FREE_AREA_INIT_NODES(9) 				    Memory Management in Linux					   FREE_AREA_INIT_NODES(9)

NAME

       free_area_init_nodes - Initialise all pg_data_t and zone data

SYNOPSIS

       void free_area_init_nodes(unsigned long * max_zone_pfn);

ARGUMENTS

       max_zone_pfn
	   an array of max PFNs for each zone

DESCRIPTION

       This will call free_area_init_node for each active node in the system. Using the page ranges provided by add_active_range, the size of each
       zone in each node and their holes is calculated. If the maximum PFN between two adjacent zones match, it is assumed that the zone is empty.
       For example, if arch_max_dma_pfn == arch_max_dma32_pfn, it is assumed that arch_max_dma32_pfn has no pages. It is also assumed that a zone
       starts where the previous one ended. For example, ZONE_DMA32 starts at arch_max_dma_pfn.

NAME

       zprint - show information about kernel zones

SYNOPSIS

       zprint [-w] [-s] [-c] [-h] [name]

DESCRIPTION

       zprint(1)  displays  data  about  Mach zones.  By default, zprint will print out information about all Mach zones.  If the optional name is
       specified, zprint will print information about each zone for which name is a substring of the zone's name.

       zprint interprets the following options:

       -w      For each zone, zprint calculates how much space is allocated but not currently in use, the space wasted by the zone.

       -s      zprint sorts the zones, showing the wasting the most memory first.

       -c      (Default) zprint prints zone info in columns. Long zone names are truncated with '$', and spaces are replaced with  '.',  to  allow
	       for sorting by column.  Pageable and collectible zones are shown with 'P' and 'C' on the far right. Zones with preposterously large
	       maximum sizes are shown with '----' in the max size and max num elts fields.

       -h      (Default) Shows headings for the columns printed with the -c option.  It may be useful to override this option when sorting by col-
	       umn.

       Any  option  (including	default options) can be overridden by specifying the option in upper-case; for example, -C overrides the (default)
       option -c.
