AMD Zen 4 vs. Zen 4C Performance, Zen 4C Core Scaling With Ryzen 5 8500G

Thu, 02/29/2024 - 03:22
Besides the integrated RDNA3 graphics making the Ryzen 8000G series desktop APUs interesting, making the AMD Ryzen 5 8500G a fun benchmarking target besides its sub-$200 price tag is having a mix of Zen 4 and Zen 4C cores. Here are some benchmarks looking at the Zen 4 vs. Zen 4C performance and power efficiency when offlining various core combinations on the Ryzen 5 8500G desktop processor.

FUSE Passthrough Support May Land For Linux 6.9 To Help Boost I/O Performance

Wed, 02/28/2024 - 22:36
Being worked on and off for several years has been FUSE read/write passthrough support for improving the performance of File-Systems in User-Space by avoiding the daemon overhead on a per-file basis where read/write operations are forwarded by the kernel directly to the lower file-system rather than the FUSE daemon. FUSE passthrough mode has shown to be a big performance win and it looks like it could be finally mainlined come Linux 6.9...

Intel Xe Kernel GPU Driver Starts Landing SR-IOV Bits & Other Features For Linux 6.9

Wed, 02/28/2024 - 20:00
Upstreamed for Linux 6.8 is the experimental Xe kernel graphics driver that is a modern replacement to the "i915" Direct Rendering Manager driver. The Xe kernel driver targets Tigerlake graphics and newer while it won't be until Lunar Lake / Xe2 when it aims to become the default driver for Intel iGPU/dGPU graphics. For the upcoming Linux 6.9 kernel merge window are more feature changes and fixes to this new open-source Intel kernel graphics driver...

64K Kernel Page Size Performance Benefits For HPC Shown With NVIDIA's GH200 Grace CPU

Wed, 02/28/2024 - 01:00
By default the AArch64 kernel on Ubuntu and other Linux distributions tend to default to a standard 4K page size but for newer AArch64 hardware especially in the server/HPC space, there can be great benefits to using a 64K page size. As it's been a while since I last ran any 64-bit ARM 4K vs. 64K kernel page size benchmarks, while having remote access to the NVIDIA GH200 I ran a fresh comparison for looking at the performance advantages to switching over to a 64K page size kernel. These new 64K kernel numbers are shown alongside the recent AMD EPYC and Intel Xeon CPU reference benchmark results for a look at how the 4K vs. 64K page size affects the overall computing landscape.

Intel HFI Driver Can "Save Tons Of CPU Cycles" By Only Enabling Itself When Needed

Tue, 02/27/2024 - 19:42
The Linux kernel has supported the Intel Hardware Feedback Interface "HFI" via the "intel_hfi" driver since 2022 for bettering supporting Core hybrid processors. The Intel HFI can be used for communicating performance and energy efficiency capabilities of individual CPU cores of the system. In turn the Linux kernel can leverage Intel HFI details for better task placement among the available CPU cores/threads. With a new patch series, the Intel HFI driver can "save tons of CPU cycles" by only enabling it when needed...

Ubuntu Blog Talks Up Rust Schedulers, Potential For Micro-Kernel Design Future

Tue, 02/27/2024 - 09:27
Ubuntu/Canonical has for a while now promoted the prospects of Rust programming within the Linux kernel and one of their kernel engineers, Andrea Righi, wrote a Rust-written Linux scheduler with promising results that leverages eBPF for dynamically loading it at run-time. While Ubuntu isn't yet committing to using it as part of their distribution, appearing on the Ubuntu blog today was more praise for the work and even talking about the potential for a "micro-kernel design" in the future via leveraging Rust and eBPF...
