Linux Patched For Unsafe Xen Behavior Around CPU Speculative Attack Protections

Phoronix - Wed, 12/18/2024 - 05:36
Merged today to the Linux kernel are fixes for two vulnerabilities with the Xen hypervisor. One of them concerns a malicious network backend being able to crash a guest after a suspend/resume cycle of a Linux guest. The other more pressing issue addressed is a Xen hypercall page being unsafe against speculative CPU attacks...

Windows 11 vs. Linux Benchmarks For Intel Arc B-Series "Battlemage" Shows Strengths & Weaknesses

Phoronix - Wed, 12/18/2024 - 00:03
Last week with the availability of the Intel Arc B-Series Battlemage graphics cards I ran benchmarks looking at the GPU compute performance, Linux gaming benchmarks, and also the workstation graphics capabilities. The Intel Arc B580 graphics showed some nice generational uplift under Linux for most workloads but there were some anomalies where clearly the Intel Linux graphics driver had room to better optimize the new Xe2/Battlemage graphics support. Windows benchmarks of the Intel Arc B580 also showed it performing more competitively to the likes of the GeForce RTX 4060 compared to what I was seeing under Linux. Thus I spent the past few days working on some Windows 11 vs. Ubuntu Linux graphics benchmarks for both Intel Arc Graphics of Alchemist and Battlemage GPUs to see how the performance compares.
