Hi, I run cat /proc/interrupts on Feodra 18 x86_64 machine, and I get these results (after 1 hour the machine is up)
0: 127 0 IO-APIC-edge timer .. 4: 1 1 IO-APIC-edge ...
question 1: we see 127 timer interrupts on core 1. It seems that these 127 interrupts occur immediately in boot or in a short while afterwards, as it seems that they are not progressing. Why do we need at all this timer (on IRQ0) ? there is an apic timer: cat /proc/interrupts shows that it is incrementing all the time: cat /proc/interrpts | grep LOC: LOC: 288967 289350 Local timer interrupts
question 2: what is interrupt 4 ? it does not show any description.Also, there is only 1 interrupt on it (on both cores).
Rgs, Kevin
