The commit below exposed a bug in dri2_add_config.
commit 3998f8c6b5

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
section for the sample_d message: "The r coordinate contains the faceid,
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.
For now, only handle samplerCubeShadow; we need tests for samplerCube
and samplerCubeArray.

(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.

Running piglit with this was causing all sort of weird stuff happening
to my desktop (Chromium webpages become blank, Qt Creator flickered,
etc). I tracked this down to shared memory segment leakage when GL is
not shutdown properly. The segments can be seen running `ipcs` and
looking for nattch==0.
This changes fixes this by calling shmctl(IPC_RMID) soon after creation
(which does not remove the segment immediately, but simply marks it for
removal when no more processes are attached).
This matches src/mesa/drivers/x11/xm_buffer.c behaviour.

Inserting the value for the second quad in the wrong place for the

quite catastrophic, can lead to bogus texels fetched or just segfault.
This code is only hit for SoA path currently, still surprising it
didn't crash more or caused more visible issues (I think llvm used a
broadcast shuffle for the undefined parts of the vector, hence the undefined
value for the second quad was just the same as that from the first quad,
so as long as both quads hit the same mip level everything was fine, and since
lower mips always have the same large stride it made it less likely to

In the mailing list discussion of "glsl/linker: fix varying packing

since the bug only applies to integral variables, it is safer to just
apply the bug fix to integer varyings. I forgot to make the change
before pushing the patch upstream. (Note: we aren't aware of any bugs
in commit 7862bde; it just seems wise to be on the safe side).

(cherry picked from commit 5306af2113)
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
flat when they are consumed by the fragment shader. This patch
modifies the linker to handle this situation too.

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.

5 chunks of code for emitting the _3DSTATE_DEPTH_BUFFER packet (3 for
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

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.
