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 drivers/s390/cio/Makefile | 4 +- drivers/s390/cio/vfio_ccw_cp.h | 1 + drivers/s390/cio/vfio_ccw_fsm.c | 11 +++-- drivers/s390/cio/vfio_ccw_private.h | 1 + drivers/s390/cio/vfio_ccw_trace.c | 14 ++++++ drivers/s390/cio/vfio_ccw_trace.h | 76 ++++++++++++++++++++++++++--- 6 files changed, 93 insertions(+), 14 deletions(-) create mode 100644 drivers/s390/cio/vfio_ccw_trace.c -- 2.17.1
