Hello List,
the answer to this is probably easy to find in the right place, but is there a memory allocation routine that is interrupt safe? From the documentation for IOMalloc it is clear that it is not, so is there a function that is?

Or would I have to allocate all my memory prior to going into interrupt context?


You should make all attempts to allocate memory before hand.
