Without this, the build fails for me when trying to build from a generated tar
file after running just ./configure. (It's not clear to me why I didn't
encounter similar breakage with previous releases.)
This reverts commit fb3e55f898.
This commit was identified as causing the piglit
glx-create-context-current-no-framebuffer test to crash, (where, previously,
it merely failed without crashing).
Instead of checking width==height in four places, just do it in
_mesa_legal_texture_dimensions() where we do the other width, height,
depth checks. Similarly, move the check that cube map array depth is
a multiple of 6.
This change also fixes some missing cube dimension checks for the
glTexStorage[23]D() functions.
Remove width==height assertion in _mesa_get_tex_max_num_levels() since
that's called before the other size checks for glTexStorage.

For a few reasons.
1: In the (current) common case, these conditionals are never true. All
we're doing by checking them is slowing down MakeCurrent. The server
does these checks already anyway.
2: GLX >= 3.0 contexts may legally be made current without a bound

For some reason that I don't yet fully understand, Glaze does not work with

Beyond that specific reason, all of the reasons for which libGL.so is linked
with -Bsymbolic, (see the commit history), should also apply here.
[*] The specific behavior I am seeing is that when Glaze calls dlopen for
libEGL.so, ifunc resolvers within Glaze for EGL functions are called before
the dlopen returns. These resolvers cannot succeed, as they need the return
value from dlopen in order to find the functions to resolve to. I don't know
what's causing these resolvers to be called, but I have verified that linking

Hardware requires the magnitude of the largest component to not exceed

Unfortunately, we would previously multiply the array index for cube

outside the cube surface entirely, resulting in garbage rendering or in
the worst case, hangs.

The old code in dri2_glx suffered from a typographical error that caused
the default version to be 2.1 instead of 1.2 (minimum required by the
Linux OpenGL ABI). drisw_glx had a similar error resulting in a default
version of 0.1.
Some driver/card combinations (r200/RV280, i915/915G) don't support
OpenGL 2.1. These create in some corner cases an indirect context
instead of a direct context when calling glXCreateContextAttribsARB().
This happens because of a bad default value. To avoid this, just used
the default value specified by the GLX_ARB_create_context specification:
"The default values for GLX_CONTEXT_MAJOR_VERSION_ARB and
GLX_CONTEXT_MINOR_VERSION_ARB are 1 and 0 respectively. In this
case, implementations will typically return the most recent version
of OpenGL they support which is backwards compatible with OpenGL 1.0
(e.g. 3.0, 3.1 + GL_ARB_compatibility, or 3.2 compatibility
profile)"

(cherry picked from commit 8b302e1635)
Changes to the grammar for GL_ARB_shading_language_420pack (commit
6eec502) moved precision qualifiers out of the type_specifier production
chain. This caused declarations such as:
struct S {
lowp float f;
};
to generate parse errors. Section 4.1.8 (Structures) of both the GLSL
ES 1.00 spec and GLSL 1.30 specs says:
"Member declarators may contain precision qualifiers, but may not
contain any other qualifiers."
So, it sure seems like we shouldn't generate a parse error. :)
Instead of type_specifier, use fully_specified_type in struct members.
However, fully_specified_type allows a lot of other qualifiers that are
not allowed on structure members, so expeclitly disallow them.
Note, this makes struct_declaration look an awful lot like
member_declaration (used for interface blocks). We may want to
(somehow) unify these rules to reduce code duplication at some point.

Currently, Mesa allows "default" precision qualifiers to be set for

Fixes inconsistent failure of gles2conform/GL2Tests/glUniform/glUniform.test
under gnome-shell. What follows is a description of the bug and its fix.
When intel_update_renderbuffers() allocates a miptree for a winsys
renderbuffer, it propagates the renderbuffer's format to become also the
miptree's format.
If the winsys color buffer format is SARGB, then, in the first call to
eglMakeCurrent, intel_gles3_srgb_workaround() changes the renderbuffer's
format to ARGB. That is, it changes the format from sRGB to non-sRGB.
However, it changes the renderbuffer's format *after*
intel_update_renderbuffers() has allocated the renderbuffer's miptree.
Therefore, when eglMakeCurrent returns, the miptree format (SARGB)
differs from the renderbuffer format (ARGB).
If the X server reallocates the color buffer,
intel_update_renderbuffers() will create a new miptree for the
renderbuffer. The new miptree's format (ARGB) will differ from old
miptree's format (SARGB). This mismatch between old and new miptrees
causes bugs.
Fix the bug by moving intel_gles3_srgb_workaround() to occur *before*
intel_update_renderbuffers().

