In ftrace, add more fields to the cros_ec command event:
- Add size of commands to check if they are properly set.
- Add offset (in case an EC is cascaded being another EC),
to allow proper command output
With:
echo 1 > events/cros_ec/cros_ec_cmd/enable
We now have (on samus)
Invalid command for the sensor stack:
ectool-6942 [002] .... 3082.783116: cros_ec_request_done: version: 3,
offset: 0, command: EC_CMD_MOTION_SENSE_CMD, outsize: 2, insize: 19,
ec result: EC_RES_INVALID_PARAM, retval: 0
Powerd accessing PD EC being the main EC:
powerd-1272 [002] .... 40.644026: cros_ec_request_done: version: 0,
offset: 1, command: EC_CMD_USB_PD_POWER_INFO, outsize: 1, insize: 16,
ec result: EC_RES_SUCCESS, retval: 16
