Hello all,
Here is a new iteration of the patch series that implements a
transport for guest and host communications.
The code has been updated to reuse the virtio-console device instead
of creating a new virtio-serial device.
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:
- connect/disconnect notifications on connections to ports
TODO:
- Look at converting to a tty interface instead of the current char
interface
- Migration: save the extra state that's necessary
- Convert all config writes to little endian in qemu / convert from
little endian to host endian in guest
- Address a few FIXMEs spread in the code
- Introduce a watermark to stop a rogue host process flooding guest
with data
- Make connect/disconnect work for guest
Please review.
Amit