CC: "9.2 and 9.1" <mesa-stable@lists.freedesktop.org>
and this has already appeared in the wild.
So we extend the regular expression to pick this up as well.
(cherry picked from commit c6f3036179)
We recently adopted a new convention that patches can be nominated for the
stable branch by including a line in the commit message as follows:
CC: mesa-stable@lists.freedesktop.org
This is a convenient syntax as "git send-email" will notice this line and
automatically copy the resulting patch email to the mesa-stable mailing list.
Here we extend the regular expression in the get-pick-list.sh script to also
notice this pattern, (as well as the traditional "NOTE: This patch is a
candidate..." form.

The first field of a record in a UBO has the aligment of the record
itself.
Fixes piglit vs-struct-pad, fs-struct-pad, and (with the patch posted to
the piglit list that extends the test) layout-std140.
NOTE: The bit of strangeness with the version of visit_field without the
record_type poitner is because that method is pure virtual in the base
class. The original implementation of the class did this to ensure
derived classes remembered to implement that flavor. Now they can
implement either flavor but not both. I don't know a C++ way to enforce
that.

The outer-most record is passed into the visit_field method for

struct S1 {
vec4 v;
float f;
};
struct S {
S1 s1;
S1 s2;

uniform Ubo {

s.s1.v would get record_type = S (because s1.v is the first non-record
field in S), and s.s2.v would get record_type = S1. s.s1.f and s.s2.f
would get record_type = NULL becuase they aren't the first field of

(cherry picked from commit 5ac884fd9f)
This patch fixes a case of framebuffer blitting with renderbuffer
as color attachment and GL_LINEAR filter. Meta implementation of
glBlitFrambuffer() converts source color buffer to a texture and
uses it to do the scaled blitting in to destination buffer. Using
the exact source rectangle to create the texture does incorrect
linear filtering along the edges. This patch makes the changes to
extend the texture edges by one pixel in x, y directions. This
ensures correct linear filtering.
It fixes failing piglit fbo-attachments-blit-scaled-linear test.

We would also emit the same warning for things like

However, this second case is most likely the application trying to set

It really seems like this should be an error. I'll bet that 100% of the

doesn't explicitly forbid it.

Since disabling denorms in draw_vbo() we require the util_cpu_caps to be

(Because util_cpu_caps wasn't initialized when first calling util_fpstate_get()

GLSL ES does not allow unsized arrays, and GLSL ES 1.00 does not allow

and the initializer can explicitly size the array. The specification
even includes some examples of this:
float x[] = float[2] (1.0, 2.0); // declares an array of size 2
float y[] = float[] (1.0, 2.0, 3.0); // declares an array of size 3
float a[5];
float b[] = a;
Move the unsized array check to after the initializer has been

array initializers are not allowed.

I had removed it in commit 1e7776ca2b

version that emits events, if we're not watching for the server's events,
anyway? And why would you only invalidate on a server that emits
invalidate events, when the comment said to emit invalidates if the server
*doesn't*? Only, I missed that we otherwise don't flag that our buffers
might have changed at swap time at all, so the driver was only checking
for new buffers when triggered by the Viewport hack. Of course you don't
expect Viewport to be called after a swap.
So, this is effectively a revert of the previous commit, except that I
dropped the check for only emitting invalidates on a new server -- we
*always* need to invalidate if we're doing a SwapBuffers.

