When EU executes 'wait' instruction, it stalls and sets notification
register state. Host can issue MMIO write to clear notification
register state to allow EU continue on executing again.

Fixes fd.o bug 27216. May also be the root cause of fd.o bug 28950.
We weren't propogating the storage info for the x=foo() expression up
through the IR tree to the inequality expression.
NOTE: This is a candidate for the Mesa 7.8 branch.
First, this undoes commit e503af4baa
so we use iround() in lp_build_nearest_mip_level().
Second, in lp_build_sample_general() we need to check if we're sampling
a cube map before anything else. Choose the cube face and then recompute
the partial derivatives of (S,T) with respect to the chosen cube face.
Before, we were using the directional (S,T,R) derivatives to compute
the LOD.
Third, work around an apparent bug in LLVM 2.7 where setting the lod
variable to a const(0) value results in bad x86 code. See comments in
the code.
The _slang_*_output_name() functions had one too many loop iterations
because of the sentinal end-of-list values in the vertOutput array.
Just use Elements() everywhere.
Plus fix minor error in lp_build_iceil() by tweaking the offset value.
And add a bunch of comments for the round(), trunc(), floor(), ceil()
functions.
it was wrong to put this in the fs paths, but it was easier to just
stuff it along the fragment texture sampling paths. the patch
disconnects vertex texture sampling and just maps the textures
before the draw itself and unmaps them after.
softpipe doesn't implement the draw's llvm tex sampling interface
so make sure draw can handle the cases where the driver doesn't
implement the interface
Assert ctx->Driver.NewTransformFeedback if the feature is enabled; Use
the default callbacks otherwise. The rest of core mesa expects the
state to be initialized.
Driver loading is now splitted into two stages. In the first stage, an
_EGLModule is created for each driver: user driver, default drivers, and
all files in the search directories that start with "egl_". Modules are
not loaded at this stage.
In the second stage, each module is loaded to initialize a display. The
process stops at the first module that can initialize the display.
If eglGetProcAddress is called before eglInitialize, the same code path
will be taken to find the first module that supports
EGL_DEFAULT_DISPLAY. Because we do not want to initialize the display,
drv->Probe is used instead in this case.
