Hi,
I run "grep Huge /proc/meminfo" in rhel5.4 .
it shows:
HugePages_Total: 0
HugePages_Free: 0
HugePages_Rsvd: 0
Hugepagesize: 2048 kB
It says hugepagesize is 2M, how can I change the size to 16M?
Any help will be appreciate

I add "hugepagesz=1M hugepages=32" to grub.conf.
The "hugepagesz=16M" doesn't take effect.
The "hugepages=32" take effect.
What type is hardware support that?
Any help will be appreciated.

I really want to know why I cannot change it.
It locked by hardware or os?
If I change and recompile the kernel, may I make it support?
Can I change hugepagesize to bigger or smaller
than 16MB on PPC? Such as 32MB or 4MB.
Any help will be appreciated.

I always want to know which chips and devices
determine the hugepages. Could you tell me?
Any help will be appreciated.

It looks like that hugetlb doesn't work, but it did work before.
Any help will be appreciated.
