armDCacheClean()

void armDCacheClean	(	void *	addr,
		size_t	size
	)

Performs a data cache clean on the specified buffer.

Parameters

addr	Address of the buffer.
size	Size of the buffer, in bytes.

Note

The start and end addresses of the buffer are forcibly rounded to cache line boundaries (read from CTR_EL0 system register).

armDCacheFlush()

void armDCacheFlush	(	void *	addr,
		size_t	size
	)

Performs a data cache flush on the specified buffer.

Parameters

addr	Address of the buffer.
size	Size of the buffer, in bytes.

Remarks

Cache flush is defined as Clean + Invalidate.

Note

The start and end addresses of the buffer are forcibly rounded to cache line boundaries (read from CTR_EL0 system register).

armDCacheZero()

void armDCacheZero	(	void *	addr,
		size_t	size
	)

Performs a data cache zeroing operation on the specified buffer.

Parameters

addr	Address of the buffer.
size	Size of the buffer, in bytes.

Note

The start and end addresses of the buffer are forcibly rounded to cache line boundaries (read from CTR_EL0 system register).

armICacheInvalidate()

void armICacheInvalidate	(	void *	addr,
		size_t	size
	)

Performs an instruction cache invalidation clean on the specified buffer.

Parameters

addr	Address of the buffer.
size	Size of the buffer, in bytes.

Note

The start and end addresses of the buffer are forcibly rounded to cache line boundaries (read from CTR_EL0 system register).
