AMD Ports Register Shadowing To The Mesa RADV Vulkan Driver

Phoronix - Sat, 01/28/2023 - 00:00
Most of the Mesa Radeon Vulkan "RADV" driver development has been done by the likes of Valve, Google, and Red Hat engineers with it being an "unofficial" driver while AMD supports AMDVLK as their official open-source Vulkan driver as well as supporting their closed-source AMDGPU-PRO Vulkan driver too that shares common code with their Windows Vulkan driver. It was pleasant to see AMD this week though submitting new feature code to RADV...

Linux Developers Evaluating New "DOITM" Security Mitigation For Latest Intel CPUs

Phoronix - Fri, 01/27/2023 - 20:00
Last summer Intel published guidance around the Data Operand Independent Timing (DOIT) instruction mode that can be enabled with recent generations of Intel processors to ensure constant time execution for a subset of the Intel instruction set, which can be particularly important for cryptographic algorithms. Linux kernel developer discussions fizzled out last year over handling this DOIT functionality for what is described as a CPU vulnerability with recent Intel CPUs. However, now a Linux kernel patch from a Google developer would enable this change unconditionally for newer Intel CPUs but raises performance concerns.

Intel Releases HAXM 7.8 As One Last Hurrah For The Open-Source Project

Phoronix - Fri, 01/27/2023 - 18:55
Earlier this month Intel announced they would be discontinuing development of HAXM as a hardware-accelerated execution manager that's been popular on Windows and macOS for Android emulation. While the original announcement discontinued its development immediately, they decided to go ahead and put out one final version: Intel HAXM 7.8 is available today for concluding this open-source project...

Microsoft's Dzn Mesa Driver Already Hits Vulkan 1.2

Phoronix - Fri, 01/27/2023 - 18:45
Microsoft engineers seem to be working on getting the Dozen "dzn" Mesa driver up to speed as quickly as possible. It was just earlier this month it began passing nearly all Vulkan 1.0 conformance tests, Vulkan 1.1 was then exposed just a few days ago, and now Dzn is ironing out Vulkan 1.2...

Linux Resource Control Monitoring Being Improved For Intel Sub-NUMA Cluster Configurations

Phoronix - Fri, 01/27/2023 - 16:00
For those making use of Intel's sub-NUMA cluster (SNC) configuration option available on their servers since Skylake, the Linux resource control "resctrl" kernel code is being improved upon to better handle this resource configuration...
