While the Bcachefs feature changes for Linux 6.13 were already submitted even before the Linux 6.12 stable kernel was released, merging these changes are supposedly on hold due to the kernel's Code of Conduct (CoC) board...
Andrew Morton on Monday submitted all the memory management "MM" related patches for the Linux 6.13 merge window. As usual there's a lot of interesting performance optimizations and other low-level refinements...

As I wrote about last week within the Supermicro H13SSL-N EPYC Turin motherboard review, one of the factors leading me to purchasing that EPYC 9005 series motherboard was that this board offered support for full 12 channel DDR5-6000 memory performance compared to some of the other lower-cost Socket SP5 motherboards offering just 8 memory channels. For those wanting to quantify the performance difference between eight and twelve memory channels with AMD EPYC 9005 "Turin" processors, here are some benchmarks for showing the workloads that can really benefit from all 12 memory channels and other workloads where eight memory channels can be largely sufficient if looking to minimize costs.
Following the initial Raspberry Pi 5 upstream support in Linux 6.12 providing basic support, an exciting Raspberry Pi addition with the in-development Linux 6.13 kernel is introducing a Raspberry Pi Camera Front-End "CFE" driver...
The crypto subsystem updates were merged yesterday for the in-development Linux 6.13 kernel. Among other crypto improvements are new optimizations for some algorithms when running on Intel and AMD x86_64 processors...
Merged last year for Linux 6.6 was multi-grain(ed) timestamps to address the current coarse-grained timestamps when updating creation time and modification time that a lot of I/O activity can happen in the once-per-jiffy timestamp. Just a few weeks in the Linux 6.6 kernel, multi-grain timestamps were removed due to bugs. The multigrain code went back to be reworked and now just over one year later the code has been re-merged into the mainline Linux kernel...
While most users frown upon the increasing number of CPU security mitigations in part due to the additional overhead commonly introduced, a new Linux kernel patch by a Google engineer would allow users/developers to opt-in to forcing CPU bugs and their mitigations even if the system in use isn't known to be vulnerable...

A few weeks back I wrote about Intel engineers preparing SNC6 support with Linux for six nodes per L3 cache. That was the first time hearing of SNC6 with SNC 1/2/3/4 sub-NUMA clustering modes being more common. That support is now ready for merging with the Linux 6.13 kernel cycle...
Arch Linux package sources with its PKGBUILD files and similar have lacked carrying a clear license. Arch Linux developers have been working to come together to allow all Arch Linux package sources to be licensed under a BSD zero-clause "BSD0" license...
The GNU Linux-libre 6.12-gnu kernel is now available as the downstream of the newly-christened Linux 6.12 kernel that aims to remove code depending upon non-free microcode/firmware or relying on other elements of code deemed non-free software even with much of today's hardware requiring proprietary firmware for operation...
As of today the first handful of commits have landed in LLVM Git ahead of next year's LLVM 20.0 for beginning to enable the AMDGPU compiler back-end for "GFX950", the next iteration of the CDNA family for Instinct accelerators...
The Linux kernel Workqueue (WQ) is used for handling asynchronous process execution. For the past many years there has been an upper limit on the number of workqueue execution contexts per CPU at 512, but with Linux 6.13 that is being quadrupled to a limit of 2048...
Over the past year we have seen Canonical engineers focus more on optimizing the performance potential of Ubuntu Linux. With Ubuntu 25.04 they are now using the -O3 compiler optimization level by default and there has been other efforts like better performance tooling on Ubuntu and frame pointers by default. Another area they have been exploring is making use of Profile Guided Optimizations (PGO) for faster performance in certain scenarios...
At the beginning of November I wrote about AMD Linux engineers posting Linux patches enabling a new "ERAPS" feature for Zen 5. ERAPS wasn't talked about by AMD at the Zen 5 launches of the Ryzen 9000 / Ryzen AI 300 series or with the more recent EPYC 9005 "Turin" launch but when enabled, the Enhanced Return Address Prediction Security feature can help deliver some additional gains on new AMD Zen 5 systems by allowing some existing software security mitigations to be avoided. Here are some preliminary comparison benchmarks showing the benefit in affected workloads for using ERAPS on Linux with AMD Zen 5.
