Subject: Re: pkg/51103: Updates for ski emulator
Date: Fri, 6 May 2016 15:29:40 -0400

 Below is another patch that fixes newline/carriage problems for
 ski-fake-xterm with both skiload and netbsd kernel printouts.
 
 I'm getting close to having the ski emulator run a SKI kernel, here is
 a dmesg from the sim.  It seems like there still is an off-by-one bug
 with doSSC system call not decoding args/registers that I don't
 totally understand yet.  I don't know if the problem is a ski or
 kernel issue yet, but with my hack I can get console messages.
 
 By the way, this sim output and real hardware
 (http://gnats.netbsd.org/49717), look like they die at about the same
 place (pmap.c/pmap.h doesn't work).  One thing ski still doesn't do is
 decode source code lines which is probably the next thing to look at
 after doSSC() issues are sorted.
