IBM To Kernel Maintainer: "You Are An IBM Employee 100% Of The Time"

It's fairly common that many longtime Linux kernel developers use their personal email addresses for signing off on kernel patches or dealing with other patch work, especially when they are engaging with kernel development in their personal time too and occasionally jumping between employers over time while still sticking to interacting with the upstream kernel community, etc. There are also understandably some companies that mandate the use of their corporate email addresses for their official work/patches while now IBM seems to be taking things one step to the extreme.

KFence Memory Safety Error Checking Is Looking Good For Minimal Overhead On Linux 5.12

Of the many new features coming with Linux 5.12 is KFence, short for the Kernel Electric Fence. KFence is a low-overhead memory safety error detector/validator for the kernel with lower expected overhead costs than say the Kernel Address Sanitizer. I just wrapped up some benchmarks looking out for any overhead impact of KFence on Linux 5.12 in its near-final state.

AMD EPYC 7003 Series Performance In The Cloud With Microsoft Azure HBv3 HPC VMs

One of the exciting elements of last month's AMD EPYC 7003 "Milan" series launch was having same-day availability in public clouds. Microsoft as one of AMD's cloud partners worked closely to deliver launch-day availability in their public cloud using EPYC 7003 series processors with the new "HBv3" instances focused on high performance computing (HPC) virtual machines. Here are some benchmarks of the Azure HPv3 instances compared to prior generation Microsoft Azure HPC instances available on-demand in their cloud.

More Progress Is Made Understanding Apple's M1 GPU, Working Towards An Open Driver

Alyssa Rosenzweig, known for her work on the Panfrost open-source driver for Arm Mali graphics, has published the latest findings around the Apple M1 graphics processor. In fact, enough understanding to get a shaded, spinning cube rendering on the Apple M1 using a simple demo so far while the open-source driver support is still the goal.

Patches Resubmitted For Linux With Selectable Intel Graphics Platform Support

Back in early 2018 were patches proposed for selectable platform support when building Intel's kernel graphics driver so users/distributions if desired could disable extremely old hardware support and/or cater kernel builds for specific Intel graphics generations. Three years later those patches have been re-proposed.
