Add tracepoints to the driver via a new file e1000e_trace.h and some new trace calls added in interesting places in the driver. Add some tracing for s0ix flows to help in a debug of shared resources with the CSME firmware. The idea here is that tracepoints have such low performance cost when disabled that we can leave these in the upstream driver. Performance not affected, and this can be very useful for debugging and adding new trace events to paths in the future. Usage: echo "e1000e_trace:*" > /sys/kernel/debug/tracing/set_event echo 1 > /sys/kernel/debug/tracing/events/e1000e_trace/enable Signed-off-by: Sasha Neftin <sasha.neftin@intel.com> Tested-by: Naama Meir <naamax.meir@linux.intel.com> Signed-off-by: Tony Nguyen <anthony.l.nguyen@intel.com> |
