The 9p-virtio transport does zero copy on things larger than 1024 bytes in size. It accomplishes this by returning the physical addresses of pages to the virtio-pci device. At present, the translation is usually a bit shift. However, that approach produces an invalid page address when we read/write to vm...

On device hot-unplug, 9p/virtio currently will kfree channel while it might still be in use. Of course, it might stay used forever, so it's an extremely ugly hack, but it seems better than use-after-free that we have now. Signed-off-by: Michael S.

I've run into an issue with 9p file sharing that I suspect is a bug. I'm running some Debian ARM VMs (armhf Ubuntu guests on an aarch64 Debian stretch host in case that matters). I'm using direct kernel boot, so I'm also using 9p host file sharing so that kernel updates from within the guest would work. However, I...

Some virtio device drivers (9p) need to translate high virtual addresses to physical addresses, which are inserted into the virtqueue for processing by userspace. This patch exports the kmap_to_page symbol, so that the affected drivers can be compiled as modules. Signed-off-by: Will Deacon <will.deacon at arm.com> --- m...

Add basic documentation for virtio-9p. I can expand more on device operation, but I don't think there's anything significant enough for the spec to be mentioned there. Please let me know if I'm wrong. Signed-off-by: Sasha Levin <sasha.levin at oracle.com> --- virtio-spec.lyx | 206 +++++++++++++++++++++++++++++++++++...

On device shutdown/removal, virtio drivers need to trigger a reset on the device; if this is neglected, the virtio core will complain about non-zero device status. This patch resets the status when the 9p virtio driver is removed from the system by calling vdev->config->reset on the virtio_device to send a reset to the host virtio device.
