I have basically built 2.6.35 with make oldconfig from a working 2.6.34.
Latter works fine in kvm while 2.6.35 hangs very early. I see nothing after
grub (have early printk and verbose bootup enabled), just a blinking VGA
cursor and CPU at 100%.
Config is attached. Any ideas what options I could toggle to debug this? I
tried gzip instead of lzma but it isn't that.
Thanks,
Tvrtko

Just discovered I did not removed the quiet boot option, what I thought I
have.. with that removed I see that it hangs just after "Booting the kernel."

Try disabling this as a workaround.

I am in the middle of a bisect run with five builds left to go, currently I
have:

Copying Peter and Borislav, guys please look at the above warning. I am
bisecting a non-bootable 2.6.35 under KVM and while I am not there yet, it is
close to the hweight commit (cb41838bbc4403f7270a94b93a9a0d9fc9c2e7ea) and I
spotted this warning.

That's because you're at a bisection point before the hweight patch but
your .config already contains the ARCH_HWEIGHT_CFLAGS variable because
of the previous bisection point which contained the hweight patch.
I think this can be safely ignored.

Bisect points the finger to "x86, ioapic: In mpparse use mp_register_ioapic"
(cf7500c0ea133d66f8449d86392d83f840102632), so I am copying Eric. No idea
whether this commit is solely to blame or it is a combined interaction with
KVM, but I am sure you guys will know.
If you want me to test something else please shout.

Yep, bisect pointed to another commit so I continued another part of this
thread. Thanks for the explanation!

Interesting. This is the second report I have heard of no VGA output
and a hang early in boot, that was bisected to this commit. Since I
could not reproduce it I was hoping it was a fluke with a single piece
of hardware, but it appears not.
There was in fact an off by one bug in that commit, but if that had
been the issue 2.6.35 would have booted ok. There was nothing in that
commit that should have prevented early output, and in fact I can boot
with a very similar configuration. So I am trying to figure out what
pieces are interacting to cause this failure mode to happen.
What version of kvm are you running on your host (in case that matters)?
I want to reproduce this myself so I can start guessing what weird
interactions are going on.

[PATCH] x86: check if apic/pin is shared with legacy one
fix system that external device that have io apic on apic0/pin(0-15)
also
for the io apic out of order system:
<6>ACPI: IOAPIC (id[0x10] address[0xfecff000] gsi_base[0])

<6>ACPI: IOAPIC (id[0x0e] address[0xfec01000] gsi_base[39])
<6>IOAPIC[2]: apic_id 14, version 0, address 0xfec01000, GSI 39-74

<6>ACPI: INT_SRC_OVR (bus 0 bus_irq 0 global_irq 5 dfl dfl)
<6>ACPI: INT_SRC_OVR (bus 0 bus_irq 3 global_irq 6 dfl dfl)

<6>ACPI: INT_SRC_OVR (bus 0 bus_irq 15 global_irq 18 dfl dfl)
after this patch will get
apic0, pin0, GSI 0: irq 0+75
apic0, pin1, GSI 1: irq 1+75
apic0, pin2, GSI 2: irq 2
apic1, pin0, GSI 3: irq 3+75
apic1, pin5, GSI 8: irq 8+75
apic1, pin10,GSI 13: irq 13+75
apic1, pin11,GSI 14: irq 14+75
because mp_config_acpi_legacy_irqs will put apic0, pin2, irq2 in mp_irqs...
so pin_2_irq_legacy will report 2.
irq_to_gsi will still report 2. so it is right.
gsi_to_irq will report 2.
for 0, 1, 3, 8, 13, 14: still right

Host is stock openSUSE 11.3 with kvm-0.12.3-2.9.x86_64 and kernel-
desktop-2.6.34-12.3.x86_64. Plus a repeat of my .config if it helps.

> Accessing APIC version register before APIC is mapped.
Yep. I see it now. We have some of the silliest code. We only
go down this path for certain revs of Intel cpus, and I double checked
this change on an AMD cpu which explains why I missed hitting this
case.
The call path that is new in they bisected commit is:
MP_ioapic_info()
mp_register_ioapic()
io_apic_unique_id()
io_apic_get_unique_id()
get_physical_broadcast()
modern_apic()
lapic_get_version()
apic_read(APIC_LVR)
Tvrtko can you test this patch and verify it fixes the kvm booting
issue?
This patch just maps the lapic early in the mmparse.c just like we
do in acpi/boot.c when parsing the acpi tables.

