Yes I am fixing r300c ... who knew?

This will help in bufmgr debugging and aub dumping.

This lets Mesa work like other OpenGL implementations with regard
to indexing uniform arrays. See comments for details.
Note: this is a candidate for the 7.8 branch.

Both softpipe and llvmpipe pass the piglit half float test.

We want to check the incoming renderbuffer format, not the (potentially
non-existant) current attachment.
Fixes segfault w/ fbotexture -ds2.
NOTE: this will be applied to the 7.8 branch too.

Use _mesa_meta_GenerateMipmap. It is Fast Enough(tm).

When generating or uploading a new (higher) mipmap level for an image,
we can need to allocate a miptree for a level greater than
texObj->MaxLevel.

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.
