# @package PowerNVDump.py
# This module can contain testcases related to Firmware & Kernel dump feature
# including kdump, fadump aka MPIPL, opaldump, etc.
#
# fadump aka MPIPL:
# The goal of firmware-assisted dump is to enable the dump of
# a crashed system, and to do so from a fully-reset system.
# For more details refer
# https://www.kernel.org/doc/Documentation/powerpc/firmware-assisted-dump.txt
#
# kdump:
# Kdump uses kexec to quickly boot to a dump-capture kernel whenever a
# dump of the system kernel's memory needs to be taken (for example, when
# the system panics).
# For more details refer
# https://www.kernel.org/doc/Documentation/kdump/kdump.txt
#
# opaldump:
# With MPIPL we support capturing opalcore. We can use gdb to debug OPAL
# issues. For details refer `doc/mpipl.rst` under skiboot source tree.
#
# Test scenarios:
# 1. Verify SBE initiated MPIPL flow (trigger SBE S0 interrupt directly)
# 2. Verify OPAL crash (trigger OPAL assert via pdbg)
# 3. Enable fadump - trigger a kernel crash
# 4. Enable kdump - trigger a kernel crash
# 5. Disable dump - trigger a kernel crash
#
# and verify boot progress and collected dump components
# (vmcore and opalcore).
#
# NOTE: For remote kdump, network to be configured manually via static sysfs IP, before test starts.
