Subject: [PATCH v5 00/31] Add FADump support on PowerNV platform
Date: Tue, 20 Aug 2019 17:34:05 +0530 [thread overview]
Message-ID: <156630261682.8896.3418665808003586786.stgit@hbathini.in.ibm.com> (raw)
Firmware-Assisted Dump (FADump) is currently supported only on pSeries
platform. This patch series adds support for PowerNV platform too.
The first few patches refactor the FADump code to make use of common
code across multiple platforms. Then basic FADump support is added for
PowerNV platform. Followed by patches to honour reserved-ranges DT node
while reserving/releasing memory used by FADump. The subsequent patch
processes CPU state data provided by firmware to create and append core
notes to the ELF core file and the next patch adds support to preserve
crash data for subsequent boots (useful in cases like petitboot). The
subsequent patches add support to export opalcore. opalcore makes
debugging of failures in OPAL code easier. Firmware-Assisted Dump
documentation is also updated appropriately.
The patch series is tested with the latest firmware plus the below skiboot
changes, accepted upstream recently, for MPIPL support:
https://patchwork.ozlabs.org/project/skiboot/list/?series=119169
("MPIPL support")
Changes in v5:
* Split the patches further.
* Rebased to latest upstream kernel version.
* Updated the patches based on discussions with mahesh on V4.
