It is a bit involved at the moment, and I haven't tried on a laptop (the nice thing about the Mini is that you can bury it under a pile of other machines and still make use of it). > Can I find something resembling a specification for the Apple > interrupt controller, or the only available documentation is in the > Linux driver and patches on the mailing list? The Asahi wiki has a bunch of RE goodies, but you really don't need to know much about the HW to follow what this series does. Actually, you instead need to understand what the GIC guarantees to the guest, because this is all about the GIC emulation on a non-GIC interrupt controller. Thanks, M. -- Without deviation from the norm, progress is not possible.
