Cloud Hypervisor 42.0 is out as the newest update of this open-source, Rust-based hypervisor that began as an Intel software project but is now developed by a number of different organizations from Arm to Microsoft...

For the upcoming Linux 6.13 cycle there is Xe2 Ultra Joiner and GPU temperature monitoring support along with initial Xe3 graphics support for integrated form with Panther Lake among the Intel graphics driver changes expected so far. Another batch of the Xe kernel graphics driver changes were submitted today for modern Intel graphics with this upcoming Linux 6.13 cycle...

When a number of Russian Linux developers were removed from their MAINTAINERS file in the Linux kernel, it was described as due to "compliance requirements" but vague in what those requirements entailed. Linus Torvalds then commented on the Russian Linux maintainers being de-listed and made it clear that they were done due to government compliance requirements / legal issues around Russia. Now today some additional light has been shed on those new Linux kernel "compliance requirements"...

Earlier this month Intel announced the Core Ultra 200S "Arrow Lake" processors and today they go on sale. In turn, the review embargo also lifts for these new desktop processors. Up first today on Phoronix is the Intel Core Ultra 9 285K Linux performance review for this flagship 24-core desktop processor.

For the recently launched AMD EPYC 9005 series "Turin" processors there is good support out-of-the-box running on the likes of Linux 6.8 as found with Ubuntu 24.04 LTS. The one exception is if wanting to engage CPU power monitoring you need a RAPL/PowerCap patch that was just upstreamed in v6.12. But what about using a newer kernel for greater performance in light of all the upstream optimizations to the kernel in general? Here are some Linux 6.8 vs. 6.11 vs. 6.12 kernel benchmarks on a dual AMD EPYC 9755 server...

Intel today released the Intel Media Driver 2024Q3 release to provide updated Video Acceleration API (VA-API) support for Linux systems along with an updated oneVPL GPU Runtime...

Going back to 2016 we've known of NVIDIA beginning to use RISC-V to replace their Falcon micro-controller and other micro-controllers within their graphics processors to using this common open-source ISA. That use has continued to grow and an unofficial estimate now puts it at around one billion RISC-V cores shipping in 2024 NVIDIA chips...

Following the launch of the Raspberry Pi AI Kit back during the summer with up to 13 TOPS performance for AI inference, the Raspberry Pi AI HAT+ was announced today with up to 26 TOPS capabilities...

Following the ASUS AIPT patch posting this weekend from an Intel Linux engineer that was analyzing my previously-published Lunar Lake results showing rather poor performance on the ASUS Zenbook S 14, the performance has been looking much better. On Monday I posted updated Intel Xe2 graphics results showing strong uplift now that the ASUS Lunar Lake laptop was operating in its standard mode rather than whisper mode. In today's article is data from more than 400 CPU/system benchmarks to see how the Core Ultra 7 256V performance has improved with this new Linux kernel patch and compared to the prior AMD Ryzen and Intel Core laptop comparison data.

Following yesterday's news first featured on Phoronix of several Linux driver maintainers being de-listed from their maintainer positions within the mainline Linux kernel over their connections to Russia, Linus Torvalds has today commented on the matter...

More than a decade ago the DTrace tracing framework from Sun Microsystems was one of the long sought features from Solaris desired by Linux developers. Oracle ended up porting DTrace to Linux over the years but without too much fanfare outside of Oracle Linux especially since the advent of (e)BPF on Linux and other tracing/debugging open-source advancements. With the recent DTrace 2.0, it's now built atop the BPF engine and other upstream kernel tracing features on Linux. Gentoo Linux today announced their support for DTrace 2.0...

Google engineer Eric Biggers has worked on some very nice performance optimizations for the crypto code within the Linux kernel such as faster AES-GCM for Intel and AMD CPUs, much faster AES-XTS disk/file encryption with modern CPUs, and many other optimizations over the years. His latest work is on enhancing the CRC32C crypto performance for x86/x86_64 processors...

Intel engineers this morning sent out their newest pull request of "drm-intel-gt-next" material to queue in DRM-Next ahead of the upcoming Linux 6.13 merge window. There is a new feature enabled on newer Intel graphics hardware as well as some improvements for very old Intel integrated graphics...

It was just earlier this week that AMD posted Linux patches to switch EPYC over to using the AMD P-State driver rather than the long-used generic ACPI CPUFreq driver. This should lead to better power efficiency out-of-the-box and is a change being made just for EPYC 9005 "Turin" CPUs and future server processors. Already it's looking like this change will be introduced for the upcoming Linux 6.13 merge window...

It was just one and a half years ago that Cloudflare began rolling out OpenBMC on their massive array of servers to replace traditional proprietary Baseboard Management Controller (BMC) firmware stacks. Since the end of last year they've been talking up their successes using OpenBMC and now as we approach two years of their OpenBMC use within production, they continue singing the praise of this open-source, Linux-based BMC software stack...

Intel has upstreamed the firmware for their "BlazarU" core to linux-firmware.git for improving the out-of-the-box wireless experience with newer Intel WiFi adapters...

The Free Software Foundation announced on Tuesday they have begun work on "freedom in machine learning applications". Or in particular, a to-be-issued "statement" on free machine learning applications for software and the associated scripts and training data...

Rustls was initially talked up as a modern TLS library written in the Rust programming language for its memory safety guarantees. But now besides the talked up advantages due to being written in Rust, it has reached the point of reportedly being faster than both OpenSSL and BoringSSL...

Quietly merged into this week's Linux 6.12-rc4 kernel was a patch that removes a number of kernel maintainers from being noted in the official MAINTAINERS file that recognizes all of the driver and subsystem maintainers...

AlmaLinux Kitten 10 has been introduced today as what will be the next iteration of this community-based, RHEL/CentOS-derived enterprise-grade Linux distribution. AlmaLinux Kitten 10 is tracking the CentOS Stream 10 sources for what will eventually become the base of Red Hat Enterprise Linux 10...
