NVK Now Vulkan 1.4 Conformant For NVIDIA Maxwell GPUs

Phoronix - Wed, 04/23/2025 - 02:01
Mesa's NVK Vulkan driver had been Vulkan 1.4 conformant for Turing and newer GPUs, but now with Mesa 25.2-devel it's Vulkan 1.4 conformant going back to Maxwell GPUs. This change is exported to be back-ported to the upcoming Mesa 25.1 release as well for those interested in using this open-source NVIDIA Vulkan driver...

AMD Ryzen AI Max 300 "Strix Halo" Graphics IP Versions Confirmed

Phoronix - Wed, 04/23/2025 - 00:27
For those that have been wondering about the Linux support and more details around the Ryzen AI Max 300 "Strix Halo" APUs on Linux, here's a brief update...

Intel Core Ultra 9 285K "Arrow Lake" Performance On Linux Has Improved A Lot Since Launch

Phoronix - Tue, 04/22/2025 - 22:00
Today's Linux benchmarking at Phoronix is looking at how the Intel Core Ultra 9 285K performance has evolved since its launch last October. Taking the launch-day benchmarks from October with the same hardware, we are revisiting the Intel Arrow Lake performance under Linux today using the newest system BIOS and the newly-released Ubuntu 25.04 for seeing how the performance has evolved roughly over the past half-year.

Phoronix - Tue, 04/22/2025 - 21:41
One of the early features being merged for what will become the GCC 16 compiler following last week's GCC 15 code branching is CPU targeting support for the XuanTie RISC-V processors...

Kmemdump Proposed For The Linux Kernel To Help With Memory Dumping & Debugging

Phoronix - Tue, 04/22/2025 - 20:28
Eugen Hristev of Linaro sent out a "request for comments" patch series today proposing kmemdump for the Linux kernel as a new means to assist in debugging driver/system problems by making it easier to dump memory for specific areas/regions...

Linux Being Patched For Buggy MWAIT Behavior On Intel Ice Lake Servers

Phoronix - Tue, 04/22/2025 - 18:59
The Linux kernel has seen safeguards for select prior Intel CPU cores due to bugs around the MONITOR/MWAIT implementation with the processors. MWAIT/MONITOR bugs was found to be the cause of annoying issues at boot for Lunar Lake laptops and also previously plagued Goldmont Atom cores. It also turns out that Ice Lake servers can be subject to similar MWAIT/MONITOR behavior...

Intel Vulkan Linux Driver Begins Prepping For Ray-Tracing Changes With Xe3

Phoronix - Tue, 04/22/2025 - 18:34
Merged yesterday to Mesa Git for next quarter's Mesa 25.2 release is an improvement for the Intel Vulkan ray-tracing code with an eye on next-gen Xe3 graphics hardware...

Linux Patch Queued To Report Outdated Intel CPU Microcode As A Vulnerability

Phoronix - Tue, 04/22/2025 - 04:55
Last year a patch was raised for the Linux kernel that would report outdated CPU microcode versions as a security vulnerability. With Intel routinely issuing new CPU microcode updates for security vulnerabilities and addressing other functional issues, the Linux kernel would begin warning users when recognizing that outdated CPU microcode is deployed for a given processor. That patch has now been queued into a tip/tip.git branch and thus looking like it will be submitted for the upcoming Linux 6.16 kernel cycle...
