Back in Linux 6.11 support for getrandom() in the vDSO was upstreamed for much better performance in providing speedy yet secure random number generation (RNG) needs. Since Linux 6.11 getrandom in the vDSO has expanded to more CPU architectures and now there's a notable user-space user ready to go: the GNU C Library "glibc" support was merged...

The Intel In-Memory Analytics Accelerator (IAA) found in various Xeon SKUs since Sapphire Rapids can be of big benefit to Linux servers/workstations with a Linux kernel patch series that has been in the works to provide Zswap IAA compress batching...

As covered last week Linux I/O expert Jens Axboe has been taking a fresh pursuit of uncached buffered I/O for Linux. This "RWF_UNCACHED" work was originally started back in 2019 while a renewed effort around it is showing ~65% faster read/write performance and so far has been extended to work across EXT4, Btrfs, and XFS file-systems...

One of the many changes to look forward to with the upcoming Linux 6.13 kernel cycle is the AMD P-State driver to be used by default with the new EPYC 9005 series processors. While AMD Ryzen CPUs for a while now have been defaulting to the modern AMD P-State driver that makes use of ACPI CPPC platform support for allowing better power efficiency, AMD EPYC CPUs have kept to using the generic ACPI CPUFreq frequency scaling driver. But now AMD engineers have deemed amd_pstate ready for use with EPYC 9005 "Turin" CPUs and will be the default choice moving forward. Here is more information and power/performance benchmarks for this shift while testing using the EPYC 9755 processors.

Microsoft last month announced the open-source Rust-written OpenHCL for running confidential Intel TDX and AMD SEV-SNP virtual machines. Today Microsoft is announcing another interesting open-source, Rust-based project in the virtualization space: Hyperlight. Microsoft's Hyperlight project is an embed-friendly, lightweight VMM for use within Linux and Windows applications...

While not as exciting as if it were Apple M3/M4 device support hitting the upstream mainline Linux kernel, but for those with some older Apple (pre-M1) devices around, support for a number of older SoCs and boards is set to arrive with the upcoming Linux 6.13 kernel...
