From a73ae3d5eb8419feab5aea26573aa41b72f941eb Mon Sep 17 00:00:00 2001 From: Keith Whitwell Date: Fri, 2 May 2008 16:46:31 +0100 Subject: gallium: Add texture usage flags, special-case allocation of display targets For many envirionments it's necessary to allocate display targets in a window-system friendly manner. Add facilities so that a driver can tell if a texture is likely to be used to generate a display surface and if use special allocation paths if necessary. Hook up softpipe to call into the winsys->surface_alloc_storage() routine in this case, though we probably want to change that interface slightly also. --- src/mesa/state_tracker/st_atom_pixeltransfer.c | 3 ++- 1 file changed, 2 insertions(+), 1 deletion(-) (limited to 'src/mesa/state_tracker/st_atom_pixeltransfer.c') diff --git a/src/mesa/state_tracker/st_atom_pixeltransfer.c b/src/mesa/state_tracker/st_atom_pixeltransfer.c index 0c32d53c4a..e500ac8684 100644 --- a/src/mesa/state_tracker/st_atom_pixeltransfer.c +++ b/src/mesa/state_tracker/st_atom_pixeltransfer.c @@ -126,7 +126,8 @@ create_color_map_texture(GLcontext *ctx) /* create texture for color map/table */ pt = st_texture_create(ctx->st, PIPE_TEXTURE_2D, format, 0, - texSize, texSize, 1, 0); + texSize, texSize, 1, 0, + PIPE_TEXTURE_USAGE_SAMPLER); return pt; } -- cgit v1.2.3
