This can happen when checking if a software fallback for a higher level
operation (such as GenerateMipmap) is needed.

We could potentially do this on G45 as well, though the units are
different. On 965, the timestamp is tied to hclk, which would make
supporting it harder.

This is a workaround for Ironlake errata. The emit_mi_flush is used
for a few purposes:
1) Flushing write caches for RTT (including blit to texture)
2) Pipe fencing for sync objects
3) Spamming cache flushes to track down cache flush bugs
Spamming cache flushes seems less important than following the docs,
and we should probably do that with a different mechanism than the one
for render cache flushes.

The es1 and es2 dispath table initialization code is generated from the
API XML files and we can't easily share the dispatch table code setup.
Keep the _mesa_init_shader_dispatch() part of the patch, but roll back
the static-ization of shader entrypoints so es1 and es2 dispatch
initialization still works.

Refactor the code for all the glGetVertexAttrib() functions.

Still need to plug in API dispatch...

Needed for vertex shaders too.

Convert Z from a normalized value in the range [0, 1] to an
object-space Z coordinate in [-1, +1] so that drawing at the new Z
position with the default/identity ortho projection results in the
original Z value. Used by the meta-Clear, Draw/CopyPixels and Bitmap
functions where the Z value comes from the clear value or raster
position.
Fixes piglit tests fdo23670-depth_test, quad-invariance and
glsl-orangebook-ch06-bump as well as oglc zbfunc.c.

The check was disabled when FEATURE_OES_framebuffer_object was enabled,
since that used to mean we weren't implementing regular OpenGL semantics.
Now that we can compile in support for multiple APIs, change the #ifdef to
compile the check in when FEATURE_GL is enabled and enable the check for
contexts that implement OpenGL at runtime.
|
|
|
|
Now that we can support different APIs at runtime, we need to check the
context for the API we're currently providing as well.

We should be able to do 16, but are limited by Mesa's static buffer
allocations.
|
|
If you used all 4 color targets we currently support, we would see 0
and end up just writing the first output. Give enough bits that we
can do the maximum of 16.
Fixes piglit fbo-drawbuffers-maxtargets.

The idea would be that you could have multiple send messages going on
if nothing depended on the previous message's results and you used a
different send message. The problem is that the later send requires
the VUE handle returned by the first send's allocate anyway.

Before we would throttle in the flush callback prior to round-tripping
to the server to do copyregion or swapbuffer. Now, instead just note
that we need to throttle and do it in intel_prepare_render(), which
will be called after receiving the response from the server but before
we start rendering the next frame. Even if the server also throttles
us in swapbuffer, this just makes the throttling a no-op when we hit
intel_prepare_render(). With that we can drop the
using_dri2_swapbuffers hack and just always throttle.

adapt to blit changes, and also handle a bit more msaa state in theory
(incomplete, doesn't handle resolves in any way for now).

|
The linux-debug target builds...

This is similar to the GL_QUAD_STRIP -> TRIANGLE_STRIP optimization --
the GS usage to split the quads into tris is a huge bottleneck, so a
quick check improves glean blendFunc time massively (width * height of
the window of single-pixel GL_QUADS, many many times). This may also
end up helping with cairo performance, which sometimes ends up drawing
a single quad.
|
|
While sometimes rendering occurs in the form of blits for TexImage, it
doesn't interact with the window system renderbuffers, so skip it.

This removes references to symbols in draw module for OpenGL ES build.
As OpenGL ES does not support feedback/selection mode, draw module is
used in pathes that will never be reached. However, if the symbols are
referenced, it will bloat the final shared libraries unnecessarily.
This is serious when LLVM is enabled.

With the omit list gone, there are not too many differences in building
core mesa and ES overlay. Remove the mesa/es and build both of them in
src/mesa/Makefile.
|
|
vbo/vbo_save* are the last members on the omit list. Test FEATURE_dlist
in the sources and remove the omit list.
|
|
This allows atifragshader.h to be used without knowing if
FEATURE_ATI_fragment_shader is enabled. As a result, atifragshader.c is
removed from the omit list in ES overlay.
|
|
All ES overlay sources have been merged into core Mesa. Not much is
left in sources.mak so merge it into Makefile.
