Is there a system command or kernel call that returns the physical address corresponding to the logical address allocated by malloc? In my code, I first do a malloc for all of the free physical ram followed by mlock. Because I'm only allocating from the free physical ram pool, all allocated memory resides in ram (which it must for a memory test application). However, the start address returned by malloc is a local address which I can't figure out how to map to the physical DIMM. If I run two instances of the program at the same time and allocate half the free ram to each instance, both instances have the same local start address. How does one figure out the physical address corresponding to these local addresses returned by malloc? Also, I'm under the impression that the memory manager doesn't run in single-user mode. Does that mean that these local addresses are really physical addresses in single-user mode? This email sent to site_archiver@lists.apple.com
