Detect whether libtraceevent is installed and if so build against
it. If not installed, warn and build a subset of perf that works
without libtraceevent. With nothing using the now out-of-date
tools/lib/traceevent remove it.
Discussed on LKML here:
https://lore.kernel.org/lkml/CAP-5=fWxAjEia-Qbm0RVzKOxyiod8rUOBieqaGK=DtQboDe3Qw@mail.gmail.com/
Builds upon:
https://lore.kernel.org/lkml/20221116224631.207631-1-irogers@google.com/
Based on discussion of the v1 patch set:
https://lore.kernel.org/lkml/20221117224952.358639-1-irogers@google.com/
v2 conditionally compiles a subset of perf that doesn't require
libtraceevent to avoid having to have libtraceevent installed on a
system.
The changes build upon the fix in:

Ian Rogers (4):
perf util: Make header guard consistent with tool
perf util: Add host_is_bigendian to util.h
perf build: Use libtraceevent from the system

If libtraceevent isn't installed or NO_LIBTRACEEVENT=1 is passed to the build, don't compile in libtraceevent and libtracefs support. This also disables CONFIG_TRACE that controls "perf trace". CONFIG_TRACEEVENT is used to control enablement in Build/Makefiles, HAVE_LIBTRACEEVENT is used in C code. Without HAVE_LIBTRACEEVENT tracepoints are disabled and as such the commands kmem, kwork, lock, sched and timechart are removed. The majority of commands continue to work including "perf test".

Maybe we can have a different approach. I guess the trace data access is isolated then we can make dummy interfaces when there's no libtraceevent. This way we don't need to touch every command and let it fail when it's asked. The motivation is that we should be able to run the sub-commands as much as possible. In fact, we could run 'record' part only on the target machine and pass the data to the host for analysis with a full-fledged perf. Also some commands like 'perf lock contention' can run with or without libtraceevent (using BPF only). Thanks, Namhyung ^ permalink raw reply [flat|nested] 17+ messages in thread

The issue here is that perf lock contention will use evsel__new_tp and internally that uses libtraceevent. As such it is removed without HAVE_LIBTRACEEVENT. Without the evsel there's not much perf lock contention can do, so rather than litter the code with HAVE_LIBTRACEEVENT and for it to be broken, I made the choice just to remove it from the no libtraceevent build for now. I think it is worth pursuing these patches in the shape they are in so that we can land the removal of tools/lib/traceevent and ensure the migration away from an out-of-date version of that library.

I don't think it needs evsel__new_tp() when BPF is used.

Yeah, I agree that we should remove the stale libtraceevent but I'd like to do it with minimal changes in the perf code base. Let me take a look at this.

I think this will remain true even with a new evsel__newtp function that isn't dependent on libtraceevent. I also think adding such things is best kept out of this patch which is trying to do the minimal (only 312 lines of addition) to have a build without libtraceevent. Given we expect builds to use libtraceevent and we should build off of this patch, I think we should look to land it for 6.2. Thanks, Ian ^ permalink raw reply [flat|nested] 17+ messages in thread

So I took a quick look and it seems not quite easy to isolate libtraceevent accesses from perf trace, dynamic sort keys and other places. That would need some amount of work. Now I think that we may apply this first and then work on enabling more functionalities without libtraceevent gradually. Also I think it'd be a major change for regular users if there's no libtraceevent installed in their system. Maybe we could add a warning during the build?
