From 25c51f539f254937d116699e66f8c382d78e71d4 Mon Sep 17 00:00:00 2001 From: Dave Airlie Date: Tue, 8 May 2007 17:53:58 +1000 Subject: drm/ttm: ioctl cleanup for buffer object - user side only This just cleans up the xf86drm.c to what I want and drm.h, I need to fix up the kernel internals to suit these changes now. I've moved to using struct instead of typedefs for the bo and it doesn't look that bad so I'll do the same thing for mm and fence.. --- libdrm/xf86drm.c | 185 +++++++++++++++++++------------------------------------ libdrm/xf86mm.h | 2 +- 2 files changed, 66 insertions(+), 121 deletions(-) (limited to 'libdrm') diff --git a/libdrm/xf86drm.c b/libdrm/xf86drm.c index b53fe2fb..63b9354f 100644 --- a/libdrm/xf86drm.c +++ b/libdrm/xf86drm.c @@ -2598,7 +2598,7 @@ int drmBOCreateList(int numTarget, drmBOList *list) return drmAdjustListNodes(list);