Boots fine, thanks!

This fixes a regression in 2.6.35 from 2.6.34, that is
present for select models of Intel cpus when people are
using an MP table.
The commit cf7500c0ea133d66f8449d86392d83f840102632
"x86, ioapic: In mpparse use mp_register_ioapic" started
calling mp_register_ioapic from MP_ioapic_info. An extremely
simple change that was obviously correct. Unfortunately
mp_register_ioapic did just a little more than the previous
hand crafted code and so we gained this call path.
The problem call path is:
MP_ioapic_info()
mp_register_ioapic()
io_apic_unique_id()
io_apic_get_unique_id()
get_physical_broadcast()
modern_apic()
lapic_get_version()
apic_read(APIC_LVR)
Which turned out to be a problem because the local apic
was not mapped, at that point, unlike the similar point
in the ACPI parsing code.
This problem is fixed by mapping the local apic when
parsing the mptable as soon as we reasonably can.
Looking at the number of places we setup the fixmap for
the local apic, I see some serious simplification opportunities.
For the moment except for not duplicating the setting up of the
fixmap in init_apic_mappings, I have not acted on them.
The regression from 2.6.34 is tracked in bug

It is almost the same as smp_register_lapic_addr()
Just need to make smp_read_mpc() call smp_register_lapic_addr when early==1.

x86, apic: Map the local apic when parsing the MP table.
This fixes a regression in 2.6.35 from 2.6.34, that is
present for select models of Intel cpus when people are
using an MP table.
The commit cf7500c0ea133d66f8449d86392d83f840102632
"x86, ioapic: In mpparse use mp_register_ioapic" started
calling mp_register_ioapic from MP_ioapic_info. An extremely
simple change that was obviously correct. Unfortunately
mp_register_ioapic did just a little more than the previous
hand crafted code and so we gained this call path.
The problem call path is:
MP_ioapic_info()
mp_register_ioapic()
io_apic_unique_id()
io_apic_get_unique_id()
get_physical_broadcast()
modern_apic()
lapic_get_version()
apic_read(APIC_LVR)
Which turned out to be a problem because the local apic
was not mapped, at that point, unlike the similar point
in the ACPI parsing code.
This problem is fixed by mapping the local apic when
parsing the mptable as soon as we reasonably can.
Looking at the number of places we setup the fixmap for
the local apic, I see some serious simplification opportunities.
For the moment except for not duplicating the setting up of the
fixmap in init_apic_mappings, I have not acted on them.
The regression from 2.6.34 is tracked in bug

this change is not needed, it will break:
1. found mptable, but is using default contruct path.
2. visws path, found found mptable, but get_smp_conf is not called.

[PATCH] x86: Fix lapic mapping with construct ISA and visws mptable path
do need to set lapic mapping for them
in arch/x86/kernel/visws_quirks.c:
we only have visws_find_smp_config() to set mp_lapic_addr to APIC_DEFAULT_PHYS_BASE
visws_get_smp_config() is nop call.
default_get_smp_config/check_physptr/smp_read_mpc is not called in the path.
So smp_register_lapic_address() is not called, and lapic is not mapped.
in arch/x86/kernel/mpparse.c
if mpf->feature1 != 0, it will go through contruct_default_ISA_mptable instead
of check_phystr path, so smp_register_lapic_address is not called.
those two path all have smp_found_config set.
So let remove !smp_found_config checking
Actually set fixmap two times does not hurt.

YH was saying I overoptimized, and it looks like he is right,
although there are only one or two machines in existence that
are likely to be affected.
Untested patch to remove the cleverness below. It it boots all
is well.

Subject: [PATCH] x86/apic: Always map the local apic in init_apic_mappings.
In all of the common cases we currently map the local apic before
we get to init_apic_mappings. Unfortunately there are still a few
weird subarch code paths that require us to map the local apic in
init_apic_mappings, and those subarchitectures set smp_found_config.
So just unconditionally run the fixmap code, and stop being clever.

no, i don't have those kind of system.
found it when i was preparing more smp_register_lapic_address patcheset.
I suggest we still keep !acpi_lapic checking, that should always right.

I don't know if anyone does. It looks like sfi aka moorestown
and visws are what are affected.
That is why I made a patch that any boot where we exercise a local
apic will exercise.
Arguably if it is best to just remove that hunk from my patch, so
we have something that is safe to backport to 2.6.35.1.

Ultimately we want to remove the code duplication entirely.
