Hi guys,
Apologies if this question has already been answered elsewhere on this mailing list. We are porting our driver to L4Linux but having issues with the page_to_phys() Linux function, what's the L4Linux API to map a VM physical address to a machine address which can be programmed into the DMA registers of a peripheral device on the system bus. Note on terminology, (virtual address <-> physical address <-> machine address).

Regards,Olujide
