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.

allows to link with xmlconfig without dri_util, and has nothing drm-specific.

This is dri_util.c stripped from the drm-specific bits and will be used for
both classic and gallium swrast_dri.so

It seems that x86-64 with tls will fail to compile or load due to a missining
gl_dispatch_functions_start symbol. Not changing though, since this is how it
used to be and cannot test.

Honor the (x, y) and (width, height) pairs.

Consider this rendering sequence
* render to the back buffer
* swap buffers
* read from the front buffer
The front buffer is expected to have the contents of the back buffer.
|
|
Create a per-display pipe_context as needed to copy the contents between
framebuffer attachments. This allows us to support
GLX_MESA_copy_sub_buffer.
|
|
This basically adds a static xmesa_display to collect per-display static
variables in xm_api.c. Multiple display support is still missing, but
this is a step forward.
|
|
FBOs are created by st_new_framebuffer and cannot be casted to
st_framebuffer.

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.

Fallback to swrast for software renderbuffers
|
|
|
|
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.
