Interrupt Service Routines

Kernel interface is not accessible from the realm of interrupt service routines. Normally, interrupt service routines can’t call the kernel syscalls. This behavior is by design. The idea is to do as little of work in the context of the ISR handler and then either pass the CPU to the interrupted thread, or wake up some specific thread to finish the work. Calls present in this section are not system calls, can only be called from interrupt handler context.

Functions
