Introduction
|
||||
------------
|
||||
|
||||
_`.intro`: The generic virtual mapping module implements the virtual
|
||||
mapping interface (see design.mps.vm_) using only services provided by
|
||||
the Standard C Library (standard.ansic.7).
|
||||
|
||||
.. _design.mps.vm: vm
|
||||
|
||||
_`.readership`: Any MPS developer.
|
||||
|
||||
|
||||
Design
|
||||
------
|
||||
|
||||
_`.page.size`: The generic VM uses a fake page size, given by the
|
||||
constant ``VMAN_PAGE_SIZE`` in ``config.h``.
|
||||
|
||||
_`.reserve`: Address space is "reserved" by calling ``malloc()``.
|
||||
|
||||
_`.release`: Address space is "released" by calling ``free()``.
|
||||
|
||||
_`.map`: Mapping (and unmapping) fills the mapped region with copies
|
||||
of ``VMJunkBYTE`` to emulate the erasure of freshly mapped pages by
|
||||
virtual memory systems.
