Hi all,
Introduce a -M msi= argument to be able to control MSI-X support independently
from ITS, as part of supporting GICv3 + GICv2m platforms.
Remove vms->its as it's no longer needed after that change.

I’m trying to clarify the current status of ITS under TCG for the virt
machine.(may be a stupid question...)
The virt documentation states: "Note that ITS is not modeled in TCG mode." [1]
Hello,
That’s outdated documentation, ITS emulation was added in Qemu 6.2 to cover the
TCG case.
Was implemented in patchset:

Hi Mohamed,
Thanks for your reply and the pointer to the original 6.2 patchset. I
noticed the commit([PATCH v13 09/28]) updating the virt.rst
documentation and appreciate your effort on that. It really helps clear
up the ITS/TCG confusion I ran into.
Best regards,
Tao
