My reading of it (see below) is that it's spending a lot of its time on the gadget side interrupt, possibly in the lock on the dwc, but I've not tried debugging around this before, so suggestions welcome. Would it be possible to handle multiple requests per interrupt? From a quick look, it looks like the Qualcomm code should allocate enough bandwidth internally when it sees a superspeed connection? Register debug/etc below Thanks in advance, Dave Kernel 7.3.0-rc6-ish with patches for this laptop.
