Hi Doug,
Very good idea here, I used to add some local patch and with USB
analyzer to debug this part of code, and we can use more tools with
your patch now, I can try kernelshark next time.
Do you consider to add tracing for qtd? Then we can track the whole
lift cycle of urb in dwc2 dri
In preparation for future changes to the scheduler let's add some
tracing that makes it easy for us to see what's happening. By default
this tracing will be off.
By changing "core.h" you can easily trace to ftrace, the console, or
nowhere.
