[PATCH 1/2] x86: fix keeping track of AMD C1E

[Michal Schmidt]

On my system with AMD Phenom II X6 I am seeing pauses at boot (usually during
udev startup) which require a key press to continue. It only happens if C1E is
enabled in the BIOS.

It's caused by the APIC timer's inability to wake up the CPU from C1E (AMD
erratum #400). Linux has a workaround for it, but it's not being applied
correctly in this case. Though c1e_idle() detects C1E just fine, by the time
acpi_idle ('processor.ko' module) takes over, it is forgotten.

After AMD C1E is detected, it is not sufficient to flag it in boot_cpu_data,
because the flag will get cleared in identify_cpu() when more CPUs are brought
up later. The fix is to mark the flag as forced.

The additional call to set_cpu_cap() is just to make sure the flag is set even
on the CPUs that are already up and /proc/cpuinfo shows 'amdc1e' on all.

Also fix indentation in the function.

Yeah, I was staring at it already. And it looks ok at a first glance.
However, since you want to speed it up into urgent, I'd like to give it
a run at our X6 boxes tomorrow before ACKing it..

... and this is strange, I didn't experience anything like that on our
X6 boxes here couple of months ago. But maybe something got changed in
later kernels to trigger that behavior. Michal, what chipset is that and
do you have the latest BIOS on it?

I don't think that the workaround is wrong, assuming I'm not missing
something. I'm seeing the following sequence on my machine here in which
the cores are brought up and checked for c1e:

The BSP does

start_kernel()
|->check_bugs()
   |->identify_boot_cpu() 	# here we do select_idle_routine(), i.e. pm_idle = c1e_idle
...
|->rest_init()
   |->kernel_thread(kernel_init,... )

and kernel_init() does smp_init() where we init the rest of the cores.

Now, each core does

start_secondary()
|->smp_callin()
   |->smp_store_cpu_info	# here we copy boot_cpu_data for the starting AP
     |->identify_secondary_cpu
        |->identify_cpu
	   |->select_idle_routine() # here we exit early since pm_idle is set already


now all the cores except the BSP do cpu_idle but since bits 27,28 in the
int pending MSR (see below) are not set yet, they spin a bit in cpu_idle
doing default_idle. You can see this with my debugging patch below.

Now here comes the key moment - the BSP enters cpu_idle _after_ all APs
have been initialized and does set X86_FEATURE_AMDC1E. We haven't set
the c1e_detected variable earlier since the hardware sets bit 28 in
MSR_K8_INT_PENDING_MSG, C1eOnCmpHalt only after all cores have entered
halt. After this bit is set, we set c1e_detected and switch to broadcast
mode on each core.

Now the question is, why does your system doesn't do that in that order?
And I don't think your patch is the right fix - it doesn't change
anything in the above sequence on my system except enabling the "amdc1e"
feature string in /proc/cpuinfo which we don't need actually since dmesg
already contains that info.

And the more puzzling question is, how does your patch fix your
system...?

So, IMHO, what is more likely is that it has something to do with
https://bugzilla.kernel.org/show_bug.cgi?id=15289, as John pointed out
earlier (thanks John, Michal's situation looks quite similar).

So, please apply the debug patch below and send me your whole dmesg to
see what happens. Also, I'd like to see whether the SMI bit (27) in that
same MSR is set so please do when the machine is up

for i in $(seq 0 5); do lsmsr -c $i Int -V 3; done

after installing the x86info tool.

Thanks.

On my system I see bit 28 set right at the start. Is it a BIOS bug?
Your debugging patch produces a huge flood of messages, seemingly
neverending.

I would not bother using the patch if the only result would be showing
of the "amdc1e" misfeature string in /proc/cpuinfo :-)

It makes sure that once "boot_cpu_has(X86_FEATURE_AMDC1E)" is true, it
won't ever become false.
To see what I mean see the dmesg I've got with a bit different debugging

This suggests that another way to fix my problem would be this (tested):

Ok, there is a difference in how the BIOS sets bit 28. But this version
of the fix should take care of both cases as it works on my machine too.
You could also add this hunk to your patch:

so that we get rid of that simulated CPUID flag completely and use
c1e_detected only.

I'll test it on my other AMD boxes to make sure we don't regress on
older machines...

Thanks.

You mean the c1e_detected variable and the CPUID flag, right? Well,
frankly and if I'm not missing anything, we actually only need to track
when either bits [27,28] get set in that MSR - MSR_K8_INT_PENDING_MSG -
in order to do timer broadcast.

And strictly speaking, we don't need a variable for that at all (nor a
synthetic CPUID flag, for that matter) - we can simply read the MSR as
much as we'd like after we've detected that this CPU supports C1E.

But having the value cached is faster and doesn't enlarge checking
code in acpi_processor_cstate_check().

I think the reason for adding the syntetic cpuid flag is only to
communicate to the ACPI processor module that we don't support deeper
C-states on a C1E machine, see a8d6829044901a67732904be5f1eacdf8539604f.
So we don't strictly need it and we can only export c1e_detected to the
rest for simplicity.

