Detailing The Idle Loop Ordering Problem & The Power Improvement In Linux 4.17

Of the many great features/changes for Linux 4.17, one of the most exciting to us is the idle power efficiency and performance-per-Watt improvements on some systems thanks to a rework to the kernel's idle loop handling. Rafael Wysocki and Thomas Ilsche as two of the developers working on this big code change presented on their work today for this CPU idle loop ordering problem and its resolution.

Matthew Garrett Elaborates More On Lockdown + Secure Boot Pairing

A few days back we covered the heated exchange on the kernel mailing list over the path being pursued by the Linux kernel "lockdown" patches. Those back and forth messages between Google's Matthew Garrett and Linus Torvalds have now spilled over into a blog post by Garrett.

Linux 4.17's Staging Area Loses Some Weight

While the Linux 4.17 kernel is getting much larger in some areas like the sizable additions to DRM this cycle, when it comes to the kernel's staging area where new/experimental code gets vetted before being officially mainline, it's lost tens of thousands of lines of code this cycle.

The Big DRM Pull Request Made It Into Linux 4.17

Last week David Airlie sent in the big DRM feature update for Linux 4.17 prior to going on holiday. For those wondering whether there was going to be any drama with the DRM updates increasing the size of the Linux kernel by another one hundred thousand lines of code, in large part due to Vega 12 header additions, Linus pulled it in without any fuss.

Torvalds Expresses Concerns Over Current "Kernel Lockdown" Approach

The kernel lockdown feature further restricts access to the kernel by user-space with what can be accessed or modified, including different /dev points, ACPI restrictions, not allowing unsigned modules, and various other restrictions in the name of greater security. Pairing that with UEFI SecureBoot unconditionally is meeting some resistance by Linus Torvalds.
