For months we have seen various Intel open-source Linux graphics driver patches that begin preparing for multi-GPU support where in moving forward with their Xe graphics cards there could be the iGPU + dGPU setup or even multiple Xe graphics cards in a single system. So far those Intel Linux multi-GPU preparations have been focused on their kernel-space driver while now it's reaching into user-space with their Vulkan driver seeing early infrastructure changes...

Following last month's Debian init system diversity vote where the Debian developers decided on a general resolution of focusing on systemd but support exploring alternatives, the official Debian Policy has been updated to reflect that...

One of the changes planned for Fedora 32 has been to enable EarlyOOM by default to better handle low memory situations either due to the system running with minimal RAM or under memory pressure. But the Fedora Engineering and Steering Committee has yet to reach a decision over this default...

Earlier this month many Phoronix readers were interested in our fresh tests of the XanMod-patched Linux kernel for boosting the desktop and workstation performance compared to Ubuntu's default Linux kernel. Among many patches, XanMod does pull in some kernel patches from Intel's performance-optimized Clear Linux, so we figured it would be interesting to see how the XanMod'ed Ubuntu compares to Clear Linux performance.

One of several projects implementing the OpenGL graphics API over Vulkan has been Think Silicon's GLOVE library. GLOVE currently is focuses on OpenGL ES 2.0 + EGL 1.4 support and is a standalone project unlike Mesa's Zink Gallium3D driver working on OpenGL / GLES over Vulkan too. GLOVE 0.4 is out today as a big feature update...

Last week I eagerly reported on Ryzen CPUs on Linux finally seeing CCD temperatures and current/voltage reporting thanks to new patches to the k10temp driver by Google's Guenter Roeck who oversees the kernel's hardware monitoring "HWMON" subsystem. The patches seem to be working well and are tentatively queued in hwmon-next, but more testing is still needed...

While there has been the initial Microsoft exFAT file-system driver since Linux 5.4, that code is based on a vintage snapshot of prior Samsung code. Samsung engineers meanwhile have been working to upstream a much newer and better off exFAT implementation to replace that existing driver and it looks like it could be ready for Linux 5.6...
