函数说明

osal_arch_dcache_flush_by_va()

void osal_arch_dcache_flush_by_va	(	void *	base_addr,
		unsigned int	size
	)

flush DCache.

Description:

This API is used to flush DCache.

Support System:

seliteos.

osal_arch_dcahce_inv_by_va()

void osal_arch_dcahce_inv_by_va	(	void *	base_addr,
		unsigned int	size
	)

invalid DCache.

Description:

This API is used to invalid DCache.

Support System:

seliteos.

osal_dcache_region_clean()

void osal_dcache_region_clean	(	void *	addr,
		unsigned int	size
	)

clean DCache.

Description:

This API is used to clean DCache.

Support System:

liteos.

Description: This API is used to clean DCache.

注意

The API will clean DCache according to based address and input size.

osal_dcache_region_inv()

void osal_dcache_region_inv	(	void *	addr,
		unsigned long	size
	)

invalid DCache.

Description:

This API is used to invalid DCache.

注意

The base address will be aligned to CACHE_LINE_SIZE(32Bytes) if it's not aligned to CACHE_LINE_SIZE.

参数

addr	[in] The start address need flush.
size	[in] The size of flush memory.

Support System:

linux liteos seliteos.

invalid DCache.

参数

addr	[IN] The start address need invalid.
size	[IN] The size of invalid memory.

osal_dcache_region_wb()

void osal_dcache_region_wb	(	void *	kvirt,
		unsigned long	phys_addr,
		unsigned long	size
	)

flush DCache.

Description:

This API is used to flush DCache.

注意

The base address will be aligned to CACHE_LINE_SIZE(32Bytes) if it's not aligned to CACHE_LINE_SIZE. Make sure that phys_addr is valid when mmu does not exist, and user set its addr in kvirt.

参数

kvirt	[in] kvirt.
phys_addr	[in] The start address need flush.
size	[in] The size of flush memory.

Support System:

linux liteos seliteos.

flush DCache.

参数

phys_addr	[IN] The start address need flush.
size	[IN] The size of flush memory.
