Hi all.
I just finished getting a build/run environment for FreeBSD-SMP set up
for my test SMP box (it was a pain in the rear, I'll tell you).
First of all, I tried building the SMP source tree without SMP enabled. The
generic kernel would *not* boot where a normal FreeBSD generic kernel would.
I had to remove a lot of devices to get it to work. The problem was that
after all the devices were probed, it just said:
panic: double fault
syncing disks...
and hung. :-(
The next problem is to note that some presumptions are being made which
aren't good (this is other than I've mentioned before).
-- "APIC_BASE" is *not* a constant. The MPS table will tell the kernel
where it is. Note that all Pentium Pro machines I've tried use a
different address than the one used for Pentium machines (in the
Pentium it was hardwired). This will effect the boot/startup code.
-- The CPU tables (lots of static data) are replicated on the order
of "NCPUS". This will really bloat the static data area. Can
someone comment on what's really needed here ?? Linux used such
a define, but it didn't add a huge amount of overhead.
I have to finish reading through the code... stay tuned! I want to make
quick progress now that I have the environment set up.
