Detailed Description

This file contains gm_page_alloc() and gm_page_free().

These GM API functions allow pages to be allocated and freed.

These modules implement a platform-independent page allocation interface, with automatic initialization and finalization for use in the kernel.

In some cases, this file uses platform-specific features to implement page allocation efficiently, but by default this module allocates blocks of pages and keeps a page free list to recycle freed pages, but the module never frees the blocks of pages until all pages have been freed.

gm_page_alloc() returns a ptr to a newly allocated page-aligned buffer of length GM_PAGE_LEN. Return values: ptr  Page-aligned buffer of length GM_PAGE_LEN. See also: gm_page_free Author: Glenn Brown Version: GM_API_VERSION (as defined in gm.h)

GM_ENTRY_POINT void gm_page_free (  void *  ptr  )

gm_page_free() frees the page of memory at ptr previously allocated by gm_page_alloc(). If all pages have been freed, free all of the memory allocated for pages. Parameters: *ptr  (IN) Address of the memory page to be freed. See also: gm_page_alloc Author: Glenn Brown Version: GM_API_VERSION (as defined in gm.h)
