Yes I got that. Hopefully the secondary virtual address mapping you are referring to would be the process address space mapping. Just for testing and making it act like I have mmap'd system RAM I have assigned kernel linear addresses to by doing a char *ch = (char *)kmap(pgmem = pfn_to_page(vma->vm_pgoff); setting a value "TEST" and reading it in the userspace process after mmap'ing the physical range. Also I can map different process address space to the same physical page frame right? _______________________________________________ Kernelnewbies mailing list Kernelnewbies@xxxxxxxxxxxxxxxxx http://lists.kernelnewbies.org/mailman/listinfo/kernelnewbies
