Function Documentation

t_pgset* bigalloc (  asid_t  asid, int  nb_pgs )

allocate a huge virtual zone composed of many small physical zones

void bigdump (  t_pgset *  set  )

debug

int bigfree (  t_pgset *  set  )

vaddr_t pgalloc (  asid_t  asid, int  nb_pgs )

alloc phys pages + vpages and vmap them

vaddr_t pgalloc2 (  asid_t  asid, paddr_t  fixed_pa, int  nb_pgs, paddr_t *  pa_returned )

same thing as pgalloc(3) excepted that it is possible to specify a fixed paddr and also retrieve physical addr choosem. pa_returned might be NULL.

int pgfree (  asid_t  asid, vaddr_t  vpages, int  nb_pgs )

int ppgalloc (  asid_t  asid, int  nb_pgs, paddr_t *  pa_returned, int *  nb_pgs_returned )

try to alloc nb_pgs or less
