Stanley Chu aa5c697988 scsi: ufs: Add trace event for UIC commands ... Use the ftrace infrastructure to conditionally trace UFS UIC command events. New trace event "ufshcd_uic_command" is created, which samples the following UFS UIC command data: - Device name - Optional identification string - UIC command opcode - UIC command argument1 - UIC command argument2 - UIC command argement3 Usage: echo 1 > /sys/kernel/debug/tracing/events/ufs/enable cat /sys/kernel/debug/tracing/trace_pipe Link: https://lore.kernel.org/r/20200615072235.23042-3-stanley.chu@mediatek.com Acked-by: Avri Altman <avri.altman@wdc.com> Signed-off-by: Stanley Chu <stanley.chu@mediatek.com> Signed-off-by: Martin K.
