From: Michel Dänzer Date: Tue, 7 Jul 2009 12:49:52 +0000 (+0200) Subject: gallium: Fixes for clobbering stencil values in combined depth/stencil textures. X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=71633abafc935c25da9731bab48c228ceb9b4097;p=mesa.git gallium: Fixes for clobbering stencil values in combined depth/stencil textures. Also fix one case where a 32 bit depth value was incorrectly converted to a combined depth/stencil value. --- diff --git a/src/gallium/auxiliary/util/u_tile.c b/src/gallium/auxiliary/util/u_tile.c index 9747a55cbfa..a0c8ed88f74 100644 --- a/src/gallium/auxiliary/util/u_tile.c +++ b/src/gallium/auxiliary/util/u_tile.c @@ -1202,6 +1202,19 @@ pipe_put_tile_z(struct pipe_transfer *pt, } break;
