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/auxiliary/util/u_timed_winsys.c | 45 ++---------- src/gallium/drivers/i915simple/i915_texture.c | 1 - src/gallium/drivers/i965simple/brw_tex_layout.c | 7 +- src/gallium/drivers/nv04/nv04_miptree.c | 6 +- src/gallium/drivers/nv10/nv10_miptree.c | 4 +- src/gallium/drivers/nv20/nv20_miptree.c | 1 - src/gallium/drivers/nv30/nv30_miptree.c | 1 - src/gallium/drivers/nv40/nv40_miptree.c | 1 - src/gallium/drivers/nv50/nv50_miptree.c | 15 ++-- src/gallium/drivers/softpipe/sp_texture.c | 43 +++--------- src/gallium/drivers/softpipe/sp_texture.h | 2 +- src/gallium/drivers/trace/tr_texture.c | 1 - src/gallium/drivers/trace/tr_winsys.c | 81 +++++----------------- src/gallium/include/pipe/p_inlines.h | 44 ++++-------- src/gallium/include/pipe/p_state.h | 4 +- src/gallium/include/pipe/p_winsys.h | 36 +++++----- .../state_trackers/python/st_softpipe_winsys.c | 70 ++++--------------- .../winsys/drm/intel/common/intel_be_device.c | 46 +++++------- src/gallium/winsys/egl_xlib/sw_winsys.c | 70 ++++--------------- .../winsys/g3dvl/nouveau/nouveau_winsys_pipe.c | 35 ++++------ src/gallium/winsys/g3dvl/xsp_winsys.c | 67 ++++-------------- src/gallium/winsys/gdi/gdi_softpipe_winsys.c | 68 ++++-------------- 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 +++++---------------- 25 files changed, 217 insertions(+), 654 deletions(-) (limited to 'src') diff --git a/src/gallium/auxiliary/util/u_timed_winsys.c b/src/gallium/auxiliary/util/u_timed_winsys.c index 8beb3b4c885..dc3c9be5952 100644 --- a/src/gallium/auxiliary/util/u_timed_winsys.c +++ b/src/gallium/auxiliary/util/u_timed_winsys.c @@ -205,34 +205,18 @@ timed_flush_frontbuffer( struct pipe_winsys *winsys, -static struct pipe_surface * -timed_surface_alloc(struct pipe_winsys *winsys) -{ - struct pipe_winsys *backend = timed_winsys(winsys)->backend;
