[PATCH v2 0/4] vfio-ccw: A couple trace changes

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Here a couple updates to the vfio-ccw traces in the kernel,
based on things I've been using locally.  Perhaps they'll
be useful for future debugging.

Steffen's comments earlier today (thank you!) were simple enough
that here's a quick turnaround on a v2:

v1/RFC -> v2:
 - Convert state/event=%x to %d
 - Use individual fields for cssid/ssid/sch_no, to enable
   filtering by device
 - Add 0x prefix to remaining %x substitution in existing trace

Eric Farman (4):
  vfio-ccw: Refactor how the traces are built
  vfio-ccw: Trace the FSM jumptable
  vfio-ccw: Add a trace for asynchronous requests
  vfio-ccw: Rework the io_fctl trace
