[PATCH 0/2] x86, apic: Disable BSP if boot cpu is AP

[HATAYAMA Daisuke]

This is the patch series to address the issue that kdump 2nd kernel
now fails to wake up multiple CPUs.

This is based on 3.11-rc7.

I tested this patch series on x86. I used 2 cpus by specifying
nr_cpus=2 for the 2nd kernel. I checked both ACPI MADT and MP table
case; the former is default on my system and for the latter I did
acpi=off. I crashed the system both on BSP and AP by taskset -c {0,1}
sh -c "echo c > /proc/sysrq-trigger".

[PATCH 2/2] x86, apic: Disable BSP if boot cpu is AP

[HATAYAMA Daisuke]

Currently, on x86 architecture, if crash happens on AP in the kdump
1st kernel, the 2nd kernel fails to wake up multiple CPUs. The typical
behaviour we actually see is immediate system reset or hang.

This comes from the hardware specification that the processor with BSP
flag is jumped at BIOS init code when receiving INIT; the behaviour we
then see depends on the init code.

This never happens if we use only one cpu in the 2nd kernel. So, we
have avoided the issue by the workaround that specifying maxcpus=1 or
nr_cpus=1 in kernel parameter of the 2nd kernel.

In order to address the issue, this patch disables BSP if boot cpu is
AP. Then, there's no longer the BSP. There's no longer possibility to
send INIT to the BSP.

Before this idea we discussed the following two ideas but we cannot
adopt them in each reasons:

  1. Switch CPU from AP to BSP via IPI NMI at crash in the 1st kernel

    This is done in the kdump crash path where logic is in
    inconsistent state. Any part of memory can be corrupted, including
    hardware-related table being accessed for example when paging is
    performed or interruption is performed.

  2. Unset BSP flag of the boot cpu in the 1st kernel

    Unsetting BSP flag can affect some real world firmware badly. For
    example, Ma verified that some HP systems fail to reboot under
    this configuration. See:
    http://lkml.indiana.edu/hypermail/linux/kernel/1308.1/03574.html

Due to the idea 1, we have to address the issue in the 2nd kernel on
AP. Then, it's impossible to know which CPU is BSP by rdmsr
instruction because the CPU is the one we are now trying to wake
up. From the same reason, it's also impossible to unset BSP flag of
the BSP by wrmsr instruction.

Next, due to the idea 2, BSP is halting in the 1st kernel while
keeping BSP flag set (or possibly could be running somewhere in
catastrophic state.) In generall, CPUs except for the boot cpu in the
2nd kernel -- the cpu under which crash happened --- can be thought of
as remaining in any inconsistent state in the 1st kernel. For APs,
it's possible to recover sane state by initiating INIT to them; see
3.7.3 Processor-specific INIT in MultiProcessor
specification. However, there's no way for BSP. Therefore, there's no
other way to disable BSP.

My motivation is to generate crash dump quickly on the system with
huge memory. We can assume such system also has a lot of N-cpus and
(N-1)-cpus are still available.

To identify which CPU is BSP, we lookup ACPI table or MP table. One
concern is that ACPI guidlines BIOS *should* list the BSP in the first
MADT LAPIC entry; not *must*. In this sense, this logic relis on BIOS
following ACPI's guideline. On the other hand, we don't need to worry
about this in MP table case because it has explit BSP flag.

To avoid any undesirable bahaviour caused by any broken BIOS that
doesn't conform to the guideline, it's enough to limit the number of
cpus to 1 by specifying maxcpu=1 or nr_cpus=1, as is currently done in
default kdump configuration. (But of course, it's problematic in
maxcpu=1 case if trying to wake up other cpus later in user space.)

SFI and devicetree doesn't provide BSP information, so there's no
functionality change in their codes, only assigning false for all the
entries, keeping interface uniform.

[PATCH 2/2] x86, apic: Disable BSP if boot cpu is AP

[HATAYAMA Daisuke]

Currently, on x86 architecture, if crash happens on AP in the kdump
1st kernel, the 2nd kernel fails to wake up multiple CPUs. The typical
behaviour we actually see is immediate system reset or hang.

This comes from the hardware specification that the processor with BSP
flag is jumped at BIOS init code when receiving INIT; the behaviour we
then see depends on the init code.

