AMD Ryzen AI 7 PRO 360 Linux Performance With The Lenovo ThinkPad T14s Gen 6

Phoronix - Thu, 04/10/2025 - 22:20
For those that are curious about the Linux support and performance of the AMD Ryzen AI 7 PRO 360 laptop processor, I've recently been testing it out within a Lenovo ThinkPad T14s Gen 6 (AMD) laptop. Up today are benchmarks of the Ryzen AI 7 PRO 360 within the ThinkPad T14s Gen 6 up against an assortment of other recent Intel and AMD laptops all while running the near-final state of Ubuntu 25.04.

Graphics/Display Driver Changes Begin Queuing For Linux 6.16 This Summer

Phoronix - Thu, 04/10/2025 - 21:48
While the Linux 6.15 merge window only ended last weekend, new feature material is beginning to queue for DRM-Next ahead of the Linux 6.16 kernel cycle kicking off in late May or early June. A few notable patches so far have been submitted by way of DRM-Misc-Next...

Linux Tightening Up AMD Zen 5 CPU Microcode Check

Phoronix - Thu, 04/10/2025 - 20:34
Google engineers earlier this year detailed an AMD CPU microcode signature verification vulnerability. For local users with administration/root privileges, it could lead to loading malicious CPU microcode patches on the system. Initially AMD Zen 1 through Zen 4 were affected but the Google security engineers since discovered Zen 5 also could be impacted. BIOS updates are rolling out to address this signature verification issue while the Linux kernel is also being patched for microcode protections on Zen 5...

Intel Linux Graphics Driver Will Now Be Less Restrictive Over RAM Use

Phoronix - Thu, 04/10/2025 - 18:52
A change merged yesterday to the Intel Mesa graphics driver code lessens a restriction around the amount of system memory (RAM) that can be used by processes for the Vulkan system heap. This will allow more games/apps to work with the Intel integrated graphics that previously exceeded the driver-enforced limits but at the risk of running into broader out-of-memory behavior if under too much memory pressure...

Gzip 1.14 released earlier today as the first new release to this widely-used file compression format on Linux systems and other platforms...

New Patches Aim To Improve Unicode Support For The Linux VT Console

Phoronix - Thu, 04/10/2025 - 18:14
While there are efforts underway to effectively kill the Linux virtual terminal "VT" console by punting the functionality off to user-space, it's not dead yet and a new patch series out on Wednesday aims to enhance the modern Unicode handling by the Linux VT...

RADV Driver Now Emulates Ray-Tracing By Default For Older AMD GPUs For A Newer Game

Phoronix - Thu, 04/10/2025 - 17:46
Mesa's Radeon Vulkan driver "RADV" is now exposing its emulated ray-tracing support by default for older AMD Radeon GPUs even without any form of hardware-accelerated ray-tracing in order to run the new Indiana Jones game. It turns out even the emulated RT mode is fast enough to allow various older AMD Radeon graphics cards to be playable with this title...

Gallium Nine Has Been Deprecated, Planned For Removal In Mesa 25.2

Phoronix - Thu, 04/10/2025 - 17:24
Long before the likes of DXVK for Direct3D APIs implemented atop Vulkan, and even before the Vulkan API was conceived, there's been Gallium Nine as a Direct3D 9 state tracker implementation for Gallium3D. Gallium Nine showed promise in its early days for speeding up D3D9 Windows games running atop Wine on Linux. But with DXVK working out better these days and Gallium Nine no longer being maintained in recent times, it's now deprecated and set for removal later this year...
