While Intel has been making steady progress around enhancing the Linux kernel handling for CPUs with a mix of P and E cores for proper task placement and power optimizations, one area that still is less than desirable for these hybrid Intel Core processors is around virtualization. But Intel engineers are now actively working on improving the Linux virtualization infrastructure for being able to convey the P/E core differences among vCPUs so that the guest VMs can better behave in such environments...

While there were many Windows reviews/benchmarks out Tuesday for Intel Core Ultra 200 Series "Lunar Lake" laptops on various websites, Linux tests are still awaiting due to having resorted to pre-ordering a Lunar Lake laptop myself for delivering Linux support/compatibility information and performance benchmarks. But hopefully by this time next week will be the initial data set...

While open-source enthusiasts like to criticize NVIDIA for not maintaining upstream, in-tree kernel graphics driver support (though things have been changing there), for other areas of their vast hardware portfolio they are much better upstream Linux kernel citizens and often at the forefront of new driver innovations. One of the leading examples of that is around the NVIDIA Mellanox networking driver support. With Linux 6.12 they've landed a new feature that has been described as "a sign of things to come, I think we will see more of this in the next 10 years."..

NVIDIA engineers have sent out an exciting set of Linux kernel patches for enabling NVIDIA vGPU software support for virtual GPU support among multiple virtual machines (VMs). In aiming for upstream-focused Linux support, this NVIDIA vGPU support is built around the adapted Nouveau driver with the code previously posted for splitting up the Nouveau/NVKM driver components...

With the Intel Xeon 6900P "Granite Rapids" launch today the review embargo has now expired. I began with my Intel Granite Rapids Linux benchmarking a few days ago and have initial benchmarks to share for the flagship Xeon 6980P processors paired with MRDIMM 8800MT/s memory. This is just the beginning of a lot of Granite Rapids benchmarks to come on Phoronix. Compared to the existing AMD EPYC competition and prior generation Intel Xeon processors, the Xeon 6900P series performance surpassed my expectations and has debuted as an incredibly strong performer. In some areas of HPC and other workloads, Intel is able to regain leadership performance with Granite Rapids paired with MRDIMMs. In AI workloads where the software is optimized for AMX, the new Xeon 6900P CPUs can showcase staggering leads.

Building off the launch earlier this year of the first Xeon 6 processors with the Xeon 6700E "Sierra Forest" processors, today Intel is lifting the wraps on the much anticipated Xeon 6900P "Granite Rapids" processors. Where as Sierra Forest is optimized for power efficiency and core density, the Intel Xeon 6 P-core processors are optimized for per-core performance and have shown some very strong generational uplift -- and against the AMD competition -- as we'll show today in the first Xeon 6980P Linux benchmarks.

Intel used their Enterprise Tech Tour last week in Oregon to not only provide insight into the new Xeon 6900 "Granite Rapids" server processors (and Xeon 6980P benchmarks) but also to shed more light on their Gaudi 3 AI inference accelerator. The question I was most curious about with Gaudi 3: where's the Linux driver support?..

It's pretty much a given that the Compute Module 5 will come, it's just a matter of when. With recent activity by Canonical engineers working on Ubuntu Linux, it's looking like the CM5 could be here soon...

When it comes to the question of the fastest x86_64 Linux distribution the answer is very easy with Intel's Clear Linux. But what about in the AArch64 world? When having the AmpereOne server in the lab curiosity got the best of me and I ran benchmarks across seven different Linux distributions on this Supermicro ARM server for seeing what platform had the fastest out-of-the-box Linux performance. The Linux distributions tested on this AmpereOne A192-32X server included Ubuntu 24.04 LTS, Ubuntu 24.10 daily, Fedora Server 40, AlmaLinux 9.4, openSUSE Tumbleweed, Debian Testing, and CentOS Stream 10.
