While last week's Linux 5.7-rc6 kernel was quite big, Linux 5.7-rc7 is out today and it's on the smaller side of things in reassuring Linus Torvalds that the stable release of this kernel can happen soon.
Stemming from recent kernel discussions over a hypothetical new system call for reading small files more efficiently, Greg Kroah-Hartman has been working on the readfile() system call and it's looking like it is taking shape well enough to premiere soon in a new mainline kernel release.
For those AMD Ryzen laptop users eager to see the Sensor Fusion Hub driver for supporting the different hardware sensors on these AMD Zen laptops, that driver still isn't going to be merged for the upcoming Linux 5.8 cycle even after the patches were first published months ago.
While modern AMD EPYC CPUs support Secure Encrypted Virtualization (SEV) and Intel more recently has been working on MKTME for similarly offering hardware-backed total memory encryption, an Intel open-source engineer has now proposed a software-based solution for protected memory support for KVM virtualization.
Ardour 6.0 is now available as the latest major release of this high-end yet open-source digital audio workstation (DAW) package that runs across all major platforms.

When it comes to the support for AMD Ryzen 4000 "Renoir" laptop support under Linux, as outlined in my testing so far this month the main caveat is needing Linux 5.6~5.7 for good graphics support but on the likes of Ubuntu 20.04 LTS with Linux 5.4 you will not have GPU acceleration. At least in the case of the Lenovo IdeaPad 5 I have been using to test, you also need Linux 5.7 Git for battery sensor support. Another item that in turn is coming with Linux 5.8 is CPU temperature reporting for the Renoir processors.
