When you repost the series, please be explicit about what the relationship between the new fadump facility and the old phyp-dump is, both in the documentation you're adding and in the patch descriptions.
I gather that fadump uses the same firmware interfaces as phyp-dump, and can be characterised as a rewrite of phyp-dump. It would be good if you would explicitly mention:
- What advantages fadump has over phyp-dump - Whether there are any capabilities that phyp-dump does that fadump doesn't - What is different between fadump and phyp-dump in the interface to usermode code - Any user-visible differences between how fadump operates compared to phyp-dump. For example, will users see a difference in how much memory is available to the kernel?
Paul.
