Linus has released the 5.2-rc2 kernel prepatch and closed the merge window for this development cycle. "Nothing particularly odd going on this merge window. I had some travel in the middle of it, but to offset that I had a new faster test-build setup, and most of the pull requests came in early (thank you) so my travels didn't actually end up affecting the merge window all that much."

[$] Testing in the Yocto Project

The ever-increasing complexity of the software stacks we work with has given testing an important role. There was a recent intersection between the automated testing being done by the Yocto Project (YP) and a bug introduced into the Linux kernel that gives some insight into what the future holds and the potential available with this kind of testing.

Coverage from the Python Language Summit

Over the past four years, LWN has covered the Python Language Summit, but this year the Python Software Foundation (PSF) elected to go in a different direction, with coverage by A. Jesse Jiryu Davis on the PSF blog. Those reports are being gathered on a summit page; as of this writing there are two reports up with plenty more to come. "The Python Language Summit is a small gathering of Python language implementers, both the core developers of CPython and alternative Pythons, held on the first day of PyCon. The summit features short presentations from Python developers and community members, followed by longer discussions. The 2019 summit is the first held since Guido van Rossum stepped down as Benevolent Dictator for Life, replaced by a five-member Steering Council."

[$] Telling the scheduler about thermal pressure

Thu May 16 16:26:00 2019

Even with radiators and fans, a system's CPUs can overheat. When that happens, the kernel's thermal governor will cap the maximum frequency of that CPU to allow it to cool. The scheduler, however, is not aware that the CPU's capacity has changed; it may schedule more work than optimal in the current conditions, leading to a performance degradation. Recently, Thara Gopinath did some research and posted a patch set to address this problem. The solution adds an interface to inform the scheduler about thermal events so that it can assign tasks better and thus improve the overall system performance.

Last 3.18.x stable release: 3.18.140

Greg Kroah-Hartman has announced the release of the 3.18.140 stable kernel. "Note, this is the LAST 3.18.y release that I will be doing on kernel.org. I know it has been marked as End-of-Life for quite some time, but I have kept it alive due to a few million phones out there in the wild that depend on it, and can not move to a new kernel base due to them being stuck with a SoC vendor that does not work upstream. But, this does not mean the tree is dead, oh no, if only it were that easy..." He and others will be updating the kernel in the Android Open Source Project (AOSP) tree.

[$] A panel with the new Python steering council

Wed May 15 21:04:00 2019

Over the past year, Python has moved on from the benevolent dictator for life (BDFL) governance model since Guido van Rossum stepped down from that role. In February, a new steering council was elected based on the governance model that was adopted in December. At PyCon 2019 in Cleveland, Ohio, the five members of the steering council took the stage for a keynote panel that was moderated by Python Software Foundation (PSF) executive director Ewa Jodlowska.
