Add the ability to view response codes as well. I dropped the EVENT_CLASS since there is only one event per class. cros_ec_cmd has now been renamed to cros_ec_request_start. Example: $ echo 1 > /sys/kernel/debug/tracing/events/cros_ec/enable $ cat /sys/kernel/debug/tracing/trace 369.416372: cros_ec_request_start: version: 0, command: EC_CMD_USB_PD_POWER_INFO 369.420528: cros_ec_request_done: version: 0, command: EC_CMD_USB_PD_POWER_INFO, ec result: EC_RES_SUCCESS, retval: 16 369.420529: cros_ec_request_start: version: 0, command: EC_CMD_USB_PD_DISCOVERY 369.421383: cros_ec_request_done: version: 0, command: EC_CMD_USB_PD_DISCOVERY, ec result: EC_RES_SUCCESS, retval: 5 Signed-off-by: Raul E Rangel <rrangel@chromium.org> Signed-off-by: Enric Balletbo i Serra <enric.balletbo@collabora.com> |
