X2APIC has never worked on this system, and continues to not work
3.2.0-rc5. Simply hangs on boot with an error message that helpfully
indicates that x2apic is the problem. The system is an ASRock P67
Extreme 6. Log attached, let me know if I can do anything to help.

your bios should not enable x2apic in this case.
please get one bios update.
also I have one old patch that could disable apic. but it is not get
merged and it may not be applied to current tree.
let us know if you can not get BIOS update or can not disable x2apic
in BIOS setup.
Thanks

Subject: [PATCH -v3] x86: Disable x2apic if nox2apic is specified
For
1. x2apic preenabled system
2. first kernel have x2apic enabled, and try to kexec second kernel with "nox2apic"
Will put back cpu with apic id < 255 into xapic mode, instead of panic.
-v2: use x2apic_disabled instead of nox2apic, Suggested by Thomas
update x2apic_supported with x2apic_disabled, Suggested by Thomas
-v3: add checking for boot cpu apic id > 255. in that case will just panic
--- pointed out by Suresh.

I am, in fact, able to disable x2apic in the BIOS and it works fine. I
was just under the impression that x2apic should be available and should
work? Is this wrong? If so, then there's no kernel bug, and I just
misunderstood.

it's not kernel bug.
BIOS need to provide DMAR table, so kernel could enable
intr-rempapping, and x2apic need intr-remap.
Thanks

What we want is not a nox2apic option but a good fall-back
mechanism that is able to boot the system automatically and
safely, without the user having to tweak *anything* ...

Sure.
Attached -v4 should automatically switch to xapic mode.
Berck,
Can you please try -v4 patch on your setup when BIOS have x2apic enabled?
Thanks
Yinghai Lu
[-- Attachment #2: nox2apic_v4.patch --]
[-- Type: text/x-patch, Size: 10202 bytes --]
Subject: [PATCH -v4] x86: Disable x2apic if nox2apic is specified or intr-remap can not be enabled
For
1. x2apic preenabled system
2. first kernel have x2apic enabled, and try to kexec second kernel with "nox2apic"
Will put back cpu with apic id < 255 into xapic mode, instead of panic.
-v2: use x2apic_disabled instead of nox2apic, Suggested by Thomas
update x2apic_supported with x2apic_disabled, Suggested by Thomas
-v3: add checking for boot cpu apic id > 255. in that case will just panic
--- pointed out by Suresh.
-v4: according to Ingo, for x2apic pre-enabled system, if intr-remap can not
be enabled, try to disable x2apic instead of panic and request to
specify nox2apic for next boot.

x2apic pre-enabled skip the mapping for lapic address. so need map it
after fall back.
please check attached -v5..

Subject: [PATCH -v5] x86: Disable x2apic if nox2apic is specified or intr-remap can not be enabled
For
1. x2apic preenabled system
2. first kernel have x2apic enabled, and try to kexec second kernel with "nox2apic"
Will put back cpu with apic id < 255 into xapic mode, instead of panic.
-v2: use x2apic_disabled instead of nox2apic, Suggested by Thomas
update x2apic_supported with x2apic_disabled, Suggested by Thomas
-v3: add checking for boot cpu apic id > 255. in that case will just panic
--- pointed out by Suresh.
-v4: according to Ingo, for x2apic pre-enabled system, if intr-remap can not
be enabled, try to disable x2apic instead of panic and request to
specify nox2apic for next boot.
-v5: fix the lapic mapping for falling path.

If bios has not exported any DMAR tables but enabled x2apic pre-boot, it
is tricky for the OS to disable x2apic and continue with xapic for
number of reasons. For example, if chipset has already enabled
interrupt-remapping (which is typically recommended to be enabled before
x2apic) but didn't provide DMAR tables, then there is no way OS can
disable interrupt-remapping in this case.
So even though the cpu might be back in xapic mode, but external
interrupts won't work.
thanks,
suresh

It appears to work correctly as far as I can tell.

This is ugly. Typically we have no- for boolean options. If we have a
multivalue option it should be option=value, i.e. x2apic=disabled. We
can allow x2apic_supported as a backwards compatibility option.

Ok. In this case, it looks like bios didn't enable interrupt-remapping
(part of vt-d) and just enabled x2apic with out touching or exporting
vt-d HW.
Yinghai, In other scenarios where OS can't recover, mostly likely we
will fail in check_timer() when we fall back to xapic. Can we add a
printk in this case to convey the potential reason (that I mentioned in
the previous e-mail), so that the user can get more accurate information
for the check timer failure.
thanks,
suresh

x2apic_disabled is variable.
for command line, still use nox2apic for that purpose.

agree. in that case, will have problem.
but i don't think bios buy can go that far to enable intr-remapping
without providing DMAR.
will check if can add print out in check_timer() when
x2apic_preenabled == 1 and x2apic == 0...

