[Xen-devel] [PATCH 0/2] extract vmcoreinfo from /proc/vmcore for Xen

[Itsuro ODA <oda@xxxxxxxxxxxxx>]

Hi,

The following patchset is to support extracting vmcoreinfo from
/proc/vmcore for Xen.

This is the up-port of the patchset I made for 3.2.0 and posted
the end of March.

[PATCH 1/2] patch for xen hypervisor (xen-unstable.hg)
[PATCH 2/2] patch for linux (linux-2.6.18-xen.hg)

--- background ----------------------------------------------------
* what the makedumpfile is:
  To shorten the size of the dumpfile and the time of creating the
  dumpfile, makedumpfile copies only the necessary pages for analysis
  to the dumpfile from /proc/vmcore. You can specify the kind of
  unnecessary pages with dump_level. If you want to shorten the size
  further, enable the compression of the page data.
* Xen extraction 
  makedumpfile also has a feature that extracting the part of
  xen hypervisor and domain-0 from /proc/vmcore taken under xen
  environment. In most cases under xen environment, it is enough to
  analyze a cause of system crash.
* extract vmcoreinfo from /proc/vmcore
  makedumpfile 1.2.0 supports to extract the vmcoreinfo data from
  /proc/vmcore and uses it for dump filtering. (for a vmcore taken
  under the native environment.)
