A few weeks back we reviewed the redesigned System76 Thelio Mira with a brand new chassis design and powered by the AMD Ryzen 9000 series. This was an interesting Linux-powered desktop manufactured in Colorado while for those needing a bit more performance, since then the redesigned Thelio Major launched. The new System76 Thelio Major provides an updated Thelio case design like Mira while comes packed with the AMD Ryzen Threadripper 9000 series and AMD Radeon AI PRO R9700 graphics for delivering a very powerful, all-AMD and open-source high-end Linux workstation.

Introduced in Linux 7.0 was FSERROR as generic I/O error reporting infrastructure. Linux to that point had no standardized mechanism for reporting metadata corruption or file I/O errors to user-space with each file-system doing its own thing. The Flash-Friendly File-System (F2FS) is now the latest Linux file-system preparing for FSERROR usage...

In late 2023 I reviewed the HP Z6 G5 A workstation that at the time was built around the AMD Ryzen Threadripper PRO 7000 series and NVIDIA RTX Ada Generation graphics. More recently, HP has revised the Z6 G5 A workstation for the latest Threadripper PRO 9000 series and NVIDIA RTX PRO Blackwell graphics. HP sent over the upgraded Z6 G5 A workstation that I've been benchmarking the past few weeks. This workstation remains Linux-friendly down to convenient LVFS/Fwupd support and delivers stellar performance with the Zen 5 Threadripper and NVIDIA Blackwell combination.

For those trusting enough in local LLM pipelines to do the right thing, there is even integration now for AMD GAIA to interface with your Gmail account...

With Intel's recently-launched Bartlett Lake P-core-only processors intended for the embedded market, there is a rather surprising oversight under Linux: the Intel P-State driver reporting a 7.0+ GHz clock speed. While many would yearn for a 7GHz CPU, the Core 9 273PE where this issue was discovered in reality can only boost up to 5.7GHz for its maximum turbo frequency...

One week after the Copy Fail vulnerability, a new Linux local privilege escalation bug has been made public. This time around there are no patches or CVEs yet for this "Dirty Frag" vulnerability as the embargo was broken early and thus the security researcher went ahead and published earlier than anticipated...

Following Linux 7.1 beginning to phase out i486 CPU support and in turn drivers like those for the old AMD Elan SoCs now being removed, for Linux 7.2 the processor support removal is going further to now include some i586 and i686 class processors...

The Realtek RTL8159 has been appearing in some 10G-rated USB network adapters at online retailers, some for less than $100 USD. But currently the RTL8159 is only supported by Realtek's out-of-tree Linux kernel driver, but fortunately there will be mainline support coming with the Linux 7.2 kernel this summer...

While there is the AMD Instinct MI400 series coming this year, today AMD announced an interesting and arguably overdue offering for the Instinct MI350 series: the MI350P. The AMD Instinct MI350P is a PCIe add-in-card to add Instinct MI350 compute capabilities to existing PCIe 5.0 air-cooled servers as an alternative to the Open Accelerator Module (OAM) currently used by the Instinct MI350 series.

Merged for the current Linux 7.1 cycle was beginning to phase out the Intel 486 processor support from the mainline kernel moving forward. That initial step with Linux 7.1 was dropping the various Kconfig options to allow compiling Linux kernel builds for targeting various i486 platforms. As part of that, the AMD Elan SoC configuration patches were dropped. The next step is proceeding on the AMD Elan side with beginning to remove the actual driver code...

KDE developer Xaver Hugl has whipped up another nice improvement for the upcoming Plasma 6.7 desktop release. Due to QtWidgets still relying on CPU-based rendering and finding the performance subpar with Wayland shared memory "wl_shm" usage, Xaver has leveraged UDMABUF for avoiding excess buffer copies to provide a much more fluid experience when dealing with CPU-based rendering / shared memory usage on KDE under Wayland...

When it comes to compiling C/C++ code to WebAssembly (WASM), LLVM/Clang and other LLVM-based tooling has dominated the space.

Sent out today was a batch of "new stuff" for the AMDGPU graphics and AMDKFD compute kernel drivers that are ready for DRM-Next to queue until the Linux 7.2 merge window happens in June. Most notable is the introduction of the AMDGPU DC power module to better align with the Radeon power management behavior under Microsoft Windows...

When having the HP Z6 G5 A workstation in the lab for benchmarking, one of the curiosity-driven tests was seeing how well the latest open-source and upstream Nouveau driver stack is competing against the latest official NVIDIA R595 driver for workstations. The official NVIDIA Linux driver stack remains the best positioned software solution for RTX (PRO) hardware but Nouveau continues evolving while awaiting the Nova kernel driver to reach the limelight.

Exciting yesterday in the land of Intel's open-source Vulkan driver "ANV" for Linux systems was introducing experimental support for descriptor heaps with the VK_EXT_descriptor_heap extension.
