This patch set implements firmware-assisted dump support for kdump service. Firmware-assisted dump support depends on existing kdump infrastructure (kdump scripts) present in userland to save dump to the disk. Though existing kdump script will work seemlessly, it still needs to modified to make it aware of presense of firmware- assisted dump feature during service start and stop. These changes are tested successfully on a power box with fedora19. Changes in v2: 1. Added dump_mode variable to store dump type to use during checks. 2. Split start, stop and rebuild routines for kdump and fadump. 3. Rebased to kexec-tools version 2.0.4-24. 4. Added fadump howto document. --- Hari Bathini (7): kdump: Modify status routine to check for firmware-assisted dump kdump: Modify kdump script to start the firmware assisted dump. kdump: Modify kdump script to stop firmware assisted dump kdump: Take a backup of original default initrd before rebuilding. kdump: Rebuild default initrd for firmware assisted dump kdump: Check for /proc/vmcore existence before capturing the vmcore. kdump: Add firmware-assisted dump howto document dracut-kdump.sh | 3 fadump-howto.txt | 428 ++++++++++++++++++++++++++++++++++++++++++++++++++++++ kdumpctl | 263 +++++++++++++++++++++++++++++---- 3 files changed, 660 insertions(+), 34 deletions(-) create mode 100644 fadump-howto.txt -- - Hari
