This cleanly reserves the lower half -of the virtual address space for userspace applications. - -The -.Ft PHYS_TO_VIRT -macro converts a kernel physical address to a higher half -virtual address. - -The -.Ft VIRT_TO_PHYS -macro converts a higher half virtual address to a kernel -physical address. - -.Sh AUTHORS -.An Ian Moffett Aq Mt ian@osmora.org - -.Sh SEE ALSO -.Xr dynalloc 9 -.Xr pmap 9 |
