Start adding some new pipe_transfer code.
Texturing is totally broken at this point but non-texture programs
seem to run OK.
|
|
Update framebuffer color/z/stencil mapping/unmapping.
|

|
The debug functions depend on several util function for os abstractions, and
these depend on debug functions, so a seperate module is not possible.
|
|
Suggested by Jonathan Adamczewski. There may be more places to do this...

The Cell texture code really needs a thorough inspection and clean-up someday...

move it to pipe/internal/p_winsys_screen.h and start converting
the state trackers to the screen usage
|
|
allows the driver to overwrite buffer allocation, first step on the way
to making winsys interface internal to the drivers. state trackers and
the code above it will go through the screen
|
|
|
|
|
|
|
|
Without the f, the constant is treated as a double, resulting in
slower arithmetic and libgcc conversion calls each time CEILF()
is used.
|
|
|
|
Replace cell_batch{align,alloc)*() with cell_batch_alloc16(), allocating
multiples of 16 bytes that are 16 byte aligned.
Opcodes are stored in preferred slot of SPU machine word.
Various structures are explicitly padded to 16 byte multiples.
Added STATIC_ASSERT().
|
|
|
|
|
|
The new instruction order is 10 cycles faster.

Some of these fixes are quick band-aids for now.
|
|
Place in new xlib state-tracker. This is a statetracker for the GLX API.
|
|
|
|
Fixes moire-like artifacts seen in fslight demo.
|
|
Put setup.v{min,mid,max,provoke} into a union with qword vertex_headers.
Rewrite vertex sorting to more efficiently handle the packed data items.
Reduces spu_tri.o by ~128 bytes.
|
|
Put edge.{dx,dy} into a union with a vector and perform subtractions in
setup_sort_vertices() on vectors.
Reduces spu_tri.o by ~300 bytes.
|
|
Replace int setup.span{left,right}[2] with vec_uint4 setup.span.quad
SIMDize calculate_mask() and inline into into flush_spans()
Set setup.span.quad members using spu_shuffle() or spu_sel().
Reduces spu_tri.o by ~116 bytes.
|
|
Facilitates creation of shuffle patterns for use with spu_shuffle()
and si_shufb() intrinsics.
To be used by subsequent patches.
|
|
Basic for/while loops work now.
Only one level of loop nesting is supported at this time (same for if/else).
The progs/glsl/mandelbrot demo works, but the colors are too dim.
|
|
We don't really support this texwrap mode yet, but this enables GL 2.1
|
|
Start on ARL and address-relative indexing too.

This is a set of changes that optimizes the memory use of fragment
operation programs (by using and transmitting only as much memory as is
needed for the fragment ops programs, instead of maximal sizes), as well
as eliminate the dependency on hard-coded maximal program sizes. State
that is not dependent on fragment facing (i.e. that isn't using
two-sided stenciling) will only save and transmit a single
fragment operation program, instead of two identical programs.
- Added the ability to emit a LNOP (No Operation (Load)) instruction.
This is used to pad the generated fragment operations programs to
a multiple of 8 bytes, which is necessary for proper operation of
the dual instruction pipeline, and also required for proper SPU-side
decoding.
- Added the ability to allocate and manage a variant-length
struct cell_command_fragment_ops. This structure now puts the
generated function field at the end, where it can be as large
as necessary.
- On the PPU side, we now combine the generated front-facing and
back-facing code into a single variant-length buffer (and only use one
if the two sets of code are identical) for transmission to the SPU.
- On the SPU side, we pull the correct sizes out of the buffer,
allocate a new code buffer if the one we have isn't large enough,
and save the code to that buffer. The buffer is deallocated when
the SPU exits.
- Commented out the emit_fetch() static function, which was not being used.

As suggested by Brian Paul: in the case of a twiddling error, instead
of reporting the bad format number (which is all but unusable), report
the more useful enum name.
