Linux Hardware Reviews & Performance Benchmarks, Open-Source News

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.

With Linux 6.19 due for release later today it then opens up the next kernel merge window. It could be Linux 6.20 but more than likely the next kernel version will be called Linux 7.0 with Linus Torvalds' past tradition of bumping the major version number after X.19. Whatever it ends up being called, here is a look at various "-next" changes that have been queuing up ahead of the merge window.

Back in 2021 on Phoronix was first to report on Intel preparing Linux patches for a "Software Defined Silicon" feature for activating extra licensed hardware features.
