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/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 ++++++++++++++++++++++++++ 7 files changed, 428 insertions(+), 809 deletions(-) create mode 100644 src/gallium/winsys/xlib/xlib_sw_winsys.c (limited to 'src/gallium/winsys/xlib') diff --git a/src/gallium/winsys/xlib/Makefile b/src/gallium/winsys/xlib/Makefile index 824c666ae30..129300423a6 100644 --- a/src/gallium/winsys/xlib/Makefile +++ b/src/gallium/winsys/xlib/Makefile @@ -29,6 +29,7 @@ DEFINES += \ XLIB_WINSYS_SOURCES = \ xlib.c \ xlib_cell.c \ + xlib_sw_winsys.c \ xlib_llvmpipe.c \ xlib_softpipe.c diff --git a/src/gallium/winsys/xlib/SConscript b/src/gallium/winsys/xlib/SConscript index 8c9d318af2b..92e508ee50c 100644 --- a/src/gallium/winsys/xlib/SConscript +++ b/src/gallium/winsys/xlib/SConscript @@ -36,7 +36,7 @@ drivers = [trace] if 'softpipe' in env['drivers']: env.Append(CPPDEFINES = 'GALLIUM_SOFTPIPE') - sources += ['xlib_softpipe.c'] + sources += ['xlib_softpipe.c', 'xlib_sw_winsys.c'] drivers += [softpipe] if 'llvmpipe' in env['drivers']: @@ -44,7 +44,7 @@ if 'llvmpipe' in env['drivers']: if 'LLVM_VERSION' in env: env.Append(CPPDEFINES = 'GALLIUM_LLVMPIPE') env.Tool('udis86') - sources += ['xlib_llvmpipe.c'] + sources += ['xlib_llvmpipe.c', 'xlib_sw_winsys.c'] drivers += [llvmpipe] if 'cell' in env['drivers']: diff --git a/src/gallium/winsys/xlib/xlib.c b/src/gallium/winsys/xlib/xlib.c index 67617a470d6..9b91c980d15 100644 --- a/src/gallium/winsys/xlib/xlib.c +++ b/src/gallium/winsys/xlib/xlib.c @@ -33,9 +33,7 @@ #include "xlib.h" #include "xm_winsys.h" - -#include -#include +#include "util/u_debug.h" /* Todo, replace all this with callback-structs provided by the * individual implementations. diff --git a/src/gallium/winsys/xlib/xlib.h b/src/gallium/winsys/xlib/xlib.h index 8e091d0c084..7f9f910b88d 100644 --- a/src/gallium/winsys/xlib/xlib.h +++ b/src/gallium/winsys/xlib/xlib.h @@ -9,5 +9,12 @@ extern struct xm_driver xlib_softpipe_driver;
