Hi ,linuxppc-embedded ?
I have done the interrupt request by request_irq() on the
Linux 2.4.25 ,when typing the 'cat /proc/interrupts', I can see the information
as follow :
/proc # cat interrupts
CPU0
2: 3420 8xx SIU Edge wbga_interrupt
5: 0 8xx SIU Edge CPM cascade
15: 0 8xx SIU Edge tbint
16: 0 CPM Edge error
20: 801 CPM Edge SMC1
and I can see the number of wbga_interrupt is increasing. But a few minutes
later ,the number is locked at 128000 as follow:
/proc # cat interrupts
CPU0
2: 128000 8xx SIU Edge wbga_interrupt
5: 0 8xx SIU Edge CPM cascade
15: 0 8xx SIU Edge tbint
16: 0 CPM Edge error
20: 833 CPM Edge SMC1
and there is no wbga_interrupt any more....what's the matter with the
interrupt?why is 128000???
