Render results are only visible when the render cache is flushed.
softpipe_is_texture_referenced must reflect that or transfers to/from the
textures bound in the framebuffer won't be proceeded of the necessary
flush, causing transfer data to be outdated/clobbered.
This fixes conform drawpix test with softpipe.

Fixes segfault regression in progs/glsl/identity.c
|
|
Instead, a new pipe_transfer object has to be created and mapped for
transferring data between the CPU and a texture. This gives the driver more
flexibility for textures in address spaces that aren't CPU accessible.
This is a first pass; softpipe/xlib builds and runs glxgears, but it only shows
a black window. Looks like something's off related to the Z buffer, so the
depth test always fails.

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
|
|
reuse the size of the actual buffer

We were indexing sp_constants[i] outside the loop so i was 2.
Replace i with PIPE_SHADER_VERTEX.
Also, replace magic '2' with PIPE_SHADER_TYPES in a few places.

But when creating surfaces, adjust incoming flags from GPU->CPU usage.

The later follows the naming scheme of other limits.
Keep the old definition until all possible usage is updated.
|
|
Otherwise, we won't have our constants when we run the fragment shader.
Fixes crash in glsl tests when SP_VBUF=1.

Update the Makefiles and includes for the new paths.
Note that there hasn't been no separation of the Makefiles yet, and make is
jumping all over the place. That will be taken care shortly. But for now, make
should work. It was tested with linux and linux-dri. Linux-cell and linux-llvm
might require some minor tweaks.

This is in a separate commit to ensure renames are properly preserved.
