Linux 5.12-rc1
So two weeks have passed since the 5.11 release, and so - like clockwork - the merge window for 5.12 has closed, and 5.12-rc1 is out there for your perusal. That said, we have now have two unusual merge windows in a row: first we had the holiday season, and this time around the Portland area had over a quarter million people without electricity because we had a winter ice storm that took down thousands of trees, and lots of electricity lines. So I was actually without electricity for six days of the merge window, and was seriously considering just extending the merge window to get everything done. As you can tell, I didn't do that. To a large part because people were actually very good about sending in their pull requests, so by the time I finally got power back, everything was nicely lined up and I got things merged up ok. But partly this is also because 5.12 is a smaller release than some previous ones - and that wasn't due to the lack of electricity, that showed independently in the statistics in the linux-next tree. Of course, "smaller" is all relative, but instead of the 12-13+k commits we've had the last few releases, linux-next this time only had 10+k commits lined up. So that helped things a bit. That said, if my delayed merging caused issues for anybody, please holler and explain to me, and I'll be flexible during the rc2 week. But that's _not_ a blanket "I'll take late pulls", that's very much a "if my delayed merge caused problems for some tree, explain why, and I'll work with you". Anyway, on to the actual changes. Even if it was a slightly smaller merge window than previous ones, it's still big enough that appended is just my usual merge log, not the full list of the 10982 non-merge commits by 1500+ people. So it's more of a flavor of the kinds of things that have happened rather than a deep dive. The one thing that perhaps stands out is that this release actually did a fair amount of historical cleanup. Yes, overall we still have more new lines than we have removed lines, but we did have some spring cleaning, removing the legacy OPROFILE support (the user tools have been using the "perf" interface for years), and removing several legacy SoC platforms and various drivers that no longer make any sense. So even if we more than made up for that with all the _new_ drivers and code we added, that kind of cleanup is always nice to see. Linus

Samsung, Red Hat to Work on Linux Drivers for Future TechThe metaverse is expected to uproot system design as we know it, and Samsung is one of many hardware vendors re-imagining data center infrastructure in preparation for a parallel 3D world. Samsung is working on new memory technologies that provide faster bandwidth inside hardware for data to travel between CPUs, storage and other computing resources. The company also announced it was partnering with Red Hat to ensure these technologies have Linux compatibility. |
