nvme: fix nvme_setup_command metadata trace event

2021-07-21T07:55:44+00:00

The metadata address is set after the trace event, so the trace is not capturing anything useful. Rather than logging the memory address, it's useful to know if the command carries a metadata payload, so change the trace event to log that true/false state instead.

nvme-trace: print result and status in hex format

2019-06-21T09:12:37+00:00

The "result" field is in 64bit to be printed out which means it could be like: nvme_complete_rq: nvme0: qid=0, cmdid=0, res=18446612684158962624, etries=0, flags=0x0, status=0 Switch both the result and status field to be printed in hexadecimal format to be easier to read.

nvme-trace: support for fabrics commands in host-side

2019-06-21T09:12:22+00:00

This patch introduces fabrics commands tracing feature from host-side. This patch does not include any changes for the previous host-side tracing, but just add fabrics commands parsing in cmd=() format. Signed-off-by: Minwoo Im [hch: fixed some whitespace damage] Signed-off-by: Christoph Hellwig

nvme-trace: move opcode symbol print to nvme.h

2019-06-21T09:12:19+00:00

The following patches are going to provide the target-side trace which might need these kind of macros. It would be great if it can be shared between host and target side both. Signed-off-by: Minwoo Im Signed-off-by: Christoph Hellwig

nvme: trace all async notice events

2019-05-14T15:19:47+00:00

This patch removes the tracing of the NVMe Async events out of the switch so that it can trace all the events including the ones which are not handled in the nvme_handle_aen_notice(). The events which are not handled in the nvme_handle_aen_notice() such as NVME_AER_NOTICE_DISC_CHANGED corresponding event identifier needs to be added in the drivers/nvme/host/trace.h so that it can stringify the AER .

2019-03-13T18:05:39+00:00
