This is merged from two series now because code especially the test cases have started to depend on one another.
The series are "usb/xhci: TR NOOP, TI HCD device, more qtests" from: https://lore.kernel.org/qemu-devel/20250411080431.207579-1-npig...@gmail.com/ And "usb/msd: Permit relaxed ordering of IN packets" from: https://lore.kernel.org/qemu-devel/20250411080431.207579-1-npig...@gmail.com/ The qtests also depends on the qtest fixes: https://lore.kernel.org/qemu-devel/20250502030446.88310-1-npig...@gmail.com/ This series adds better support qtests support for the xhci controller, adds support for the "TR NOOP" command used by AIX, and adds a new USB controller model from TI that PowerVM and AIX use. It also permits relaxed ordering of USB mass-storage packets from the host, as allowed by the usbmassbulk 1.0 spec, but not usually seen in drivers. AIX drivers do require this ordering. Since previous posting the usb/msd series had some changes that Phil noted. But otherwise the qemu code is mostly unchanged. The qtest code has had some big changes, cleaned up a lot and started adding some USB Mass Storage Device tests including one which verifies the relaxed ordering change. It would be nice if we could plug these into more comprehensive SCSI tests, but so far it mainly just tests the USB MSD protocol.
