Hi! I haven’t had to do any modifications to some kernel level pieces that I
worked on for a few years—up until a few days ago.
I started trying to get two-machine debugging going again, but something’s
going wrong… It’s probably something really simple that I’m missing.
I’ve got two macOS 10.13.3 system connected with Thunderbolt Ethernet.
- Manually assigned IP addresses to the respective interfaces, set the debug to
0x144, set the right kdp_match_name
- Triggered a NMI
- Got a connection with lldb, was able to look at variables etc., but when I
‘continue’ the remote machine doesn’t continue.
I thought maybe it was an issue with interrupting a running kernel, so I set
debug to 0x141. Target system pauses during boot for a connection, but when I
try to connect the debugger the target system panics, goes back to waiting for
debugger.
I’ve tried it with SIP enabled and disabled, and with both the release and
development kernels.
Anyone have any ideas what I’m missing here?
Kevin
