Changes since last time:
- INSTALL.MP floppy kernel is no longer stripped so tracebacks
will be more comprehensible
- I/O interrupts should work if the boot cpu is not at apic id 0.
- the presence of an EISA bus should not cause an immediate
panic while processing interrupt routing information.
Note that I have no idea if the EISA interrupt routing code
I wrote actually *works*, as I have no hardware to test it on..
- "locking against myself" warning message from msdosfs is
- PCMCIA/cardbus interrupt disestablish still doesn't work.
Reported problems not yet investigated:
- panic: apic_vectorset: no free vectors
seen by one person.
- cpu failed to become ready errors
(seen on two or three systems).
the kernel will drop into DDB at this point; you can
continue (c), but this is an indication that the other
CPU failed to start.
- one system reported an I/O APIC at APIC ID 16, which is an
ioapic0 at mainbus0 apid 16 (I/O APIC)
ioapic0: duplicate apic id (ignored)
panic: can't deal with all-ioapics interrupt yet!
In that directory, you'll find several test kernels and a boot floppy
image set containing the currently HIGHLY EXPERIMENTAL x86
multiprocessor spinup support. If you attempt to put these into
production use, I'll laugh at you.
netbsd-GENERIC.MP GENERIC.MP kernel, for booting on systems
which already have NetBSD installed.
netbsd-INSTALL.MP compressed INSTALL.MP kernel with install miniroot.
netbsd-HYDRA Kernel for my ABIT BP6-based development machine.
boot1.fs boot floppy image (1/2)
boot2.fs boot floppy image (2/2)
Please send reports of how far these manage to boot on your systems to
firstname.lastname@example.org and/or email@example.com.
dmesg output from a successful boot (or an unsuccessful boot, for that
matter) would be appreciated; probably the best way to capture dmesg
output frmo an unsuccessful boot is by hooking up a serial console and
using serial bootblocks. a future round may include alternate boot
floppy images with serial bootblocks to make this easier.
