/* Types of storage, as returned by file_get_storage_info.
STORAGE_DEVICE is a mach device_t (for random access devices)
STORAGE_HURD_FILE is a hurd file_t (as if a file were mapped)
STORAGE_TASK is a task_t (the storage is in the vm of the task)
STORAGE_MEMORY is a memory object port
STORAGE_ZERO is a fixed-size constant source of zeros
STORAGE_INTERLEAVE is a set of other storage types interleaved at a fixed
interval
STORAGE_CONCAT is a set of other storage types concatenated end-to-end
STORAGE_LAYER is a set of storage types, representing the same address
range; all will be written too, and will be read in turn until one
succeeds
STORAGE_REMAP is a layer on top of another store that remaps its blocks
STORAGE_COPY is a memory snapshot of another store
STORAGE_NETWORK means that the file is stored elsewhere on the
network; all the remaining fields contan type-specific information.
STORAGE_OTHER means none of these apply; and should be used when no
meaningful answer can be given
The vectors returned by file_get_storage_info encode each of the above
(note that the first int is always the storage type). There are four:
ports, ints, offsets (off_t), and data (char); each type of store uses the
following entries in each vector:
-type- -ports- -ints- -offsets- -data- -kids-
device DEVICE TY, FL, BS, NR, NL, ML NR * (OFFS, LEN) NL + ML -
file FILE TY, FL, BS, NR, NL, ML NR * (OFFS, LEN) NL + ML -
memory MEMOBJ TY, FL, BS, NR, NL, ML NR * (OFFS, LEN) NL + ML -
task TASK TY, FL, BS, NR, NL, ML NR * (OFFS, LEN) NL + ML -
(the data for the above is a name (incl '\0') and a misc data block)
null - TY, FL SIZE - -
(BS is 1)
ileave - TY, FL, IL, NC - - NC
(BS is the LCM of its children; SIZE is the minimum of theirs * IL)
concat - TY, FL, NC - - NC
(BS is the LCM of its children; SIZE is the sum of theirs)
layer - TY, FL, NC - - NC
(BS is the LCM of its children; SIZE is the minimum of theirs)
remap - TY, FL, NR NR * (OFFS, LEN) - 1
(BS and SIZE are that of the child)
copy - TY, FL, SIZE - DATA -
(DATA is preceded by padding to the next page boundary, and is
SIZE bytes long itself)
For ileave, concat, and layer, the children are encoded following the parent.
The first int must always be TY.
key: TY = type code, FL = flags, BS = block size, NR = num runs,
NL = name len, ML = misc len, NC = num children,
IL = interleave (bytes), SIZE = Size of storage (blocks),
LEN = run length (blocks), OFFS = run offset (blocks),
The NR * (OFFS, LEN) offsets for some of the types is the set of block
ranges in the underlying address space that, concatenated, make up the
contents of the storage -- for instance, doing file_get_storage_info on a
file may return storage of type STORAGE_DEVICE, and the accompanying block
ranges are the set of blocks on the given device that correspond to that
file. Any OFFS == -1 designates a hole in the address range. Note that
the total size (SIZE) for these types is the sum of their LEN's.
The optional NAME returned by some types (if NL != 0) is a type specific
name for the same object referenced by the port also returned. E.g.:
device -- The mach device name
file -- The file name (unreliable, as the root may not be the same)
task -- The pid
Unless it is MACH_PORT_NULL, the port should generally be used instead of
trying to regenerate it from the associated name, which is intended more for
printing messages, etc. */
