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 for MPIPL support: https://patchwork.ozlabs.org/project/skiboot/list/?series=119169 ("MPIPL support") Changes in v4: * Split the patches. * Rebased to latest upstream kernel version. * Updated according to latest OPAL changes. --- Hari Bathini (25): powerpc/fadump: move internal macros/definitions to a new header powerpc/fadump: move internal code to a new file powerpc/fadump: Improve fadump documentation pseries/fadump: move rtas specific definitions to platform code pseries/fadump: introduce callbacks for platform specific operations pseries/fadump: define register/un-register callback functions pseries/fadump: move out platform specific support from generic code powerpc/fadump: use FADump instead of fadump for how it is pronounced opal: add MPIPL interface definitions powernv/fadump: add fadump support on powernv powernv/fadump: register kernel metadata address with opal powernv/fadump: define register/un-register callback functions powernv/fadump: support copying multiple kernel memory regions powernv/fadump: process the crashdump by exporting it as /proc/vmcore powerpc/fadump: Update documentation about OPAL platform support powerpc/fadump: consider reserved ranges while reserving memory powerpc/fadump: consider reserved ranges while releasing memory powernv/fadump: process architected register state data provided by firmware powernv/fadump: add support to preserve crash data on FADUMP disabled kernel powerpc/fadump: update documentation about CONFIG_PRESERVE_FA_DUMP powernv/opalcore: export /sys/firmware/opal/core for analysing opal crashes powernv/fadump: Warn before processing partial crashdump powernv/opalcore: provide an option to invalidate /sys/firmware/opal/core file powernv/fadump: consider f/w load area powernv/fadump: update documentation about option to release opalcore Documentation/powerpc/firmware-assisted-dump.txt | 224 +++- arch/powerpc/Kconfig | 23 arch/powerpc/include/asm/fadump.h | 190 ---- arch/powerpc/include/asm/opal-api.h | 50 + arch/powerpc/include/asm/opal.h | 6 arch/powerpc/kernel/Makefile | 6 arch/powerpc/kernel/fadump-common.c | 153 +++ arch/powerpc/kernel/fadump-common.h | 203 ++++ arch/powerpc/kernel/fadump.c | 1181 ++++++++-------------- arch/powerpc/kernel/prom.c | 4 arch/powerpc/platforms/powernv/Makefile | 3 arch/powerpc/platforms/powernv/opal-call.c | 3 arch/powerpc/platforms/powernv/opal-core.c | 637 ++++++++++++ arch/powerpc/platforms/powernv/opal-fadump.c | 671 ++++++++++++ arch/powerpc/platforms/powernv/opal-fadump.h | 154 +++ arch/powerpc/platforms/pseries/Makefile | 1 arch/powerpc/platforms/pseries/rtas-fadump.c | 595 +++++++++++ arch/powerpc/platforms/pseries/rtas-fadump.h | 123 ++ 18 files changed, 3231 insertions(+), 996 deletions(-) create mode 100644 arch/powerpc/kernel/fadump-common.c create mode 100644 arch/powerpc/kernel/fadump-common.h create mode 100644 arch/powerpc/platforms/powernv/opal-core.c create mode 100644 arch/powerpc/platforms/powernv/opal-fadump.c create mode 100644 arch/powerpc/platforms/powernv/opal-fadump.h create mode 100644 arch/powerpc/platforms/pseries/rtas-fadump.c create mode 100644 arch/powerpc/platforms/pseries/rtas-fadump.h
