_mesa_meta_begin() sets up an orthographic project and initializes the

We previously adjusted this script so that the new-style markup, (with CC)
would only trigger if it specifically mentioned "9.1", but the old-style
markup (with "NOTE:") was always triggering. Fix it to look for "9.1" as well.
This removes several patches from the current output.
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)"
Refactor all the default value setting to dri2_convert_glx_attribs, and
make sure the correct defaults are set in that one place.

GLSL ES does not allow unsized arrays, and GLSL ES 1.00 does not allow
array initializers. However, GLSL ES 3.00 allows array initializers,
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
processed. If the array is still unsized, generate the error. This
should have no effect in GLSL ES 1.00 because, as previously mentioned,
array initializers are not allowed.

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
libEGL with -Bsymbolic causes this problematic behavior to stop.

*doesn't*? Only, I missed that we otherwise don't flag that our buffers

(presumably based on the assumption that such an if statement would be

case--it's possible that previous optimization stages might simplify
more complex code down to this empty if statement, in which case it
won't be eliminated until the next time through the optimization loop.
So is_loop_terminator() needs to handle it. Fortunately it's easy to
handle--it's not a loop terminator because it does nothing.

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

we call _mesa_glsl_initialize_types(), which checks state->es_shader and
language_version. If it isn't valid, it hits an assertion failure.
Fixes Piglit's "invalid-version-es." When processing "#version 110 es",

then properly determined that this was invalid and flagged an error.

While here, also do an effective clamp (after half subtraction)

Subsequently, commit 998d975e3 change the "|| test" to a "-a"

"x$enable_dri" = xyes' clause have no effect, (as it was inside an
enclosing test for the same condition). So the new breakage from
commit 67ef7559 was addressed, but the original problems were

The immediately preceding commit removed the redundant condition.
Now, finally this commit fixes the original problem as described in

using the DRI state tracker. In order to do so, the HAVE_*_DRI
conditionals must be moved after the last assignment of HAVE_COMMON_DRI.

Pre-Haswell hardware doesn't support an arbitrary restart index, and
instead compares the index buffer value against 0xFF for byte-size
buffers, 0xFFFF for short-size buffers, or 0xFFFFFFFF for unsigned
integer buffers.
OpenGL allows the restart index to be an arbitrary unsigned integer.
When comparing against byte/short types, the index buffer value should
be promoted to a full 32-bit integer before doing the comparison. The
restart index is /not/ supposed to be masked to byte/short size.
This means that with certain restart indexes, the comparison should
always fail. For example, a restart index of 0xF000FFFF should never
match any byte/short index buffer values due to the extra high bits.
We must not enable hardware primitive restart in such a case. For now,
fall back to software primitive restart as it's the simplest fix. In
the future, we could detect restart indexes that will never match and
skip both hardware and software primitive restart.

with this name, it still showed up in the list.
The code that updates the ctx->Array._RestartIndex derived state mashed
it to 0xFFFFFFFF when GL_PRIMITIVE_RESTART_FIXED_INDEX was enabled
regardless of the index buffer type. It's supposed to be 0xFF for byte,
0xFFFF for short, or 0xFFFFFFFF for integer types.
The new _mesa_primitive_restart_index() helper gets this right.
The hardware appears to compare against the full 32-bit value some of
the time, causing primitive restart not to occur when it should. The
fact that it works some of the time is rather frightening.

