18 channels. For instance, page 0 may be located on channel 0, page 1 on channel
19 1, page 2 on channel 2, etc. This is so that writing to memory sequentially
21 done at a much more granular level than a full page.
25 often supports multiple different page sizes. On recent x86_64 systems, 4KiB,
41 * The first device page can be a partial page starting at any 4-byte aligned

44 * If there is more than one device page, the first device page must end on a

46 * The last device page begins on a physical 4KiB page boundary, but is not

71 By far the most common reason is due to page swapping to disk. However, the
73 collapses identical virtual pages onto the same physical page to save memory.
78 POSIX provides the `mlock` call that forces a virtual page of memory to always
79 be backed by a physical page. In effect, this is disabling swapping. This does
