From 164dc6216a8e4d46ef7db9f54bcecd58ff556b83 Mon Sep 17 00:00:00 2001 From: Marek Olšák Date: Wed, 4 Dec 2013 00:56:24 +0100 Subject: gallium: allow choosing which colorbuffers to clear Required for glClearBuffer, which only clears one colorbuffer attachment. Example: If the first colorbuffer is float and the second one is int: pipe->clear(pipe, PIPE_CLEAR_COLOR0, float_clear_color, ...); pipe->clear(pipe, PIPE_CLEAR_COLOR1, int_clear_color, ...); This doesn't need any driver changes yet, because all drivers just use: if (flags & PIPE_CLEAR_COLOR) .. The drivers which support GL 3.0 will have to implement it properly though. --- src/gallium/include/pipe/p_defines.h | 19 +++++++++++++++---- 1 file changed, 15 insertions(+), 4 deletions(-) (limited to 'src/gallium/include/pipe/p_defines.h') diff --git a/src/gallium/include/pipe/p_defines.h b/src/gallium/include/pipe/p_defines.h index 06a9edd2714..982f52969cf 100644 --- a/src/gallium/include/pipe/p_defines.h +++ b/src/gallium/include/pipe/p_defines.h @@ -188,11 +188,22 @@ enum pipe_texture_target { /** * Clear buffer bits */ +#define PIPE_CLEAR_DEPTH (1 << 0) +#define PIPE_CLEAR_STENCIL (1 << 1) +#define PIPE_CLEAR_COLOR0 (1 << 2) +#define PIPE_CLEAR_COLOR1 (1 << 3) +#define PIPE_CLEAR_COLOR2 (1 << 4) +#define PIPE_CLEAR_COLOR3 (1 << 5) +#define PIPE_CLEAR_COLOR4 (1 << 6) +#define PIPE_CLEAR_COLOR5 (1 << 7) +#define PIPE_CLEAR_COLOR6 (1 << 8) +#define PIPE_CLEAR_COLOR7 (1 << 9) +/** Combined flags */ /** All color buffers currently bound */ -#define PIPE_CLEAR_COLOR (1 << 0) -#define PIPE_CLEAR_DEPTH (1 << 1) -#define PIPE_CLEAR_STENCIL (1 << 2) -/** Depth/stencil combined */ +#define PIPE_CLEAR_COLOR (PIPE_CLEAR_COLOR0 | PIPE_CLEAR_COLOR1 | \ + PIPE_CLEAR_COLOR2 | PIPE_CLEAR_COLOR3 | \ + PIPE_CLEAR_COLOR4 | PIPE_CLEAR_COLOR5 | \ + PIPE_CLEAR_COLOR6 | PIPE_CLEAR_COLOR7) #define PIPE_CLEAR_DEPTHSTENCIL (PIPE_CLEAR_DEPTH | PIPE_CLEAR_STENCIL) /** -- cgit v1.2.3
