Is anyone running a NetBSD 1.6 ppc port using more than 256Mb of
physical memory?
It looks like the "oldpmap" code asummes all of physical memory fits in
(is mapped by) KERNEL_SR, while the newer code dosn't seem to allow more
than a segement of KVA
either.(although the walnut code apparently does). I run out KVA trying
to map buffers, although I havn't investigated as to exactly why. Is
KERNEL_SR still used for copyin/out? Why wouldn't the first 256 be
allocated 1/1 using bat[0]?
