Interrupt service routines

Description

Routines available from running interrupt service routine context.

By default, all the interrupt service routines have higher priority than the kernel service call handler. CMRX is not expecthing this to change. This configuration causes that service call handler is not callable from within interrupt service handlers. Following routines are provided so that interrupt service routines can ask kernel to perform certain tasks while in servicing interrupt.

Never perform direct calls into kernel other than methods listed in this group. These methods are not reentrant and calling them from within interrupt handler may corrupt kernel internal state.

Functions
void	isr_kill (Thread_t thread_id, uint32_t signal)
	Send signal from ISR context.

Function Documentation

isr_kill()

void isr_kill	(	Thread_t	thread_id,
		uint32_t	signal
	)

Send signal from ISR context.

This routine is an equivalent of kill() syscall, which is usable from interrupt service routine context.

Parameters

thread_id	thread, which should receive the signal
signal	signal to be sent
