From 0521c2682a3249562ff6a3d6ab6c90d1d63b82a3 Mon Sep 17 00:00:00 2001 From: Younes Manton Date: Wed, 14 Jan 2009 00:21:24 -0500 Subject: gallium: Add PIPE_BUFFER_USAGE_DISCARD. When passed to map() signals that the buffer's previous contents are not required, allowing the driver to allocate a new buffer if the current buffer can not be mapped immediately. --- src/gallium/include/pipe/p_defines.h | 1 + 1 file changed, 1 insertion(+) (limited to 'src/gallium') diff --git a/src/gallium/include/pipe/p_defines.h b/src/gallium/include/pipe/p_defines.h index 5c6a92b53b..4f0b301f31 100644 --- a/src/gallium/include/pipe/p_defines.h +++ b/src/gallium/include/pipe/p_defines.h @@ -204,6 +204,7 @@ enum pipe_texture_target { #define PIPE_BUFFER_USAGE_VERTEX (1 << 5) #define PIPE_BUFFER_USAGE_INDEX (1 << 6) #define PIPE_BUFFER_USAGE_CONSTANT (1 << 7) +#define PIPE_BUFFER_USAGE_DISCARD (1 << 8) /** Pipe driver custom usage flags should be greater or equal to this value */ #define PIPE_BUFFER_USAGE_CUSTOM (1 << 16) -- cgit v1.2.3
