2.17.1
From: Bean Huo <[email protected]>
Transaction Specific Fields (TSF) in the UPIU package could be CDB
(SCSI/UFS Command Descriptor Block), OSF (Opcode Specific Field), and
TM I/O parameter (Task Management Input/Output Parameter). But, currently,
we take all of these as CDB in the UPIU trace. Thus makes user confuse
among CDB, OSF, and TM message. So fix it with this patch.

2.17.1
From: Bean Huo <[email protected]>
__print_symbolic() is designed for exporting the print formatting table
to userspace and allows parsing tool, such as trace-cmd and perf, to analyze
trace log according to this print formatting table, meanwhile, by using
__print_symbolic()s, save space in the trace ring buffer.
original print format:
print fmt: "%s: %s: HDR:%s, CDB:%s", __get_str(str), __get_str(dev_name),
__print_hex(REC->hdr, sizeof(REC->hdr)),
__print_hex(REC->tsf, sizeof(REC->tsf))
after this change:
print fmt: "%s: %s: HDR:%s, CDB:%s",
print_symbolic(REC->str_t, {0, "send"},
{1, "complete"},
{2, "dev_complete"},
{3, "query_send"},
{4, "query_complete"},
{5, "query_complete_err"},
{6, "tm_send"},
{7, "tm_complete"},
{8, "tm_complete_err"}),
__get_str(dev_name), __print_hex(REC->hdr, sizeof(REC->hdr)),
__print_hex(REC->tsf, sizeof(REC->tsf))
Note: This patch just converts current __get_str(str) to __print_symbolic(),
the original tracing log will not be affected by this change, so it
doesn't break what current parsers expect.

2.17.1
From: Bean Huo <[email protected]>
Current EM macro definition, we use stringize operator '#', which turns
the argument it precedes into a quoted string. Thus requires the symbol
of __print_symbolic() should be the string corresponding to the name of
the enum.
However, we have other cases, the symbol and enum name are not the same,
we can redefine EM/EMe, but there will introduce some redundant codes.
This patch is to remove this restriction, let others reuse the current
EM/EMe definition.

While this version doesn't have the copy/paste typo,
I fail to see value in defining EMe as a trailing comma
in an array declaration isn't meaningful and doesn't emit
any error or warning.
Maybe all the uses of EMe can be converted to EM and the
macro definitions removed.

Bean Hi,
I support this series.
I think it is a good idea to print the response on complete,
But you need to change the prefix strings, otherwise you are breaking the current parsers.
Say that you have a trace log, generated sometime during 2020 using the current upiu trace.
It would look something like:
"send" <request upiu>
"complete" <request upiu>
And another log generated sometime during 2021 after your change is merged:
"send" <request upiu>
"complete" < ****response upiu ****>
The current parser won't be able to differentiate between those logs.
Just change the prefix strings to be "send_req" and "complete_rsp", or something,
so the parsing tools that support the new format will be able to differentiate it from the old one.
Also, once the parser can differentiate the new format from the old,
whatever follows its fine: cdb / osf / tsf or whatever makes sense to you.
Thanks,
Avri

Avri,
I still don't understand, this change doesn't break you current parser.
if you still trace "send", "complete", "CDB", "query_send/complte",
they are still there, doesn't change. I suggest you just run on your
system. see if there is conflict.
Regarding your suggestion:
This is not problem now, we just change this definition.
do you mean just "send" and "complete" or all?
#define
UFS_CMD_TRACE_STRINGS \
EM(UFS_CMD_SEND, "send_req") \
EM(UFS_CMD_COMP, "complete_rsp") \
below also need add "req" and "rsp"?
EM(UFS_DEV_COMP, "dev_complete_rsp") \
EM(UFS_QUERY_SEND, "query_send") \
EM(UFS_QUERY_COMP, "query_complete") \
EM(UFS_QUERY_ERR, "query_complete_err") \
EM(UFS_TM_SEND, "tm_send") \
EM(UFS_TM_COMP, "tm_complete") \
EM(UFS_TM_ERR, "tm_complete_err")

Hi Joe
I removed EMe, but there is this error:
./include/trace/trace_events.h:300:18: error: initializer element is
not constant
{ symbol_array, { -1, NULL }}; \
./include/trace/trace_events.h:300:18: error: expected expression
before ‘,’ token
{ symbol_array, { -1, NULL }}; \
did you choose kernel trace and event trace before compiling?
Thanks,
Bean

If you make EM a parameter to UFS_LINK_STATES then the caller
can pass in the name of a #define that does the required expansion.
The caller can also add in any required terminator after the last entry.
For an enum (which doesn't want a , at the end) just add a dummy entry.
You often want a constant for the number of items anyway.

Currently, in the query completion trace print, since we use
hba->lrb[tag].ucd_req_ptr and didn't differentiate UPIU between
request and response, thus header and transaction-specific field
in UPIU printed by query trace are identical. This is not very
practical. As below:
query_send: HDR:16 00 00 0e 00 81 00 00 00 00 00 00, CDB:06 0e 03 00 00 00 00 00 00 00 00 00 00 00 00 00
query_complete: HDR:16 00 00 0e 00 81 00 00 00 00 00 00, CDB:06 0e 03 00 00 00 00 00 00 00 00 00 00 00 00 00
For the failure analysis, we want to understand the real response
reported by the UFS device, however, the current query trace tells
us nothing. After this patch, the query trace on the query_send, and
the above a pair of query_send and query_complete will be:
query_send: HDR:16 00 00 0e 00 81 00 00 00 00 00 00, CDB:06 0e 03 00 00 00 00 00 00 00 00 00 00 00 00 00
ufshcd_upiu: HDR:36 00 00 0e 00 81 00 00 00 00 00 00, CDB:06 0e 03 00 00 00 00 00 00 00 00 01 00 00 00 00

This is currently the way its done in multiple other places. When creating
the "EMe" trick, I've thought about it, but then realized it would make the
other locations look strange without the expected comma, and decided that
EMe() would be the best solution, as it's only strange in where it's added,
and not where its used.
$ git grep -l EMe include/trace/ |wc -l
11
It's already used in 11 other files, let's not muck with it now.

Hi Avri
Before sending next version, double confirm with your. I think you
just need change:
"send" to "send_req"
"complete" to "complete_rsp"
