From 753a4bdf1b554490f7b288c0203050b5114433c3 Mon Sep 17 00:00:00 2001 From: Dave Airlie Date: Sun, 30 Mar 2008 07:33:39 +1000 Subject: drm/r300: fix wait interface mixup This interface was defined completely wrong, however userspace has only ever used 4 values from it (0x1, 0x2, 0x3 and 0x6), so fix the interface to do what userspace actually expected but define new defines for new users to use it properly. --- shared-core/radeon_drm.h | 12 ++++++++++++ 1 file changed, 12 insertions(+) (limited to 'shared-core/radeon_drm.h') diff --git a/shared-core/radeon_drm.h b/shared-core/radeon_drm.h index c4d9cc6b..67c35585 100644 --- a/shared-core/radeon_drm.h +++ b/shared-core/radeon_drm.h @@ -225,8 +225,20 @@ typedef union { #define R300_CMD_WAIT 7 # define R300_WAIT_2D 0x1 # define R300_WAIT_3D 0x2 +/* these two defines are DOING IT WRONG - however + * we have userspace which relies on using these. + * The wait interface is backwards compat new + * code should use the NEW_WAIT defines below + * THESE ARE NOT BIT FIELDS + */ # define R300_WAIT_2D_CLEAN 0x3 # define R300_WAIT_3D_CLEAN 0x4 + +# define R300_NEW_WAIT_2D_3D 0x3 +# define R300_NEW_WAIT_2D_2D_CLEAN 0x4 +# define R300_NEW_WAIT_3D_3D_CLEAN 0x6 +# define R300_NEW_WAIT_2D_2D_CLEAN_3D_3D_CLEAN 0x8 + #define R300_CMD_SCRATCH 8 #define R300_CMD_R500FP 9 -- cgit v1.2.3
