This is useful to see which EC commands are being executed and when.
To enable:
echo 1 > /sys/kernel/debug/tracing/events/cros_ec/enable
Example:
cros_ec_cmd: version: 0, command: EC_CMD_GET_VERSION
cros_ec_cmd: version: 0, command: EC_CMD_GET_PROTOCOL_INFO
cros_ec_cmd: version: 1, command: EC_CMD_GET_CMD_VERSIONS
cros_ec_cmd: version: 1, command: EC_CMD_USB_PD_CONTROL
The list of current commands is generated using the following script:
sed -n 's/^#define \(EC_CMD_[[:alnum:]_]*\)\s.*/\tTRACE_SYMBOL(\1),\\/p' include/linux/mfd/cros_ec_commands.h
