Another x86 Advisory From Some Entity Other Than Intel Or AMD
Another x86 Advisory From Some Entity Other Than Intel Or AMD
29 August 12:24 PM EDT - Hardware - WBINVD Usage - 6 Comments

Last October I highlighted an interesting post on the Linux kernel mailing list around an x86 corporate entity other than Intel or AMD that left mysterious intrigue. The developer that detailed those x86 opcode/CPUID/MSR allocations back in July then detailed 16-tile and 32-tile AMX implementations again for something outside the current scope of Intel/AMD processors. Today another message is being relayed from that "corporate entity other than Intel/AMD."

HP Z4 G6i: A Linux-Friendly Workstation Powered By The Intel Xeon 600 Series
HP Z4 G6i: A Linux-Friendly Workstation Powered By The Intel Xeon 600 Series
28 August 10:25 AM EDT - Computers - 1 Comment

The past month I have been testing out the HP Z4 G6i workstation across many different workloads and grueling tasks. This HP workstation powered by the Intel Xeon 600 series "Granite Rapids WS" and NVIDIA RTX graphics offers a lot of compute power, but with the top-end configuration retailing for over $41k USD is quite pricey in today's environment. Windows 11 Pro is the default operating system of the HP Z4 Gi but Ubuntu LTS releases are supported and it's "Linux-ready" at large.

28 August 09:02 AM EDT - Linux Kernel - Linux Kernel CVEs - 32 Comments

With the proliferation of AI/LLM models analyzing the Linux kernel's vast codebase, there has been a surge in the number of CVEs per kernel release. After typically being around 500 CVEs fixed per release, we are now approaching 2,000 CVEs fixed per release and perhaps will break that threshold for Linux 7.3.

Google Summer of Code 2026 featured a project working on GPU reset recovery for GNOME's Mutter compositor. GSoC has now wrapped up and the project overall was largely successful although some outstanding work remains. In this last week the merge request has been opened to conduct code review on this GPU reset recovery implementation for GNOME.

Linux 7.3 Will Begin Checking USB-C Cables For Alt-Mode Support
Linux 7.3 Will Begin Checking USB-C Cables For Alt-Mode Support
28 August 06:15 AM EDT - Hardware - USB-C cable checking - 12 Comments

The USB and Thunderbolt changes have been merged for Linux 7.3. Two changes stand out for me in the USB subsystem code with Linux 7.3. First, the kernel arguably being long overdue for checking USB-C cables capabilities whether they support alt-modes. Second, a new low-latency USB4STREAM option for lower latency data transfers between USB4-connected systems.

Old IBM Driver Joins Insecure SGI Drivers In Being Removed For Linux 7.3
Old IBM Driver Joins Insecure SGI Drivers In Being Removed For Linux 7.3
28 August 05:58 AM EDT - Linux Kernel - char/misc - Add A Comment

The char/misc changes were merged this week for the Linux 7.3 cycle. While there is a lot of IIO driver churn as usual and updates to the likes of the Google Binder drivers, there continues to be the 2026 trend of removing old hardware drivers that are rarely updated these days and likely have no active users left on the mainline Linux kernel. This trend is further pushed along by the surplus of AI/LLM-generated bug reports and patches these days causing additional maintenance burden for these obsolete drivers.

Intel Linux Driver Orphaned For Limiting RF Exposure To Humans
27 August 05:13 PM EDT - Intel - Intel Specific Absorption Rate Driver - 6 Comments

Over the past year and a half a number of open-source drivers in the Linux kernel have been orphaned as a result of departures from the company. The impact has ranged from the Intel CPU "coretemp" temperature driver being orphaned without a maintainer to other lesser known Intel drivers. Another lesser known Intel driver is now being orphaned with no longer having a maintainer at the company: the Intel Specific Absorption Rate Driver.

AMD Preparing To Enable HDMI 2.1 FRL Support By Default For Linux
27 August 03:45 PM EDT - Radeon - HDMI FRL Default - 2 Comments

It was back in May that the surprising event happened of AMD posting HDMI 2.1 FRL patches for their open-source AMDGPU Linux driver as part of their broader HDMI 2.1 bring-up. For years the open-source HDMI 2.1 support in AMDGPU was blocked by the HDMI Forum but whether it was due to Valve or some other event, the code was finally unblocked. While it's been part of the kernel since Linux 7.2, it's been disabled by default -- except that is now changing.

