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*. Migration works
with the patch Juan just posted.
There are a few items on my todo list but this works well.
New since last send:
- migrate per-port buffers that are queued up
- in-qemu api for open/close/read/write of ports.
- the read() is a callback that's invoked when complete data
corresponding to one write() request on the guest is available.
- removed comments from virtio_console.c that are no longer relevant.
- address review comments by Juan
TODO:
- 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
Conditions:
* Heavy IO on an hvc port and a non-hvc port causes memory corruption
each time, same place. It could be realted to locking but I doubt
that. This still has to be sorted out
Please review.
Amit
