Macro Definition Documentation

◆ __instance_get_currthread

#define __instance_get_currthread ( oip ) (oip)->rlist.current

Current thread pointer get macro.

Note: This macro is not meant to be used in the application code but only from within the kernel, use chThdGetSelfX() instead.

Definition at line 56 of file chinstances.h.

◆ __instance_set_currthread

#define __instance_set_currthread	(	oip,
		tp
	)	(oip)->rlist.current = (tp)

Current thread pointer set macro.

Definition at line 61 of file chinstances.h.

Function Documentation

◆ __idle_thread()

static void __idle_thread ( void * p )

static

This function implements the idle thread infinite loop.

The function puts the processor in the lowest power mode capable to serve interrupts.
The priority is internally set to the minimum system value so that this thread is executed only if there are no other ready threads in the system.

Parameters

[in] p the thread parameter, unused in this scenario

Definition at line 62 of file chinstances.c.

References CH_CFG_IDLE_LOOP_HOOK, and port_wait_for_interrupt().

Here is the call graph for this function:

◆ chInstanceObjectInit()

void chInstanceObjectInit	(	os_instance_t *	oip,
		const os_instance_config_t *	oicp
	)

Initializes a system instance.

Note: The system instance is in I-Lock state after initialization.
