It can be used in the same way as e.g. /dev/mem. The dump format defines a 4K header followed by plain uncompressed memory. The register sets are stored in the prefix pages of the respective cpus. To build a dump enabled kernel with the zcore driver, the kernel config option -CONFIG_ZFCPDUMP has to be set. When reading from "zcore/mem", the part of +CONFIG_CRASH_DUMP has to be set. When reading from "zcore/mem", the part of memory, which has been saved by hardware is read by the driver via the SCLP hardware interface. The second part is just copied from the non overwritten real memory. @@ -32,7 +32,7 @@ SCSI disk.
