Lines Matching full:address

9 Original x86-64 was limited by 4-level paing to 256 TiB of virtual address
10 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.
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
46 specifying hint address (with or without MAP_FIXED) above 47-bits.
48 If hint address set above 47-bit, but MAP_FIXED is not specified, we try
49 to look for unmapped area by specified address. If it's already
50 occupied, we look for unmapped area in *full* address space, rather than
53 A high hint address would only affect the allocation in question, but not
56 Specifying high hint address on older kernel or on machine without 5-level
58 to allocation from 47-bit address space.
61 about large address space without manually tracking allocated virtual
62 address space.