Looks like a thinko, "Hey, constant buffers can be at most 64 KiB
in size, offset can't be larger." But it can, of course.
I think piglit lacks a test for UBO and BindBufferRange that
tests if it actually works.
Almost all of the functions between the ARB and the EXT share the same
GLX protocol because the functionality is, essentially, identical.
However, there are some differences between the extensions:
- In the ARB extension, names must come from glGenBuffers.
- In the ARB extension, framebuffer objects are not shared (but they are
in the EXT).
For these reasons, glBindFramebuffer and glBindRenderbuffer have
different GLX protocol opcodes than their EXT counterparts. Currently
these functions alias each other in the dispatch table. This makes it
impossible to be truly spec conformant.
This patch enables fixing the conformance issue by splitting
glBindFramebuffer / glBindFramebufferEXT and glBindRenderbuffer /
glBindRenderbufferEXT into separate dispatch table entries.
Patches will be available shortly to:
- Fix the conformance issue.
- Stop advertising the EXT in OpenGL 3.1 (or core profiles).
HOWEVER, this does represent a compatibility break between the loader
(libGL or the Xserver GLX module) and the driver. Mesa drivers compiled
without this change will request a single dispatch table entry for
glBindFramebuffer and glBindFramebufferEXT. Since the updated loader
has different entries for each, the request will fail, and the driver
will die in a fire.
Drivers built with the change should continue to load fine on loaders
without the change. In this case, the driver will separately ask for
entries for glBindFramebuffer and glBindFramebufferEXT, and the loader
will tell it the same location. Since the loader in the server's GLX
module is not (yet) updated, this should not be a problem. We also do
not advertise the ARB extension from the server, so, again, this should
not be a problem for the server.
HOWEVER, this means that DRI1 drivers (remember mga_dri.so?) will no
longer load with libGL build hereafter. That means this patch will need
to be back ported to the 8.0 branch.

However, samplers are different. Consider a declaration such as:

There is existing code to handle sampler uniform initializers. Prior to
GLSL 4.20's "binding" keyword, sampler uniforms don't have initializers
at all, so this is somewhat surprising.
The existing code is broken into two cases: one where both the variable and
initializer are arrays, and a second where the variable and initializer are
scalars.
The first case should never occur, since array-typed initializers do not
exist for sampler uniforms. Even with the binding keyword, the
initializer is a single integer which represents the texture unit to use
for the first array element.
The second is apparently used for some fixed-function code.

The idea of this code is to disallow layout(...) sections with the
deprecated "varying" or "attribute" keywords, unless a few select
extensions are enabled which allow a more relaxed check.
In order to detect a layout(...) section, the code checks for a number
of layout qualifiers. However, it failed to check for all of them,
which could lead to layout(...) not being detected when it should.
By replacing this with has_layout(), we properly check for all layout
qualifiers, and also guarantees that new qualifiers added in the future
will not be forgotten.

Reviewed-by: Matt Turner <mattst88@gmail.com>
Currently, we store precision in ast_type_specifier, rather than
ast_type_qualifier. This works because precision is the last qualifier,
and immediately adjacent to the type.
Default precision statements (such as "precision highp float") are
represented as ast_type_specifier objects, with a boolean to indicate
that it's a default precision statement rather than an ordinary type.
ast_type_specifier::precision will be moving to ast_type_qualifier soon,
in order to support arbitrary qualifier ordering. However, we still
need to store a "this is a precision statement" flag /and/ the default
precision in ast_type_specifier.
This patch changes the boolean into a new field, default_precision.
If default_precision != ast_precision_none, it's a precision statement
with the specified precision. Otherwise, it's an ordinary type.

Most of ast_type_qualifier is simply a bitfield (represented as a
structure of unsigned:1 bits in a union with an unsigned). However, it
also contains ARB_explicit_attrib_location's location/index fields.
In the past, this has worked by simply returning the layout qualifier's
ast_type_qualifier and merging the other bits into it. However, that's
not obvious until you break it by switching $1 and $2.
Using merge_qualifier() copies them appropriately, and also properly
overrides layout qualifiers. It also checks for duplicate qualifiers,
which renders some of the checks in the previous patch unnecessary.
However, those checks provide better error messages, such as "Duplicate
interpolation qualifier", rather than just "duplicate qualifier".

