From 5897383344da3320d158c26adae05de35480471f Mon Sep 17 00:00:00 2001 From: José Fonseca Date: Tue, 20 Jan 2009 12:22:49 +0000 Subject: gallium: Remove the standalone surfaces. This commit is mostly just a cosmetic change that cleans-up the interfaces, replacing pipe_winsys::surface_* calls by /** * Allocate storage for a display target surface. * * Often surfaces which are meant to be blitted to the front screen (i.e., * display targets) must be allocated with special characteristics, memory * pools, or obtained directly from the windowing system. * * This callback is invoked by the pipe_screenwhen creating a texture marked * with the PIPE_TEXTURE_USAGE_DISPLAY_TARGET flag to get the underlying * buffer storage. */ struct pipe_buffer *(*surface_buffer_create)(struct pipe_winsys *ws, unsigned width, unsigned height, enum pipe_format format, unsigned usage, unsigned *stride); Most drivers were updated but not all were tested. Use the softpipe pipe driver and the xlib winsys changes as a reference when fixing other drivers. --- src/gallium/winsys/xlib/xlib_brw_screen.c | 63 ++++++------------------ src/gallium/winsys/xlib/xlib_cell.c | 80 +++++++------------------------ src/gallium/winsys/xlib/xlib_softpipe.c | 80 +++++++------------------------ 3 files changed, 50 insertions(+), 173 deletions(-) (limited to 'src/gallium/winsys/xlib') diff --git a/src/gallium/winsys/xlib/xlib_brw_screen.c b/src/gallium/winsys/xlib/xlib_brw_screen.c index 030cd66bd9..1fd7da8a2f 100644 --- a/src/gallium/winsys/xlib/xlib_brw_screen.c +++ b/src/gallium/winsys/xlib/xlib_brw_screen.c @@ -229,17 +229,6 @@ aub_flush_frontbuffer( struct pipe_winsys *winsys, aub_bo(surface->buffer)->offset );
