#ifndef _HARDWARE_MONITOR_H_ #define _HARDWARE_MONITOR_H_ /* Communication between servers (such as the RSP server) and the target * monitor is done via 2 pipes, created using pipe(). One pipe, pipe_fds[0], * is used by the server to command the target monitor thread to stall or * unstall the CPU. This is done by sending single-letter commands; sending "S" * commands the monitor thread to stall the CPU, sending "U" commands the monitor * to unstall the CPU. * * Feedback is sent back to servers using pipe_fds[1]. When the CPU transitions * from the stalled state to the run state, an "R" is sent to all registered * servers. When the CPU goes from running to stopped, an "H" is sent to indicate * the halt state. */ /* This should be called once at initialization */ int start_monitor_thread(void); /* This is called to create a pair of shared pipes with the monitor thread. * The pipes should NOT have already been created before calling this function, * but the pipe_fds array must be already allocated. pipe_fds[0] is for * communicating server->monitor, pipe_fds[1] is for monitor->server. */ int register_with_monitor_thread(int pipe_fds[2]); /* Un-share a set of pipes with the monitor. The pipes may be closed * after this call returns. */ void unregister_with_monitor_thread(int pipe_fds[2]); #endif
