[PATCH v4 0/8] kdump: Modify kdump init script to support firmware-assisted dump

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 v4: 1. Using a global variable DUMP_MODE to store current dump mode. 2. Updated the fadump-howto.txt doc based on review comments. --- Hari Bathini (8): 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: Get rid of "function" keyword from all functions kdump: Check for /proc/vmcore existence before capturing the vmcore. kdump: Add firmware-assisted dump howto document dracut-kdump.sh | 3 + fadump-howto.txt | 250 +++++++++++++++++++++++++++++++++++++++++++ kdumpctl | 312 ++++++++++++++++++++++++++++++++++++++++++++++-------- 3 files changed, 516 insertions(+), 49 deletions(-) create mode 100644 fadump-howto.txt -- -Hari
