Subject: [dpdk-users] 0MB available on socket when running pktgen-dpdk
Date: Wed, 28 Jun 2017 17:03:11 +0000 [thread overview]
Message-ID: <942AD08E4186F644A54168E4F84117C9317DB2@SAUSMAILMBX1.ad.tri.sbc.com> (raw)
When I run pktgen-dpdk I always get the error that there are 0MB available (no
matter how much I request). However, if I run testpmd, then it seems to run
without complaint. Does anybody know what's going on?
P.S. Why does /proc/meminfo always report that there are 0 hugepages free after
I do anything with DPDK? Does it not clean up afterward and free them? If I rm
/mnt/huge/* then /proc/meminfo reports that the hugepages were freed, but it
seems like I shouldn't have to manually do that.
P.P.S. If /proc/meminfo reports that there are 0 hugepages free, then why does
testpmd work? It appears to be using them, since they are no longer free after
running testpmd.
