The Performance Gains Brought By Linux 6.15+ & Mesa 25.2 For AMD Strix Halo

While the AMD Ryzen AI Max+ Strix Halo SoCs have a nice out-of-the-box experience with modern Linux distributions for the Radeon 8050S and Radeon 8060S graphics, if going for the recently-released Linux 6.15 kernel there are some performance gains to enjoy as well as if opting for the latest Mesa 25.2 development code for the latest RadeonSI OpenGL and RADV Vulkan driver support…

AMD’s Kernel Compute Driver “AMDKFD” Can Now Be Enabled On RISC-V

Following all of the Linux kernel graphics driver features merged last week for the Linux 6.16 kernel, sent out this morning were the initial batch of fixes to the Direct Rendering Manager (DRM) code. Besides fixes to these graphics / display / accelerator drivers, there is one new feature: the AMDKFD kernel compute driver can now be enabled on RISC-V systems…

[$] Zero-copy for FUSE

In a combined storage and filesystem session at the 2025 Linux Storage,
Filesystem, Memory Management, and BPF Summit (LSFMM+BPF), Keith Busch led
a discussion about zero-copy operations for the Filesystem
in Userspace
(FUSE) subsystem. The session was proposed
by his colleague, David Wei, who could not make it to the summit, so Busch
filled in, though he noted that “I do not really know FUSE so
well
“. The idea is to eliminate data copies in the data path to and
from the FUSE server in user space.

[$] Open source and the Cyber Resilience Act

The European Union’s

Cyber Resilience Act
(CRA) has caused a stir in the
software-development world. Thanks to advocacy by the Eclipse Foundation, Open
Source Initiative, Linux Foundation, Mozilla, and others, open-source software
projects generally have minimal requirements under the CRA
— but nothing to do with law is ever quite
so simple. Marta Rybczyńska spoke at Linaro Connect 2025 about the impact of the
CRA on the open-source ecosystem, with an emphasis on the importance of
understanding a project’s role under the CRA. She later participated in a panel
discussion with Joakim Bech, Kate Stewart, and Mike Bursell about how the CRA
would impact embedded open-source development.

Linux 6.15 & Early Linux 6.16 Delivering Some Additional Gains For AMD Strix Halo

As some extra benchmarks to put out today for the Phoronix.com 21st birthday, there is some additional data points to share on AMD Strix Halo when using Linux 6.15 stable and the early development state of Linux 6.16 Git ahead of its v6.16-rc1 tagging this weekend. The Linux kernel performance is moving in the right direction at least with this round of testing using the HP ZBook Ultra G1a with Ryzen AI Max+ PRO SoC…
