Some bits were already there for texture views but some were missing.
In particular for cube map views things needed to change a bit.
For simplicity I ended up removing the separate face addr bit (just use
the z bit) - cube arrays didn't use it already, so just follow the same
logic there. (In theory using separate bits could allow for better hash
function but I don't think anyone ever did some measurements of that so
probably not worth the trouble, if we'd reintroduce it we'd certainly
wanted to use the same logic for cube arrays and cube maps.)
Also extend the seamless cube sampling to cube arrays - as there were no
piglit failures before this is apparently untested, but things now generally
work quite the same for cube textures and cube array textures so there
hopefully shouldn't be any trouble...

NOTE: The implementation was initially one patch, this. All the history is kept
here, even though all the core mesa changes were moved to the parent of this
patch.
This patch implements ARB_pipeline_statistics_query. This addition to GL does
not add a new API. Instead, it adds new tokens to the existing query APIs. The
work to hook up the new tokens is trivial due to it's similarity to the previous
work done for the query APIs. I've implemented all the new tokens to some
degree, but have stubbed out the untested ones at the entry point for Begin().
Doing this should allow the remainder of the code to be left in.
The new tokens give GL clients a way to obtain stats about the GL pipeline.
Generally, you get the number of things going in, invocations, and number of
things coming out, primitives, of the various stages. There are two immediate
uses for this, performance information, and debugging various types of
misrendering. I doubt one can use these for debugging very complex applications,
but for piglit tests, it should be quite useful.
Tessellation shaders, and compute shaders are not addressed in this patch
because there is no upstream implementation. I've implemented how I believe
tessellation shader stats will work for Intel hardware (though there is a bit of
ambiguity). Compute shaders are a bit more interesting though, and I don't yet
know what we'll do there.

It turns out we can allow COHERENT storage/mappings all the time,

of CPU mappings. If we were to use CPU maps on non-LLC (which might be

slowness), those would be PERSISTENT but not COHERENT, but doing that

This extension provides a way for an application to render to multiple
surfaces with different buffer formats without having to use multiple
contexts. An EGLContext can be created without an EGLConfig by passing
EGL_NO_CONFIG_MESA. In that case there are no restrictions on the surfaces
that can be used with the context apart from that they must be using the same
EGLDisplay.
_mesa_initialze_context can now take a NULL gl_config which will mark the
context as ‘configless’. It will memset the visual to zero in that case.
Previously the i965 and i915 drivers were explicitly creating a zeroed visual
whenever 0 is passed for the EGLConfig. Mesa needs to be aware that the
context is configless because it affects the initial value to use for
glDrawBuffer. The first time the context is bound it will set the initial
value for configless contexts depending on whether the framebuffer used is
double-buffered.

On earlier hardware, we had to implement math in the shader to translate
Y-tiled or untiled coordinates to W-tiled coordinates (which is what
BLORP does today in order to texture from stencil buffers).
On Broadwell, we can simply state that it's W-tiled in SURFACE_STATE,
and adjust the pitch. This is much easier.
In the surface state code, I chose to handle the "should we sample depth
or stencil?" question separately from the setup for sampling from
stencil. This should make it work with the BindRenderbufferTexImage
hook as well, and hopefully be reusable for GL_ARB_texture_stencil8
someday.

While the GL_ARB_stencil_texturing extension does not allow the creation
of stencil textures, it does allow shaders to sample stencil values
stored in packed depth/stencil textures.
Specifically, applications can call glTexParameter* with a pname of
GL_DEPTH_STENCIL_TEXTURE_MODE and value of either GL_DEPTH_COMPONENT or
GL_STENCIL_INDEX to select which component they wish to sample. The
default value is GL_DEPTH_COMPONENT (for traditional depth sampling).
Shaders should use an unsigned integer sampler (presumably usampler2D)
to access stencil data. Otherwise, results are undefined. Using shadow
samplers with GL_STENCIL_INDEX selected also is undefined behavior.
This patch creates a new gl_texture_object field, StencilSampling, to
indicate that stencil should be sampled rather than depth. (I chose to
use a boolean since I figured it would be more convenient for drivers.)
It also introduces the [Get]TexParameter code to get and set the value,
and of course the extension plumbing.

Almost every driver already supported it. All current and future
Gallium drivers always support it, and most existing classic drivers
support it.
This only changes radeon and nouveau.
This extension only adds data types that can be passed to, for example,
glTexImage2D. It does not add internal formats. Since you can already
pass GL_FLOAT to glTexImage2D this shouldn't pose any additional issues
with those drivers. Note that r200 and i915 already supported this
extension, and they don't support floating-point textures either.

Mesa now has a real, feature-rich EGL implementation on X11 via xcb.
Therefore I believe there is no longer a practical need for the egl_glx
driver.
Furthermore, egl_glx appears to be unmaintained. The most recent
nontrivial commit to egl_glx was 6baa5f1 on 2011-11-25.
Tested by running weston-smoke in windowed Weston on X with i965.

The dd_function_table::BlitFramebuffer is already initialized to
_mesa_meta_BlitFramebuffer, so it should just work.
Tested on a Radeon 7500 (OpenGL renderer string: Mesa DRI R100 (RV200
5157) TCL DRI2). I couldn't do a full piglit run because it would tank
the system with or without this patch. I just ran all the blit tests
(-t blit to piglit-run.py). Only fbo-sys-sub-blit failed. All of the
other tests that weren't skipped (i.e., all the multisample and sRGB
tests skip) passed.

This extension enabled the use of texture array with fixed-function and
assembly fragment shaders. No applications are known to use this
extension.
NOTE: This patch regresses GL_TEXTURE_1D_ARRAY and GL_TEXTURE_2D_ARRAY
cases of the copyteximage piglit test. The test is incorrectly using
texture arrays with fixed function while only requiring the
GL_EXT_texture_array extension. A fix for the test has been posted to
the piglit mailing list.

This adds an extension called EGL_WL_create_wayland_buffer_from_image
which adds the following single function:
struct wl_buffer *
eglCreateWaylandBufferFromImageWL(EGLDisplay dpy, EGLImageKHR image);
The function creates a wl_buffer which shares its contents with the given
EGLImage. The expected use case for this is in a nested Wayland compositor
which is using subsurfaces to present buffers from its clients. Using this
extension it can attach the client buffers directly to the subsurface without
having to blit the contents into an intermediate buffer. The compositing can
then be done in the parent compositor.
The extension is only implemented in the Wayland EGL platform because of
course it wouldn't make sense anywhere else.
.. and mark them off on the extensions list as done.
V2: Enable only if pipelined register writes work.
V3: Also update relnotes

Supporting this extension turns out to simplify our code a bit over not
supporting this extension, once the glBufferSubData() synchronization code
lands.
v2: Use 16 byte alignment like we do for uniform buffers, due to unaligned
access penalties.