All of the GLSL specs from GLSL 1.30 (and GLSL ES 3.00) onward contain
language requiring certain integer variables to be declared with the
"flat" keyword, but they differ in exactly *when* the rule is
enforced:
(a) GLSL 1.30 and 1.40 say that vertex shader outputs having integral
type must be declared as "flat". There is no restriction on fragment
shader inputs.
(b) GLSL 1.50 through 4.30 say that fragment shader inputs having
integral type must be declared as "flat". There is no restriction on
vertex shader outputs.
(c) GLSL ES 3.00 says that both vertex shader outputs and fragment
shader inputs having integral type must be declared as "flat".
Previously, Mesa's behaviour was consistent with (a). This patch
makes it consistent with (b) when compiling desktop shaders, and (c)
when compiling ES shaders.
Rationale for desktop shaders: once we add geometry shaders, (b) really
seems like the right choice, because it requires "flat" in just the
situations where it matters. Since we may want to extend geometry
shader support back before GLSL 1.50 (via ARB_geometry_shader4), it
seems sensible to apply this rule to all GLSL versions. Also, this
matches the behaviour of the nVidia proprietary driver for Linux, and
the expectations of Intel's oglconform test suite.
Rationale for ES shaders: since the behaviour specified in GLSL ES
3.00 matches neither pre-GLSL-1.50 nor post-GLSL-1.50 behaviour, it
seems likely that this was a deliberate choice on the part of the GLES
folks to be more restrictive. Also, the argument in favor of (b)
doesn't apply to GLES, since it doesn't support geometry shaders at
all.
Some discussion about this has already happened on the Mesa-dev list.

commit 3998f8c6b5
Author: Ralf Jung <post@ralfj.de>
Date: Tue Apr 9 14:09:50 2013 +0200
egl/x11: Fix initialisation of swap_interval
This little code snippet near the bottom of dri2_add_config,
if (double_buffer) {
...
conf->base.MinSwapInterval = dri2_dpy->min_swap_interval;
conf->base.MaxSwapInterval = dri2_dpy->max_swap_interval;
}
it never did what it claimed to do. The assignment never changed the value
of conf->base.MaxSwapInterval, because dri2_dpy->max_swap_interval was,
until the above exposing commit, unitialized here. That is,
conf->base.MaxSwapInterval was 0 before and after assignment. Ditto for
the min swap interval.
Above the troublesome code snippet, the call to _eglFilterArray rejects
the config as unmatching if its swap interval bounds differ from the base
config's. Before the exposing commit, at the call to _eglFilterArray, the
swap interval bounds were always [0,0], and hence no config was rejected
due to swap interval.
After the exposing commit, _eglFilterArray incorrectly rejected some
configs, which prevented dri2_egl_config::dri_double_config from getting
set for the rejected config, which resulted in a NULL pointer getting
passed into dri2CreateNewDrawable, and then segfault.
The solution: set the swap interval bounds before _eglFilterArray.

According to the Ivybridge PRM, Volume 4 Part 1, page 130, in the

and the r gradients are ignored by hardware."
This doesn't match GLSL, which provides gradients for all of the
coordinates. So we would need to do some math to compute the face ID
before using sample_d. We currently don't have any code to do that.
However, we do have a lowering pass that converts textureGrad to
textureLod, which solves this problem. Since textureGrad on three
components is sufficiently obscure, it's not a performance path.

(cherry picked from commit e2f887b243)
Consider the following shader:
vec4 f(vec4 v) { return v; }
vec4 f(vec4 v);
The prototype exactly matches the signature of the earlier definition,
so there's absolutely no point in it. However, it doesn't appear to
be illegal. The GLSL 4.30 specification offers two relevant quotes:
"If a function name is declared twice with the same parameter types,
then the return types and all qualifiers must also match, and it is the
same function being declared."
"User-defined functions can have multiple declarations, but only one
definition."
In this case the same function was declared twice, and there's only one
definition, which fits both pieces of text. There doesn't appear to be
any text saying late prototypes are illegal, so presumably it's valid.
Unfortunately, it currently triggers an assertion failure:
ir_dereference_variable @ <p1> specifies undeclared variable `v' @ <p2>
When we process the second line, we look for an existing exact match so
we can enforce the one-definition rule. We then leave sig set to that
existing function, and hit sig->replace_parameters(&hir_parameters),
unfortunately nuking our existing definition's parameters (which have
actual dereferences) with the prototype's bogus unused parameters.
Simply bailing out and ignoring such late prototypes is the safest
thing to do.

