Bug-Catching "Smatch" Static Analysis On The Linux Kernel Under Threat Due To Funding Gap

For the past 15 years the Smatch static analysis tool has been routinely run for uncovering countless bugs within the Linux kernel. Dan Carpenter who authored Smatch and has been routinely analyzing the Linux kernel with it has authored more than 5,568 patches over the years to become one of the top bug fixers for the kernel. But his funding at Linaro has been cut and the project's future now in question...

Rust-Based Project Aims To Provide Modern Thumbnails For Audio/Video Files On GNOME

Since Showtime replaced Totem as the default video player of GNOME, the desktop has lacked thumbnail capabilities for audio and video files. But to address that defect, the Rust-based gst-thumbnailers project has been in development to leverage GStreamer and paired with Rust to provide safe thumbnail generation capabilities for audio and video content...

Live Update Orchestrator "LUO" Merged For Linux 6.19

Google engineers for the past number of months have been working on the Live Update Orchestrator as a new way of applying live Linux kernel updates. The Live Update Orchestrator "LUO" builds atop the Kexec Handover "KHO" functionality already within the kernel. Google has since been deplyoing LUO in their production environments for faster security updates to kernels, especially when involving VMs. LUO is now upstream in Linux 6.19...

Intel Arc B580 vs. AMD Radeon RX 9000 vs. NVIDIA RTX 50 Series For Llama.cpp Vulkan Performance

Recently there were Phoronix benchmarks looking at the Intel Battlemage GPU compute performance since last year when the Arc B580 graphics card launched as well as the OpenGL and Vulkan graphics performance for the B580 on Linux since launch. There was much progress on the open-source Intel Linux graphics drivers at large this year but especially for Battlemage. Following that a Phoronix Premium reader asked about seeing some fresh Llama.cpp AI benchmarks with its Vulkan back-end now for the Arc B580 compared to competing AMD and NVIDIA graphics cards. Here are those benchmarks as requested.

Early Benchmarks Of Linux 6.19 Git Raising Some Concerns

While just half-way through the Linux 6.19 merge window, over the weekend I began running some benchmarks of the current Linux 6.19 Git state compared to Linux 6.18 LTS stable. There are some minor performance improvements to note in a few of the tests on the first system I tested but also some regressions at this very early pre-RC1 state of the Linux 6.19 kernel...

Linux I3C Gains "HDR" Support For Faster Data Transfers

I2C in Linux 6.19 brought support for Rust-written I2C drivers. The newer I3C "Improved Inter-Integrated Circuit" interface changes have now been merged and the big feature there is HDR support. Not to be confused with the more common High Dynamic Range acronym usage for HDR, HDR in the I3C context is for the "High Data Rate" mode for facilitating faster data transfers...

Arm MPAM Driver Upstreamed To The Linux 6.19 Kernel

The ARM64 code changes were merged last week into the in-development Linux 6.19 kernel. The most notable of the ARM64 architecture changes this cycle is landing the Arm MPAM driver for Arm's Memory System Resource Partitioning and Monitoring...

Linux GPIB Drivers Declared Stable - 53 Years After HP Introduced The Bus

Merged to the mainline Linux kernel last year was GPIB drivers in the kernel's "staging" area. GPIB is the General Purpose Interface Bus launched by HP back in 1972 for lab equipment and more. After a year of cleaning up the code in the kernel's staging area, for Linux 6.19 the GPIB drivers have been promoted out of the staging area and into the Linux kernel proper. The Linux kernel now has stable driver support for this 8 Mbyte/s parallel bus that was introduced 53 years ago...

Linux 6.19 Introduces PCIe Link Encryption & Device Authentication, AMD SEV-TIO Enabling

One of the most exciting merges this weekend to the Linux 6.19 kernel is establishing the infrastructure for supporting PCI Express link encryption and device authentication. Multiple vendors are working on PCIe link encryption for their hardware while this initial pull begins laying the foundation of AMD SEV-TIO Trusted I/O support for the mainline kernel...
