This is a step towards providing a direct route for drivers accepting
GLSL IR for codegen. Perhaps more importantly, it runs the fixed
function fragment program through the GLSL IR optimization. Having
seen how easy it is to make ugly fixed function texenv code that can
do unnecessary work, this may improve real applicatinos.
On converting fixed function programs to generate GLSL, the linker
became cranky that we were trying to make something that wasn't a
linked vertex+fragment program. Given that the Mesa GLES2 drivers
also support desktop GL with EXT_sso, just telling the linker to shut
up seems like the easiest solution.
As pointed out by Michel Dänzer, gcc -lstdc++ doesn't work on all systems,
because it may require other libraries which are only pulled in implicitly
by g++. And libstdc++ is available only with GNU compiler.
Use c++ compiler for linking and remove redundant LDFLAGS += -lstdc++
all over the tree.
In addition to setting up the flags correctly, this renames the
generated libraries to ensure they get 'Mangled' in the name.
This is very useful for distros and the like, where mangled Mesa
and non-mangled GL libraries typically need to be installed
side-by-side.

Scalar instruction that need to write to the xyz components of a
register must reserve the RGB instruction slot for a REPL_ALPHA
instruction. With this commit, the scheduler will attempt to free
the RGB slot by moving the write to the w component of a register.
Introuduce a simple function called copy_data to do the image data copy
stuff for all the save_CompressedTex*Image function. The function check
the NULL data case to avoid some potential segfault. This also would
make the code a bit simpler and less redundance.

For glReadPixels, the user supplied pixels have format
GL_UNSIGNED_INT_24_8. But, when the depthstencil buffer's format was
MESA_FORMAT_S8_Z24, the fastpath read from the buffer without reordering
the depth and stencil bits. To fix this, this patch just skips the
fastpath when the format is not MESA_FORMAT_Z24_S8.
The problem and fix for glWritePixels is analagous.
Fixes the Piglit tests below on i965/gen6 and causes no regressions.

This is required for an accurate implementation of d3d1x's
CheckFormatSupport query.
It also seems generally useful for state trackers, which could
choose alternative rendering paths or formats if blending would
come at a significant performance loss.
The texture semaphore allows for prefetching of texture data. On my
RV515, this increases the FPS of Lightsmark by 33% (This is with the
reg_rename pass enabled, which is enabled in the next commit).
There is a new env variable now called RADEON_TEX_GROUP, which allows
you to specify the maximum number of texture lookups to do at once.
The default is 8, but different values could produce better results
for various application / card combinations.
We no longer emit full instructions immediately after they have been
merged. Instead merged instructions are added to the ready list and
the scheduler can commit them whenever it wants.
This is supported by the pseudo-code on pages 27 and 28 (pages 41 and
42 of the PDF) of the OpenGL 2.1 spec. The last part of the
implementation of ArrayElement is:
if (generic attribute array 0 enabled) {
if (generic vertex attribute 0 array normalization flag is set, and
type is not FLOAT or DOUBLE)
VertexAttrib[size]N[type]v(0, generic vertex attribute 0 array element i);
else
VertexAttrib[size][type]v(0, generic vertex attribute 0 array element i);
} else if (vertex array enabled) {
Vertex[size][type]v(vertex array element i);
}
Page 23 (page 37 of the PDF) of the same spec says:
"Setting generic vertex attribute zero specifies a vertex; the
four vertex coordinates are taken from the values of attribute
zero. A Vertex2, Vertex3, or Vertex4 command is completely
equivalent to the corresponding VertexAttrib* command with an
index of zero."
Fixes piglit test attribute0.

Don't allow any "CPU" buffers to be allocated by the pb_fenced
buffer manager, since we can't protect against failures during
buffer validation.
Also, add an extra slab buffer manager to allocate buffers from
the kernel if there is a failure to allocate from our big buffer pool.
The reason we use a slab manager for this, is to avoid allocating
many very small buffers from the kernel.
v2: Increased VMW_MAX_BUFFER_SIZE and fixed some comments.

The X server has limited throttle support on the server side,
but doing this in the client has some benefits:
1) X server throttling is per client. Client side throttling can be done
per drawable.
2) It's easier to control the throttling based on what client is run,
for example using "driconf".
3) X server throttling requires drm swap complete events.
So implement a dri2 throttling extension intended to be used by direct
rendering clients.

This change releases the stw_framebuffer::mutex past creation of
the pbuffer stw_framebuffer. Without this change the pbuffers
lock is never released. Since on win32 mutexes are recursive, this
does not hurt as long as all actions on a context are done from
the same thread. But if, for example, context creation happens in
a different thread than usage, every access to the context will
block for ever.

In commit 018ea68d87, when I
de-compacted clip planes on Gen6+, I updated both the old and new VS
back-ends to reflect the change in how clip planes are stored, but I
failed to change the code in gen6_vs_state.c that uploads clip plane
constants when using the old VS back-end.
As a result, if the set of enabled clip planes wasn't contiguous
starting with 0, then clipping would not occur properly. This patch
corrects gen6_vs_state.c to upload clip plane constants in the new
de-compacted form.
This only affects the old VS back-end (which is used for
fixed-function and ARB vertex programs, not for GLSL vertex shaders).
Fixes Piglit test fixed-clip-enables.

Instead of the renderbuffer pointer. In the future, attaching a texture

Plus, remove some commented-out assertions.
