M4 Series Feature Support
This page details currently supported features on all M4 series (M4, M4 Pro, M4 Max) Apple Silicon Macs, as well as their progress towards being upstreamed. The tables herein 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 Fedora Asahi Remix and in
linux-asahi - asahi-edge: the feature is (mostly) stable and available for use in Fedora Asahi Remix. For historical reason it is available 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
If a feature is not ready, then there is no estimation on when it will be ready. Please do not ask for estimations in support channels (e.g. IRC).
