Hi, I am working on a thunderbolt driver for Mac Books (see [1] if you are interested). I have got basic hotplug working but I am still struggling with suspend issues. The problem is that ACPI will cut power to the controller during startup/suspend/resume whenever it does not detect Darwin. Furthermore the ACPI method which could be used to re enable power is inactive if Darwin is not detected. I have tried to use acpi_osi to make the firmware believe that it is running Darwin. This does work but breaks other stuff (the firmware contains a lot of OS specific code paths, for example _OSC breaks...). My question would then be whether there exists a more user friendly alternative to a custom DSDT? My plan is to somehow exchange/modify a few ACPI methods from within my driver. Would a driver which does this be accepted or is that a complete no-go? Is there any infrastructure in place to help me with this? Am I missing some alternatives?