No, the difference between using a separate variable and the CPU feature 
bit is that CPU feature bit is ANDed across all CPUs, whereas this 
variable is set if it is set on *any* CPU.

... and that's ok because the MSR bits get set on all cores after BIOS
turns on C1E. Let me verify this though.

I don't see the need for two things denoting C1E for the very simple
reason: when C1E gets enabled on a machine, one of the bits gets set in
the MSR on each core simultaneously. So if one core sees one of the bits
set, all the remaining cores are seeing them too. The first core that
sees one of the bits in the MSR, sets c1e_detected.

So next time any core does cpu_idle() => c1e_idle(), it switches to
timer broadcast on it since it might go into C1E if all the others
follow.

Frankly, I can't think of a case where we'd need to two things - I
could be missing something. But this workaround is a couple of years
old, maybe Thomas might give us more insight into whether there's a
particular reason for the cpuid flag and the c1e_detected variable.

I'm not saying there should be two things (and that's clearly wrong no
matter what), but rather it's not clear to me that the one thing should
be a variable.

Why not? Once one of the MSR bits is turned on, it stays on until next
reboot. The variable caches that value which will not change and saves
us the rdmsr everytime a cpu goes idle. So I don't see the need to have
a function instead which checks the MSR everytime, for example.

Btw, I think we should wait with whatever fix we come up until the
merge window so that we have more time to fix any fallout then (which I
don't expect but who knows) instead of rushing this now. We can always
backport it then too.

Ok, I think we should go ahead and queue this up for .36 for now, let
it see some linux-next time and such. The other issue with the Gigabyte
boards is still ongoing and, as it looks so far, unrelated.

Subject: [PATCH] x86: fix keeping track of AMD C1E

Accomodate the original C1E-aware idle routine to the different points
during boot when the BIOS enables C1E. While at it, remove the synthetic
CPUID flag in favor of a single global setting which denotes C1E status
on the system.

Did apply this patch to stock 2.6.35-rc5, it does _not_ fix my C1E problem.
It takes a lot of key pressing in the boot process to get the system up,
just as it has been before.

(I'll post my dmesg with your debugging patch applied in another mail.)

Well, no wonder it wouldn't work - you seem to have that funny Gigabyte
BIOS which botches lapic and ioapic id enumeration and obviously
enabling C1E in the SMI handler (excerpt from your dmesg):

ACPI: LAPIC (acpi_id[0x00] lapic_id[0x00] enabled)

See how the IOAPIC's and the third LAPIC's ids are the same?
That's wrong. There are couple people with the same problem:
https://bugzilla.kernel.org/show_bug.cgi?id=15289. And as comment #53
says, we're trying to talk to Gigabyte to fix this and the C1E problem.
For now, you can disable C1E in the BIOS, use "idle=mwait" and put
yourself on the CC list of that bug. Sorry, I wish I could give you
better news.

Ok, come to think of it, there are a couple of things you could also test:

First of all, there's this HPET readback on ATI chipsets which wasn't in
your testing kernel and it would be a good thing to test it - I'm little
sceptical but it fixes the same symptoms for another user so it wouldn't
hurt. You'll have to apply the following patches:

1. The latest fix from Michal (adding it here for completeness):

Please boot this on your machine and send me the whole dmesg, as usual.

Now, if it still shows hickups, we'd like to rule out that there's some
funny HPET IRQ routing issue so please rerun the same test with the same
2 patches ontop but also with "nolapic_timer hpet=verbose" on the kernel
command line. As above, catch the whole dmesg and send it to me.

Appying these 2 patches to 2.6.35-rc5 didn't help, the machine is stalling
as usual and several key presses are required to get it to boot.

Did it, and now it boots fine without any delay/stalling.
Did also try stock/vanilla 2.6.35-rc5 with "nolapic_timer hpet=verbose",
and it does boot fine, too.

> As above, catch the whole dmesg and send it to me.

Attached are three files,

dmesg-01 = output of 2.6.35-rc5 + the two patches
dmesg-02 = output of 2.6.35-rc5 + the two patches + "nolapic_timer
 hpet=verbose"
dmesg-03 = vanilla 2.6.35-rc5 + "nolapic_timer hpet=verbose"

Thanks,
Heinz.

Can you please boot using acpi_skip_timer_override kernel parameter?
I recently had a chance to test on another Gigabyte mainbaord which
showed similar symptoms as your system. I did not find suspicious
things in HPET or APIC configuration but this kernel option worked
around the problem.

Yeah!

This works around the problem on my system, too! Now it boots 
quite normally, with C1E enabled.

Heinz.

That's exactly what I see. Unfortunately, this patch doesn't fix it for me
either (applied to 2.6.35-rc5).

[PATCH 2/2] x86: remove c1e_mask

[Michal Schmidt]

c1e_mask is redundant. The information about activated timer broadcast for
AMD C1E is kept in the CPU feature flags.

The chipset is 890FX. Motherboard Asus M4A89TD PRO/USB3.
BIOS is the latest version: 0901 (05/17/2010 according to dmidecode)

I found another person reporting the same symptoms on
