Expected to be squared away in time for the Linux 6.3 kernel cycle, which is kicking off in February, is Automatic IBRS as a new feature of Zen 4 processors. The patches already have been queued up into TIP's x86/cpu branch so barring any issues will be all wired up for this next kernel version. Automatic IBRS can provide better performance than the Retpolines implementation used currently on Zen 4 and prior CPUs as part of the Spectre V2 mitigations. With the switch over to Automatic IBRS for Zen 4, it means better performance in some areas as shown by these benchmarks today with AMD 4th Gen EPYC "Genoa" processors.

The open-source WinGet package manager is approaching three years since its announcement while it continues to not be as rich and robust of what Linux users for many years have enjoyed, but in any case it's continuing to be improved...

There still is another month to go until the Linux 6.2 kernel is released as stable and in turn kicking off the Linux 6.3 merge window. But from my monitoring in recent weeks, here is an early preview of some of the material expected for the v6.3 kernel based on what's been queuing in the various subsystem "-next" branches or otherwise looking like it should align for the next cycle...
