Hi! gurus,
I have a special requirement by which i need atleast 512kb of
contigous physical memory in SPARC.
The functions like kmem_alloc are returning 8kb pages and does not
guarantee contiguos physical memory.
I am trying now to use dma functions. But from the old postings in
this group and from the Solaris driver man pages it seems to me that
dma functions also does not gurantee contiguos physical memory.
It would be greatly helpful to me if somebody can give some pointers
on how this can be achieved.
regards,
Anoop
