Since commit 8eb13bbbac ("ui/gtk: vte: fix sending multiple

If you configure a guest with a serial device and the guest

Currently there is no limit how long the virtual console chardev
backend retries to send remaining characters in the buffer.
Drop the characters after a timeout if the chardev frontend

Hi,
This is v2 of the series [1] that I have posted to introduce some smp parsing
fixes and improvement, much more work has been processed compared to RFC v1.

In the SMP configuration, we should either specify a topology

Currently we directly calculate the omitted cpus based on the already

In the real SMP hardware topology world, it's much more likely that

This patch introduces the vfio-user protocol specification (formerly
known as VFIO-over-socket), which is designed to allow devices to be
emulated outside QEMU, in a separate process. vfio-user reuses the
existing VFIO defines, structs and concepts.

Hi
We are happy to introduce the next stage of the multi-process QEMU project[1].
vfio-user is a protocol that allows a device to be emulated in a separate
process outside of QEMU. It encapsulates the messages sent from QEMU to the
