As the current virtio-mmio only support single irq, so some advanced features such as vhost-net with irqfd are not supported. And the net performance is not the best without vhost-net and irqfd supporting. This patch support virtio-mmio to request multiple irqs like virtio-pci. With this patch and qemu assigning multiple irqs for virtio-mmio device, it's ok to use vhost-net with irqfd on

As mentioned at drivers/base/core.c: /* * NOTE: _Never_ directly free @dev after calling this function, even * if it returned an error! Always use put_device() to give up the * reference initialized in this function instead. */ so we don't free vm_dev until vm_dev.dev.release be called.

This patch add a support for second version of the virtio-mmio device, which follows OASIS "Virtual I/O Device (VIRTIO) Version 1.0" specification. Main changes: 1. The control register symbolic names use the new device/driver nomenclature rather than the old guest/host one. 2. The driver detect the device version (version 1 is the pre-OASIS spec, version 2 is compatible with

This path introduces a new mdev transport for virtio. This is used to use kernel virtio driver to drive the mediated device that is capable of populating virtqueue directly. A new virtio-mdev driver will be registered to the mdev bus, when a new virtio-mdev device is probed, it will register the device with mdev based config ops. This means, unlike the exist hardware transport, this is a software

As mentioned at drivers/base/core.c: /* * NOTE: _Never_ directly free @dev after calling this function, even * if it returned an error! Always use put_device() to give up the * reference initialized in this function instead. */ Normal we do cleanup for @vm_dev by contianer_of(@dev), but in this case we need release @mem resource from @pdev and vm_dev->base. It make
