[Qemu-devel] USB3 misbehavior with cpu hotplug and certain timer settings

[Andrey Korolyov]

Hello,

there is an issue which is not a bug itself (as anyone who plays with
Windows should be advised to use hypervclock timers), but it can
indicate some issue with interrupt handling.

Assume two launch strings (attached), and execution of

'{"execute":"cpu-add","arguments":{"id":1}}'

the "regular" case offers only RTC timer and HV offers all
enlightenment features. With Windows2012R2, my usb tablet is going
unresponsive after CPU hotplug event (cursor disappears from screen as
well) for non-hv timer setting, where hv-enabled instance works just
well.