This never happens if we use only one cpu in the 2nd kernel. So, we
have avoided the issue by the workaround that specifying maxcpus=1 or
nr_cpus=1 in kernel parameter of the 2nd kernel.

In order to address the issue, this patch disables BSP if boot cpu is
AP. Then, there's no longer the BSP. There's no longer possibility to
send INIT to the BSP.

Before this idea we discussed the following two ideas but we cannot
adopt them in each reasons:

  1. Switch CPU from AP to BSP via IPI NMI at crash in the 1st kernel

    This is done in the kdump crash path where logic is in
    inconsistent state. Any part of memory can be corrupted, including
    hardware-related table being accessed for example when paging is
    performed or interruption is performed.

  2. Unset BSP flag of the boot cpu in the 1st kernel

    Unsetting BSP flag can affect some real world firmware badly. For
    example, Ma verified that some HP systems fail to reboot under
    this configuration. See:

Due to the idea 1, we have to address the issue in the 2nd kernel on
AP. Then, it's impossible to know which CPU is BSP by rdmsr
instruction because the CPU is the one we are now trying to wake

the BSP by wrmsr instruction.

Next, due to the idea 2, BSP is halting in the 1st kernel while
keeping BSP flag set (or possibly could be running somewhere in
catastrophic state.) In generall, CPUs except for the boot cpu in the
2nd kernel -- the cpu under which crash happened --- can be thought of
as remaining in any inconsistent state in the 1st kernel. For APs,
it's possible to recover sane state by initiating INIT to them; see
3.7.3 Processor-specific INIT in MultiProcessor
specification. However, there's no way for BSP. Therefore, there's no
other way to disable BSP.

My motivation is to generate crash dump quickly on the system with
huge memory. We can assume such system also has a lot of N-cpus and
(N-1)-cpus are still available.

To identify which CPU is BSP, we lookup ACPI table or MP table. One
concern is that ACPI guidlines BIOS *should* list the BSP in the first
MADT LAPIC entry; not *must*. In this sense, this logic relis on BIOS
following ACPI's guideline. On the other hand, we don't need to worry
about this in MP table case because it has explit BSP flag.

To avoid any undesirable bahaviour caused by any broken BIOS that
doesn't conform to the guideline, it's enough to limit the number of
cpus to 1 by specifying maxcpu=1 or nr_cpus=1, as is currently done in
default kdump configuration. (But of course, it's problematic in
maxcpu=1 case if trying to wake up other cpus later in user space.)

SFI and devicetree doesn't provide BSP information, so there's no
functionality change in their codes, only assigning false for all the
entries, keeping interface uniform.

This variable naming looks confusing, IMHO. It would probably be more
understandable if 'isbsp' was called 'boot_cpu' to denote that this is
the CPU we're booting on currently. The comment above it then explains
that it is an AP and it might also refer to the issue why we're doing
that.

Visible comment, so needs a bit of correcting:

Thanks for your reviewing.

Yes, primary reason of disabling BSP is to avoid hang/reset in the kdump
2nd kernel. Saving memory is the secondary merit compared with
the user-space workaround by specifying nr_cpus=1 or maxcpus=1 and
waking up APs later except for the BSP. I will not write this in the
next version.

As you suggest, boot_cpu seems more understandable also to me. BTW, please
notice that it doesn't denote that the CPU we're booting on currently,
but that the CPU with BSP flag set.

In general, current code uses many terms to denote the cpu that is run
at kernel boot-up processing such as boot cpu, bsp, cpu0 and possibly others
since in usual situation, boot cpu is always BSP and assigned to cpu0.
But it is not the case in case of kexec. I'm using the word bsp purposely
in the isbsp to mean the CPU with BSP flag set.

So I think it's better to use bsp_cpu here to denote the CPU with BSP flag set.

For the comment, how about the following one?

Hmm, by "BSP flag set" you mean it is the first LAPIC entry in the MADT,
correct? At least this is the case when you set isbsp to true. Because,
there's also the BSC flag in APIC_BAR (MSR 0x1b) which denotes the
bootstrapping core on node 0.

Yes, much better. Especially when looking down the road and people have

Yes, much better. Especially when looking down the road and people have
forgotten what the whole fuss was about, a nice detailed comment is
priceless.

The reason why I don't lookup BSP flag in MSR is that it's impossible.
To read MSR of some CPU, we need to use rdmsr instruction on the CPU.
However, in case of this issue, the BSP is halting or running in
the kdump 1st kernel.

