Stefan,
I got the smp branch of your repo ("git clone --branch smp
git://git.openrisc.net/stefan/linux") and then ran the following steps:
1. Made sure I had added "CROSS_COMPILE=or32-elf-" and "export
CROSS_COMPILE" to my .bashrc.
2. Ran "make defconfig" to generate the or1ksim-compatible configs.
3. Ran "make" to get a vmlinux that should work with or1ksim.
4. Edited arch/openrisc/or1ksim.cfg, section uart:
a. Commented out channel = "tcp:10084"
b. Uncommented channel = "xterm:"
5. Ran "or32-elf-sim -f arch/openrisc/or1ksim.cfg vmlinux", but I got a
kernel panic (see below).
Are there other things I should've configured differently first using "make
menuconfig" before running or1ksim? Should I have skipped running "make
defconfig" and just run "make menuconfig" instead? (I wasn't sure about all
the options.)
Thanks,
Daniel

You can try the smp branch from my repo, I know that the framebuffer
works with that at least
[LINK: http://git.openrisc.net/cgit.cgi/stefan/linux/tree/arch?h=smp]
http://git.openrisc.net/cgit.cgi/stefan/linux/tree/arch?h=smp
It's currently based on linux-3.17.

This is not what I pasted earlier, it should be
compatible = "opencores,ocfb";
to find out the correct compatible strings, you can search the
drivers/ directory for them .�
