I hadn't realized that there was now a public API in 10.6. execv of kextload still works, so I had no need to update my pre-10.6 code ;-). --Amanda _______________________________________________ Do not post admin requests to the list.

I personally have been working on the beginning of a port of XNU to ARM, however it is just in the planning stages (working on bootloader + support tools although I am not planning on being compatible with any IOS code).

Execv() of kextload is not likely to be appreciably faster than calling an SPI directly--most of the time is I/O time scanning and patching/linking the kext bundle, last I checked. And since it's not a public API, I can't think of any reason for the latter… That said, reading the source for kextload, kextstat, etc. can be very informative. Doing so is what convinced me I should just call out to them :-). --Amanda _______________________________________________ Do not post admin requests to the list. They will be ignored.
