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.

With Intel DG2/Alchemist getting settled, the DRM-Next cutoff for v5.20 kernel material having passed, and Raptor Lake enablement also appearing to be in good shape given the little change over Alder Lake, Intel open-source engineers have begun working more on Meteor Lake driver support that will succeed Raptor Lake next year...

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...

Earlier this year I wrote about the Intel Idle driver support being prepared for Xeon "Sapphire Rapids" CPUs but a limitation with these forthcoming Xeon Scalable processors was that C1 and C1E c-states handling are now mutually exclusive. Unlike earlier Xeon processors, C1 and C1E states couldn't be enabled at the same time. Fortunately, via new Intel firmware they have managed to overcome this limitation...

Last week when posting my initial Linux benchmarks of the AMD Ryzen 7 PRO 6850U performance (and also looking at the AMD Rembrandt Windows vs. Linux speed), there were two main areas to get excited about with these AMD Zen 3+ SoCs: nice power efficiency improvements across many real-world workloads and the graphics upgrade with the integrated Radeon 680M. In this article are more tests of the Radoen 680M graphics looking at the integrated graphics speed-up with RDNA2 finally replacing Vega as a big upgrade and also how this compares to the Intel Alder Lake P Xe Graphics performance for Linux laptops.
