From: Keith Whitwell Date: Sun, 28 Mar 2010 16:53:58 +0000 (-0700) Subject: gallium: new raw gallium interface to support standalone tests X-Git-Tag: 062012170305~13794 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=db5c2235d1accc2adcf1746aec2342bfa67237ba;p=profile%2Fivi%2Fmesa.git gallium: new raw gallium interface to support standalone tests Provides basic window system integration behind a simple interface, allowing tests to be written without dependency on either the driver or window system. With a lot of work, could turn into something like glut for gallium. --- diff --git a/SConstruct b/SConstruct index 2549a13..5d44b6e 100644 --- a/SConstruct +++ b/SConstruct @@ -52,7 +52,7 @@ opts.Add(ListVariable('statetrackers', 'state trackers to build', default_statet opts.Add(ListVariable('drivers', 'pipe drivers to build', default_drivers, ['softpipe', 'failover', 'svga', 'i915', 'i965', 'trace', 'r300', 'identity', 'llvmpipe'])) opts.Add(ListVariable('winsys', 'winsys drivers to build', default_winsys, - ['xlib', 'vmware', 'i915', 'i965', 'gdi', 'radeon'])) + ['xlib', 'vmware', 'i915', 'i965', 'gdi', 'radeon', 'graw-xlib'])) opts.Add(EnumVariable('MSVS_VERSION', 'MS Visual C++ version', None, allowed_values=('7.1', '8.0', '9.0'))) diff --git a/progs/SConscript b/progs/SConscript index aa6640c..20be609 100644 --- a/progs/SConscript +++ b/progs/SConscript @@ -56,4 +56,5 @@ SConscript([ 'wgl/SConscript', 'perf/SConscript', 'gallium/unit/SConscript', + 'gallium/raw/SConscript', ]) diff --git a/progs/gallium/raw/SConscript b/progs/gallium/raw/SConscript new file mode 100644 index 0000000..073b979 --- /dev/null +++ b/progs/gallium/raw/SConscript @@ -0,0 +1,17 @@ +Import('*') + +env = env.Clone() + +env.Prepend(LIBPATH = [graw.dir]) +env.Prepend(LIBS = [graw.name]) + +progs = [ + 'clear' +] + +for prog in progs: + env.Program( + target = prog, + source = prog + '.c', + ) + diff --git a/progs/gallium/raw/clear.c b/progs/gallium/raw/clear.c new file mode 100644 index 0000000..e46d135 --- /dev/null +++ b/progs/gallium/raw/clear.c @@ -0,0 +1,85 @@ +/* Display a cleared blue window.
