--- Comment #1 from William Cohen <wcohen at redhat dot com> ---
I added the support for aarch64 to systemtap. It significant work to add
architecture support for a new platform.  We welcome outside patches to sup=
port
new architectures, but it is unlikely that we are going to develop one for
SPARC.  One could use the changes in systemtap for aarch64 as suggestions of
where changes need to be made to support a new architecture:

https://sourceware.org/git/?p=3Dsystemtap.git&a=3Dsearch&h=3DHEAD&st=3Dcomm=
it&s=3Daarch64

In the kernels sparc has HAVE_KPROBES in linux/arch/sparc/Kconfig, so kprob=
es
are implemented.  However, I don't know have tested that is. I found some
issues with the aarch64 implementation of kprobes when working on the syste=
mtap
aarch64 support.
