source: soft/giet_vm/sys/drivers.h @ 255

Last change on this file since 255 was 255, checked in by meunier, 11 years ago
Added a syscall and some user functions to manipulate the Simulation Helper Changed the the way the Vseg -> Pseg mapping is made during the boot to better utilize the address space (+ adaptation of the algorithm in memo) Fixed a bug in boot_init (vobj_init): the vobj initialization could only be made for the first application (ptpr was not changed)
