Retbleed Impact, Overall CPU Security Mitigation Cost For Intel Xeon E3 v5 Skylake

28. Červenec 2022 - 10:55
Since the disclosure of Retbleed earlier this month as the newest CPU security vulnerability around speculative execution, I've posted some Intel/AMD benchmarks looking at the mitigation cost for the affected older generations of processors. Last week I also looked at the accumulated CPU mitigation cost on AMD Zen 1. Today is a similar comparison over on the Intel Xeon E3 v5 "Skylake" side with looking at the cost of just the Retbleed mitigations and then the overall CPU mitigation cost when toggling all of the various vulnerabilities with the "mitigations=off" flag.

Open-Source NVIDIA "Nouveau" Driver Refactors Some Display Code For Linux 5.20

27. Červenec 2022 - 10:12
While AMD and Intel are busy with big graphics driver changes for each new version of the Linux kernel, the open-source NVIDIA "Novueau" kernel driver that is largely just worked on by Red Hat employees is just stumbling along. NVIDIA in May announced they are transitioning to an open-source kernel driver approach, but that current kernel driver is not in shape for upstreaming and due to the heavy use of the GPU System Processor (GSP) that source release hasn't been a huge help yet for the reverse-engineered Nouveau driver. With the upcoming Linux 5.20, Nouveau has some display patches...
