This then allows to get the management time for each online CPU of the guest where the diagnose is executed. The new debugfs file /sys/kernel/debug/s390_hypfs/diag_0c exports the diag0C binary data to user space via an open/read/close interface. The binary data consists out of a header structure followed by an array that contains the diagnose 0c data for each online CPU.

All other diagnose 0x304 requests need to be submitted via ioctl with CAP_SYS_ADMIN rights. Signed-off-by: Martin Schwidefsky <schwidefsky@de.ibm.com>
