The llvm wrapper wasn't really an OS thing.
Use lp_bld.h for now but we eventually should rename/re-prefix all the
files/functions in the gallivm/ directory.
gallivm: add min_lod==max_lod special-case code in lp_build_lod_selector()
When min_lod==max_lod we don't need to go through all the work of
computing the lod from partial derivatives. This is hit by the mipmap
generation utility code.
LLVMBuildFPTrunc() should be used for double->float conversion, not
float->int conversion.
There should be a better way to compute floor(), ceil(), etc that doesn't
involve float->int->float conversion.
This creates a cleaner winsys and drop the simple screen stuff.
It makes r300g use pb_bufmgr structs.
It also tries to avoid overheads from mapping too often.
v5: clean warnings
v6: break out of cache check on first buffer - since most likely
the first busy one implies all after it are busy.
v7: cleanup a bit
v8-merged: drop cman for now to just get all the interface changes in first.
rework to changes that happened upstream
Signed-off-by: Dave Airlie <airlied@redhat.com>
src_native_swz was used to translate 0/1 swizzles back when Gallium
supported them.
That support was later removed from Gallium, and the function currently
always returns true.
Remove it.
Currently the behavior of shader.h depends on some constants that
are defined differently in vertex and fragment programs.
This patch cleans that up by splitting the relevant symbols in
vertex program and fragment program variants
nvfx: draw: make perspective corrective texturing work
We must divide everything in the position by w, and emit position as
a 4-component vector.
Not sure why we must divide, but it works (see progs/redbook/checker).
nvfx: fix viewport state after bypass removal for swtnl
The adjustment of nv30/nv40 after the removal of bypass incorrectly
removed the hardware viewport bypass code, which we still need for
swtnl and also forgot to remove NVFX_NEW_RAST from pipe.
nv30, nv40: move last files to nvfx/ and rm -rf nv30 nv40
This is the last nvfx unification patch.
nv[34]0_fragtex.c are moved to the common directory
nv[34]0_shader.h are renamed to nv[34]0_vertprog.h and moved to
the common directory
The separate nv30 and nv40 directories are removed from the build
system
