AFAIK kgdb (remote debug) is not supported: http://openbsd-archive.7691.n7.nabble.com/on-line-kernel- debugging-tt335833.html#a341551 You can debug running kernel but functionality is limited.

Remote kernel debugging with kgdb and vmm

2018-05-12 Thread Xavier Guerin
Hello, I'd like to dive into the bridge driver and I am trying to setup a kernel debugging environment. I chose to use VMM to do that but I don't seem to find a way to connect my local gdb to the VMM console. I guess I would need another serial device for KGDB, but I have not found how to do that
