This is a set of patches to add kexec support for m68k to the Linux kernel.
- Kexec only, no kdump support yet (do you have enough RAM to keep a
crashdump kernel in memory at all times? ;-)
- Tested on ARAnyM, with emulated 68040 (Atari has identical virt/phys RAM
mapping),
- Tested on Amiga 4000/040, with real 68040 (Amiga has non-identical
virt/phys RAM mapping).
- Test results on machines with different CPUs would be welcome!
You can download a kexec binary from
http://users.telenet.be/geertu/Download/kexec-m68k-2013-10-15.tar.bz2
- To have automatic "kexec -e" on reboot, copy /etc/rc6.d/S85kexec from
another system, and fix it up for kexec living in /usr/local/sbin instead
of /sbin.
- Sample invocation:
kexec -d -l vmlinux --reuse-cmdline
reboot
Patches:
- [PATCH 1/2] m68k: Add kexec support
- v2:
- KEXEC depends on M68KCLASSIC,
- Fix handling of virtual and physical addresses, for machines where
memory doesn't start at zero,
- Support for other CPUs than 68040.
- v3:
- Clear '040/'060 transparent translation registers on MMU disable
- [PATCH 2/2] m68k: Add support to export bootinfo in procfs
- v2:
- No changes
- v3:
- Rebased on top of current m68k tree
- "m68k: Add System RAM to /proc/iomem" was dropped in v2.
- "kexec: Add debug printing of kimage table entries" was dropped in v3.
Have fun!
