From: Cliff Wickman <[email protected]> I am submitting 6 patches that I have found helpful in speeding the dump process or clarifying the progress report. They are not a series, and should not be interdependent. But if you find any dependencies I apply them in this order: [PATCH] makedumpfile: reverse -c and -p if using snappy compression [PATCH] makedumpfile: use non-cyclic when possible [PATCH] makedumpfile: shorten cyclic exclude-unnecessary passes [PATCH] makedumpfile: shorten cyclic unnecessary-page scans [PATCH] makedumpfile: show needed memory [PATCH] makedumpfile: search for a debug vmlinux
The last one (search for a debug vmlinux) is useful in identifying huge pages with the PG_head/PG-tail flags. There was a patch from Petr Tesarik that enables that huge page filtering. I don't think you are taking that one as-is, but are reworking it. Seems like Hatayama-san was doing that work. That one is very important and I need to include Petr's version in any makedumpfile that we use in a very large system. I hope that one is coming along for inclusion in the next release. -Cliff Wickman _______________________________________________ kexec mailing list [email protected] http://lists.infradead.org/mailman/listinfo/kexec
