AMD-specific code within Linux's KVM virtualization component previously could allow a KVM guest to breakout into the host. This bug persisted in the Linux kernel from late 2020 to March 2021 before being addressed and is the first known issue of such a guest-to-host breakout that didn't also depend upon bugs within user-space components...

After looking recently at the FreeBSD 13.0 and DragonFlyBSD 6.0 performance on AMD EPYC 7003 "Milan" using a Tyan Transport CX GC68-B8036-LE server, the next round of benchmarking from this server with AMD EPYC 7543 32-core processor was looking at its support (all tested 2021 Linux distributions were running fine on this latest-generation AMD server) and performance across 11 current Linux distribution releases from Arch, CentOS, Clear Linux, Debian, Fedora, Rocky Linux, Ubuntu, and openSUSE.

While Xeon Scalable "Sapphire Rapids" was talked about for launching in late 2021, that was widely expected to be delayed. Intel today proactively confirmed that Sapphire Rapids will now begin production in Q1'2022 with their ramp beginning in Q2'2022...

Intel is going to be disabling Transactional Synchronization Extensions (TSX) by default for various Skylake through Coffee Lake processors with forthcoming microcode updates. Yes, this does mean performance implications for workloads benefiting from TSX. This change has seemingly not been talked about much at all publicly and I just happened to become aware of it when looking through new kernel patches...

Following yesterday's release of the Linux 5.13 kernel, the GNU folks have released GNU Linux-libre 5.13-gnu as their downstream that strips out support for loading binary-only firmware/microcode, blocks the ability to load binary-only kernel modules, and other sanitization work in the name of software freedom...
