I am adding a multithreaded class to SoftRAID kext and want to allocate one thread per logical CPU (i.e. 2 threads per core if HyperThreading is present). How can I determine the number of logical CPUs present? I know I can search through the IORegistry for objects of type IOACPIPlatformDevice and look for the one with the highest processor-number value and then add 1 to that value. I just thought there might be some easier way. Thanks, Tim Standing SoftRAID LLC _______________________________________________ Do not post admin requests to the list. They will be ignored.
