From 94ce4eb3c27706d992226d847d123c46b14b1c4f Mon Sep 17 00:00:00 2001 From: Keith Whitwell Date: Thu, 4 Mar 2010 16:09:33 +0000 Subject: softpipe: rework to use the llvmpipe winsys Promote the llvmpipe winsys more or less unchanged to state_trackers/sw_winsys.h. Some minor breakages: - softpipe::texture_blanket is broken, but scheduled for removal anyway. - haven't fixed up g3vdl yet. --- src/gallium/drivers/llvmpipe/lp_screen.c | 8 +- src/gallium/drivers/llvmpipe/lp_screen.h | 4 +- src/gallium/drivers/llvmpipe/lp_setup.c | 2 +- src/gallium/drivers/llvmpipe/lp_texture.c | 8 +- src/gallium/drivers/llvmpipe/lp_texture.h | 5 +- src/gallium/drivers/llvmpipe/lp_winsys.h | 125 ------- src/gallium/drivers/softpipe/Makefile | 4 +- src/gallium/drivers/softpipe/SConscript | 4 +- src/gallium/drivers/softpipe/sp_buffer.c | 118 +++++++ src/gallium/drivers/softpipe/sp_buffer.h | 55 +++ src/gallium/drivers/softpipe/sp_context.c | 2 +- src/gallium/drivers/softpipe/sp_draw_arrays.c | 96 +----- src/gallium/drivers/softpipe/sp_screen.c | 43 ++- src/gallium/drivers/softpipe/sp_screen.h | 12 + src/gallium/drivers/softpipe/sp_state_fs.c | 20 +- src/gallium/drivers/softpipe/sp_texture.c | 115 +++---- src/gallium/drivers/softpipe/sp_texture.h | 11 +- src/gallium/drivers/softpipe/sp_winsys.c | 245 -------------- src/gallium/drivers/softpipe/sp_winsys.h | 73 ---- src/gallium/include/state_tracker/sw_winsys.h | 121 +++++++ src/gallium/winsys/gdi/SConscript | 2 +- src/gallium/winsys/gdi/gdi_llvmpipe_winsys.c | 157 +-------- src/gallium/winsys/gdi/gdi_softpipe_winsys.c | 239 ++----------- src/gallium/winsys/xlib/Makefile | 1 + src/gallium/winsys/xlib/SConscript | 4 +- src/gallium/winsys/xlib/xlib.c | 4 +- src/gallium/winsys/xlib/xlib.h | 7 + src/gallium/winsys/xlib/xlib_llvmpipe.c | 363 +------------------- src/gallium/winsys/xlib/xlib_softpipe.c | 464 +------------------------- src/gallium/winsys/xlib/xlib_sw_winsys.c | 394 ++++++++++++++++++++++ 30 files changed, 897 insertions(+), 1809 deletions(-) delete mode 100644 src/gallium/drivers/llvmpipe/lp_winsys.h create mode 100644 src/gallium/drivers/softpipe/sp_buffer.c create mode 100644 src/gallium/drivers/softpipe/sp_buffer.h delete mode 100644 src/gallium/drivers/softpipe/sp_winsys.c delete mode 100644 src/gallium/drivers/softpipe/sp_winsys.h create mode 100644 src/gallium/include/state_tracker/sw_winsys.h create mode 100644 src/gallium/winsys/xlib/xlib_sw_winsys.c (limited to 'src/gallium') diff --git a/src/gallium/drivers/llvmpipe/lp_screen.c b/src/gallium/drivers/llvmpipe/lp_screen.c index f84ede675b3..8816440a509 100644 --- a/src/gallium/drivers/llvmpipe/lp_screen.c +++ b/src/gallium/drivers/llvmpipe/lp_screen.c @@ -167,7 +167,7 @@ llvmpipe_is_format_supported( struct pipe_screen *_screen, unsigned geom_flags ) { struct llvmpipe_screen *screen = llvmpipe_screen(_screen);
