From: Eric Anholt Date: Mon, 19 May 2008 22:42:00 +0000 (-0700) Subject: Add back a mostly-correct glFinish for GEM and fake. X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=6cefae5354fb3015c5a14677071871613faa9c3a;p=mesa.git Add back a mostly-correct glFinish for GEM and fake. The right solution would probably be keeping a list of regions which have been rendered to. --- diff --git a/src/mesa/drivers/dri/common/dri_bufmgr.c b/src/mesa/drivers/dri/common/dri_bufmgr.c index 19ea2a8f86d..be2a7b740c3 100644 --- a/src/mesa/drivers/dri/common/dri_bufmgr.c +++ b/src/mesa/drivers/dri/common/dri_bufmgr.c @@ -127,6 +127,12 @@ dri_bo_get_subdata(dri_bo *bo, unsigned long offset, return 0;
