Detailed Description

This file contains functions for memory mapping None of the described functions will check the input parameters so the behavior of the APIs in illegal parameters case is dependent on the operating system behavior.

Function Documentation

uint32_t SaSi_PalMemMap	(	uint32_t	physicalAddress ,
		uint32_t	mapSize ,
		uint32_t **	ppVirtBuffAddr
	)

This function purpose is to return the base virtual address that maps the base physical address.

Returns

Zero on success.

A non-zero value in case of failure.

Parameters

[in]	physicalAddress	Start physical address of the I/O range to be mapped.
[in]	mapSize	Number of bytes that were mapped.
[out]	ppVirtBuffAddr	Pointer to the base virtual address to which the physical pages were mapped.

uint32_t SaSi_PalMemUnMap	(	uint32_t *	pVirtBuffAddr ,
		uint32_t	mapSize
	)

This function purpose is to Unmap a specified address range previously mapped by SaSi_PalMemMap.

Returns

Zero on success.

A non-zero value in case of failure.

Parameters

[in]	pVirtBuffAddr	Pointer to the base virtual address to which the physical pages were mapped.
[in]	mapSize	Number of bytes that were mapped.