Usually with fixed point renderbuffers clamping is done as part of conversion.
However, since we blend in float format, we essentially skip all conversion
steps pre-blend but since this is still a fixed point renderbuffer we must
still clamp the inputs in this case. Makes no difference for piglit though.
Obviously we could skip this if fragment color clamping is enabled, but a)
this is deprecated in OpenGL (d3d never had it) and b) we don't support it
natively so it gets baked into the shader.
Also add some comment about logic ops being broken for srgb, luckily no test

We were fixing up the blend factor to ZERO, however this only works correctly
with fixed point render buffers where the input values are clamped to 0/1
(because src_alpha_saturate is min(As, 1-Ad) so can be negative with unclamped
inputs). Haven't seen any failure anywhere due to that with fixed point SNORM
buffers (which clamp inputs to -1/1) but it should apply there as well (snorm
blending is rare, even opengl 4.3 doesn't require snorm rendertargets at all,
d3d10 requires them but they are not blendable).
Doesn't look like piglit hits this though (some internal testing hits the
float case at least). (With legacy OpenGL we could theoretically still use the
fixup to zero if the fragment color clamp is enabled, but we can't detect that
easily since we don't support native clamping hence it gets baked into the

generate_120_fs_variables was called for GLSL versions 1.20 and above,
but generate_130_fs_variables was called only for GLSL version 1.30).
In addition, it led to a lot of code duplication, since many varyings
had to be duplicated in both the FS and VS code paths. With the
advent of geometry shaders (and later, tessellation control and
tessellation evaluation shaders), this code duplication was going to
get a lot worse.
So this patch reworks things so that instead of having a separate
function for each shader type and GLSL version, we have a function for
constants, one for uniforms, one for varyings, and one for the special
variables that are specific to each shader type.
In addition, we use a class, builtin_variable_generator, to keep track
of the instruction exec_list, the GLSL parse state, commonly-used
types, and a few other variables, so that we don't have to pass them
around as function arguments. This makes the code a lot more compact.
Where it was feasible to do so without introducing compilation errors,
I've also gone ahead and introduced the variables needed for
{ARB,EXT}_geometry_shader4 style geometry shaders. This patch takes
care of everything except the GS variable gl_VerticesIn, the FS
variable gl_PrimitiveID, and GLSL 1.50 style geometry shader inputs
(using the gl_in interface block). Those remaining features will be
added later.
I've also made a slight nomenclature change: previously we used the
word "deprecated" to refer to variables which are marked in GLSL 1.40
as requiring the ARB_compatibility extension, and are marked in GLSL
1.50 onward as requiring the compatibilty profile. This was
misleading, since not all deprecated variables require the
compatibility profile (for example gl_FragData and gl_FragColor, which
have been deprecated since GLSL 1.30, but do not require the
compatibility profile until GLSL 4.20). We now consistently use the
word "compatibility" to refer to these variables.
This patch doesn't introduce any functional changes (since geometry
shaders haven't been enabled yet).

Some lame compilers can't do exp2f() and as far as I can tell they can't do
exp2() (with doubles) neither so instead of providing some workaround for
that (wouldn't actually be too bad just replace with pow) and since it is
used with a constant only just use the precalculated constant.
When only the offset to the index buffer is changed, we can skip the

srgb-to-linear is using 3rd degree polynomial for now which should be _just_
good enough. Reverse is using some rational polynomials and is quite accurate,
though not hooked into llvmpipe's blend code yet and hence unused (untested).
Using a table might also be an option (for srgb-to-linear especially).
This does not enable any new features yet because EXT_texture_srgb was already
supported via util_format fallbacks, but performance was lacking probably due
to the external function call (the table used by the util_format_srgb code may
not be all that much slower on its own).
Some performance figures (taken from modified gloss, replaced both base and
sphere texture to use GL_SRGB instead of GL_RGB, measured on 1Ghz Sandy Bridge,
the numbers aren't terribly accurate):
normal gloss, aos, 8-wide: 47 fps
normal gloss, aos, 4-wide: 48 fps
normal gloss, forced to soa, 8-wide: 48 fps
normal gloss, forced to soa, 4-wide: 47 fps
patched gloss, old code, soa, 8-wide: 21 fps
patched gloss, old code, soa, 4-wide: 24 fps
patched gloss, new code, soa, 8-wide: 41 fps
patched gloss, new code, soa, 4-wide: 38 fps
So there's a performance hit but it seems acceptable, certainly better
than using the fallback.
Note the new code only works for 4x8bit srgb formats, others (L8/L8A8) will
continue to use the old util_format fallback, because I can't be bothered
to write code for formats noone uses anyway (as decoding is done as part of
lp_build_unpack_rgba_soa which can only handle block type width of 32).
Compressed srgb formats should get their own path though eventually (it is
going to be expensive in any case, first decompress, then convert).
No piglit regressions.
v2: use lp_build_polynomial instead of ad-hoc polynomial construction, also
since keeping both linear to srgb functions for now make sure both are
compiled (since they share quite some code just integrate into the same
function).
v3: formatting fixes and bugfix in the complicated (disabled) linear-to-srgb

