Step-by-step install guides
Distro-specific information
Work-in-progress branches
Important fixes and support for new features (once stable enough) can be found in my X13s (sc8280xp) wip branches, for example:
https://github.com/jhovold/linux/tree/wip/sc8280xp-6.13-rc1
These branches also include a minimal (but functional) johan_defconfig that serves as documentation for the configuration options that need to be enabled for the X13s.
Kernel command line
To boot Linux the following kernel parameters need to be provided:
clk_ignore_unused pd_ignore_unused arm64.nopauth efi=noruntime
due to a generic resource handover issue and a couple of firmware bugs, respectively.
With recent UEFI firmware efi=noruntime can be left out when the Linux Boot option is enabled.
