303fb5881c mesa: Add blend barrier entry point and driver hook.
Both MESA_shader_framebuffer_fetch_non_coherent and the non-coherent
variant of KHR_blend_equation_advanced will use this driver hook to
request coherency between framebuffer reads and writes.  This
intentionally doesn't hook up glBlendBarrierMESA to the dispatch layer
since the extension isn't exposed to applications yet, see [1]
for more details.

642aa58577 mesa: Add support for querying GL_FRAGMENT_SHADER_DISCARDS_SAMPLES_EXT.
This can currently only give true as result since the only way you can
expose EXT_shader_framebuffer_fetch right now is by flipping the
MESA_shader_framebuffer_fetch bit, but that could potentially change
in the future, see [1] for an explanation.

115a27357c mesa: Add extension enables for framebuffer fetch extensions.
This allows drivers to expose EXT_shader_framebuffer_fetch in GLES2+
contexts if desired.  Note that this adds boolean flags for two MESA
extensions, but only the EXT GLES-only extension is exposed for the
moment, see the cover letter of this series [1] for the rationale.

a227b0a4f1 nvc0: invalidate textures/samplers on GK104+
Like Fermi, textures and samplers are aliased between 3D and compute,
especially the TIC_FLUSH/TSC_FLUSH methods and we have to re-validate
these resources when switching between the two pipelines.

This fixes a GPU hang with Elemental (and most likely with other UE4 demos).

Tested on GK107 and GM107.

07fe2d565b program_resource: subroutine active uniforms should return NumSubroutineUniforms
Before this commit, GetProgramInterfaceiv for pname ACTIVE_RESOURCES
and all the <shader>_SUBROUTINE_UNIFORM programInterface were
returning the count of resources on the shader program using that
interface, instead of the num of uniform resources. This would get a
wrong value (for example) if the shader has an array of subroutine
uniforms.

Note that this means that in order to get a proper value, the shader
needs to be linked, something that is not explicitly mentioned on
ARB_program_interface_query spec, but comes from the general
definition of active uniform. If the program is not linked we
return 0.

v2: don't generate an error if the program is not linked, returning 0
    active uniforms instead, plus extra spec references (Tapani Palli)

56ba9656bb aubinator: Fix the tool to correctly decode the DWords
Several fixes have been added as part of this as listed below:

1) Fix the mask and add disassembler handling for STATE_DS, STATE_HS
as the mask returned wrong values of the fields.

2) Fix the GEN_TYPE_ADDRESS/GEN_TYPE_OFFSET decoding - the address/
offset were handled the same way as the other fields and that gives
the wrong values for the address/offset.

3) Decode nested/recurssive structures - Many packets contain nested
structures, ex: 3DSATE_SO_BUFFER, STATE_BASE_ADDRESS, etc contain MOC
structures. Previously, the aubinator printed 1 if there was a MOC
structure. Now we decode the entire structure and print out its fields.

4) Print out the DWord address along with its hex value - For a better
clarity of information, it is helpful to print both the address and
hex value of the DWord along with the DWord count. Since the DWord0
contains the instruction code and the instruction length, it is
unnecessary to print the decoded values for DWord0. This information
is already available from the DWord hex value.

5) Decode the <group> and the corresponding fields in the group- The
<group> tag can have fields of several types including structures. A
group can contain one or more number of fields and this has be correctly
decoded. Previously, aubinator did not decode the groups or the
fields/structures inside them. Now we decode the <group> in the
instructions and structures where the fields in it repeat for any number
of times specified.

v2: Fix the formatting (per Matt)
Make the start and end pos calculation to extract fields from a DWord
more appropriate by moving %32 away from mask() method

f6967ddd32 i965/surface_formats: Don't advertise 8 or 16-bit RGB formats
We have implicitly been not advertising these formats since we had them
turned off in the format capabilities table.  We are about to update that
table and this prevents a change in behavior.  The only change in behavior
created by this patch is that we no longer advertise support for
R16G16B16_FLOAT which means that it's now renderable which seems like a
bonus.  Maybe someday we'll want to change things to start supporting
16-bit RGB formats natively but, at the moment, there's no need.

fb90291dd5 anv/formats: Don't use an RGBX format if it isn't renderable
The whole point of using RGBX is so that we can render to it so if it isn't
renderable, that kind-of defeats the purpose.  Some formats (one example is
R32G32B32X32_SFLOAT) exist in the format table but aren't actually
renderable.  Eventually, we'd like to get away from RGBX entirely, but this
fixes hangs on BDW today.
