Subject: [PATCH v2 0/7] selftsts/ftrace: Add requires list for each test case
Hi,
Here is the 2nd version of the series of "requires:" list for
simplifying and unifying requirement checks for each test case.
The previous version is here.
https://lkml.kernel.org/r/159102252279.31199.12855129586058455119.stgit@devnote2
I've fixed some trival mistakes and add Tom's reviewed-by
in this version.
Currently, we have many similar requirement checker to find
unconfigured or unsupported (in older kernels) feature in
each test case. I think it is a good time to unify those similar
checks.
As same as "description:" or "flags:" line, this series introduces
new "requires:" line, and convert current checking code intor the
"requires:" line.
This requires line gives some good effects, not only simplyfies
the code, but also unifies the reason message, and because it checks
the requirements before running the testc ase, it skips unneeded
ftrace initialization.
The requires line supports following checks
- tracefs interface check: Check whether the given file or directory
in the tracefs. (No suffix) [3/7],[4/7],[5/7]
- available tracer check: Check whether the given tracer is available
(":tracer" suffix) [6/7]
- README feature check: Check whether the given string is in the
README (":README" suffix) [7/7]
This series also includes the description line fix and
unresolved -> unsupported change ([1/7] and [2/7]).
Note: Since the requires line returns UNSUPPORTED error,
the requirements must be one of ftrace feature, but not the
user-space environmental requirement. If there is some issue
in user-space (e.g. lack of the command, modules, etc) it must
report UNRESOLVED error.
Since this series depends on following 2 commits,
commit 619ee76f5c9f ("selftests/ftrace: Return unsupported if no
error_log file") on Shuah's Kselftest tree
commit bea24f766efc ("selftests/ftrace: Distinguish between hist
and synthetic event checks") on Steven's Tracing tree
This can be applied on the tree which merged both of them.
Also, you can get the series from the following.
git://git.kernel.org/pub/scm/linux/kernel/git/mhiramat/linux.git ftracetest-requires-v2
Thank you,