When a varying is consumed by transform feedback, but is not used by
the fragment shader, assign_varying_locations() sets its interpolation
type to "flat" in order to ensure that lower_packed_varyings never has
to deal with non-flat integral varyings (the GLSL spec doesn't require
integral vertex outputs to be flat if they aren't consumed by the
fragment shader).
A similar situation will arise when geometry shader support is added,
since the GLSL spec only requires integral vertex shader outputs to be

To minimize the variety of type conversions that lower_packed_varyings
needs to perform, it assumes that integral varyings are always
qualified as "flat". link_varyings.cpp takes care of ensuring that
this is the case (even in the circumstances where GLSL doesn't require
it).
This patch documents the assumption with an assertion, for ease in
future debugging.

Commit dfb57e7 (glsl: Fix error checking on "flat" keyword to match
GLSL ES 3.00, GLSL 1.50) relaxed the rules for integral varyings: they
only need to be declared as "flat" if they are a fragment shader
inputs. This allowed for the possibility of a vertex shader output
being a non-flat integer, provided that it was not matched to a
fragment shader input. A non-contrived situation where this might
arise is if a vertex shader generates some integral outputs which are
consumed by tranform feedback, but not by the fragment shader.
Unfortunately, lower_packed_varyings assumes that *all* integral
varyings are flat, regardless of whether they are consumed by the
fragment shader. As a result, attempting to create a non-flat
integral vertex output of a size that required packing (i.e. a size
other than ivec4 or uvec4) would cause an assertion failure in
lower_packed_varyings.
This patch prevents the assertion failure by forcing vertex shader
outputs to be "flat" whenever they are not consumed by the fragment
shader. This should have no effect on rendering since the "flat"
keyword only affects the behaviour of fragment shader inputs.

Gen4-6 and 2 for Gen7). Also a lot of logic for determining the
appropriate buffer setup was duplicated between the Gen4-6 and Gen7
functions.
This refactor splits the code into three separate functions:
brw_emit_depthbuffer(), which determines the appropriate buffer setup
in a mostly generation-independent way, brw_emit_depth_stencil_hiz(),
which emits the appropriate state packets for Gen4-6, and
gen7_emit_depth_stencil_hiz(), which emits the appropriate state
packets for Gen7.
Tested using Piglit on Gen5-7 (no regressions).
v2: Re-word some comments. Fix an assertion that incorrectly
prohibited packed depth/stencil formats on Gen6 (these are allowed
provided that HiZ is disabled).

Mesa constant-folds built-in functions by using a miniature GLSL
interpreter (see
ir_function_signature::constant_expression_evaluate_expression_list()).
This interpreter had a bug in its handling of array indexing, which
caused expressions like "m[i][j]" (where m is a matrix) to be handled
incorrectly. Specifically, it incorrectly treated j as indexing into
the whole matrix (rather than indexing just into the vector m[i]); as
a result the offset computed for m[i] was lost and m[i][j] was treated
as m[j][0].

Commit 33599433c7 began setting the texture swizzle mode to XYZ1 for
RED, RG, and RGB textures in order to force alpha to 1.0 in case we
actually stored the texture as RGBA.
This had a unforseen performance implication: the shader precompile
assumes that the texture swizzle mode will be XYZW for non-shadow
sampler types. By setting it to XYZ1, this means every shader used with
a RED, RG, or RGB texture has to be recompiled. This is a very common
case.
Unfortunately, there's no way to improve the precompile, since RGBA
textures still need XYZW, and there's no way to know by looking at
the shader source what texture formats might be used.
However, we only need to smash alpha to 1.0 if the texture's memory
format actually has alpha bits. If not, the sampler already returns 1.0
for us without any special swizzling. XRGB8888, for example, is a very
common case where this occurs.
This partially fixes a performance regression since commit 33599433c7.
More work is required to fully fix it in all cases. This at least helps
Warsow.

mask update code would drop the mask hence bringing execution back to
pixels which should have their execution mask set to zero by the ret).

