Are superpages still supported in OS X. I tried to run the test in xnu (http://www.opensource.apple.com/source/xnu/xnu-2782.40.9/tools/tests/superpa...) but it fails pretty much every test: ➜ /tmp ./testsp Running 14 tests: Test #1 "allocate one page anywhere"...FAILED! (mach_vm_allocate() returned 3) Test #2 "deallocate a page"...FAILED! (skipped deallocation) Test #3 "allocate a SIZE_ANY page anywhere"...FAILED! (mach_vm_allocate() returned 3) Test #4 "allocate one page at a fixed address"...FAILED! (mach_vm_allocate() returned 3) Test #5 "allocate one page at an unaligned fixed address"...OK Test #6 "deallocate sub-page"...FAILED! (mach_vm_allocate() returned 3) Test #7 "allocate already allocated subpage"...FAILED! (mach_vm_allocate() returned 3) Test #8 "wire a page"...FAILED!

Haven’t had a chance to try other OS X versions. -Nathan Hjelm _______________________________________________ Do not post admin requests to the list. They will be ignored.
