From 34c0dad752294f373a0720840f59e186788ba227 Mon Sep 17 00:00:00 2001 From: Michael Holzheu Date: Mon, 9 Feb 2015 14:49:10 +0100 Subject: [PATCH] s390/hypfs: Add diagnose 0c support With this feature, you can read the CPU performance metrics provided by the z/VM diagnose 0C. 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.
