The only difference between nv30 and nv40 is that nv30 allowed swizzling
for more texture types.
This patch preserves the existing behavior, using conditional code.
Note however that this does not make sense, since all texture types can
be swizzled on nv40 and probably on nv30 too.
However, the handling of swizzled surfaces in the current 2D code is
partially broken, so it's best not to touch this.
A whole rewrite of the 2D code will be submitted, which will solve this
problem.
|
|
The files are identical, except for the fact that the nv40 version
forgets to unreference the stateobj.
Unified to the correct nv30 version.
|
|
|
|
|
|
|
|
|
|
The files are the same except for swtnl support on nv40 and for
texture cache flushing on nv40.
Unify them, and use a macro to define 4 versions of render_states,
for all combinations of nvfx and hwtnl/swtnl.
|
|
|
|
|
|
Will be used to hold source files unified between nv30 and nv40.
Eventually all nv30 and nv40 code will be moved there and the
nv30 and nv40 directories will be removed.
|
|
This will make it faster to check for nv40.

This patch unifies nv[34]0_screen.h, nv[34]0_context.h and
nv[34]0_state.h
The unified files are put in a new "nvfx" directory.
nv30_context.h and nv40_context.h still exist to hold the function
prototypes and include nvfx_context.h
nv[34]0_screen.h and nv[34]0_state.h are deleted, replaced by the
unified versions.
nv40 includes some extra fields for swtnl and user clip planes
support.
These fields will be unused on nv30 until that functionality gets
added to it too (by unification with nv40).
|
|
Result of running:
perl -i -p -e 's/rankine/eng3d/g; s/curie/eng3d/g;' nv[34]0/*.[ch]
This will allow to more easily unify nv30 and nv40.
|
|
This makes nv30_state.h equivalent to nv40_state.h
|
|
It was decided to just use the NV34TCL_ constants for constants
common between nv30 and nv40, and deprecate the NV40TCL_ versions.
This patch changes the nv40 driver to use NV34TCL_ constants for
common functionality.
This reduces differences between nv30 and nv40 to ease further
unification.

This can break on systems that don't have a system X installation.

Oh look, an undocumented feature. It's a nice tool for benchmarking
texturing.
|
|
Two bug fixes at the same time. :)
|
|
E.g. when mapping buffers could flush CS or cause waiting
for a busy buffer.
The side effect of this is it also fixes progs/demos/arbocclude however
a separate fix should be proposed to address this issue in other cases
it might occur.
|
|
|
|
|
|
Now that transfers are context objects their sideeffects must happen in
order when used by the state tracker, but that synchronization must be
bypassed when used inside the driver, or it would cause infinite
recursion.
|
|
Replicates softpipe.
|
|
Otherwise IDEs and debuggers have trouble distinguishing from softpipe's
setup_context.

contexts
It requires changes not ony to the state tracker but to the python
scripts too.
|
|
It is very likely that the same surface will be flushed again and again.
Caching the surface should reduce the overhead of surface creation.
|
|
Not perfect, but the kernel should shut up now.

|
|
Quite a bit a hair pulling was involved...

Allows compiz to work in depth 16.
The DRI2 getBuffersWithFormat hook is only required for 16/32 bit depth
buffers, for colour buffers the only requirement is that the format matches
the drawable depth, which we can't check here.

The mapping for vertex_array_bgra:
(gl -> st -> translate)
GL_RGBA -> PIPE_FORMAT_R8G8B8A8 (RGBA) -> no swizzle (XYZW)
GL_BGRA -> PIPE_FORMAT_A8R8G8B8 (ARGB) -> ZYXW (BGRA again??)
Iẗ́'s pretty clear that PIPE_FORMAT_A8R8G8B8 here is wrong. This commit
fixes the pipe format and removes obvious workarounds in util/translate.
Tested with: softpipe, llvmpipe, r300g.

Make the kernel even less likely to barf on us.
