The NGDump DT interface enables zgetdump to display various meta information contained within a dump partition prepared for NGDump stand-alone dump. Usage example: -------------- No dump yet made ---------------- $ zgetdump -d /dev/nvme0n1 Dump device info: Dump tool.........: Next Generation (NGDump) dump tool Version...........: 1 Architecture......: s390x (64 bit) Partition info: Partition number..: 1 Dump present ------------ $ zgetdump -d /dev/nvme0n1 Dump device info: Dump tool.........: Next Generation (NGDump) dump tool Version...........: 1 Architecture......: s390x (64 bit) Partition info: Partition number..: 1 Meta info: File..............: dump.elf Alternative disk path --------------------- $ zgetdump -d /dev/disk/by-id/nvme-eui.01000000010000005cd2e4c5bc845051 Dump device info: Dump tool.........: Next Generation (NGDump) dump tool Version...........: 1 Architecture......: s390x (64 bit) Partition info: Partition number..: 1 Meta info: File..............: dump.elf Signed-off-by: Alexander Egorenkov <egorenar@linux.ibm.com> Reviewed-by: Alexander Gordeev <agordeev@linux.ibm.com> Reviewed-by: Mikhail Zaslonko <zaslonko@linux.ibm.com> Tested-by: Mikhail Zaslonko <zaslonko@linux.ibm.com> Signed-off-by: Jan Höppner <hoeppner@linux.ibm.com>
