* Some notes about timer interrupt handling in Linux
On an SMP system APIC is used - the interesting file is arch/i386/kernel/apic.c
On UP systems, the normal IRQ0 is used
When the interrupt happens,
entry.S
calls do_IRQ, which sets up the special interrupt stack,
and calls __do_IRQ, which is in /kernel/irq/handle.c.
This calls the corresponding irqaction, which has previously
been setup by arch/i386/mach-default/setup.c to point to
timer_interrupt, which is in arch/i386/kernel/time.c.
This calls do_timer_interrupt_hooks() which is defined in
/include/asm-i386/mach-default/do_timer.h. This function
then calls profile_tick().
Note when the CPU switches from user mode to kernel mode, it
pushes SS/ESP on top of the kernel stack, but when it switches
from kernel mode to kernel mode, it does _not_ push SS/ESP.
It does in both cases push EIP though.
Later:
- See if it is possible to group the X server activity under the process that
