Subject: [PATCH v22 0/8] arm64: add kdump support
Date: Tue, 12 Jul 2016 14:05:06 +0900	[thread overview]
Message-ID: <20160712050514.22307-1-takahiro.akashi@linaro.org> (raw)

This patch series adds kdump support on arm64.

To load a crash-dump kernel to the systems, a series of patches to
kexec-tools [1], which have not yet been merged upstream, are needed.
Please update to the latest if you have been using an older version.

To examine vmcore (/proc/vmcore) on a crash-dump kernel, you can use
  - crash utility (coming v7.1.6 or later) [2]
    (Necessary patches have already been queued in the master.)

[1]  https://git.kernel.org/cgit/linux/kernel/git/geoff/kexec-tools.git
     (Please rename "linux,usable-memory" to "linux,usable-memory-range"
      in kexec/arch/arm64/kexec-arm64.c)
[2]  https://github.com/crash-utility/crash.git

Changes for v22 (July 12, 2016):

  o Export "crashkernel-base" and "crashkernel-size" via device-tree,
    and add some descriptions about them in chosen.txt
  o Rename "usable-memory" to "usable-memory-range" to avoid inconsistency
    with powerpc's "usable-memory"
  o Make cosmetic changes regarding "ifdef" usage
  o Correct some wordings in kdump.txt

Changes for v21 (July 6, 2016):

  o Remove kexec patches.
  o Rebase to arm64's for-next/core (Linux-4.7-rc4 based).
  o Clarify the description about kvm in kdump.txt.
