This would probably be equivalent to a fixed mapping from VM to physical memory. OK, there's no limit to the amount of memory that you can wire in this manner. I heard that OS-X Panther was in some ways a 64-bit OS. In other words, I thought tasks could execute 64-bit addressing load and store machine instructions. Maybe I am mistaken. Also, I maybe mistakenly thought that you could compile a C/C++ program in a way such that you could have 64-bit pointers that are dereferenced. On current versions of Mac OS X all processes have a 32-bit address space and run in 32-bit mode. sizeof(char *) is always 4. If these things are not available, does anyone one have an idea of when they will become available in the future?
