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 --- net/iucv/iucv.c | 2 ++ 1 file changed, 2 insertions(+) (limited to 'net/iucv') diff --git a/net/iucv/iucv.c b/net/iucv/iucv.c index f7db676de77d..1ee5dab3cfae 100644 --- a/net/iucv/iucv.c +++ b/net/iucv/iucv.c @@ -36,6 +36,7 @@ #define KMSG_COMPONENT "iucv" #define pr_fmt(fmt) KMSG_COMPONENT ": " fmt +#include #include #include #include @@ -1804,6 +1805,7 @@ static void iucv_external_interrupt(unsigned int ext_int_code, struct iucv_irq_data *p; struct iucv_irq_list *work; + kstat_cpu(smp_processor_id()).irqs[EXTINT_IUC]++; p = iucv_irq_data[smp_processor_id()]; if (p->ippathid >= iucv_max_pathid) { WARN_ON(p->ippathid >= iucv_max_pathid); -- cgit v1.2.3
