Subject: [PATCH 0/4] kexec-tools, x86: E820 memmap pass for kdump
Date: Thu, 13 Feb 2014 21:10:51 +0800 [thread overview]
Message-ID: <1392297055-31934-1-git-send-email-chaowang@redhat.com> (raw)
Hi, All
When kaslr comes in and kdump is broken, it seems about the right time to use
E820 instead of memmap=exactmap to pass memmap for kdump for the default memmap
passing mechanism:
http://lists.infradead.org/pipermail/kexec/2014-February/011048.html
Unfortunately, saved_max_pfn still got its user out there (calgry pci, it looks
like the only one). So for backward compatibility, I'm introducing a new option
--pass-memmap-cmdline to force kexec-tools to pass memmap=exactmap, the old way.
Any comment is appreciate!
WANG Chao (4):
add macro dbgprint_mem_range
x86: Store memory ranges globally used for crash kernel to boot into
x86: add --pass-memmap-cmdline option
x86: Pass memory range via E820 for kdump
