| |
hi,
I am looking for a way to program the APIC timer in a kernel module so that the module depends only on the hardware timer instead of the timer provided by the kernel. Programming the LVT is easy, however I can't find a way to have the Linux kernel to call my interrupt service routine in addition to smp_apic_timer_interrupt().
Is doing this even possible? There doesn't seem to be any sort of hook or notifier chain I can install a ISR to. Thanks in advance.
Regards,
YM