In the GLSL 1.30 spec, section 4.3.6 ("Outputs") says:
"If a vertex output is a signed or unsigned integer or integer
vector, then it must be qualified with the interpolation qualifier
flat."
The GLSL ES 3.00 spec further clarifies, in section 4.3.6 ("Output
Variables"):
"Vertex shader outputs that are, *or contain*, signed or unsigned
integers or integer vectors must be qualified with the
interpolation qualifier flat."
(Emphasis mine.)
The language in the GLSL ES 3.00 spec is clearly correct and should be
applied to all shading language versions, since varyings that contain
ints can't be interpolated, regardless of which shading language
version is in use.
(Note that in GLSL 1.50 the restriction is changed to apply to
fragment shader inputs rather than vertex shader outputs, to
accommodate the fact that in the presence of geometry shaders, vertex
shader outputs are not necessarily interpolated. That will be
addressed by a future patch).

field can be either int or float or any of the sampler types, and
the precision-qualifier can be lowp, mediump, or highp."
GLSL ES 1.00 has similar language. GLSL 1.30 doesn't allow precision
qualifiers on sampler types, but this seems like an oversight (since
the intention of including these in GLSL 1.30 is to allow
compatibility with ES shaders).

Since transform feedback needs to be able to access individual fields
of varying structs, we can no longer match up the arguments to
glTransformFeedbackVaryings() with variables in the vertex shader.
Instead, we build up a hashtable which records information about each
possible name that is a candidate for transform feedback, and then
match up the arguments to glTransformFeedbackVaryings() with the
contents of that hashtable.
Populating the hashtable uses the program_resource_visitor
infrastructure, so the logic is shared with how we handle uniforms.

This patch makes it use parse_program_resource_name(), which correctly

Note that parse_program_resource_name()'s technique for handling
mal-formed input strings is to simply let them through and rely on the
fact that a future name lookup will fail. Because of this,
tfeedback_decl::init() no longer needs to return a boolean error

The parsing logic is moved to a new function in the GLSL module,
parse_program_resource_name(). This name was chosen because it should
eventually be useful for handling everything that OpenGL 4.3 calls
"program resources" (e.g. uniforms, vertex inputs, fragment outputs,
and transform feedback varyings).
Future patches will make use of this function for linking transform
feedback varyings.

Now that we have support for overriding alpha to 1.0, we can handle
blitting between these formats in either direction.
For now, we only support two XRGB formats: MESA_FORMAT_XRGB8888 and
MESA_FORMAT_RGBX8888_REV. Most places only appear to worry about the
former, so ignore the latter for now. We can always add it later.

Currently, Blorp requires the source and destination formats to be
equal. However, we'd really like to be able to blit between XRGB and
ARGB formats; our BLT engine paths have supported this for a long time.
For ARGB -> XRGB, nothing needs to occur: the missing alpha is already
interpreted as 1.0. For XRGB -> ARGB, we need to smash the alpha
channel to 1.0 when writing the destination colors. This is fairly
straightforward with blending.
For now, this code is never used, as the source and destination formats
still must be equal. The next patch will relax that restriction.

The BLT engine has many limitations. Currently, it can only blit
X-tiled buffers (since we don't have a kernel API to whack the BLT
tiling mode register), which means all depth/stencil operations get
punted to meta code, which can be very CPU-intensive.
Even if we used the BLT engine, it can't blit between buffers with
different tiling modes, such as an X-tiled non-MSAA ARGB8888 texture
and a Y-tiled CMS ARGB8888 renderbuffer. This is a fundamental
limitation, and the only way around that is to use BLORP.
Previously, BLORP only handled BlitFramebuffer. This patch adds an
additional frontend for doing CopyTexSubImage. It also makes it the
default. This is partly to increase testing and avoid hiding bugs,
and partly because the BLORP path can already handle more cases. With
trivial extensions, it should be able to handle everything the BLT can.
This helps PlaneShift massively, which tries to CopyTexSubImage2D
between depth buffers whenever a player casts a spell. Since these
are Y-tiled, we hit meta and software ReadPixels paths, eating 99% CPU
while delivering ~1 FPS. This is particularly bad in an MMO setting
because people cast spells all the time.
It also helps Xonotic in 4X MSAA mode. At default power management
settings, I measured a 6.35138% +/- 0.672548% performance boost (n=5).

Ivybridge doesn't appear to have the same errata as Sandybridge; no
corruption was observed by setting it to more than the minimal correct
value. It's possible that we were simply lucky, since the URB entries
are 1024-bit on Ivybridge vs. 512-bit Sandybridge. Or perhaps the
underlying hardware issue is fixed.
Either way, we may as well program the minimum value since it's now
readily available, likely to be more efficient, and possibly more
correct.

