Bug Description

[Impact]

A new upstream bugfix release is available. Release note diff compared to 17.2.4:

Mesa 17.2.5 is now available.

In this release we have:

In Mesa Core a GL error related to the ARB_ES3_1_compatibility spec
noticed with the GFXBench 5 Aztec Ruins has been corrected.

The GLSL compiler is not giving a linker error for mismatching uniform
precision with GLSL ES 1.00 any more. This enables, specially, several
Android applications which violate this rule, like Forge of Empires,
for example.

The SPIR-V compiler has corrected an assert triggered when support for
the simple memory model was claimed.

NIR has also received a correction related with
gl_SubGroupG{e,t}MaskARB.

The Intel drivers, specially i965, have received several fixes,
including a plug for a memory leak and another one in the compiler to
avoid GPU hangs on Broxton.

The gallium i915g driver for Intel has also seen an important
correction.

AMD drivers, mostly radv, have also received several fixes, including a
correction for a DCC corruption that was visible with Rust, breaking an
endless loop in r600, avoiding a GPU hang with vulkan dota2 in VR mode
and a plug for a memory leak.

Broadcom's vc4 has gotten a fix to compile out some non-debug code that
shouldn't be there for the release build.

----

Mesa 17.2.6 is now available.

In this release we have:

In Mesa Core we have included a correction to keep a program alive when
re-linking and prevent an use-after-free.

The GLSL compiler has received several fixes, including one to prevent
a SIGSEV when calling an undeclared subroutine in certain conditions
and another to mark the xfb buffers as active only if a variable uses
them.

The SPIR-V compiler has corrected a couple of issues involving the
usage of separate images and texture/samplers.

The Intel drivers include many new fixes, specially for i965. Several
are focused on improving SIMD32 and little-core. It also includes a fix
for a GPU hang which was detected while playing HW accelerated video
with mpv.

The AMD drivers have also received some care. radv has seen plugged 2
memory leaks while r600 has gotten a fix through reversing the tess
factor components for isolines.

The swr driver has corrected two performance regressions, one for the
avx512 platforms and the other for the avx/avx2 platforms.

In the ddebug gallium driver we have a fix for an use-after-free.

On the EGL side, the Wayland platform of the the DRI2 drivers has
received a fix to prevent crashing in ancient systems.

GLX has also received corrections to prevent a couple of errors when
creating and binding a context in DRI3 and DRISW, respectively.

From build and integration point of view, we have added some few more
fixes, including one to allow building libglvnd when EGL is present but
not GLX, another to enable building targets which don't need X11, such
as omx and va, when XCB is not present, and another one to be able to
specify the prefix installation for the OpenCL icd file.

----

Mesa 17.2.7 is now available.

In this release we have:

The current queue consists of a variety of fixes, with a sizeable hunk in the
shared GLSL codebase.

Whereas for individual drivers - i965 has a crash fix for when playing various
Valve games, r600 and nouveau have tweaks in their compiler backends. Fast
clears on radeonsi and RADV are better now, while the VAAPI encoding is playing
nicely with GStreamer.

The WGL state tracker and SWR driver have also seen minor improvements.

To top of up - Mesa should build fine with the latest glibc 2.17.

----

Mesa 17.2.8 is now available.

In this release we have:

The SPIR-V compiler has seen corrected a possible SEGFAULT.

The Intel i965 driver includes a correction for Haswell involving
doubles management.

The AMD drivers have also received some fixes. A couple have gone for
radv and radeon's VCE while r600 has seen corrected some glitches
detected with This War of Mine.

Gallium has also received a patch fixing a problem affecting the VMware
driver and the st/nine state tracker.

The endianness detection in Windows platform has been corrected to
default to little endian.

Finally, the X11 driver has been improved to notify properly a mesa
warning rather than using fprintf.

[Test case]

Test typical use cases on the most common hw/driver combinations:
intel/i965
nvidia/nouveau
radeon/radeonsi

[Regression potential]

These releases are tested against compliance, bugfix releases in particular have minimal risk of regressing anything major at least.

As per Timo's proposition, I'm publishing artful right now and after a day or two I'll release xenial if no errors are reported for the artful version. We want to play it safe as this version will be included in 16.04.4.

The libkscreen test suite is completely unreliable so ignoring that failure.
