NVK Now Vulkan 1.4 Conformant For NVIDIA Maxwell GPUs

22. Duben 2025 - 19:01
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...

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

22. Duben 2025 - 11:59
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

Linux Patch Queued To Report Outdated Intel CPU Microcode As A Vulnerability

21. Duben 2025 - 21:55
Last year a patch was raised for the Linux kernel that would report outdated CPU microcode versions as a security vulnerability.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and addressing other functional issues, the Linux kernel would begin warning users when recognizing that outdated CPU microcode is deployed for a given processor.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...

AMD ROCm 6.4 Adds SPIR-V Linking Support To HIP

21. Duben 2025 - 20:58
With the recently released AMD ROCm 6.4 release for this open-source GPU compute stack for Radeon and Instinct hardware there are yet more indications around AMD's growing software ecosystem expansion. With ROCm 6.4 are additions to the HIP API for allowing linking of SPIR-V code objects, which is the intermediate representation used by Vulkan as well as with OpenCL and other Khronos APIs...

GCC Patch Revived For -mtune=generic Showing Nice Benefits On Intel & AMD CPUs

21. Duben 2025 - 18:26
A 2021 era patch for the GNU Compiler Collection (GCC) has been revived and discussed in recent days around simplifying the memcpy and memset inlining strategies when compiling code with the "-mtune=generic" option. The patch takes the approach during that generic tuning to try to avoid branches. In doing so, some nice performance benefits are observed in some benchmarks...

Ubuntu 25.04 vs. Windows 11 CPU Performance For The AMD Ryzen AI 7 PRO 360

21. Duben 2025 - 13:16
Earlier this month was a look at the AMD RDNA 3.5 graphics between Windows 11 and Ubuntu 25.04 using a Ryzen AI 7 PRO 360 "Strix Point" SoC within a Lenovo ThinkPad T14s Gen 6. That was an interesting benchmark battle and providing a fresh look at the open-source AMD Linux graphics driver stack relative to Radeon Software on Windows. For those curious about the current Zen 5(C) performance, today's article are all of the CPU benchmarks for the AMD Ryzen AI 7 PRO 360 performance under the newly-released Ubuntu 25.04 and Windows 11 as pre-loaded by Lenovo.

NVIDIA Engineer Posts New NOVA Driver Patches - Still Far From Doing Anything Useful

20. Duben 2025 - 13:51
Merged for the Linux 6.15 kernel were the very early boilerplate code around the NOVA driver as a new, open-source and Rust-written NVIDIA Linux kernel graphics/display driver. This successor to the Nouveau kernel driver is going to leverage the NVIDIA GPU System Processor (GSP) to make it easier to develop and maintain this open-source driver. But depending upon the GSP also means the NOVA driver will only work with RTX 20 class GPUs and newer. This driver is going to be built up gradually within the mainline Linux kernel and coming out this Easter were a new set of 16 patches for further laying the NOVA groundwork...
