Function Documentation

int _set_memory_uc	(	unsigned long	addr,
		int	numpages
	)

Definition at line 967 of file pageattr.c.

int _set_memory_wb	(	unsigned long	addr,
		int	numpages
	)

Definition at line 1090 of file pageattr.c.

int _set_memory_wc	(	unsigned long	addr,
		int	numpages
	)

Definition at line 1049 of file pageattr.c.

void clflush_cache_range	(	void *	vaddr,
		unsigned int	size
	)

clflush_cache_range - flush a cache range with clflush : virtual start address : number of bytes to flush

clflush is an unordered instruction which needs fencing with mfence to avoid ordering issues.
