Hello Liu,

I'm curious how you tested this?  The crash utility does not have
any specific support for LPAE on ARM, and a couple years ago I 
asked on the crash-utility mailing list whether any of the ARM
developers were working on it.  But at that time none of them were
working with LPAE.  I see that you are on the crash-utility mailing
list -- are you planning to post follow-up patches to the crash-utility?

Thanks,
  Dave

Yes, you are very "sensitive"! our team has worked on it for a while. And
we went through the whole kdump process for LPAE enabled ARM. Our changes
include kexec-tools, makedumpfile, crash utility and the kernel.

But we did that in a rather limited time. So some patches are silly and
need to be reconstructed before submission. In addition, my job is quit
full now. So I decide to post the patch series that are clear and
independent of the others at first.

But I got no response from the linux-arm and kexec mailinglist. What about
your opinion about the feature of LPAE support for kdump related tools
including crash utility and the kernel?

Thanks,
Liu Hua

I can't speak for the linux-arm and kexec mailing lists, but certainly 
when you post your crash-related patches on the crash-utility mailing 
list, I'll review, respond, and get them in place as soon as possible.

Thanks,
  Dave

Hi Dave,

That's great. I will post crash-related patches after finishing my
work on hand, perhaps two weeks or longer. Thanks to your advice.

Thanks,
Liu Hua
