Hi, The current code for KERN_TLS uses PHYS_TO_DMAP() to access unmapped external pages on m_ext.ext_pgs mbufs. I also need to do this to implement RPC-over-TLS.
The problem is that some arches, like i386, don't support PHYS_TO_DMAP(). Since it appears that there will be at most 4 pages on one of these mbufs, my thinking was... - Acquire four pages of kva from the kernel_map during booting. - Then just use pmap_qenter() to fill in the physical page mappings for long enough to copy the data. Does this sound reasonable? Is there a better way?
