Re: Any way to access huge pages ?

[Wim Coekaerts <wim.coekaerts@oracle.com>]

well thats where you have hugetlbfs
and you mmap a file in /dev/hugetlbfs or whever it goes
works fine

or shmfs but the its not large pages I guess, unless you have the
bigpages feature in the vendor versions. like bigpages in rhas21 can be
for shmfs.
