From 052ff461c8427629aee887ccc27478fc7373237c Mon Sep 17 00:00:00 2001 From: Heiko Carstens Date: Wed, 5 Jan 2011 12:47:28 +0100 Subject: [S390] irq: have detailed statistics for interrupt types Up to now /proc/interrupts only has statistics for external and i/o interrupts but doesn't split up them any further. This patch adds a line for every single interrupt source so that it is possible to easier tell what the machine is/was doing. Part of the output now looks like this; CPU0 CPU2 CPU4 EXT: 3898 4232 2305 I/O: 782 315 245 CLK: 1029 1964 727 [EXT] Clock Comparator IPI: 2868 2267 1577 [EXT] Signal Processor TMR: 0 0 0 [EXT] CPU Timer TAL: 0 0 0 [EXT] Timing Alert PFL: 0 0 0 [EXT] Pseudo Page Fault [...] NMI: 0 1 1 [NMI] Machine Checks Signed-off-by: Heiko Carstens Signed-off-by: Martin Schwidefsky --- arch/s390/mm/fault.c | 2 ++ 1 file changed, 2 insertions(+) (limited to 'arch/s390/mm') diff --git a/arch/s390/mm/fault.c b/arch/s390/mm/fault.c index fe5701e9efbf..839b16df72b3 100644 --- a/arch/s390/mm/fault.c +++ b/arch/s390/mm/fault.c @@ -10,6 +10,7 @@ * Copyright (C) 1995 Linus Torvalds */ +#include #include #include #include @@ -543,6 +544,7 @@ static void pfault_interrupt(unsigned int ext_int_code, struct task_struct *tsk; __u16 subcode; + kstat_cpu(smp_processor_id()).irqs[EXTINT_PFL]++; /* * Get the external interruption subcode & pfault * initial/completion signal bit.
