Userland is useable however you have to tweak the dtb file. Recently I hacked kexec-tools so they can suck the dtb from /proc/device-tree while I've been traveling but I had no time to test it. Ah and initrd support as well. > Will they be included to main line? I hope so. I fixed what Kumar did not like in the last version. As far as I know, he had no time review it. > > As I understand 8572 board has to work with your kernel: > > http://git.breakpoint.cc/cgi-bin/gitweb.cgi?p=bigeasy/linux.git;a=shortlog;h=refs/heads/kexec_booke Not really. 8572 is SMP and SMP is not supported at the moment. The plan for SMP was - pin userland to the boot cpu - halt the other cpu in kernel during kexec - the what we do right now - use the ipic to reset the cpu and bring it back to virgin state. That was only the plan I made. Halt the CPU means spin I think so you should respect the "reserved region" in dtb. > I tried this kernel and result is hang after "Bye!". Which kexec-tools > is suitable for your kernel? Can you please throw them to me? [0] is what I used last time I checked and Simon merged it. So it should work. I try to rebase the kernel to v33 and see if it got broken somehow. Maybe I should merge console support so it is easier to debug. The plan here was to set the uart type & address into the purgatory code from what we know from the dtb. However I have no idea how to set the MMU mapping for it. > I posted the patch, which make 83xx classic powerpc work (not booke). > Both kexec and kdump.

I post the proc/dtb-suck-in patches once they are tested. I could push it to my pubic git tree if you want to look at them. SMP support is missing and I haven't looked at kdump at all.
