Hi,
sel4platsupport_new_io_ops is defined in
libsel4platsupport/include/sel4platsupport/io.h , it creates a new
implementation of the platsupport io_ops interface using a provided simple,
vspace and vka, Here is its protocol:
/*
* @param simple Simple interface for getting the physical frames
* @param vspace VSpace interface to use for mapping
* @param vka VKA interface for allocating any extra objects or
cslots
* @param io_ops Interface to fill in
*
* @return returns 0 on success
*/
int sel4platsupport_new_io_ops(simple_t simple, vspace_t vspace,
vka_t vka, ps_io_ops_t *io_ops);
Who can give me a sample program using this function? I guess it
will be used in I/O DMA program, but I don't know much about DMA program.
