pagesize - Print supported system page sizes


pagesize [options]


The pagesize utility prints the page sizes of a page of memory in bytes, as returned by getpagesizes(3). This is useful when creating portable shell scripts, configuring huge page pools with hugeadm or launching applications to use huge pages with hugectl.

If no parameters are specified, pagesize prints the system base page size as returned by getpagesize(). The following parameters affect what other pagesizes are displayed.

--huge-only, -H

Display all huge pages supported by the system as returned by gethugepagesizes().

--all, -a

Display all page sizes supported by the system.
