Title: [Ubuntu 15.04] Support firmware assisted dump on ppc64le Status in linux package in Ubuntu: New Status in makedumpfile package in Ubuntu: In Progress Bug description: Starting from POWER6, the firmware now has a capability to preserve the partition memory dump during system crash and boot into a fresh copy of the kernel with fully-reset system. This feature adds the necessary support to exploit the dump capture capability provided by Power firmware. With this feature support, the production kernel will register for firmware-assisted dump using RTAS (Runtime Abstraction Service) calls and builds required ELF header which then gets exported through '/proc/vmcore' in the second kernel after crash. This feature improves Power serviceability by making it more robust compared to current kdump mechanism on Linux. Ubuntu 15.04 kernel already includes the necessary code for fadump. The only kernel change needed is to enable CONFIG_FA_DUMP in the kernel configuration. In addition, an update is needed for a script in kdump-tools package.
