr 2012 21:28:05 +0000 (+0200) Subject: drm/i915: remove LP_RING&friends from modeset code X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=6d90c952cdd20158ec41a5c016c6fad73c9a8749;p=linux-beck.git drm/i915: remove LP_RING&friends from modeset code The LP refers to 'low priority' as opposed to the high priority ring on gen2/3. So lets constrain its use to the code of that era. Unfortunately we can't yet completely remove the associated macros from common headers and shove them into i915_dma.c to the other dri1 legacy support code, a few cleanups are still missing for that.
