Subject: [PATCH] perf tool: Carve out ctype.h et al

From: Borislav Petkov <[email protected]>

Carve out ctype.* and util.* stuff into tools/lib/util/. We're keeping
those as standalone object files in TOOLS_OBJS and add them to the
targets that need them.

This way we don't do lib archives but single objects only.

Anyway, so you moved hex2u64, ctype interface under tools/lib
and made several Makefile changes to compile tools/lib objects.

Besides that we'd need all those changes separated, who is the
other user of this library? I dont see any in the patch.

Probably will come in a separate patchkit that is dependent on
this, but not strictly related?

Yeah, so roughly speaking, we want to carve out the code which opens and
handles events in perf tool so that we can use it in other tools. In the
particular example with the ras daemon, we want to be able to open a
tracepoint in userspace and read from it.

We're doing this piecewise because perf tool changes too fast and I've
done a full conversion patchset a couple of times already only to
realize that it grows obsolete practically only days after sending it
out. (Btw, for that it is all your fault, of course :-P). Which makes
preparing a full patchset almost impossible.

Does this explanation make sense?

@jirka: I'll try to reproduce your build error.

Thanks.

This is a perfect example why doing this piecewise is the only way to
go! And even that is not easy:

I don't have this line in util/pmu.c:788 so I can't trigger it:

782 bool pmu_have_event(const char *pname, const char *name)
783 {
784 struct perf_pmu *pmu;
785 struct perf_pmu_alias *alias;
786
787 pmu = NULL;
788 while ((pmu = perf_pmu__scan(pmu)) != NULL) {
789 if (strcmp(pname, pmu->name))
790 continue;
791 list_for_each_entry(alias, &pmu->aliases, list)
792 if (!strcmp(alias->name, name))
793 return true;
794 }
795 return false;
796 }

So, I've done the patch ontop of those branches:

Yeah, and albeit it can take time, its how it would be done if this was
touching core kernel code, right? So lets try to do it that way ;-)

I'd say work on tip/perf/core, if it doesn't apply on mine or jolsa's,
we'll fix it up, right Jiri?

We try not to keep too much stuff queued up, so there should be no
problems 99.9% of the time...

Oh sure, I'm not complaining - I'm just discussing our process and how
to optimize it.

Ok, good.

I'll rebase the patch ontop of it tomorrow. Now back to the football
game! :-)

the ras daemon is not in tree yet is it? cant find it..

I think we should librarize only stuff we will share. Whats the plan
about the ras daemon (if I did not overlook it) to be put into tools?

yep, tip/perf/core maybe plus merges from acme/perf/core and jolsa/perf/core
should do it ;-)

Yep, and that functionality depends on generic stuff which we're trying to
export first. :-)

Here's an old version: http://thread.gmane.org/gmane.linux.kernel/1090275

> I think we should librarize only stuff we will share.

You sound just like acme! :-) But yeah, this is what he said at the time
and this is what we want to do - we don't want to do more work than
necessary after all :-)

I'd say no initially, after the kvmtool explosion last time. Which is
still ok I guess.

If it remains out of tree, we will probably have some issues if the
exported pieces change and we'll have to readjust the external code
which depends on it. We'll see.

It builds ok if you do a build when CWD is tools/perf/, but who does
that apart from Jiri? :-)

I'll try to fix this up later today, if you haven't done it by then.

Thanks,

I won't because it is too late here for me to have a functioning brain
still, but don't bother - I'll take care of it tomorrow.

Thanks.

yea, I meant it compiled for me ;-) I haven't reviewd the patch much,
one thing I remember is that it should be separated into smaller changes..
should I wait for new version or review this one?

This is because I created tools/lib/util/util.[ch] for the stuff which
ctype.* needs. I guess I can split it even further if that is easier
for you guys but I don't think the patch is too big to be unparseable -
it is basically moving code to tools/lib/, adding its own Makefile and
making the rest build again... well, almost. :-)
