Hello all, Here is a new iteration of the patch series that implements a transport for guest and host communications. I've tested for compatibility (old qemu & new kernel, new qemu & old kernel, new qemu & new kernel) and it all works fine*. There are a few items on my todo list but this works well. New since last send: - live migration support** - write path in the guest

Hello, This series reworks the ABI to allow port discovery (only) via the control queue and enable multiport again. In addition, it adds support for non-blocking write() support, which means no spinning. This works fine with the recent patches that are on qemu-devel. Also included is removal of hvc_remove() as removing one such console port causes other console ports (registered with hvc) to

Hello, This is the patch that I have for adding support for multiple ports to virtio_console. It's pretty stable in my testing so far and the memory corruption that I had earlier has been resolved in linux-next so I'm proposing this for inclusion. This currently uses device major number 60 from the experimental range; Alan could you please reserve a new major number for virtio_console?

Hey Rusty, These updated patches in the series return -EFAULT on copy_xx_user errors and also move the copy_from_user into fops_write() instead of it being in send_buf. This enables send_buf to just read from kernel buffers, making it simpler. This also allows write()s to write more to the host in one go, removingthe 4k limitation. I do limit the writes to 32k at once to not put too much