The D3D10 spec is very explicit about treatment of denorm floats and

Some code was already there to handle this so fix it up and enable it.

right mix of new and old components to hit this path. Deleting it
removes an untested code path and cleans up the driver a bit.

This wasn't called from anywhere; presumably it was used to examine

in a different notation than brw_disasm.c which everyone is used
to...which means I doubt anyone will want to use it.

Commit cf31a19300 removed support for BOs
backed by system memory, as it was only useful for i915. However, it
removed a little too much code: intel_bufferobj_buffer() used to call
intel_bufferobj_alloc_buffer(), and after that commit, it didn't.
This led to NULL pointer dereferences in several test cases, such as
es3conform's transform_feedback_state_variables test.
This commit restores the allocation, preserving the original behavior.
It may not be the cleanest approach, but tidying should come later.

This ensures that inter-shader outputs and inputs are properly eliminated
across 3 or more shader stages. The behavior is unchanged with 2 or less
shader stages.
For example, elimination of unused FS inputs causes elimination of matching
GS outputs, which causes elimination of the GS inputs that were needed for
evaluation of the eliminated GS outputs, which causes elimination of
matching VS outputs. An unused FS input is all that's needed to trigger
this chain reaction.

This is only used on Gen4-6; gen7_surface_state.c has Gen7+ code.

Also, the "minimum resolvable depth difference" used isn't really right as it
should be calculated according to the z values of the current primitive

Previously lp_rast_begin_query commands were always inserted into each bin,
and re-issued if the scene was restarted, while lp_rast_end_query commands
were executed for each still active query at the end of tile rasterization.
Also, the ps_invocations and vis_counter were set to zero when the respective
command was encountered.
This however cannot work for multiple queries of the same type (note that
occlusion counter and occlusion predicate while different type were also
affected).
So, change the logic to always set the ps_invocations and vis_counter to zero
at the start of tile rasterization, and then use "start" and "end" per-thread
query values when encountering the begin/end query commands instead, which
should work for multiple queries of the same type. This also means queries do
not have to be reissued in a new scene, however they still need to be finished
at end of tile rasterization, so a list of queries still active at the end of
a scene needs to be maintained.
Also while here don't bin the queries which don't do anything in rasterization.
(This change does not actually handle multiple queries of the same type yet,
as the list of active queries is just a simple fixed array and setup can still
only have one query active per type.)

Over the last few years, the compiler has grown to support 7 different
language versions and 6 extensions that add new built-in types. With
more and more features being added, some of our core code has devolved
into an unmaintainable spaghetti of sorts.
A few problems with the old code:
1. Built-in types are declared...where exactly?
The types in builtin_types.h were organized in arrays by the language
version or extension they were introduced in. It's factored out to
avoid duplicates---every type only exists in one array. But that
means that sampler1D is declared in 110, sampler2D is in core types,
sampler3D is a unique global not in a list...and so on.
2. Spaghetti call-chains with weird parameters:
generate_300ES_types calls generate_130_types which calls
generate_120_types and generate_EXT_texture_array_types, which calls
generate_110_types, which calls generate_100ES_types...and more
Except that ES doesn't want 1D types, so we have a skip_1d parameter.
add_deprecated also falls into this category.
3. Missing type accessors.
Common types have convenience pointers (like glsl_type::vec4_type),
but others may not be accessible at all without a symbol table (for
example, sampler types).
4. Global variable declarations in a header file?
#include "builtin_types.h" in two C++ files would break the build.
The new code addresses these problems. All built-in types are declared
together in a single table, independent of when they were introduced.
The macro that declares a new built-in type also creates a convenience
pointer, so every type is available and it won't get out of sync.
The code to populate a symbol table with the appropriate types for a
particular language version and set of extensions is now a single
table-driven function. The table lists the type name and GL/ES versions
when it was introduced (similar to how the lexer handles reserved
words). A single loop adds types based on the language version.
Explicit extension checks then add additional types. If they were
already added based on the language version, glsl_symbol_table simply
ignores the request to add them a second time, meaning we don't need
to worry about duplicates and can simply list types where they belong.

