Don't Look For Gentoo's CPU Optimization Options To Land In The Mainline Linux Kernel

Filed under
Linux
Gentoo

Gentoo's Linux kernel build has long offered various CPU options in allowing those building their distribution to optimize their kernel build to the CPU being used. Every so often the patch is suggested for upstreaming to the mainline Linux kernel before being quickly rejected by the upstream maintainers.

This week the kernel CPU options patch was suggested for mainlining in the Linux kernel. The patch adds extra CPU options to the kernel configuration (Kconfig) area for adjusting the GCC optimization values for various generations of Intel/AMD CPUs. It allows building the kernel ranging from -march=k8-sse3 to -march=cannonlake, among other prominent generations of Intel/AMD processors over the years.

How App Stores Are Addressing Fragmentation in the Linux Ecosystem

According to DistroWatch, 273 Linux distributions are currently active, with another 56 dormant and 521 discontinued. While some of these have shared underpinnings, it still makes for an extremely varied landscape for companies and developers. It means developers must create multiple versions of their applications to be able to provide their software to all Linux users or just address a fraction of the market. Also, developers require multiple versions of build tools, which inevitably results in significant resource overhead. Desktop application distribution is complex across all operating systems in general; in Linux, this is further compounded by such fragmentation and inter-dependencies both in the packaging and distribution of software. For example, Fedora uses the RPM packaging format, while Debian uses the .deb format. Moreover, packages built for one version of a Linux distribution are often incompatible with other versions of the same distribution and need to be built for each version separately. Read more
