Linus Torvalds Just Made A Big Optimization To Help Code Compilation Times On Big CPUs

For those using GNU Make in particular as their build system, the parallel build times are about to be a lot faster beginning with Linux 5.6 for large core count systems. This landing just after the AMD Threadripper 3990X 64-core / 128-thread CPU launch is one example of systems to benefit from this kernel change when compiling a lot of code and making use of many GNU Make jobs.

Linux 5.5 Performance Overall Is Comparable To Older Kernels For Most Workloads

Since the stable release of Linux 5.5 this weekend I have been carrying out benchmarks for looking at how the performance of this newly-minted kernel compares to older releases. Here are benchmark results of Linux 5.3 vs. 5.4 vs. 5.5 with an AMD Ryzen Threadripper 3970X but the results are similar to other HEDT and lower-end systems we've tested thus far.

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.
