Subject: [PATCH 0/3] virtio DMA API core stuff
Date: Tue, 27 Oct 2015 18:17:07 -0700 [thread overview]
Message-ID: <cover.1445994839.git.luto@kernel.org> (raw)
This switches virtio to use the DMA API unconditionally. I'm sure
it breaks things, but it seems to work on x86 using virtio-pci, with
and without Xen, and using both the modern 1.0 variant and the
legacy variant.
Andy Lutomirski (3):
virtio_net: Stop doing DMA from the stack
virtio_ring: Support DMA APIs
virtio_pci: Use the DMA API
