Hello,
I need my driver kext(32-bit, ppc and i386) to support 64-bit application.
I think there is no 64-bit kext, right?
I need memory map in my kext to the memory address from the user space application.
When the address is 64-bit, I only find one API IOMemoryDescriptor::withAddressRange can handle this.
But with this API, I can only build the kext with 10.5 SDK. That means the kext can only run on 10.5. It can not run on 10.4.
Does any other method exist to handle this problem?
Thanks!
