Have you ever used system call tracing on sparc? It does not work for
2.6.39 or 4.0; wondering if it has ever worked. I see signs in
arch/sparc/kernel/syscalls.S for example that suggests it should have at
one point.
To clarify I mean through perf. Using the tracing interface via debugfs
I can get the raw_syscall tracepoints, just not through perf.
hmmm... nevermind. It does work on 4.0 (too many perf problems and too
many kernel versions). I'll figure out when it started working.
