Working on Linux 4.2 – The Kernel Column

 Linus Torvalds announced the first Linux 4.1 release candidate kernel saying, “no earth-shattering new features come to mind, even if initial support for ACPI on arm64 looks funny. Depending on what you care about, your notion of ‘big new feature’ may differ from mine, of course. There’s a lot of work all over and it might just make a big difference to your use cases.” New features in Linux 4.1 include the new ‘simple persistent memory’ driver (which enhances support for Non-Volatile Memory devices), support for single user-only systems where support for multiple users is configured out (for very small embedded systems that don’t have resources and need to save 25 KB of RAM), and support for filesystem-level encryption in ext4. The subsequent RCs add a few fixes, including one “so old that I almost thought if it’s been broken since 2011, and you only noticed now, maybe it could have waited.”

Linux 4.1 Kernel Benchmarks With An Intel Core i7 IVB System

Yesterday I ran some fresh tests of Intel Ivy Bridge on the latest Mesa Git code to see if the performance has changed much recently for the slightly-older generation of Intel HD Graphics. Today I’ve done some similar tests in kernel-space with the L…

Kernel prepatch 4.1-rc4

Linus has released the 4.1-rc4 kernel prepatch, saying: “So here it is, last-minute fix and all. The -rc4 patch is a bit bigger than the previous ones, but that seems to be mainly due to normal random timing – just the fluctuation of when submaintain…

Kernel Versions cleaned up!

I’ve just cleaned up the kernels table. We are measuring the statistics only from the official kernel versions from kernel.org. It makes no sense to show a kernel version like “3.16.23.11-ubuntu5-amd64-012345” or something like that. Instead only the single kernel versions are supported, for example: 2.1.45 or 4.0.3 or 3.11.23.
