Subject: how to avoid allocating or freeze MOVABLE memory in userspace
Date: Fri, 13 Apr 2012 22:35:39 +0800	[thread overview]
Message-ID: <CAN1soZzEuhQQYf7fNqOeMYT3Z-8VMix+1ihD77Bjtf+Do3x3DA@mail.gmail.com> (raw)

Hi all,

I have one question on memory migration. As we know, malloc() from
user app will allocate MIGRATE_MOVABLE pages. But if we want to use
this memory as DMA usage, we can't accept MIGRATE_MOVABLE type. Could
we change its behavior before DMA working?

Thanks
Haojian
