Thanks for reply I am looking memory compaction support on arm. compaction which is hugtlb dependent. does hugetlb supports arm if not then why Thanks, Solmac On Sun, Mar 27, 2011 at 9:30 PM, <kernelnewbies-request@kernelnewbies.org>wrote:

I am having the following query regarding Huge pages and hugetlbfs. 1-> How Hugetlbfs is dependent on hardware ?

Hugetlbfs needs two things: 1) the hardware supports large pages, simultaneously running with normal sized pages 2) someone wrote the hugetlbfs architecture dependent code for that hardware

...

2-> Huge pages which is architecture dependent and ARM arm architecture supports Tiny, small and large pages will it support hugetlbfs if not then why ?

That I don't know. Does ARM support running with normal and large pages simultaneously?
