Subject: [PATCH 00/10] Improving debugging with NMIs
Date: Tue, 20 Dec 2016 04:30:01 +1000 [thread overview]
Message-ID: <20161219183011.28310-1-npiggin@gmail.com> (raw)
Hi,
These patches have been posted a few times before. Since then
I've split them up and tried to simplify the NMI IPI stuff as
much as possible.
I've been testing using David Gibson's QEMU branch ppc-for-2.9,
which implements the required hcall.
Thanks,
Nick
