Comment 3 Ben Crocker 2017-09-16 20:59:04 EDT

The fix for this problem is embodied in the following Mesa commits:

commit 75cb6e36178b9474bbb59b76cbbcce2a67bf88d2
Author: Ray Strode <rstrode@redhat.com>
Date:   Wed Aug 23 16:32:42 2017 -0400

    gallivm: correct channel shift logic on big endian


commit 57c8ead0cd08e6aaf88a389f7ce528c4f0face65
Author: Ben Crocker <bcrocker@redhat.com>
Date:   Wed Aug 23 16:32:43 2017 -0400

    llvmpipe: lp_build_gather_elem_vec BE fix for 3x16 load

These commits do NOT appear to be in any of the Mesa
17.2.0 release candidates; we will need to do one of the following:

1) Apply these changes as a patch to 17.2;
2) Convince the Mesa folks to spin one more release candidate
   with this patch (seems unlikely, as Andres Gomez asserts that
   he has "completed the 17.2 cycle" with "17.2-rc6 as tentative
   final version to be promoted to 17.2.0 final."  The only
   encouraging word here is "tentative;"
3) Ship RHEL 7.5 with 17.2.1, which is not yet finalized
   (or even begun).

Comment 4 Ben Crocker 2017-09-18 10:43:56 EDT

Crossed in the mail, apparently.
According to Emil Velikov, Mesa 17.2.1 is now available(!).

Comment 5 Ben Crocker 2018-01-31 17:23:57 EST

The version of Mesa supplied with RHEL 7.5 is actually 17.2.2 or greater;
since the fixes for this problem were in Mesa 17.2.1, this BZ should 
be closed.
