Title:
xHCI Port Status Change Event at port powered
Status in QEMU:
Invalid
Bug description:
Per section 4.19.3 of the xHCI version 1.0 specification, when the
Port Power bit transitions from 0 to 1, if there is a connection on
that port, a Port Status Change Event should be issued.
Currently, when the port is powered, this event is not being issued.
I don't know the QEMU code base well enough to submit a patch, but I
believe that when the port is powered, check to see if there is a
connection (hence, setting the CCS and CSC bits), and then a call to:
xhci_port_notify(port, PORTSC_PLC);
will suffice.
Thank you,
Ben
