AMD Secure Encrypted Virtualization with Secure Nested Paging (SEV-SNP) provides memory encryption and integrity protections that can be especially useful in modern cloud computing. Typically a 2~10% performance overhead is reported when engaging AMD SEV-SNP for these hardware-backed security protections. In this article is an extensive look at the current AMD SEV-SNP performance impact for confidential computing on EPYC 9005 "Turin" servers. The current Ubuntu 24.04 LTS was tested as well as an Ubuntu 26.04 development snapshot in evaluating the latest optimizations and what is on the horizon this year for AMD EPYC Linux server performance.

As some long overdue housekeeping, the Linux 7.0 kernel has removed an Error Detection And Correction "EDAC" driver for the Intel 440BX and 440GX chipset. The driver is being removed not only because that chipset was just used by old Celerons and Pentium II / Pentium III CPUs but that it's been in the kernel all this time while being known to be broken for 19+ years...

The slab memory allocator feature updates have been merged for the Linux 7.0 kernel. Most notable this cycle is expanded use of the recently-introduced Sheaves functionality...

Merged for the Linux 6.19 kernel was initial Nova Lake S audio support. Now merged this week for the Linux 7.0 kernel is enabling sound support for additional Nova Lake platforms...

The XFS file-system has some interesting new feature work and performance tuning with the Linux 7.0 kernel that will be used by the likes of Fedora 44 and Ubuntu 26.04 LTS this spring...

Not in time for the current Linux 7.0 cycle but posted for another round of review is Intel's latest work around Cache Aware Scheduling for enhancing the performance of modern CPUs with multiple cache domains. This is the first set of updates to Cache Aware Scheduling for the new year and succeed the v2 patches from early December. This work not only benefits modern Intel CPUs but our testing has shown can also provide some very nice gains too for AMD EPYC processors...

Sent out and already merged today for the Linux 7.0 kernel are the EXT4 file-system updates...

Merged today to Mesa 26.1-devel is unifying of the AMD video decode implementation between the RadeonSI Gallium3D and RADV Vulkan drivers...

In addition to all of the exciting Intel and AMD x86_64 enhancements that have been landing this week so far for the Linux 7.0 kernel, the aging SPARC, Alpha, and Motorola 680x0 "m68k" CPU ports have also seen some patches for this new kernel...

Earlier this month I posted benchmarks of the Loongson 3B6000 for this 12-core / 24-thread LoongArch Chinese CPU with DDR4 ECC memory. Those initial benchmarks were done with Debian LoongArch64 while since then I've shifted over to using Arch Linux on LoongArch.

Canonical released Ubuntu 24.04.4 LTS today as the newest point release to the Noble Numbat...

The Linux 7.0 networking pull request showcases two extremes and the diversity and robustness of the open-source kernel ecosystem. Linux 7.0 is laying the groundwork for WiFi 8 Ultra-High Reliability (UHR) support while this kernel version is also bidding farewell to the last Ethernet driver for use over parallel printer ports...

The Linux kernel's workqueue for async task handling within a dedicated kernel thread is seeing some useful improvements with Linux 7.0...