(This commit message was primarily written by Paul Berry, who explained
what's going on far better than I would have.)
Previous to this patch, we thought that the only restrictions on
3DSTATE_SF's URB read length were (a) it needs to be large enough to
read all the VUE data that the SF needs, and (b) it can't be so large
that it tries to read VUE data that doesn't exist. Since the VUE map
already tells us how much VUE data exists, we didn't bother worrying
about restriction (a); we just did the easy thing and programmed the
read length to satisfy restriction (b).
However, we didn't notice this erratum in the hardware docs: "[errata]
Corruption/Hang possible if length programmed larger than recommended".
Judging by the context surrounding this erratum, it's pretty clear that
it means "URB read length must be exactly the size necessary to read all
the VUE data that the SF needs, and no larger". Which means that we
can't program the read length based on restriction (b)--we have to
program it based on restriction (a).
The URB read size needs to precisely match the amount of data that the
SF consumes; it doesn't work to simply base it on the size of the VUE.
Thankfully, the PRM contains the precise formula the hardware expects.

In the documentation for BindBufferRange, OpenGL specs from 3.0
through 4.1 contain this language:
"The error INVALID_VALUE is generated if size is less than or
equal to zero or if offset + size is greater than the value of
BUFFER_SIZE."
This text was dropped from OpenGL 4.2, and it does not appear in the
GLES 3.0 spec.
Presumably the reason for the change is because come clients change
the size of the buffer after calling BindBufferRange. We don't want
to generate an error at the time of the BindBufferRange call just
because the old size of the buffer was too small, when the buffer is
about to be resized.
Since this is a deliberate relaxation of error conditions in order to
allow clients to work, it seems sensible to apply it to all versions
of GL, not just GL 4.2 and above.
(Note that there is no danger of this change allowing a client to
access data beyond the end of a buffer. We already have code to
ensure that that doesn't happen in the case where the client shrinks
the buffer after calling BindBufferRange).
Eliminates a spurious error message in the gles3 conformance test

When possible, glCopyTexSubImage calls are performed using the

Part4, section 1.2.1.2 (Graphics Data Size Limitations):
The BLT engine is capable of transferring very large quantities of
graphics data. Any graphics data read from and written to the
destination is permitted to represent a number of pixels that
occupies up to 65,536 scan lines and up to 32,768 bytes per scan
line at the destination. The maximum number of pixels that may be
represented per scan line’s worth of graphics data depends on the
color depth.
With an RGBA32F color buffer (which has 16 bytes per pixel) this
imposes a maximum width of 2048 pixels. Other pixel formats have
accordingly larger limits.
To make matters worse, if the pitch of the buffer is 32k or greater,
intel_copy_texsubimage's call to intelEmitCopyBlit will overflow
intelEmitCopyBlit's src_pitch and dst_pitch parameters (which are
16-bit signed integers).
We can conveniently avoid both problems by avoiding use of the blitter
when the miptree's pitch is >= 32k.
Fixes gles3conform "framebuffer_blit_functionality_magnifying_blit"
tests when the buffer width is equal to 8192.
Note: this is very similar to the recent patch "intel: Fix ReadPixels

glCopyTexSubImage instead of glReadPixels. In a future patch it would
be nice to refactor the code so that (a) overflow is avoided, and (b)
intelEmitCopyBlit is responsible for checking whether the blitter can
handle the width, so that all callers of intelEmitCopyBlit work
properly, rather than just these two.

Mesa doesn't flatten varying structs to their individual components,
but this is ok, since it packs varyings of all kinds with no wasted

This patch paves the way for allowing varying structs by generalizing

matrices being packed according to the size of their columns. Now, we
pack everything according to its number of components mod 4, in the
order (0, 2, 1, 3).
There is no behavioural change for vectors. Matrices are now packed
slightly differently:
- mat2x2 gets assigned PACKING_ORDER_VEC4 instead of
PACKING_ORDER_VEC2. This is slightly better, because it guarantees
that the matrix occupies a single varying slot.
- mat2x3 gets assigned PACKING_ORDER_VEC2 instead of

a 25% chance of having neither of its columns double parked, a 50%
chance of having exactly one of its columns double parked, and a 25%
chance of having both of its columns double parked. Now it always
has exactly one of its columns double parked.
- mat3x3 gets assigned PACKING_ORDER_SCALAR instead of
PACKING_ORDER_VEC3. This doesn't affect much, since in both cases
there is no guarantee of how the matrix will be aligned.

