Function Documentation

◆ SDL_OSAL_init()

int32_t SDL_OSAL_init ( SDL_OSAL_Interface * osalInterface )

OSAL init.

This function initializes the OSAL interface structure with the functions provided by the application. These functions are application dependent, so it is required to be passed by the user.

Parameters

osalInterface [IN] OSAL interface structure.

Returns: The SDL error code for the API. If osalInterface is NULL: SDL_EBADARGS If other error happened: SDL_EFAIL Success: SDL_PASS

◆ SDL_OSAL_enableInterrupt()

int32_t SDL_OSAL_enableInterrupt ( int32_t intNum )

OSAL enable interrupt.

This function will enable the specific interrupt number passed.

Parameters

intNum [IN] Interrupt Number

Returns: The SDL error code for the API. If function pointer in interface is NULL: SDL_EBADARGS If other error happened: SDL_EFAIL Success: SDL_PASS

◆ SDL_OSAL_disableInterrupt()

int32_t SDL_OSAL_disableInterrupt ( int32_t intNum )

OSAL disable interrupt.

This function will disable the specific interrupt number passed.

Parameters

intNum [IN] Interrupt Number

Returns: The SDL error code for the API. If function pointer in interface is NULL: SDL_EBADARGS If other error happened: SDL_EFAIL Success: SDL_PASS

◆ SDL_OSAL_registerInterrupt()

int32_t SDL_OSAL_registerInterrupt	(	SDL_OSAL_hwipParams *	pParams,
		pSDL_OSAL_hwipHandle *	handle
	)

OSAL register interrupt.

This function will register the specific interrupt number passed.

Parameters

pParams	[IN] Parameters for interrupt registration
handle	[OUT] Handle for this registered interrupt

Returns: The SDL error code for the API. If function pointer in interface is NULL: SDL_EBADARGS If other error happened: SDL_EFAIL Success: SDL_PASS

◆ SDL_OSAL_deregisterInterrupt()

int32_t SDL_OSAL_deregisterInterrupt ( pSDL_OSAL_hwipHandle handle )

OSAL deregister interrupt.

This function will deregister the specific interrupt number passed.

Parameters

handle [IN] Handle for the registered interrupt

Returns: The SDL error code for the API. If function pointer in interface is NULL: SDL_EBADARGS If other error happened: SDL_EFAIL Success: SDL_PASS

◆ SDL_OSAL_globalDisableInterrupts()

int32_t SDL_OSAL_globalDisableInterrupts ( uintptr_t * key )

OSAL globally disable interrupts.

This function will disable interrupts globally. Interrupts can be enabled with the globalRestoreInterrupts() function. Usually used for critical sections.

The returned key is used to restore the context once interrupts are restored.

Parameters

key	[OUT] key to use when restoring interrupts

Returns: The SDL error code for the API. If function pointer in interface is NULL: SDL_EBADARGS If other error happened: SDL_EFAIL Success: SDL_PASS

◆ SDL_OSAL_globalRestoreInterrupts()

int32_t SDL_OSAL_globalRestoreInterrupts ( uintptr_t key )

OSAL globally enable interrupts.

This function will enable interrupts globally. Usually used for critical sections.

The key is used to restore the context.

Parameters

key	[IN] key to use when restoring interrupts

Returns: The SDL error code for the API. If function pointer in interface is NULL: SDL_EBADARGS If other error happened: SDL_EFAIL Success: SDL_PASS

◆ SDL_OSAL_printf()

void SDL_OSAL_printf ( const char * traceBuf )

OSAL print function.

This function prints the provided string

Parameters

traceBuf [IN] String to be printed

Returns: None

◆ SDL_OSAL_delay()

int32_t SDL_OSAL_delay ( int32_t ndelay )

OSAL delay.

This function is used assign delay in the function

Parameters

ndelay [IN] delay in microseconds

Returns: The SDL error code for the API. If function pointer in interface is NULL: SDL_EBADARGS If other error happened: SDL_EFAIL Success: SDL_PASS

◆ SDL_OSAL_addrTranslate()

void* SDL_OSAL_addrTranslate	(	uint64_t	addr,
		uint32_t	size
	)

OSAL Address translation function.

This function is used by the SDL to get a translation for a 64-bit address to local address space. It is expected that the requested adddress will remain available at the returned address and not be removed.

Parameters

addr	[IN] Memory address to be translated
size	[IN] Size of the memory

Returns: The translated address or (-1) for failure.
