similar to: [RFC] kvm tools: Add support for virtio-mmio

From: Asias He <asias.hejun at gmail.com> This patch is based on Sasha's 'kvm tools: Add support for virtio-mmio' patch. ioeventfds support is added which was missing in the previous one. VQ size/align is still not supported. It adds support for the new virtio-mmio transport layer added in 3.2-rc1. The purpose of this new layer is to allow virtio to work on systems which

This is a first go at adding support for the modern (based on the 1.0 virtio spec) virtio-pci implementation. kvmtool makes it simple to add additional transports such as this because of it's layering, so we are able to add it as a 3rd (after legacy virtio-pci and virtio-mmio) transport layer, and still allow users to choose to use either the legacy or the modern implementations (but setting

This patch adds an option to instantiate guest virtio-mmio devices basing on a kernel command line (or module) parameter, for example: virtio_mmio.devices=0x100 at 0x100b0000:48 Signed-off-by: Pawel Moll <pawel.moll at arm.com> --- Hi Rusty, As the param changes are in now, could you queue this long-time-forgotten patch for 3.5? Cheers! Pawel PS. Congratulations once again and see

This is the initial proposal for a paravirtualized IOMMU device using virtio transport. It contains a description of the device, a Linux driver, and a toy implementation in kvmtool. With this prototype, you can translate DMA to guest memory from emulated (virtio), or passed-through (VFIO) devices. In its simplest form, implemented here, the device handles map/unmap requests from the guest. Future
