Title:
Assertion failed with USB pass through with XHCI controller
Status in QEMU:
Fix Committed
Status in qemu package in Debian:
Fix Committed
Bug description:
Starting qemu 2.8.0 with XHCI controller and host device passed
through results in an assertion failure:
qemu-system-x86_64: hw/usb/core.c:623: usb_packet_cleanup: Assertion
`!usb_packet_is_inflight(p)' failed.
Can be reproduced with the following command (passing through a Lenovo
keyboard):
qemu-system-x86_64 -usb -device nec-usb-xhci,id=usb -device usb-
host,vendorid=0x04b3,productid=0x3025,id=hostdev0,bus=usb.0,port=1
If nec-usb-xhci is changed to usb-ehci, qemu tries to boot without
assertion failures.
Can be reproduced with the latest master (commit dbe2b65) and v2.8.0.
Bisected the issue to following commit:
first bad commit: [94b037f2a451b3dc855f9f2c346e5049a361bd55] xhci: use linked
list for transfers
