Loongson 2K1000 Linux Support Still Getting Brought Up With New Kernel Patches - Phoronix
Chinese MIPS64 vendor Loongson announced the 2K1000 back in 2017 and while it has already been succeeded by more advanced chips in the Loongson 3 series, the Linux driver support for the 2K1000 is still coming together.
The Loongson 2K1000 is their dual-core 40nm part from 2017 that has around a 1.0GHz clock frequency for the MIPS64r2 LoongISA 1.0 processor. While Loongson generally enjoys good Linux support for their hardware, it's taken a while for this 2K1000 support to come together.

Linux 5.12 Performance Is Looking Stable, In Good Shape - Phoronix
With that nasty swapfile issue behind us, the Linux 5.12 kernel is looking to be in good shape and on my tests so far across a number of different Intel and AMD systems I am not seeing any major surprises.
Long story short, aside from areas of noted changes for Linux 5.12, I am not seeing any benchmarks come out with unexpected results for better or worse. For one week now across continuous testing on many different systems, Linux 5.12 is looking to be in good shape and reliable with that swap fix causing no more file-system regressions.
I haven't hit any major regressions either, unlike Linux 5.11 that was impacted by the AMD frequency invariance issue.

This virtual sound driver has been floated on the kernel mailing list while this week was queued up by sound maintainer Takashi Iwai of SUSE.

Samsung, Red Hat to Work on Linux Drivers for Future Tech
The metaverse is expected to uproot system design as we know it, and Samsung is one of many hardware vendors re-imagining data center infrastructure in preparation for a parallel 3D world.
Samsung is working on new memory technologies that provide faster bandwidth inside hardware for data to travel between CPUs, storage and other computing resources. The company also announced it was partnering with Red Hat to ensure these technologies have Linux compatibility.
