From mboxrd@z Thu Jan 1 00:00:00 1970 From: takahiro.akashi@linaro.org (AKASHI Takahiro) Date: Tue, 9 Aug 2016 10:52:47 +0900 Subject: [PATCH v24 0/9] arm64: add kdump support Message-ID: <20160809015248.28414-1-takahiro.akashi@linaro.org> To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.org This patch series adds kdump support on arm64. To load a crash-dump kernel to the systems, a series of patches to kexec-tools, which have not yet been merged upstream, are needed. Please use my kdump patches [1]. 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] T.B.D. [2] https://github.com/crash-utility/crash.git Changes for v24 (Aug 9, 2016): o Rebase to Linux-4.8-rc1 o Update descriptions about newly added DT proerties Changes for v23 (July 26, 2016): o Move memblock_reserve() to a single place in reserve_crashkernel() o Use cpu_park_loop() in ipi_cpu_crash_stop() o Always enforce ARCH_LOW_ADDRESS_LIMIT to the memory range of crash kernel o Re-implement fdt_enforce_memory_region() to remove non-reserve regions (for ACPI) from usable memory at crash kernel 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.
