[Mesa-dev] [ANNOUNCE] Mesa 18.0.1 release candidate

Sun Apr 15 20:01:03 UTC 2018

Hello list,

The candidate for the Mesa 18.0.1 is now available. Currently we have:
 - 46 queued (+2 squashed)
 - 0 nominated (outstanding)
 - and 2 rejected patches

The current queue consists of:

On the build system to highlight Meson is get improved thorugh several patches
that fix issues around it.

On the drivers part, RADV get several fixes: one for multisample regressions on
Vega, another around GFX9 buffer views, and a couple of them more to related
with avoiding emitting unneeded vertex state.

St/Nine get fixes around face register, lighting constants, math check for
inversible matrix, implicit conversions and bad tracking of vertex textures.

Freedreno/a5xx get fixes around missaligned heigh for PIPE_BUFFER, and around
page faults.

Several fixes are also enqueued for Intel driver: set right channel_sizes for
MOV_INDIRECT sources, set right config registration for uploading to kernel,
return the fourcc stored in __DRIimage when possible, fix negative sign in
64-bit return values, fix null destination register in assembly instructions
with 3 source operands, a fix for failed TCS/TES shader compilation

Queue also contains a couple of fixes around Gallium drivers, one to fix a typo
in code that was causing wrong return value, and another one to fix an
unitialized modifier for DRI2.

Mesa core gets a couple of patches to fix issues around overriding OpenGL/ES
supported version through environment variables, and a patch to fix an issue
with texture samples found in "The Witness" through Wine.

A couple of bugs around unrolling loops have also been fixed, these patches were
applied for NIR and GLSL.

On top of above, NIR gets more fixes in a couple of lowering functions used:
coalesce in lower_vec_to_movs if vec had a SSA destination, and interp_var_at
intrinsic support in lower_indirect_derefs. It also gets a fix around
vars_to_ssa function.

Finally, there are other fixes affecting Radeonsi, AC, EGL/Wayland and SPIR-V
compiler.

Take a look at section "Mesa stable queue" for more information.

Testing reports/general approval
--------------------------------
Any testing reports (or general approval of the state of the branch) will be
greatly appreciated.

The plan is to have 18.0.1 this Wednesday (18th April), around or shortly after 11:00
GMT.

If you have any questions or suggestions - be that about the current patch queue
or otherwise, please go ahead.

Rejected (2)
=============

Dave Airlie (1):
      8f052a3e25 radv: handle exporting view index to fragment shader. (v1.1)

Reason: Nominated through "Fixes" tag, the commit requires earlier commits
639c4f2b54a6 and 2cfba40eea4c which did not land in branch.

Jason Ekstrand (1):
      85d0bec961 anv: Be more careful about fast-clear colors

Reason: this patch does not apply cleanly, as it depends on other commits not
not in the branch. And there is a backport that it is causing regressions.
