If I _had_ to pick an arch on which to learn how this stuff works, it probably
would not have been vax... unless of course I was experimenting with time
compressing drugs. If we have a 1.4.2, this is definitely a candidate.
missing pte's, instead map in pte entries in pmap_enter(). The user ptes
is no more handled by the VM system. All this made swapping start working
on VAX again.
Still to do:
- Keep refcount per pte page, so that those pages get free'd when the
process is swapped out. Right now they are only free'd when the pmap
is destroyed.
Many thanks to Chuck Silvers for all help finding the deadlock problems.
- fix emitrules() like emitfiles() to deal with the prefix (otherwise it
would attempt to find the file in the normal base for the NORMAL_C rule).
- add emitincludes() which adds include directives for each prefix to the
$INCLUDES variable in the makefile.
- add %INCLUDES to each Makefile.arch to deal with the above.
this makes "prefix" actually work in a usable manner, and now i can move
on to fixing compiler warnings (errors) in the ESP code. :)
Not doing this caused packets to be read into memory somewhere after the
kernel was started but before the device was probed, normally in the
system page table. This gave quite unpredictable results...
- remove "need-flag" for mac68k esp driver, as it is not used in anywhere
and conflicts with IPsec ESP header.
This should be the only MD change in IPv6 support, except kernel config file.
Very sorry if you have any compilation problem with it (I believe it is okay).
If your favorite arch is not included in here, please add a
call to ip6intr() from softintr handle.
has PAGEABLE and INTRSAFE flags. PAGEABLE now really means "pageable",
not "allocate vm_map_entry's from non-static pool", so update all map
creations to reflect that. INTRSAFE maps are maps that are used in
interrupt context (e.g. kmem_map, mb_map), and thus use the static
map entry pool (XXX as does kernel_map, for now). This will eventually
change now these maps are locked, as well.
