-Instructions for building and running the FreeBSD kernel under PSIM:
-
-1. On a FreeBSD system, check out a new source tree and run:
- # cd src/sys/powerpc/conf
- # config -g GENERIC
-
-2. On a NetBSD PPC system with the source NFS mounted, compile the kernel
- (your mount point may vary):
- # make -m /mnt/share/mk MACHINE_ARCH=powerpc
-
-3. On the FreeBSD system, grap /usr/src/release/write_mfs_in_kernel.c and
- run it using <http://people.freebsd.org/~mp/psim/ppcdisk.bz2> to add
- the md image:
-
- # ./write_mfs_in_kernel kernel.debug ppcdisk
-
-4. Run the simulator. The following .gdbinit is available as
- /usr/local/share/examples/psim-freebsd/dot.gdbinit:
-
- display/i $pc
- define pglobal
- print *(struct globaldata *)$sprg0
- end
- target sim -e chirp -r 33554432
- set architecture powerpc:604
- load