This reverts commit 7824ab8070.
Now that we force linking with LLVM shared libs when building clover,
we can link against libgallium.la with no problems.
If we build clover with LLVM static libraries, then clover and also each
pipe_*.so driver that is built will contain their own static copy of
LLVM. The recent automake changes have uncovered a problem where
the pipe_*.so drivers try to use clover's LLVM symbols. This causes
LLVM's static registry objects to be initialized each time
a pipe_*.so driver is loaded by clover. Initializing these objects
multiple times is not allowed and leads to assertion failures in the
LLVM code.
We can avoid all these problems by having clover and all the pipe_*.so
drivers link against the same LLVM shared library.

v2:
- Fix shared library detection when LLVM is built with CMake
In order to determine which static LLVM libraries are needed we pass
a list of components to llvm-config and it generates the list of
library dependencies for us. The advantage of only calling llvm-config
one time is that it can determine if two components depend on the same
library and then add it to the output list only once. The old practice
of having each driver call llvm-config to add its own dependencies to
$(LLVM_LIBS) caused many libraries to be added to this variable multiple
times.
Always enable the use of pre-compressed texture data. The ability to
perform on-line compression still requires the presence of libtxc_dxtn
or an explicit driconf over-ride. Applications that just want to submit
precompessed data when an on-line compressor is not available can look
for the GL_EXT_texture_compression_dxt1 and
GL_ANGLE_texture_compression_dxt[35] extensions.
v2: Only enable the extensions that do not require on-line compression
by default. The previous statement "This should not impact many (if
any) real applications." proved to be false for at least Sauerbraten.

The renderbuffer's Format field may have an alpha channel even when the
underlying _BaseFormat does not. This can happen when mesa chooses to use
RGBA16 for an RGB16 format, for example.
So look at _BaseFormat when deciding whether to fixup the blend factors.
This test improves the results of at least the following piglit tests:
EXT_frambebuffer_object/fbo-blending-formats
{GL_RGB10, GL_RGB12, GL_RGB16}
EXT_texture_snorm/fbo-blending-formats

There are also bad interactions with multisampling and OpenGL ES 3.0.
In ES3, a multisample-to-singlesample blit must have identical source

RGB8 (window) blit will generate an error. Also in ES3, RGB8 is not a
renderable format. This means that the application CANNOT make an RGB8
multisample renderbuffer.
As a result, if an application gets an RGB8 window and wants to do

r600g: add in-place DB decompression and texturing with DB tiling
The decompression is done in-place and only the compressed tiles are
decompressed. Note: R6xx-R7xx can do that only with Z16 and Z32F.
The texture unit is programmed to use non-displayable tiling and depth
ordering of samples, so that it can fetch the texture in the native DB format.
The latest version of the libdrm surface allocator is required for stencil
texturing to work. The old one didn't create the mipmap tree correctly.
We need a separate mipmap tree for stencil, because the stencil mipmap
offsets are not really depth offsets/4.
There are still some known bugs, but this should save some memory and it also
improves performance a little bit in Lightsmark (especially with low
resolutions; tested with Radeon HD 5000).
The DB->CB copy is still used for transfers.

'layout(row_major) vec4 foo' is probably not what the programmer meant.
The only catch is dealing with structures that contain matrices. Layout
qualifiers cannot be applied directly to fields of structures, so the
only way to affect the layout of the fields is to apply a qualifier to
the structure declaration itself. There is ongoing debate about this
within Khronos, and it seems to be settling in favor of allowing the
qualifiers on structures. I light of this, I have chosen to allow the

"For one-, two-, and three-dimensional and one-and two-dimensional array
textures, a texture is mipmap complete if all of the following
conditions hold true:
- [...]
- levelbase <= levelmax [...]
Using the preceding definitions, a texture is complete unless any of
the following conditions hold true:
- [...]
- The minification filter requires a mipmap (is neither NEAREST nor
LINEAR), and the texture is not mipmap complete."
(This text also appears in all GL >= 3.2 specs and the ES 3.0 spec.)
From this, we see that levelbase <= levelmax should only affect mipmap
completeness, not base-level completeness.

Writemask was XY instead of YZ (thanks to calim for spotting it).
The pixel calculation resulted in the pixel always being off by one.
If y was .5:
y' = round(y) + 0.5 = 1.5
Fixing this also means the LRP function has to swap the pixels it, since
it's now the other way around for top/bottom.

Before this patch, intelInitScreen2 set DRIScreen::api_mask with the hacky
heuristic below:
if (gen >= 3)
api_mask = GL | GLES1 | GLES2;
else
api_mask = 0;
This hack was likely broken on gen2 (i830), but I don't care enough to
properly investigate. It appears that every EGLConfig on i830 has
EGL_RENDERABLE_TYPE=0, and thus eglCreateContext will never succeed.
Anyway, moving on to living drivers...
With the arrival of EGL_OPENGL_ES3_BIT_KHR, this heuristic is now
insufficient. We must enable the GLES3 bit if and only if the driver is
capable of creating a GLES3 context. This requires us to determine the
maximum supported context version supported by the hardware/driver for
each api *during initialization of intel_screen*.
Therefore, this patch adds four new fields to intel_screen which indicate
the maximum supported context version for each api:
max_gl_core_version
max_gl_compat_version
max_gl_es1_version
max_gl_es2_version
The api mask is now correctly set as:
api_mask = GL;
if (max_gl_es1_version > 0)
api_mask |= GLES1;

According to both the GL 3.0 and ES 3.0 specifications (table 2.7 for GL
and table 2.8 for ES), the default value of BUFFER_ACCESS_FLAGS is
supposed to be zero.
Note that there are two related quantities: the obsolete BUFFER_ACCESS
enum and the new BUFFER_ACCESS_FLAGS bitfield.
BUFFER_ACCESS can only be GL_READ_ONLY, GL_WRITE_ONLY, or GL_READ_WRITE;
BUFFER_ACCESS_FLAGS can easily represent all three via GL_MAP_WRITE_BIT,
GL_MAP_READ_BIT, and their logical or. It also supports more flags.
Thus, Mesa only stores the bitfield, and simply computes the old enum
when queried, via simplified_access_mode(bufObj->AccessFlags).
The tricky part is that, while BUFFER_ACCESS_FLAGS defaults to 0,
BUFFER_ACCESS defaults to GL_READ_WRITE for desktop [GL 3.0, table 2.8]
and GL_WRITE_ONLY_OES for ES [the GL_EXT_map_buffer_range extension].
Mesa tried to implement this by setting the default AccessFlags to
GL_MAP_READ_BIT | GL_MAP_WRITE_BIT on desktop, and GL_MAP_WRITE_BIT on
ES. But in all specifications, it needs to be 0.
This patch moves that logic into simplified_access_mode(): when
AccessFlags == 0, it now returns GL_READ_WRITE for desktop and
GL_WRITE_ONLY for ES 1/2. (BUFFER_ACCESS doesn't exist on ES 3.0,
so it's irrelevant there.)
With that in place, it changes the AccessFlags default to 0.

