A D5level-paging.rst10 space and 64 TiB of physical address space. We are already bumping into
17 It bumps the limits to 128 PiB of virtual address space and 4 PiB of
18 physical address space. This "ought to be enough for anybody" ©.
34 User-space and large virtual address space
36 On x86, 5-level paging enables 56-bit userspace virtual address space.
37 Not all user space is ready to handle wide addresses. It's known that
42 To mitigate this, we are not going to allocate virtual address space
45 But userspace can ask for allocation from full address space by
58 to allocation from 47-bit address space.
