This page details currently supported features on all extant Apple Silicon Macs, as well as their upstream status. The tables can be interpreted as follows:
- Kernel release, e.g. 6.0: the feature was incorporated upstream as of this release
-
linux-asahi (kernel release): the feature is stable, available for use in
linux-asahi, and should be upstream by the release indicated -
linux-asahi: the feature is (mostly) stable and available for use in
linux-asahi -
asahi-edge: the feature is available for wider testing in the
linux-asahi-edgepackage in the linux-asahi Linux distribution - WIP: Development work on the feature is actively progressing, however is not yet ready for wider testing, use or distribution
- TBA: Active work on this feature is not being undertaken at this time

Notes
cpuidle situation
Some power management functionality on ARM machines is controlled via the PSCI interface. The kernel has a specific way of talking to PSCI that is not compatible with Apple Silicon, and a discussion is required with upstream maintainers in order to figure out the best way forward. Given that this discussion has failed to materialise for two years, the decision has been made to hack together a driver that directly calls WFI/WFE instructions in order to bring this functionality to Asahi Linux. This greatly improves the UX on laptops when coupled with energy-aware scheduling, as it resolves the issue of the machines running warm to the touch and significantly improves battery life. This can never be upstreamed, however the hope is that this hacked together driver becomes unnecessary at some point in the near future.
