From 0dab3189e1d100a9a2487f7aff45589b423c386c Mon Sep 17 00:00:00 2001 From: Dave Airlie Date: Sun, 21 Mar 2010 18:23:22 +1000 Subject: [PATCH] gallium: cached bufmgr add map busy check Suggested by Jose on the list, probably not perfect but will let me get past this for now, testing with a fenced bufmgr on top of this, was slower, Also this doesn't let you do the busy early exit optimisation either from what I can see.
