AMD EPYC Achieves 5G/6G RAN Performance Leadership With New OCUDU Project

Announced this week at Mobile World Congress (MWC) by the Linux Foundation was the establishing of the OCUDU Ecosystem Foundation for advancing open-source AI-RAN (Radio Access Network) innovations. OCUDU is building a reference platform and innovations around 5G and early 6G network solutions. With OCUDU being benchmark-friendly, I have been putting the early code through some performance tests on current AMD EPYC and Intel Xeon server platforms.

The OCUDU software is an evolution of the srsRAN Project by Software Radio Systems (SRS)

Linux Preps IBPB-On-Entry Feature For AMD SEV-SNP Guest VMs

Heading toward the Linux 7.0 kernel and marked for back-porting to current stable Linux kernel versions is employing a new SEV-SNP security feature found on AMD Zen 5 processors for enhancing security of guest virtual machines.

A patch is on its way to the mainline Linux kernel to allow the IBPB-on-Entry feature for AMD SEV-SNP guest VMs. The IBPB-on-Entry feature is supported by AMD EPYC Zen 5 processors. Only a few lines of code are needed to enabl this feature for

AMD Engineer Leverages AI To Help Make A Pure-Python AMD GPU User-Space Driver

AMD's VP of AI Software, Anush Elangovan, has used Claude Code to help craft a pure-Python AMD GPU user-space driver. This Python user-space driver is currently being created to help exercise other ROCm code and for debugging in passing through the ROCm/HIP user-space stack.

Anush was inspired by Tinygrad's user-space AMD GPU driver implementation and with Claude AI has created a user-space driver for stress testing of SDMA and compute/communications overlap debug. Anush posted on

Old ATI R300 Open-Source Driver Sees Another New Fix In 2026

The Radeon R300 series turns 24 years old this year and thanks to the open-source ATI R300 Gallium3D driver that began via reverse engineering, it's still continuing to see the occasional random fixes from the open-source community.

Independent open-source developer Pavel Ondračkar has managed to fix occlusion query support in the R300 driver for benefiting R300 through R500 class ATI GPUs. Pavel explained in a recent merge request that

Ubuntu Still Figuring Out A Plan For Dealing With California's Digital Age Assurance Act

The talk this week among open-source projects from Linux distributions to app stores like Flathub is how to deal with California's latest insanity: the Digital Age Assurance Act. California's AB 1043 state law is mandating that operating systems -- Linux included -- collect age information during account setup and exposing that age to eligible apps beginning on 1 January 2027. That leaves much uncertainty for Linux distributions and other repositories/stores and more. Canonical issued a statement today to clarify that

Using KMSCON As The Default VT Console Delayed To Fedora 45

For the past few months have been an ambitious proposal to replace FBCON with the user-space KMSCON as the default VT console starting on Fedora 44. Unfortunately, this and a few other features have now been delayed to the Fedora 45 release six months later.

Fedora 44 will no longer be aiming to switch over to KMSCON as the default VT console. The change proposal to replace the kernel console with this user-space solution has been diverted to being a Fedora 45 feature. Hopefully by October everything

AMD DPTCi Driver Posted For Linux To Better Enhance Ryzen Gaming Handhelds

A request for comments (RFC) patch series was posted today to the Linux kernel mailing list to introduce the AMD Dynamic Power and Thermal Configuration Interface "DPTCi" driver. With this driver it would provide better upstream Linux kernel support for tuning the power / performance / thermals of modern Ryzen-powered gaming handheld devices. Though don't get too excited right away as the driver was assembled in part by AI that is already causing a bit of a ruckus on the LKML due to lack of disclosure.

Antheas Kapenekakis is

Google Chrome Moving To A Two-Week Release Cycle

Google announced today that beginning later this year they are moving the Chrome web browser from its four week release cycle down to a two week release cadence.

Starting in September, Google will move to a two-week release cycle. Google is doing this on the basis that "the web platform is constantly advancing" and they want to move to shipping performance improvements, fixes, and new capabilities even quicker to developers and end users.

The hope is with these smaller two-week releases there will be less disruption and simplifying
