Function Documentation

◆ mpcomm_main()

int mpcomm_main ( mpcomm_user_func_t  controller_user_func,
mpcomm_user_func_t  helper_user_func 
)

Start the MPCOMM framework on the controller or the helper. The user can register a callbacks that will handle the data received from the supervisor and controller.

Parameters
[in]controller_user_funcUser-defined callback for the contoller.
[in]helper_user_funcUser-defined callback for the helper.
Returns
On success, 0 is returned. On failure, negative value is returned according to <errno.h>.

◆ mpcomm_send_helper()

int mpcomm_send_helper ( uint8_t  helper_index,
void *  data 
)

Send the user data to the helper for processing.

Parameters
[in]helper_indexHelper index.
[in]dataUser data.
Returns
On success, 0 is returned. On failure, negative value is returned according to <errno.h>.

◆ mpcomm_wait_helper_done()

int mpcomm_wait_helper_done ( uint8_t  helper_index)

Wait until user data has been processed by helper.

Parameters
[in]helper_indexHelper index.
Returns
On success, 0 is returned. On failure, negative value is returned according to <errno.h>.

◆ mpcomm_wait_helpers_done()

int mpcomm_wait_helpers_done ( void  )

Wait until user data has been processed by all helpers.

Returns
On success, 0 is returned. On failure, negative value is returned according to <errno.h>.

◆ mpcomm_get_helpers_num()

int mpcomm_get_helpers_num ( void  )

Return number of helpers.

Returns
Number of helpers.

◆ mpcomm_is_controller()

bool mpcomm_is_controller ( void  )

Return true if it is controller. Otherwise, return false.

Returns
True, if it is controller.

◆ mpcomm_memory_virt_to_phys()

void * mpcomm_memory_virt_to_phys ( void *  addr)

Convert address from virtual to physical.

Parameters
[in]addrVirtual address.
Returns
Physical address.

◆ mpcomm_send_malloc()

int mpcomm_send_malloc ( void **  ptr,
size_t  size 
)

Send a request to the supervisor to call malloc() and save the address of the allocated memory in the ptr.

Parameters
[out]ptrThe address of the allocated memory received from the supervisor.
[in]sizeRequested size.
Returns
On success, 0 is returned. On failure, negative value is returned according to <errno.h>.

◆ mpcomm_send_free()

int mpcomm_send_free ( void *  ptr)
