Hugepages OrangePi One H3

[jeyjey]

Hi. I have an issue configuring the board: no hugepage configured. I installed the command line Ubuntu. No I am in command line via SSH. Everything is ok. With a NanoPi Fire3, OrangePi Pc2 and an OrangePi Zero H5 I had not this issue. The folder /sys/kernel/mm/hugepages does not exist; the folder /proc/sys/vm has not the value or file that tells how mutch is the hugepages amount.

Hugepages (at least transparent hugepages) are not supported on a 32-bit ARM CPU without a MMU, and on ARM in general with the 3.4.x kernel.

What is the process for enabling hugepages on NanoPi Fire3?

Build or use a kernel from a nightly repository and it should work.

Are hugepages enabled by default for the nightly repository images?

 

I do seem to have gotten it to work with this command:

sudo sysctl -w vm.nr_hugepages=128

 

When I run this, hugepages seem to be on:

cat /proc/meminfo | grep Huge