MSAA can't be made any faster as far as hw programming is concerned.
The catch is only one process and one colorbuffer can use the optimizations
at a time. There usually is only one MSAA colorbuffer, so it shouldn't be
an issue.
Also, there is a limit on the size of MSAA colorbuffer resolution in terms
of megapixels. If the limit is surpassed, the AA optimizations are disabled.
The limit is:

- 2 Mpix on some mid-level chipsets (1600x1200 and 1920x1080)
- 3 or 4 Mpix on high-end chipsets (2048x1536 or 2560x1600, respectively)
It corresponds to the number of raster pipes (= GB pipes) available, each pipe

According to bug #54524, I regressed oglconform's multicontext test
when I reenabled the fragment shader precompile.
However, these test cases only passed by miraculous coincedence. We
assign each fragment program a unique ID (brw_fragment_program::id which
becomes brw_wm_prog_key::program_string_id) which we obtain by storing a
per-context counter.
The test case uses GLX context sharing to access the same fragment
program from two different contexts. This means that we share a program
cache. Before the precompile, if both contexts happened to use the same
shaders in the same order, we'd obtain the same program_string_ids (by
virtue of doing the same computation twice). However, the more likely
scenario is that they completely disagree on program_string_id.
This meant that we'd have two completely different fragment shaders in
the cache with the same ID, tricking us to think they were the same
(aside from NOS), so we'd render using the wrong program.
This patch implements a simple fix suggested by Eric: it moves the
global counter out of brw_context and into intel_screen, which is shared
across all contexts. A mutex protects it from concurrent access.
This is also the first direct usage of pthreads in the i965 driver.

redacted to be optional in C11, and not actually part of C++ whatsoever.
Gcc allows using them in C++ unless you specify -pedantic, and Clang
appears to allow them for simple/POD types.
exec_list is arguably POD, since it doesn't have virtual methods, but I
can see why Clang would be like "meh, it's a C++ struct, say no", seeing as
it's meant to support C99.

Previously this was happening unconditionally, leading to some excessive
rebuilding/relinking during builds.
Note that the .po files are not automatically updated due to changes to the
t_options.h file. Instead, translators should continue to use "make po"
manually. This is because after new strings are merged into the existing .po
file, manual work is still required by translators to ensure that the
translations are correct.
Previously, the xmlpool directory had a lone Makefile to assist poeple in
manually invoking a deep make in order to update the translations in
options.h. We can observe that this wasn't happening in fact, (new
translations had been added to de.po without being generated into options.h,
and new options had been manually added directly to options.h rather than to
t_options.h).
Prevent both of these problems from occurring in the future by automatically
generating options.h as part of the standard build of mesa.
For this, the generated options.h is now removed from version control, (along
with Makefile in favor of Makefile.am).

In most cases, the width, height, and depth of the physical surface
used by the driver to implement a texture or renderbuffer is equal to
the logical width, height, and depth exposed to the client through
functions such as glTexImage3D(). However, there are two exceptions:
cube maps (which have a physical depth of 6 but a logical depth of 1)
and multisampled renderbuffers (which have larger physical dimensions
than logical dimensions to allow multiple samples per pixel).
Previous to this patch, we accounted for the difference between
physical and logical surface dimensions at inconsistent places in the
call graph (multisampling was accounted for in
intel_miptree_create_for_renderbuffer(), and cubemaps were accounted
for in intel_miptree_create_internal()). As a result, it wasn't
always clear, when calling a miptree creation function, whether
physical or logical dimensions were needed. Also, we weren't
consistent about storing logical dimensions in the intel_mipmap_tree
structure (we only did so in the
intel_miptree_create_for_renderbuffer() code path, and we did not
store depth).
This patch refactors things so that intel_miptree_create_internal() is
responsible for converting logical to physical dimensions and for
storing both the physical and logical dimensions in the
intel_mipmap_tree structure. As a result, all miptree creation
functions interpret their arguments as logical dimensions, and both
physical and logical dimensions are always available to functions that
work with intel_mipmap_trees.
In addition, it renames the fields in intel_mipmap_tree used to store
the dimensions, so that it is clear from the name whether physical or
logical dimensions are being referred to.
This should fix the following bugs:
- When creating a separate stencil surface for a depthstencil cubemap,
we would erroneously try to convert the depth from 1 to 6 twice,
resulting in an assertion failure.
- When creating an MCS buffer for compressed multisampling, we used
physical dimensions instead of logical dimensions, resulting in
wasted memory.
In addition, this should considerably simplify the implementation of
ARB_texture_multisample, because it moves the code to compute the
physical size of multisampled surfaces out of renderbuffer-only code.

This is not as optimized as r600g - the MSAA compression is missing,
