>Description:
I'm unable to boot a -current MP macppc kernel. It initially hits
"autoconfiguration error: 2:CPU 1 didn't start 2", which generates a
brief backtrace at the db prompt. Choosing "continue" after this gets
the boot much farther, but then it starts outputting garbled text at
random points on the console, and reboots.
Note this is not an issue with 8.1. Its GENERIC.MP kernel works quite
well on the same hardware. This is also not an issue with the UP
GENERIC kernel on the same hardware, 8.99.49 works fine (so far as I've
tested it). So there's a regression somewhere in the MP code.
GENERIC.MP kernel with DIAGNOSTIC and DEBUG enabled:

Hmm, this might be fallout from me adding G5 SMP support a while ago,
and unfortunately I don't have a working SMP G4.
IIRC I had to slightly change the way we find the GPIOs that control
each CPU's reset pin ( since of course there are a few differences in
the OF variants used on G5 ) - please send me the ofctl -p output of
your machine, maybe there is something obvious.

This is different than I thought, there are actually two separate
issues involved. The failure to successfully boot an MP kernel can be
duplicated with 8.1_STABLE: when DEBUG and DIAGNOSTIC are enabled, I
get a very similar initial backtrace, and the exact same behaviour
(and, from what I can see, output) before the machine reboots. I hadn't
previously tried a debugging kernel with 8.x, since it otherwise works
fine for me. So this isn't a regression with -current, it's pre-
existing.
With -current, the distinction is a non-debug MP kernel fails to
complete booting. It hangs before running /sbin/init. It continues to
process hardware-related events (e.g., I can unplug and plug in USB
devices, and it continues to handle these correctly), but otherwise
just stalls, without any output to indicate why.
So, perhaps in order to answer why the -current non-debug MP kernel
isn't working, we need to figure out why MP debug kernels aren't
working first.

Hmm, that's a good data point, which narrows things down quite a bit.
Hopefully I'll have time for a closer look on my next weekend ( which
starts Wednesday ).
Yes, this is basically a SIGKEEPALIVE from me.

I tried a couple more things, which didn't really yield that much more.
First, I built an MP debug kernel from the netbsd-7 branch. It also
panics; however, the panic happens later. (It involves a locking issue
with USB devices. If this is unrelated to everything else, I don't
think anyone necessarily wants to chase new issues with 7.x.)
To get around one of the predictable panics with -current, I commented
out
KASSERT(virq != 0);
at line 561 of sys/arch/powerpc/pic/intr.c. This gives me a kernel that
behaves the same as an MP non-debug -current kernel. That is, it
freezes while devices are attaching, after the hard drives have been
recognized. It doesn't seem to output anything significant that's
different from the non-debug kernel.

I finally had a look at the code and the logs - looks like a race
between cpu_setup() on the newly hatched CPU and delay(200000) in
cpu_spinup(), where we just wait a fixed time and then bail out if the
other CPU isn't ready. This would explain why the 2nd CPU still wakes
up later on but then things go south because we didn't install the IPI
handler.
The following patch adds a period of polling h->hatch_running for a
while instead of just blindly increasing the delay().

Hi Michael,
Your patch fixes the initial panic; it now continues booting without
dropping into the debugger, and it doesn't "spontaneously" reboot at
any point. Now the debug and non-debug MP kernels behave identically,
which is that they hang right after USB devices are recognized,
without any output to indicate why. (My debug kernel includes the
DEBUG, DIAGNOSTIC, and LOCKDEBUG options.)
Separately, I've now hit an occasion where 8.1_STABLE without debugging
options also hangs, which I hadn't seen before. It gets farther than
-current: it mounts file systems and tries /sbin/init, and hangs there.
I'm going to try some more tests with it and see what happens.
Thanks,
Dave

Hi Michael,
I can't reproduce that last hanging issue with a non-debug 8.1_STABLE
MP kernel. Every reboot worked without trouble. (Perhaps there's some
rare timing condition involved, or perhaps the hardware is getting
flaky.)
I also tried applying your patch to an 8.1 MP kernel (with DEBUG,
DIAGNOSTIC, and LOCKDEBUG options enabled), and that gets me past the
related original panic there, too. As the 8.1 kernel continues booting,
it gets to the point where it needs to request user input (I have non-
standard partitioning in this test setup), at which point it panics
with the following backtrace:
panic: kernel diagnostic assertion "mutex_owned(&sc->sc_lock)" failed: file "/home/disciple/netbsd-8/src/sys/dev/usb/ohci.c", line 590

(Since -current hangs around USB controller attachment, I wondered if

ohci_device_intr_start() only takes the lock when not polling, so
this assert needs to be adjusted for that.
can you try this patch? it probably won't fix the original hang,
but it should fix this issue. it's against netbsd-8 though i
am fairly sure that the code is the same in -current.

Hi,
Your patch fixed the remaining issue booting an MP+DEBUG+DIAGNOSTIC+
LOCKDEBUG kernel built from the netbsd-8 branch. Thanks!
With this plus macallan@'s earlier patch applied, I don't see any
remaining issues for netbsd-8, so we've narrowed this PR to what's in
HEAD/netbsd-9 now.

great news. i sent a pullup request. i had actually fixed one
of the two chunks back in march, but both are commited now.

i will get the above additional fix into netbsd-9.
can you update us with the status of -current/-9? the system
hangs after probing USB still?
if so and if you can drop to DDB, can you inspect the
"config_pending" variable? eg, "x/x config_pending". if it
is zero, that means that some device configuration has called
config_incr() without a matching config_decr(), which makes the
code that allows mountroot and then init to run to wait. this
is normally for eg, boot device probe, but it tends to indicate
that there is a lack of interupts, allowing a device probe to
complete, but really, anything that stops the driver from
getting to its config_decr() moment will do this.

I built an MP+DEBUG+DIAGNOSTIC+LOCKDEBUG 9.99.7 kernel with the patches
included, and it's hanging after USB devices are attached. I can unplug
and reattach USB devices and it continues to handle those events fine,
but it never actually mounts (or prompts to mount) the hard drive. I
don't see anything useful in the output to indicate why. I'm not able
to get into ddb as far as I know. That is, typing something on the USB
keyboard that's attached doesn't result in anything happening.

does it still have the cpu failure attach messages in early boot?
here's a simple way to see if i'm right about config_pending not
being reduced at this point:
in config_finalize() there is this loop:
while (config_pending != 0)
cv_wait(&config_misc_cv, &config_misc_lock);
if you convert it to a cv_timedwait() that sleeps for hz (or
even hz*2 or hz*5) and then prints config_pending, eg:
while (config_pending != 0) {
cv_timedwait(&config_misc_cv, &config_misc_lock, hz);
printf("%s: config_pending still %d\n", __func__,
config_pending);
}
(untested/compiled). this would at least give us any idea on
where to look next.

The early boot issue with CPU attachment is fixed.

I have serial console though and can get into ddb.

I tried a build of 9.99.17 from earlier this week, and the situation
has improved. It no longer hits any issues during device attachment,
and begins running rc scripts. At that point, however, as it's bringing
up the gem0 device, it panics there, like so:
