Linux Kernel Podcast

Jon Masters summarizes the arrival of the Linux 6.3 kernel release, which includes additional support for the Rust programming language, a new red-black tree data structure for BPF programs, and the removal of a large number of legacy Arm systems.

Jon Masters summarizes the closure of the Linux 6.3 "merge window" (period of time during which disruptive changes are allowed to the kernel) and the release of Linux 6.3-rc1. Meanwhile, ongoing development includes the deprecation of several legacy architectures, an Apple Silicon graphics driver written in Rust, and much more.

Jon Masters summarizes the tail end of the Linux 6.2 kernel development cycle as developers prepare for the upcoming 6.3 "merge window" in the week ahead. Meanwhile, ongoing development across the stack focuses heavily on Confidential Compute technologies from the various processor architecture vendors.

The Linux "Kernel Podcast" returns from a long hiatus for a new "season 2". Our host Jon Masters introduces the new season, and summarizes recent happenings during Linux 6.2 development.

Linus Torvalds announces Linux 4.11-rc3, this week's exciting installment of "5-level paging weekly", the 2038 doomsday compliance "statx" systemcall, and heterogenous memory management. Also a summary of all ongoing active kernel development toward 4.12 onwards

Linus Torvalds announces Linux 4.11-rc2 (including pre-enablement for Intel 5-level paging), VMA based swap readahead, and ongoing development ahead of the next cycle.

Linus Torvalds announces Linux 4.11-rc1, rants about folks not correctly leveraging linux-next, the remainder of this cycle's merge window pulls, and announcements concerning end of life for some features.

The merge window for kernel 4.11 is open and patches are flying into Linus's inbox, fixing NUMA node determination at runtime, Virtual Machine Aware Caches, Advisory Memory Allocations, and a non-fixed TASK_SIZE to bring excitement to your life.

In this week's edition: Linus Torvalds announces Linux 4.10, Alan Tull updates his FPGA manager framework, and Intel's latest 5-level paging patch series is posted for review. We will have this, and a summary of ongoing development in the first of the newly revived Linux Kernel Podcast.
