Subject: Huge ring allocation
Date: Thu, 25 Aug 2016 09:05:47 +0300 [thread overview]
Message-ID: <9114674.mxuR5Pefat@polaris> (raw)
Hello,
I have a DPDK process that creates pktmbuf pool with 2_000_000 objects
In CentOS 6.x x86-64, ring size of this pool is 16MB
8 2MB hugepages required to hold such ring.
In some cases, hugepages are too fragmented and there are no 8 contiguous hugepages for the ring.
As the result, the process has enough hugepages memory, but ring allocation fails.
I use a workaround for these cases and create a ring with standard OS allocation routines.
Is there another way I could use unclaimed dpdk hugepages for that allocation ?
Regards,
Gregory
