Subject: [dpdk-dev] DPDK hugepages are movable?
Date: Mon, 23 Nov 2020 09:01:14 -0800
Message-ID: <20201123090114.75ea1bb0@hermes.local> (raw)

There is a problem being discussed in the Linux memory management list
that maybe of interest to DPDK developers. The DPDK/ VFIO assumes that
it can do DMA from hugepaged memory because it is pinned. But in reality
the hugepages are still in ZONE_MOVABLE.