AMD Jumps From ROCm 7.14 To ROCm 10.0 With ROCm.AI
27 August 11:26 AM EDT - AMD - AMD ROCm 10.0 - 33 Comments

Back in July ROCm 7.14 was announced as their new production release built atop TheRock build system and introducing Ryzen AI 400 series support. The versioning choice was a bit odd since ROCm 7.2 was the stable release at the time while ROCm 7.9+ turned into "tech preview" releases. With ROCm 7.14, it was declared stable. In clearing up that versioning mess, they have done a major version bump... to ROCm 10.0.

Btrfs, EXT4, F2FS & XFS On Linux 7.2 vs. Linux 7.3 Performance
27 August 11:13 AM EDT - Software - 66 Comments

Earlier this week I showed off some of the very nice Btrfs performance gains on Linux 7.3. For those wondering what kernel optimizations may have carried over to other file-systems or other file-system specific enhancements, here are Linux 7.2 vs. 7.3 Git performance benchmarks across Btrfs, EXT4, F2FS, and XFS on the same system.

Linux 7.3 Adds RWF_DONTCACHE Support For Block Devices
27 August 10:15 AM EDT - Linux Storage - RWF_DONTCACHE On Block Devices - Add A Comment

With the never-ending quest for greater I/O performance in the HPC space and the demands all the more relentless in the AI era, the Linux kernel block subsystem activity continues to be as vibrant as ever along with the ongoing innovations in the IO_uring space.

Intel ANV Driver Improves Vulkan Video H.265 Decoding
27 August 06:32 AM EDT - Intel - H.265 Vulkan Video - 5 Comments

Merged back in 2023 was Intel ANV Vulkan Video support for H.265 decoding. But it's been slightly out of compliant with the Vulkan spec, which is now fixed with the newest code for Mesa 26.3 by engaging the HuC firmware.

LLVM Improves Zen 1 / Zen 2 Support To Deal With "Notoriously Bad" PDEP/PEXT
27 August 06:05 AM EDT - LLVM - LLVM Clang - 7 Comments

The LLVM/Clang compiler toolchain merged overnight better support for the nearly decade-old AMD Zen 1 processors and also helps with Zen+ and Zen 2 processors too. This latest work thanks to the open-source community is for providing more informed instruction scheduling around PDEP and PEXT that end up being quite costly for these original Zen processors.

AMD Proposes New LLVM iTHP Option For Squeezing More Performance
26 August 10:49 AM EDT - LLVM - -fenable-readonly-thp - 2 Comments

AMD's compiler team is proposing a new LLVM Clang compiler option, -fenable-readonly-thp for implementing instruction Transparent Huge Pages "iTHP" at compile and link-time. With -fenable-readonly-thp, they are finding more performance out of SPEC CPU, Geekbench, and other workloads from the arranging of 2MB segment alignment at link time and allowing the executable text range can be promoted to huge pages.

Fedora + Tuned-PPD Performance Regression Should Be Fixed With New Linux Kernel
26 August 10:13 AM EDT - Fedora - Framework Laptop 13 Pro - 4 Comments

Earlier this month when benchmarking six Linux distributions on the new Framework Laptop 13 Pro powered by Intel Core Ultra Series 3 "Panther Lake", the performance was strangely slow on Fedora Workstation 44. When digging further into it, the performance loss was with Fedora 44 using Tuned-PPD by default where as other Linux distributions default to Power Profiles Daemon. Ultimately, after Red Hat engineers got involved, was found to be a bug within the Intel P-State kernel driver exhibited by Tuned-PPD. The latest Linux kernel already has a fix in place and will be back-ported to Fedora 44.

AMD Introduces New "GFX1250-STRICT" GPU Target In LLVM
26 August 06:22 AM EDT - AMD - AMD gfx1250-strict - Add A Comment

The AMD GFX1250 IP is what's used by the new Instinct MI450 series accelerators. That's been around within the Linux kernel, AMDGPU LLVM compiler back-end, and related codebases the past year. Interestingly merged yesterday is a new "gfx1250-strict" target.
