Expected to be introduced in the upcoming Linux 6.19 kernel cycle is the ASUS Armoury “asus-armoury” driver for enhancing support for the ASUS ROG Ally gaming handhelds and other ASUS enthusiast/gaming devices under Linux.
The ASUS Armoury driver was born out of the existing ASUS WMI driver but overhauling it with a clean and more well defined API. The ASUS Armoury driver provides new BIOS attributes using the fw_attributes_class while deprecating all the existing attributes from the ASUS-WMI driver with plans to then remove them in the next Linux LTS kernel version.
Linux is a “monolithic kernel” where lots of things like drivers and services are inside it, apprently making it faster than a microkernel.
