Clang 10 + Linux 5.6 Will Be Able To Build A Working s390 Kernel

With LLVM Clang 9.0 and Linux 5.3 together it became possible to build the mainline Linux kernel with this non-GCC compiler. The x86_64 Linux kernel Clang-based kernel builds has continued to improve through newer kernel releases. This follows the mainline AArch64 (64-bit ARM) Linux kernel mainline build by Clang too, which has been of much interest by different hardware/software vendors. There hasn't been much Clang'ing kernel efforts for other architectures, but it turns out with Clang 10 and Linux 5.6 will be another working combination, this time for IBM s390.

Linux 5.5 Required More Deblobbing Than Usual For GNU Linux-libre 5.5

Fresh off the Linux 5.5 release, the Free Software Foundation Latin America crew has debuted their GNU Linux-libre 5.5 downstream that continues to be focused on deblobbing the kernel of drivers requiring proprietary firmware and stripping out other code/functionality that is contingent upon non-free software bits and removing the ability to load closed-source kernel modules.

Linux 5.6 "HWMON" Changes Sent In With Big AMD Improvements

Following the Linux 5.5 kernel release one of the first pull requests sent in is for the hardware monitoring "HWMON" subsystem updates. Dominating the HWMON interest this cycle is a long overdue SATA temperature monitoring driver and vastly improving the k10temp driver for AMD Zen desktop and server CPUs.

Linux 5.6 Is Looking Like It Will Be Spectacular With A Long List Of Features

Linux 5.5 is likely to be released later today and with that are many new features. But as soon as 5.5 is released it marks the opening of the Linux 5.6 merge window and this next kernel has us particularly exciting... It's certainly shaping up to be one of the most exciting kernel cycles in recent times with many blockbuster features and improvements.

Torvalds' Comments On Linux Scheduler Woes: "Pure Garbage"

As you may recall a few days ago there was the information on the Linux kernel scheduler causing issues for Google Stadia game developers. The scheduler was to blame and in particular Linux's spinlocks. Linus Torvalds has now commented on the matter.

The Linux Kernel's Scheduler Apparently Causing Issues For Google Stadia Game Developers

Among the issues that game developers have been facing in bringing their games to Linux for Google's Stadia cloud gaming service apparently stem from kernel scheduler issues. We've known the Linux kernel scheduler could use some improvements and independent developers like Con Kolivas with BFS / MuQSS have pushed for such, but hopefully in 2020 we'll see some real action.

The AppArmor Performance Impact In 70+ Benchmarks On Linux 5.5 Git

With bisecting one of the big regressions in Linux 5.5 and finding the culprit to be an AppArmor change while using Hackbench as one of the most affected tests, I was curious to see what other workloads are impacted big by AppArmor on the current Linux 5.5 Git code. Here are 72 tests with the Threadripper 3970X on Linux 5.5 Git when toggling AppArmor.
