Pinned Device Memory Patches For Intel's Multi-GPU "Project Battlematrix" Linux Efforts

Phoronix - Wed, 08/20/2025 - 00:12
As part of Intel's ongoing Project Battlematrix efforts that include SR-IOV support for Arc Pro cards as well as multi-device (multi-GPU) support for allowing up to eight Intel Arc Pro graphics cards in a single system, today Intel engineers posted their preliminary Linux driver patches for pinned device memory functionality that is important for multi-GPU usage...

Rusticl vs. AMD ROCm Performance On Ryzen AI Max+ "Strix Halo"

Phoronix - Tue, 08/19/2025 - 22:00
One of the set of tests I have been meaning to carry out for a number of months has been comparing the Mesa Rusticl performance to different dedicated hardware drivers. Rusticl is the Rust-based OpenCL 3.0 driver within Mesa that works across Gallium3D drivers and over the past many months has been maturing rather well. Among the targets I have been wanting to compare is how well Rusticl competes with the AMD ROCm OpenCL implementation for Radeon GPUs. Given all the interest recently around Strix Halo and the Framework Desktop as well, today's benchmarking is looking at the performance between these different OpenCL driver implementations for the Radeon 8060S Graphics.

Linux Adding Detection For BSD's Bhyve Hypervisor To Support 255+ vCPUs

Phoronix - Tue, 08/19/2025 - 19:52
Bhyve is the BSD hypervisor / virtual machine manager (VMM) developed by FreeBSD that supports a range of operating systems and across CPU vendors. With time Bhyve has also been ported to other BSDs and even Illumos and macOS. The Linux kernel is now in the process of adding guest detection for the Bhyve hypervisor in order to support VMs with 255+ vCPUs...
