I got exactly what i was looking for. Zefram made this article more valuable .Through Zefram's comments we see that edge -triggered has more advantageous(handling the Unknown device interrupt and interrupt -storm handling,). I have a doubt,despite the advantage of edge -triggered why PCI designers have gone for Level Triggered ? ~Suresh Very nice article.. I got exactly what i was looking for.

You probably can do that with IPIs (Inter-processor interrupts), and you can also use the HPET (High precision event timer) in order to get a single or a periodic interrupt. quest, I’m not sure I understood you, what exactly are you trying to do?

My appologies if my questions are too silly:( is it possible for a programmer to generate interrupt to CPU without using Interrupt Controller? is it going to be very complex to do so? what would have happened if there was no interrupt controller at all?
please let me know. My appologies if my questions are too silly:(

Do you have any idea of using APIC timers in 2.6 kernel. I was looking for a patch for APIC timer for the present kernel (2.6). However, all I got were patches for older kernels. Have the patches been merged into the kernel source tree? Any ideas would be appreciated. Nice post. Do you have any idea of using APIC timers in 2.6 kernel.

It is part of the CPU in modern architecture, and hence it is called "Local". It means that, LAPIC == APIC. The LAPIC has several fucntions that I mentioned in the post itself.
