[$] Modernizing swapping: introducing the swap table

The kernel’s swap subsystem is a complex and often unloved beast. It is
also a critical component in the memory-management subsystem and has a
significant impact on the performance of the system as a whole. At the
2025 Linux Storage, Filesystem, Memory-Management and BPF Summit, Kairui
Song outlined a plan to simplify and
optimize the kernel’s swap code. A first installment
of that work
, written with help from Chris Li, was merged for the 6.18
release. This article will catch up with the 6.18 work, setting the stage
for a future look at the changes that are yet to be merged.

Loongson 3B6000 Benchmarks: How China’s LoongArch CPU Compares To AMD Zen 5, Intel Arrow Lake & Raspberry Pi 5

Recently I finally got my hands on a LoongArch processor, the ISA developed by China’s Loongson Technology as an evolution from their earlier use of the MIPS64 ISA and inspired by RISC-V and other modern ISAs. The Loongson-3B6000 features 12 cores / 24 threads with dual channel DDR4 ECC memory support. Here is a look at how that latest-generation LoongArch desktop processor compares to the current generation AMD Zen 5 and Intel Arrow Lake desktop processors under Linux. Plus also tossing in the Raspberry Pi 5 (Raspberry Pi 500+) for an ARM reference point.

Experimental Linux Code For 1GB PUD-Level THPs Shows 34% Faster Memory Access Times

Early, experimental code for implementing 1GB PUD-level THPs in the Linux kernel are showing positive benchmark results but other upstream stakeholders were surprised by this patch series appearing and it looking like it could be a while until if/when the patches are mainlined for helping to reduce translaction lookaside buffer (TLB) pressure without resorting to Hugetlbfs…
