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_cb_texture.c | 10 ++++++++-- 1 file changed, 8 insertions(+), 2 deletions(-) (limited to 'src/mesa/state_tracker/st_cb_texture.c') diff --git a/src/mesa/state_tracker/st_cb_texture.c b/src/mesa/state_tracker/st_cb_texture.c index 4cca3364c1..06caa06e77 100644 --- a/src/mesa/state_tracker/st_cb_texture.c +++ b/src/mesa/state_tracker/st_cb_texture.c @@ -333,7 +333,9 @@ guess_and_alloc_texture(struct st_context *st, width, height, depth, - comp_byte); + comp_byte, + ( PIPE_TEXTURE_USAGE_RENDER_TARGET | + PIPE_TEXTURE_USAGE_SAMPLER )); DBG("%s - success\n", __FUNCTION__); } @@ -1501,7 +1503,11 @@ st_finalize_texture(GLcontext *ctx, firstImage->base.Width2, firstImage->base.Height2, firstImage->base.Depth2, - comp_byte); + comp_byte, + + ( PIPE_TEXTURE_USAGE_RENDER_TARGET | + PIPE_TEXTURE_USAGE_SAMPLER )); + if (!stObj->pt) { _mesa_error(ctx, GL_OUT_OF_MEMORY, "glTexImage"); return GL_FALSE; -- cgit v1.2.3