However, relying on this is extremely fragile. There's no particular
reason the underlying type objects need to be stored in an array. They
could be individual class members, possibly with padding between them.
Then the pointer arithmetic would break, and we'd get bad pointers to
non-heap allocated data, causing subtle breakage that can't be detected
by valgrind. Cue insanity.
Or someone could simply reorder the type variables, causing us to get
the wrong type entirely. Also cue insanity.
Writing this explicitly is much safer. With the new helper functions,
it's a bit less code even.

This patch introduces new functions to quickly grab a pointer to a
vector type. For example:
glsl_type::bvec(4) returns glsl_type::bvec4_type
glsl_type::ivec(3) returns glsl_type::ivec3_type
glsl_type::uvec(2) returns glsl_type::uvec2_type
glsl_type::vec(1) returns glsl_type::float_type
This is less wordy than glsl_type::get_instance(GLSL_TYPE_BOOL, 4, 1),
which can help avoid extra word wrapping.

We want to access the user buffer, if available, when primitive restart is
enabled and the restart index/primitive type is not natively supported.
And since we are handling index buffer uploads in the driver with this change,
we can also work around misalignment of index buffer offsets.
Rename ilo_finalize_states() to ilo_finalize_3d_states(), and bind
pipe_draw_info to the context when it is called. This saves us from having to
pass pipe_draw_info around in several places.
The polygon offset math used for triangles by the WM is "OffsetUnits * 2 *
MRD + OffsetFactor * m" where 'MRD' is the minimum resolvable difference
for the depth buffer (~1/(1<<16) or ~1/(1<<24)), 'm' is the approximated
slope from the GL spec, and '2' is this magic number from the original
i965 code dump that we deviate from the GL spec by because "it makes glean
work" (except that it doesn't, because of some hilarity with 0.5 *
approximately 2.0 != 1.0. go glean!).
This clipper code for unfilled polygons, on the other hand, was doing
"OffsetUnits * garbage + OffsetFactor * m", where garbage was MRD in the
case of 16-bit depth visual (regardless the FBO's depth resolution), or
128 * MRD for 24-bit depth visual.
This change just makes the unfilled polygons behavior match the WM's
filled polygons behavior.

For conditional rendering this makes it possible to skip rendering
if either the predicate is true or false, as supported by d3d10
(in fact previously it was sort of implied skip rendering if predicate
is false for occlusion predicate, and true for so_overflow predicate).
There's no cap bit for this as presumably all drivers could do it trivially
(but this patch does not implement it for the drivers using true
hw predicates, nvxx, r600, radeonsi, no change is expected for OpenGL
functionality).

