ARM w/40-bit physical address space and ARM64
 
Hi guys,

By any chance are you gents looking into updating the crash utility's
ARM support for its new 40-bit PAE capability, or the 64-bit ARM
architecture?

Dave

Sorry for the late response, I've been on vacation and unable to read my
email.

Unfortunately I don't have access to any newer ARM hardware that have larger
address space. If someone who has such hardware could provide a sample
vmlinux/vmcore files to me, I can do the implementation.

Lot of that going around lately... ;-)

Hi Mika,

I don't of the existence of any vmcores. Do you know off-hand if kdump would
work, or whether it's currently possible that a 40-bit PAE kernel can kexec itself?
Typically in the past with new arches I have always got crash working on the
live system first.

But anyway, I appreciate the offer -- good to know...

Thanks,
Dave

IIRC the address space extension wasn't that complex change and I would expect
that the kexec works out of the box. It is different with 64-bit ARM which is
regarded as a completely different arch (last time I checked) in the Linux
kernel world.

Good to know. I started the ARM port only when the kernel kexec/kdump support
was working and only added the live dump support in the last minute before we
submitted the ARM patches to you :)
