*YP 3.1.9 has been through QA and is awaiting release approval, no blocking issues were identified.
*YP 3.1.9 was released.
*YP 3.4 M1 was released.
*The prserv rewrite is still pending on resolving the issues with python asyncio.
*Significantly for the project, we have now identified a kernel hang caused from RCU stalls which has been plaguing our autobuilder testing for months. The issue is still open in upstream mainline kernels but there is a patch queued in the rcu tree for it. Since applying this patch to linux-yocto, our builds have been noticeably greener and more stable. We have closed out many of the related AB-INT bugs and will be creating new ones for any remaining issues as they occur since it is hard to tell some other bugs apart from the RCU issue.
*Alexandre Belloni/Bootlin have been taking over some of the patch testing/queuing work over the last couple of weeks, feedback to either Richard/Alexandre or the TSC on how this is working is welcome.
*The prserv rewrite to use asyncio is stuck on autobuilder hangs when testing at larger scale. We’d welcome help from anyone with more details asyncio knowledge/experience as it is looking like the new code isn’t entirely stable in python 3.5/3.6 and may have “at exit” issues, as well as perhaps issues mixing async io code on the client side with multiprocessing during parsing.
*Intermittent autobuilder issues continue to occur, about 50% of the open issues are now ptest failures, many occurring more frequently on arm and the rest are various other races or timeouts. You can see the list of failures we’re continuing to see by searching for the “AB-INT” tag in bugzilla: https://bugzilla.yoctoproject.org/buglist.cgi?quicksearch=AB-INT
*There does still seem to be an arm specific LTP hang reading /proc/kmsg now tracked by bug 14460.
*We have made progress on a couple of the race issues and on one of the ptest issues (util-linux), some of the ptest issues and the bitbake server timeout issue are now our most frequently encountered issues.
*The multiconfig changes in bitbake continue to cause problems, we still need simpler test cases to reproduce issues rather than huge builds. The existing patches seem to fix some workloads and break others. Richard is trying to fix but trying to fix autobuilder issues and other problems and these are slow builds to debug.
*A rootfs license race issue (#14123) now has reproduction steps which should allow a fix to follow.
