Subject: [PATCH 0/5] More NMI IPI enablement work
Date: Mon, 18 Sep 2017 18:27:01 +1000 [thread overview]
Message-ID: <20170918082706.6485-1-npiggin@gmail.com> (raw)
Hi,
Here is the NMI IPI enablement for powernv, which requires
supported firmware and hardware:
https://lists.ozlabs.org/pipermail/skiboot/2017-September/009111.html
And some preceeding patches that fix issues I ran into when
testing it.
Thanks,
Nick
