A new patch series posted today to the Linux kernel mailing list would block kernel modules/drivers from TUXEDO Computers from accessing GPL-only symbols in the kernel...

While it's difficult still finding Intel Xeon 6 "Granite Rapids" motherboards/servers widely available at Internet retailers/distributors, when it comes to the AMD EPYC 9005 "Turin" processors that launched just last month, there is better availability thanks in large part to leveraging the existing SP5 socket. For those wanting to assemble a single socket AMD EPYC 9005 series server, one of the readily available options in the retail channel is the Supermicro H13SSL-N motherboard.

The first public beta of Red Hat Enterprise Linux 10 (RHEL 10) was released on Wednesday with a wide variety of new/updated packages, new features, and other changes over RHEL 9...

Last month AMD Linux engineers posted patches for a 3D V-Cache Optimizer driver for Linux that allows the user to communicate their cache vs. frequency preference depending upon workload and for the 3D V-Cache processors where some CCDs have the larger cache but not all. That driver is now ready for appearing in the upcoming Linux 6.13 kernel...

A patch queued yesterday ino the Linux power management subsystem's "linux-next" branch ahead of the upcoming Linux 6.13 merge window will tune Intel Xeon Granite Rapids processors for better performance out-of-the-box...

Linux 6.10 introduced TPM bus encryption and integrity protection for enhancing the Trusted Platform Module support to protect against interposers from compromising them with TPM sniffing attacks. There is now a new option being added to opt-out of this protection due to a discovered performance bottleneck...

Zavedení emulace NUMA zvyšuje výkon u Raspberry Pi 4 a 5 průměrně až o 46 % ve vícevláknových úlohách. Použití emulace NUMA dokáže patrně lépe využít paměťový řadič v SoC Broadcom nebo paměť samotnou. Povíme si, jak emulaci NUMA vyzkoušet a otestovat.

V článcích o scikit-learn jsme se zabývali zpracováním a predikcí numerických dat. Ovšem v praxi je zapotřebí pracovat i s dokumenty psanými v přirozeném jazyce. I v takových případech najde scikit-learn své využití.

Last week Mesa 24.3 was finally branched and Mesa 24.3-rc1 subsequently issued for getting the release process kicked off for this quarterly 3D graphics driver feature release. Out today is Mesa 24.3-rc2 with an initial batch of fixes...

Apple last week released their latest iMac, Mac Mini, and MacBook Pro products powered by their fourth-generation M-series Apple Silicon. The new Mac Mini in particular is interesting for under $600 starting out with the all re-designed Mac Mini with 10-core M4 and now the base model having 16GB of memory. It will take some time before there is any reasonable Linux support on the M4 hardware with Asahi Linux, but for those curious about how the M4 Mac Mini with macOS compares to AMD Ryzen and Intel Core CPUs under Linux, here are some preliminary benchmarks.

Framework Computer has been promoting a RISC-V motherboard option for their Framework Laptop 13 to complement their existing Intel Core and AMD Ryzen motherboard options. This RISC-V motherboard is being developed in cooperation with DeepComputing. Early access pricing and more details on this quad-core StarFive JH7110 powered mainboard for the Framework 13 have now been announced...

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...

The NVIDIA MLX5 driver for NVIDIA Mellanox ConnectX-5 network adapters is preparing to introduce a new Data Direct Placement "DDP" feature with the upcoming Linux 6.13 kernel merge window...

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...

The AlmaLinux operating system project that was started from the fallout of the RHEL/CentOS development shift several years ago has once again courted AMD as a sponsorship of this community enterprise Linux operating system...
