Function Documentation

void rtems_cache_flush_entire_data

(

void

)

This function is responsible for performing a data cache flush.

It flushes the entire cache.

void rtems_cache_flush_multiple_data_lines	(	const void *	,
		size_t
	)

This function is called to flush the data cache by performing cache copybacks.

It must determine how many cache lines need to be copied back and then perform the copybacks.

void rtems_cache_invalidate_entire_data

(

void

)

This function is responsible for performing a data cache invalidate.

It invalidates the entire cache.

void rtems_cache_invalidate_entire_instruction

(

void

)

This function is responsible for performing an instruction cache invalidate.

It invalidates the entire cache.

void rtems_cache_invalidate_multiple_data_lines	(	const void *	,
		size_t
	)

This function is responsible for performing a data cache invalidate.

It must determine how many cache lines need to be invalidated and then perform the invalidations.

void rtems_cache_invalidate_multiple_instruction_lines	(	const void *	,
		size_t
	)

These functions will ONLY do something if the libcpu support includes instruction cache routines AND the CPU model supports instruction caching.

This function is responsible for performing an instruction cache invalidate. It must determine how many cache lines need to be invalidated and then perform the invalidations.
