Subject: upstream regression (IO-APIC?)

The current Linus tree as of commit e946217e4fdaa67681bbabfa8e6b18641921f750
is broken for me. I get either the following panic (see log from qemu below)
or lost IRQs on ATA init... Is this a known issue?

PS The tree that I used before and was supposedly good (sorry, I'm too tired
to verify it now) had commit 57f8f7b60db6f1ed2c6918ab9230c4623a9dbe37 at head.

What's the bootup dmesg from a working kernel?

Unfortunately 57f8f7b60db6f1ed2c6918ab9230c4623a9dbe37 (v2.6.28-rc1)
is also bad. Bisecting it further was a real pain (i.e. I hit broken
build with x86 irqbalance changes, broken build with netfilter nat
changes and jbd journal problem). In the end it turned out that 2.6.27
is bad too! However with 2.6.27 the panic occurs only once per several
attempts and if there is no panic kernel boots normally (no lost IRQs).

[...]

I finally managed to narrow it down to change making x86 use tsc_khz
for loops_per_jiffy -- commit 3da757daf86e498872855f0b5e101f763ba79499
("x86: use cpu_khz for loops_per_jiffy calculation"). This approach
seems too simplistic (as I see now Arjan & Pavel expressed concerns
about it back when the patch was posted initially [1][2]). Also it
would probably be preferred to re-use existing preset_lpj variable
(just like KVM does it for similar purpose [3]) instead of adding a
lpj_tsc one and increasing complexity.

Applying following hack to current Linus tree fixes the panic:

It turned out that I can boot a kernel with different config with
HZ == 250 just fine and switching to HZ == 1000 makes it fail.


Looking into it some more:

HZ == 250 kernel (good):

Calibrating delay loop (skipped), value calculated using timer frequency.. 2986.79 BogoMIPS (lpj=5973580)

HZ == 1000 kernel (bad):

Calibrating delay loop (skipped), using tsc calculated value.. 2990.35 BogoMIPS (lpj=1495176)

HZ == 1000 kernel with hackyfix (good):

Calibrating delay using timer specific routine.. 3016.68 BogoMIPS (lpj=6033376)


Argggh... lpj is used for udelay() & friends so this bug is quite
dangerous (since udelay() & friends are used for hardware delays)...

[ The commit works for HZ == 250 because it does tsc_khz * 1000 / HZ,
tsc_khz * 4 => lpj assumption holds true and there is no frequency
scaling at boot. ]

The quick fix would be to replace 1000 / HZ by the magic number "4"
but the major question is whether can we reliably depend on the tsc_khz
for lpj?

Thanks,
Bart

It may be not as severe as I initially thought,
(obviously) the real hardware works fine:

calibrate_delay_direct(): lpj=1495884
Calibrating delay loop (skipped), value calculated using timer frequency.. 2990.36 BogoMIPS (lpj=1495183)

So the issue only affects qemu ATM.

Bart

That's not right, the magic number 4 thing would not be correct.
On one of my systems for eg, i get this in dmesg

Detected 2010.400 MHz processor.
...
Calibrating delay using timer specific routine.. 4022.47 BogoMIPS
(lpj=2011235)

This is with an earlier kernel, the HZ value is 1000. And the lpj value
that we get from the calculation of (tsc_khz * 1000)/HZ is correct in
this case. And on all the systems that i have checked this assumption
holds true.

One of the things that i suspect is that you are not using delay_tsc in
this case, i.e. tsc is not used for delay which is causing that panic

can you please try the patch below on your system ?

If the patch above doesn't help, I think the answer to your question is
- not on some particular hardware, but we would know.
Btw, what h/w are you running this on ?

Oh so its on a emulator, something wrong in the timer emulation logic in
qemu ?

Yes, I realized this once I tried to reproduce issue on the real h/w.

Didn't help but it looks like we should apply it anyway
(so "notsc" continues to work as before).

Probably. I now noticed that the problem happens only with HZ == 250 host
and HZ == 1000 guest. When host and guest are using the same HZ setting
everything works fine.
