檢視linux irq時間,linux – 如何判斷irqbalance是否正在執行任何操作？

在源代碼中,他們引用/ proc幾次.也許你在那裡找到答案.

root @ [/usr/local / src / irqbalance-0.55] egrep -ri“proc | sys”*

activate.c: sprintf(buf, "/proc/irq/%i/smp_affinity", irq->number);

cpumask.h: * set of CPU's in a system, one bit position per CPU number.

cpumask.h: * The following particular system cpumasks and operations manage

cpumask.h: * be plugged in at anytime during the life of that system boot.

cpumask.h:int highest_possible_processor_id(void);

cputree.c: * This file contains the code to construct and manipulate a hierarchy of processors,

cputree.c: * cache domains and processor cores.

cputree.c:#include

cputree.c: dir = opendir("/sys/devices/system/cpu");

cputree.c: sprintf(new_path, "/sys/devices/system/cpu/%s", entry->d_name);

irqbalance.c:#include

irqbalance.c:

irqlist.c: sprintf(buf, "/proc/irq/%i", number);