When a resource is busy and is mapped with
PIPE_TRANSFER_DISCARD_WHOLE_RESOURCE, the underlying bo is replaced. We need
to mark states affected by the resource dirty.
With this change, we no longer have to emit vertex buffers and index buffer
unconditionally.
Even with hardware contexts, since we do not pin resources, we have to re-emit
the states so that the resources are referenced (by cp->bo) and their offsets
are updated in case they are moved. This also allows us to elimiate cp flush
in is_bo_busy().
Problem: The IEEE float optimized version of UNCLAMPED_FLOAT_TO_UBYTE
in macros.h computed incorrect results for inputs in the range
0x3f7f0000 (=0.99609375) to 0x3f7f7f80 (=0.99803924560546875)
inclusive. 0x3f7f7f80 is the IEEE float value that results in 254.5
when multiplied by 255. With rounding mode "round to closest even
integer", this is the largest float in the range 0.0-1.0 that is
converted to 254 by the generic implementation of
UNCLAMPED_FLOAT_TO_UBYTE. The IEEE float optimized version
incorrectly defined the cut-off for mapping to 255 as 0x3f7f0000
(=255.0/256.0). The same bug was present in the function
float_to_ubyte in u_math.h.
Fix: The proposed fix replaces the incorrect cut-off value by
0x3f800000, which is the IEEE float representation of 1.0f. 0x3f7f7f81
(or any value in between) would also work, but 1.0f is probably
cleaner.

We have to use pipe->blit, not resource_copy_region, so that the read buffer

which just did format conversion (obsoleted by the blit).

ignored).
Last but not least, the format choosing is improved to take float and integer
read buffers into account.

There were 2 issues with it:
- resource_copy_region doesn't allow different sample counts of both src

(this was the main motivation for using pipe->blit)

rtt_face and rtt_slice were ignored.

Previously we would generate uniform locations as (slot << 16) +
array_index. We do this to handle applications that assume the location
of a[2] will be +1 from the location of a[1]. This resulted in every
uniform location being at least 0x10000. The OpenGL 4.3 spec was
amended to require this behavior, but previous versions did not require
locations of array (or structure) members be sequential.
We've now encountered two applications that assume uniform values will
be "small." As far as we can tell, these applications store the GLint
returned by glGetUniformLocation in a int16_t or possibly an int8_t.
THIS BEHAVIOR IS NOT GUARANTEED OR IMPLIED BY ANY VERSION OF OpenGL.
Other implementations happen to have both these behaviors (sequential
array elements and small values) since OpenGL 2.0, so let's just match
their behavior.

This patch adds code to place mcs_state into INTEL_MCS_STATE_RESOLVED
for miptrees that are capable of supporting fast color clears. This
will have no effect on buffers that don't undergo a fast color clear;
however, for buffers that do undergo a fast color clear, an MCS
miptree will be allocated (at the time of the first fast clear), and
will be used thereafter.
Reviewed-by: Eric Anholt <eric@anholt.net>
In certain circumstances the memory region underlying a miptree is
shared with other miptrees, or with other code outside Mesa's control.
This happens, for instance, when an extension like GL_OES_EGL_image or
GLX_EXT_texture_from_pixmap extension is used to associate a miptree
with an image existing outside of Mesa.
When this happens, we need to disable fast color clears on the miptree
in question, since there's no good synchronization mechanism to ensure
that deferred clear writes get performed by the time the buffer is
examined from the other miptree, or from outside of Mesa.
Fortunately, this should not be a performance hit for most
applications, since most applications that use these extensions use
them for importing textures into Mesa, rather than for exporting
rendered images out of Mesa. So most of the time the miptrees
involved will never experience a clear.

This patch implements the "render target resolve" blorp operation.
This will be needed when a buffer that has experienced a fast color
clear is later used for a purpose other than as a render target
(texturing, glReadPixels, or swapped to the screen). It resolves any
remaining deferred clear operation that was not taken care of during
normal rendering.
Fortunately not much work is necessary; all we need to do is scale
down the size of the rectangle primitive being emitted, run the
fragment shader with the "Render Target Resolve Enable" bit set, and
ensure that the fragment shader writes to the render target using the
"replicated color" message. We already have a fragment shader that
does that (the shader that we use for fast color clears), so for
simplicity we re-use it.

When processing a buffer received from the X server,
intel_process_dri2_buffer() examines intel_region::name to determine
whether it's received a brand new buffer, or the same buffer it
received from the X server the last time it made a request.
However, this didn't work properly, because in the call to
intel_miptree_create_for_dri2_buffer(), we create a fresh intel_region
object to represent the buffer, and this was causing us to forget the
buffer's previous name.
This patch fixes things by copying over the region name when creating
the fresh intel_region object.
At the moment, this is just a minor performance optimization.

ensure that the fast color clear state for a buffer doesn't get
