Subject: [PATCH 0/8] Virtio-over-PCIe on non-MIC
Date: Wed, 16 Jan 2019 17:32:45 +0100 [thread overview]
Message-ID: <20190116163253.23780-1-vincent.whitchurch@axis.com> (raw)
The Virtio-over-PCIe framework living under drivers/misc/mic/vop implements a
generic framework to use virtio between two Linux systems, given shared memory
and a couple of interrupts. It does not actually require the Intel MIC
hardware, x86-64, or even PCIe for that matter. This patch series makes it
buildable on more systems and adds a loopback driver to test it without special
hardware.
Note that I don't have access to Intel MIC hardware so some testing of the
patchset (especially the patch "vop: Use consistent DMA") on that platform
would be appreciated, to ensure that the series does not break anything there.
Vincent Whitchurch (8):
vop: Use %z for size_t
vop: Cast pointers to uintptr_t
vop: Add definition of readq/writeq if missing
vop: Allow building on more systems
vop: vringh: Do not crash if no DMA channel
vop: Fix handling of >32 feature bits
vop: Use consistent DMA
vop: Add loopback
