Hi,
I tested 2.0 with linux-image-3.5-trunk-amd64 3.5.5-1~experimental.1 and
hit a number of issues. The most major issue is:
$ stap -e 'probe kernel.function("do_execve") { printf ("%s", probefunc()); }'
user-space facilities not available without kernel CONFIG_UTRACE or
CONFIG_TRACEPOINTS/CONFIG_ARCH_SUPPORTS_UPROBES/CONFIG_UPROBES
Pass 4: compilation failed. Try again with another '--vp 0001' option.
Debian does not have UTRACE support in its kernels and it seems that due
to a bug systemtap requires it even if you only probe kernel stuff. I
might take a while to get a fix from upstream.
We also need to backport fixes to cope with the fact that
/sys/kernel/debug has 0700 permissions in 3.5.5.
-Timo
