Linux Kernel 5.19 was released! Ubuntu Mainline PPA has made the packages for testing purpose.
Linus Torvalds announced this kernel release last night:
On a personal note, the most interesting part here is that I did the release (and am writing this) on an arm64 laptop. It’s something I’ve been waiting for for a _loong_ time, and it’s finally reality, thanks
to the Asahi team. We’ve had arm64 hardware around running Linux for a long time, but none of it has really been usable as a development platform until now.
Linux 5.19 Kernel features initial support for LoongArch CPU architecture, Apple M1 NVMe controller and Apple eFuse driver. There are also initial graphics driver for Raptor Lake P (Intel’s 13th generation processors), In-Field Scan (IFS) to circuit level tests on a CPU core, and bug-fix for Intel laptops running hot and draining the battery faster.
Other features include:
- Zstd compressed firmware support
- Google Whiskers Touchpad support.
- Lenovo X12 trackpoint support.
- Armv9 Scalable Matrix Extension support
- Big TCP and pureLiFi’s device driver.