We never know. And also It is not just bios. kexec'd kernel with out the
interrupt-remapping support will also run into this issue and we should
handle this also gracefully.

please check attached -v6 with print out as you requested.

[-- Type: text/x-patch, Size: 11313 bytes --]
Subject: [PATCH -v6] x86: Disable x2apic if nox2apic is specified or intr-remap can not be enabled
For
1. x2apic preenabled system
2. first kernel have x2apic enabled, and try to kexec second kernel with "nox2apic"
Will put back cpu with apic id < 255 into xapic mode, instead of panic.
-v2: use variable x2apic_disabled instead of variable nox2apic, Suggested by Thomas
update x2apic_supported with x2apic_disabled, Suggested by Thomas
-v3: add checking for boot cpu apic id > 255. in that case will just panic
--- pointed out by Suresh.
-v4: according to Ingo, for x2apic pre-enabled system, if intr-remap can not
be enabled, try to disable x2apic instead of panic and request to
specify nox2apic for next boot.
-v5: fix the lapic mapping for falling path.
-v6: add warning when check_timer fails in strange case when BIOS enable x2apic
and intr_remapping but does not provide dmar table. requested by Suresh.

Subject: [PATCH -v7] x86: Disable x2apic if nox2apic is specified or intr-remap can not be enabled
For
1. x2apic preenabled system
2. first kernel have x2apic enabled, and try to kexec second kernel with "nox2apic"
Will put back cpu with apic id < 255 into xapic mode, instead of panic.
-v2: use variable x2apic_disabled instead of variable nox2apic, Suggested by Thomas
update x2apic_supported with x2apic_disabled, Suggested by Thomas
-v3: add checking for boot cpu apic id > 255. in that case will just panic
--- pointed out by Suresh.
-v4: according to Ingo, for x2apic pre-enabled system, if intr-remap can not
be enabled, try to disable x2apic instead of panic and request to
specify nox2apic for next boot.
-v5: fix the lapic mapping for falling path.
-v6: add warning when check_timer fails in strange case when BIOS enable x2apic
and intr_remapping but does not provide dmar table. requested by Suresh.
-v7: fix compiling with x2apic_preenabled

That's interesting.
Now if this could be made completely automatic (no extra
parameter passing), then we have a usable fallback mode - which
is preferred to crashing the box.
Thanks,

yes. Yinghai, if you remember you had a T420 that didn't show the
problem. And someone in the bugzilla with T420 had the problem. And
their dmidecode is
https://launchpadlibrarian.net/109393850/dmidecode.txt
What is the difference with your system? Bios I think is the same.
Can you see what we should check for in the dmi tables to black list
these systems? Can you post your T420's dmidecode to see the difference.
Bugs I have on this are:

I think his system has DMAR table and cpu support x2apic, So kernel
will switch to x2apic,
but somehow BIOS SMI handler has problem with x2apic. should be thinkpad W520?

commit fb209bd891645bb87b9618b724f0b4928e0df3de

x86, x2apic: Fallback to xapic when BIOS doesn't setup interrupt-remapping
On some of the recent Intel SNB platforms, by default bios is pre-enabling
x2apic mode in the cpu with out setting up interrupt-remapping.
This case was resulting in the kernel to panic as the cpu is already in
x2apic mode but the OS was not able to enable interrupt-remapping (which
is a pre-req for using x2apic capability).
On these platforms all the apic-ids are < 255 and the kernel can fallback to
xapic mode if the bios has not enabled interrupt-remapping (which is
mostly the case if the bios has not exported interrupt-remapping tables to the
OS).

Any update? The messages just seem to have stopped months ago. A fallback would be nice, I have been booting the kernel with noa2xpic for since kernel 3.2, and currently I am working with 3.6.2.
If needed I can try to attempt modifying the patch to include fallback, but I am probably not the best person to do it.

X2APIC has never worked on this system, and continues to not work
3.2.0-rc5. Simply hangs on boot with an error message that helpfully
indicates that x2apic is the problem. The system is an ASRock P67
Extreme 6. Log attached, let me know if I can do anything to help.
Please cc as I'm not subscribed.
