AMD Ports Register Shadowing To The Mesa RADV Vulkan Driver

Phoronix - 27. Leden 2023 - 17:00
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 - 27. Leden 2023 - 13:00
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.
