Thanks to kernel patches, pushed onto Linux 7.2 mainstream and [Gentoo overlay](https://github.com/miasvanklei/Gentoo-overlay), most of the previous features which this release lacked (stable suspend on GNOME, accelerometer sensor, dedicated video output, cameras) are now implemented. The project has diverged into [patched kernel](https://sayag.it/fedora-linux-surface-pro-12in/kernel-surface.git) + [libcamera](https://sayag.it/fedora-linux-surface-pro-12in/libcamera.git) builds with an [RPM repo](https://rpm.sayag.it/kernel-sp12in/) publicly available.
