Thanks for you suggestion. But the member hwq->id is an Unsigned integer. if you want to identify SDB mode and MCQ mode,  using "0" is enough, Or how about add string such as below?

ufshcd_command: MCQ: complete_rsp: 1d84000.ufshc: tag: 14, DB: 0x0, size: 32768, IS: 0, LBA: 5979448,opcode: 0x2a (WRITE_10),group_id: 0x0, hqid: 2

Hi Ziqi,

Since 0 is a valid queue ID using 0 to identify the legacy command submission mechanism is ambiguous.

Thanks,

Bart.

OK, let me convert hwq id to int from ftrace side.


Best Regards,
Ziqi