A whole explanation is written in the patch description.

Yes, and on the AP, that flag would be cleared which makes it not a BSP.

Those tend to get lost in git history when a bunch of whitespace jerk
offs appear ontop. So a nicely written comment in the code could be very
helpful.

Yes, that's the point this patch series misses. I'll describe the explanation

x86, apic: Disable BSP if boot cpu is AP

Currently, on x86 architecture, if crash happens on AP in the kdump
1st kernel, the 2nd kernel fails to wake up multiple CPUs. The typical
behaviour we actually see is immediate system reset or hang.

This comes from the hardware specification that the processor with BSP
flag is jumped at BIOS init code when receiving INIT; the behaviour we
then see depends on the init code.

This never happens if we use only one cpu in the 2nd kernel. So, we
have avoided the issue by the workaround that specifying maxcpus=1 or
nr_cpus=1 in kernel parameter of the 2nd kernel.

In order to address the issue, this patch disables BSP if boot cpu is
an AP, and thus we don't try to wake up the BSP by sending INIT.

Before this idea we discussed the following two ideas but we cannot
adopt them in each reasons:

  1. Switch CPU from AP to BSP via IPI NMI at crash in the 1st kernel

    This is done in the kdump crash path where logic is in
    inconsistent state. Any part of memory can be corrupted, including
    hardware-related table being accessed for example when paging is
    performed or interruption is performed.

  2. Unset BSP flag of the boot cpu in the 1st kernel

    Unsetting BSP flag can affect some real world firmware badly. For
    example, Ma verified that some HP systems fail to reboot under
    this configuration. See:
    http://lkml.indiana.edu/hypermail/linux/kernel/1308.1/03574.html

Due to the idea 1, we have to address the issue in the 2nd kernel on
AP. Then, it's impossible to know which CPU is BSP by rdmsr
instruction because the CPU is the one we are now trying to wake
up. From the same reason, it's also impossible to unset BSP flag of
the BSP by wrmsr instruction.

Next, due to the idea 2, BSP is halting in the 1st kernel while
keeping BSP flag set (or possibly could be running somewhere in
catastrophic state.) In generall, CPUs except for the boot cpu in the
2nd kernel -- the cpu under which crash happened --- can be thought of
as remaining in any inconsistent state in the 1st kernel. For APs,
it's possible to recover sane state by initiating INIT to them; see
3.7.3 Processor-specific INIT in MultiProcessor
specification. However, there's no way for BSP. Therefore, there's no
other way to disable BSP.

My motivation is to generate crash dump quickly on the system with
huge memory. We can assume such system also has a lot of N-cpus and
(N-1)-cpus are still available.

To identify which CPU is BSP, we lookup ACPI table or MP table. One
concern is that ACPI guidlines BIOS *should* list the BSP in the first
MADT LAPIC entry; not *must*. In this sense, this logic relis on BIOS
following ACPI's guideline. On the other hand, we don't need to worry
about this in MP table case because it has explit BSP flag.

To avoid any undesirable bahaviour caused by any broken BIOS that
doesn't conform to the guideline, it's enough to limit the number of
cpus to 1 by specifying maxcpu=1 or nr_cpus=1, as is currently done in
default kdump configuration. (But of course, it's problematic in
maxcpu=1 case if trying to wake up other cpus later in user space.)

SFI and devicetree doesn't provide BSP information, so there's no
functionality change in their codes, only assigning false for all the
entries, keeping interface uniform.

[ hpa: it might be better in the future for the primary kernel to
  explicitly export the APIC ID for the BSP.  The primary kernel will
  know, both due to which CPU it was booted from and because it can
  see the BSP flag.  However, this seems like a net win for now. ]

This patch seems to trigger build failures in some configurations.
Specifically:

(.init.text+0x1307): undefined reference to `boot_cpu_is_bsp_init'

Unfortunately I don't have the specific configuration which triggers the
failure, as this was discovered by Fengguang's robot.

I have triggered that too and have such a config, it's attached.

Okay, thinking about this again, this patchset is in fact broken on:

1. Any configuration which has CONFIG_SMP=n and CONFIG_X86_UP_APIC=n.

This is a built-time problem.

2. Any CPU which is old enough that MSR_IA32_APICBASE doesn't exist.

This is a fatal runtime bug.

