Mesa 20.3 Lands Rewritten AMD Zen L3 Cache Optimization

You may recall going back to 2018 that well known open-source AMD Mesa driver developer Marek Olsak was working on Mesa optimizations around the AMD Zen architecture. In particular, better handling of Mesa for Zen's L3 cache design. A rewritten implementation of that has now landed along with some other improvements.

Oracle Continues Building DTrace For Linux Atop BPF

More than a decade ago Linux users tended to be envious of Sun Microsystems' Solaris for ZFS and DTrace as the two most interesting technical selling points of the platform. In that time OpenZFS is now extremely vibrant for offering ZFS on BSD and Linux systems while DTrace is barely brought up these days. This tracing framework originally developed for Solaris was fantastic back in the day but over the years Linux has stepped up its game with various efforts. Now as we hit the end of 2020, Oracle engineers continue working on bringing better DTrace support to Linux.

AMD Navi "Blockchain" Card Support Being Added To Linux 5.10

Last week we were first to report on a PCI ID being added for a Navi 1 "Blockchain" graphics card without display outputs and seemingly focused on cryptocurrency mining. This card wasn't talked about at yesterday's Radeon RX 6000 series launch but that support is now on the way to the Linux 5.10 kernel.

SiFive Is Launching The Most Compelling RISC-V Development Board Yet

If you've been waiting to port your software to RISC-V until having a decent RISC-V system where you can develop on-host, wanting to experiment with the libre processor architecture or even use it as a daily desktop system, or just wanting a Linux system that's not x86_64 / ARM / POWER, SiFive today is announcing a new board today that is the most promising yet. The SiFive HiFive Unmatched is the best RISC-V development board we've seen to date and the closest to being the first "RISC-V PC" for Linux use.

Intel's oneDNN Continues Improving Support For Non-Intel Hardware

Earlier this year was the surprising move of Intel's oneDNN neural network library adding AArch64 support and that was then complemented by adding IBM POWER support to this neural network library that is part of their oneAPI collection. Now with the latest oneDNN 2.0 beta they have furthered the support and performance for non-Intel hardware.

Mesa 20.3 Supports Intel Alder Lake Gen12 Graphics

Last week Intel open-source engineers began publishing Linux kernel patches for the "Alder Lake S" graphics support. That work should be found in the Linux 5.11 cycle being christened as stable in early 2021. In user-space, Alder Lake graphics patches also appeared for their OpenCL / oneAPI Level Zero compute stack and now merged into Mesa 20.3 as well for OpenGL / Vulkan support.

The Linux Kernel Looks To Eventually Drop Support For WiMAX

With the WiMAX 802.16 standard not being widely used outside of the Aeronautical Mobile Airport Communication System (AeroMACS) and usage in some developing nations, the Linux kernel may end up dropping its support for WiMAX but first there is a proposal to demote it to staging while seeing if any users remain.

Corsair Power Supplies May Soon See Sensor Support Exposed Under Linux

Select high-end Corsair power supplies such as their RMi / HXi / AXi series are able to expose various sensor metrics via USB interface to the system. To date this sensor functionality has only worked under Windows with their proprietary software but now an open-source driver is seeking mainline inclusion for supporting these sensors under Linux.
