With that, Red Hat developers working on Fedora have been working on an "Enterprise Linux Next" proposal to not only vet such x86_64 build changes but also to provide a feedback workflow for other changes...

When it comes to the AMD EPYC 7002 "Rome" processors we have looked at the various higher-end SKUs since their launch last August up to and including the EPYC 7742 with its 64 cores / 128 threads per socket. But for those wondering about the EPYC 7002 series performance at the bottom end of the spectrum, here are some fun benchmarks of the EPYC 7232P and EPYC 7262 on the near-final Ubuntu 20.04 LTS state compared to various vintages of Intel Xeon CPUs -- most notably, a curiosity driven look at the 8 core / 16 thread Intel Haswell Xeon performance.

File this under the "I can't believe it took this long" or "why wasn't this done before" section... Thanks to SUSE, there are finally patches pending to allow easily setting sysctl parameters from the kernel command line using a generic infrastructure...

Going back to over a year ago were discussions by Oracle engineers and others about a secure launch boot protocol for the Linux kernel to in turn tie into the Trenchboot open-source project working on various system integrity features. We are now finally seeing new patches out of Oracle for wiring more Trenchboot support into the Linux kernel...

Disclosed back in mid-November was the Intel JCC Erratum that required a CPU microcode update to mitigate and that in turn had broad performance hits. But via toolchain updates, some of that overhead can be offset. The GNU Assembler patches were quickly merged and new options exposed for helping to decrease that performance hit but on the LLVM side the developers are still working on their mitigation with some design decisions still to be made...

Introduced into the Linux 4.18 kernel back in June 2018 was the new RSEQ system call for "Restartable Sequences" to provide faster user-space operations on per-CPU data by avoiding atomic operations updates. Sadly, seeing user-space make use of RSEQ has been a slow process...

Doom Eternal was released this week by id Software as their first game atop the Vulkan-focused id Tech 7 engine. While it's another id Software game not seeing a native Linux port, with some tweaking the game can run under Steam Play / Proton.

We are used to seeing tier-one Linux distributions outperforming Microsoft Windows on hardware ranging from $199 laptops to HEDT and server processors and everything in between. Thus it came as a large surprise to us when finding Windows 10 outperforming multiple Linux distributions on a new Intel laptop. Not only was Windows 10 leading, but the performance paradigm shifted that Ubuntu was even outperforming Clear Linux, which normally is the fastest of Linux distributions out-of-the-box.

The release cycle was dragged out an extra month due to bugs and there ended up even being a last minute sixth release candidate yesterday, but LLVM 10.0 and its sub-projects like Clang 10.0 and LLDB 10.0 were just tagged...