3. Any clustered solution which involves a third-party cluster
controller such that MSR_IA32_APICBASE may not reflect the reality of
the system.

This is a less critical issue as "all" it ought to make happen is to
disable some CPUs which didn't need it.

Hatayama-san, you got this build bug report almost a month ago.  It
looks like it is going to need a fair bit of cleanup, so I fear this is
going to be dropped for v3.13.

Thanks for pointing out that. I think the first two issues has already been
fixed in v3 version. I've just posted v5 version a little time ago. BTW,
I changed the basic design at v4 where we specify the initial APIC ID of the
processor we want to disable in the kdump 2nd kernel from the the 1st kernel
through newly introduced disable_cpu_apicid kernel parameter; it might be
similar to the idea you described in the patch description of tip tree.

I don't know the third issue. Could you explain what kind of things can happen
on clustered system? Only IA32_APIC_BASE MSR is no longer trusted? Or are
there other things we can possibly no longer trust?

Also, could you explain what you suggest to deal with the issue in more detail?

Thanks.

OK, I see now.  It looks like it was radically changed, so the branch in
the -tip tree is completely stale.

On a clustered system, the CPU APICIDs will duplicate, as only a
hardware-specific method can obtain the cluster-wide ID.  That is why we
have struct apic.get_apic_id().

IA32_APIC_BASE_MSR is another matter... it doesn't even exist on older
hardware.  It might be as simple as if IA32_APIC_BASE_MSR doesn't exist
we ignore this whole mechanism (this applies to P5 and earlier, but also
modern derivatives like Quark) but we can't blindly touch this register
as it might trap.  At the very least it needs to be rdmsr_safe().

I think the only thing we can do is to record in the first kernel on
which CPU we were booted on.  Then there is no need to look at the BSP
flag in APIC_BASE_MSR at all or anything similar.

Please explain the "now" in the above sentence.  Is this a regression?
If so, what is its impact?  Is this something that needs to go into 3.11
as a post-rc7 change, which means it better be hyper-critical?

This is not a regression.

No.  This is something that does not need to go into 3.11.

This situation is people who run machines of unreasonable size really
would like to use multiple cpus when generating crash dumps.  A
practical problem with that desire is that sending a (startup? init? I
forget which) IPI to a processor with the BSP flag sent triggers that
processor to load code from 0xfffffff0 instead of the vector specified
in the IPI.  At which point the processor which jumped to 0xfffffff0 and
is running BIOS code does not call into the kernel so never comes up
which is unfortunate, and worse almost always triggers a soft reset by
writing hardware registers.

Which means the practical way to avoid this sort of thing is not to send
init/startup IPIs to processors with the BSP bit set.  Which MPtables
and ACPI tables should denote as the boot processor.

In a previous attack on this problem we explored if it was possible to
clear the BSP bit and be able to use all processors but that does not
work.  I think it was actually your suggestion that we just skip the
BSP.

Anyway this long simmering issue has raised it's head again and we have
iron-clad evidence that the only thing people can do is avoid the
problem so this is a patchset to allow people who wind up in a
situtation where they are not booting on the bootstrap processor to to
avoid problems, and use as many of their other processors as possible.

Which should make people with boxes of unusual size happy.

situtation where they are not booting on the bootstrap processor to to
avoid problems, and use as many of their other processors as possible.

Which should make people with boxes of unusual size happy.

Yes. Now kdump is in a phase where people are doing scalability work. And
one of the problems is that on mutli tera byte machines, filtering is
taking long time. With-in filtering it is especially the compression which
takes the longest (hatayama and cliff wickman have done some study here).

So Idea seems to be that bring up more cpus in the second kernel and try
to parallelize compression work and try to save dump time of multi tera
byte machines.

Thanks

This is not a regression just as Eric explains.

There is also my explanation in the description of the 2nd patch. I should have described so here explicitly.

OK.  We're probably days away from a merge window, so I would like to
put this in the queue for 3.13.

Hi hpa,

Have you queued up these patches for 3.13?

Thanks

Yeah, I'm also interested. But I think we were waiting for HATAYAMA
Daisuke to send a cleaned up version of the patch set.

@HATAYAMA: If you're too busy to clean up the series, I can do that for
you and re-send it here. But I don't want to "steal" the work from you.
