In addition to the USB updates and big staging flush merged yesterday for the Linux 6.13 kernel merge window, the "char/misc" pull was also honored for that catch-all of various kernel changes. With the char/misc pull there are some notable additions for those wanting to write kernel drivers within the Rust programming language.

Clang AutoFDO + Propeller Optimization Support Merged For Linux 6.13
30 November 2024 - AutoFDO + Propeller

Last night when writing about the Clang AutoFDO and Propeller optimization patches sent in for Linux 6.13 I had wondered whether Linus Torvalds would go through with the pull request given some of his past commentary around aggressive compiler optimizations... But to much delight, this evening Linus Torvalds has merged the Kbuild pull request that introduces Clang-based AutoFDO and Propeller compiler optimization support for allowing greater kernel performance out of tailored (profiled) workloads.

NVIDIA's New Linux Patches For GPU Direct RDMA For Device-Private Pages
1 December 2024 - P2P DMA For GPU-Centric Apps

NVIDIA engineer Yonatan Maman posted a set of "request for comments" patches this Sunday to implement GPU Direct RDMA "P2P DMA" for device private pages. This is the latest in the effort by multiple vendors to allow more efficient data sharing between GPUs/accelerators and other devices like network adapters.

Linus Torvalds Comes Out Against "Completely Broken" x86_64 Feature Levels
5 December 2024 - No Feature Levels In The Kernel

With the new Linux kernel patches posted yesterday for cleaning up x86 32-bit kernels on x86_64 CPUs as part of that patch series was introducing new Kconfig build options around the x86_64 micro-architecture feature levels. It turns out though that Torvalds is completely against how the x86_64 feature levels are handled by the compiler toolchain folks and doesn't want to see it invading the kernel.

It's been a while since there have been any new advancements or performance optimizations to talk about for Multi-Gen LRU (MGLRU) that was upstreamed to the Linux kernel two years ago as a very exciting kernel innovation. But that's changing now with some fresh performance optimizations being worked on for the MGLRU code.
