Subject: no hugepage with UIO poll-mode driver
Date: Wed, 25 Nov 2015 14:45:44 +0900	[thread overview]
Message-ID: <56554B08.3040400@ndsl.kaist.edu> (raw)

Hello,

I'm trying to create rte mempool with my own memory scheme (shared virtual memory between CPU & GPU) other than using hugepage. I'm using IGB UIO module with Ethernet 10G 2P X520 Adapter NIC.

I first tried to disable hugepage by inserting "--no-huge" option, but it gave an error at rte_mempool_create function. Then I found in rte_eal.h file that said "no-huge mode cannot be used with UIO poll-mode drivers like igb/ixgbe".

Is there a way to switch DPDK code to not use hugepage with ixgbe driver or is it not possible to do so?

Thank you,
Younghwan
