Hi all,
I'm debugging a performance issue on a PPC OpenWrt distribution, running
linux 3.3.8, and I've trying to debug it with a build of the lttng software
off the master branches. I made a slight modification to get a
cross-compile working (renaming compat/{fcntl,poll,uuid}.h to prevent
recursive inclusions), and that source works fine for an x86 target on
kernel 3.4.46.
I've got it capturing syscalls, but nothing else. All the drivers load
OK. I have every tracer and probe I can find turned on:
CONFIG_KPROBES=y
CONFIG_KRETPROBES=y
CONFIG_HAVE_KPROBES=y
CONFIG_HAVE_KRETPROBES=y
CONFIG_NET_TCPPROBE=m
CONFIG_TRACEPOINTS=y
CONFIG_HAVE_SYSCALL_TRACEPOINTS=y
CONFIG_KALLSYMS=y
CONFIG_KALLSYMS_ALL=y
Can anybody give me some hints as to where to look?
