[PATCH] x86_64: check_timer with io apic setup before try_apic_pin

In the check_timer, it forget to set up the io apic before try_apic_pin for
timer. So add set_try_apic_pin to set up the io apic pin. otherwise the 
try_apic_pin will not work.

also add remove_irq_to_pin to corresponging to add_pin_to_irq to make irq_2_pin
more complete and make the set io apic more convenient.

Also add add_irq_entry in mparese.c to add apic/pin pair to mp_irqs in case 
some nvidia based MB have wrong io apic pin entry for timer. Some ck804 based 
MB, MPTABLE or ACPI assume timer is on ioapic pin2. but HW is set to pin0. or 
reversing case.

the check_timer will try 
1. apic1, pin1 with 8259 IRQ0 disabled
2. apic=0, pin=0 with 8259 IRQ0 disabled
3. apic=0, pin=2 with 8259 IRQ0 disabled
4. apic1, pin1 with 8259 IRQ0 enabled
5. apic2, pin2, pure 8259A routing on the 8259 as reported by BIOS

without the patch:
..TIMER: trying IO-APIC=0 PIN=0 with 8259 IRQ0 disabled<3> .. failed

Yinghai, Eric, can you please send me the latest version with 
 (a) explanations for the changelogs
 (b) sign-off's (and acks for Eric, please) on it..

Let's get this one off the table.

[PATCH 1/4] x86_64 io_apic: Implement remove_pin_to_irq

[Eric W. Biederman]

To try different irq routing combinations so we can make an informed
guess as to how to route irqs when the BIOS gets it wrong we need
the ability to modify our irq routing data structures.

This adds remove_pin_to_irq which removes the mapping from and apic pin
to an irq.

PATCH 2/4] x86_64 io_apic: Implement irq_from_pin

[Eric W. Biederman]

Another helper needed for guessing the routing of the timer
irq.

irq_from_pin looks at the irq_2_pin mapping and figures
out which irq is connected to a given apic and pin combination.

We need to know this to avoid guessing an apic pin that is already
in use by another irq.

Despite the nested loops this is O(N) walk through the irq_2_pin
data structure.

[PATCH 3/4] x86_64 io_apic: Implment update_irq0_entry

[Eric W. Biederman]

To guess different irq routing strategies for irq 0 we
need the ability to update our data structures to reflect
our guess.

update_irq0_entry updates the mp routing table information
to reflect our current guess as to the routing of the timer
irq.

[PATCH 4/4] x86_64 ioapic: Improve the heuristics for when check_timer fails.

[Eric W. Biederman]

To a large extent this reverts b026872601976f666bae77b609dc490d1834bf77
while still keeping to the spirits of it's goal, the ability to
make smart guesses about how the timer irq is routed when the BIOS
gets it wrong.

The code for testing timer routing of a normal apic pin and
and an ExtINT pin has been moved into functions to make the
code easier to read.

I have assumed that we don't want to enable anything with the i8259
unless we are in ExtINT mode.  Reading the patch log indicates
that this seems to be most if not all of the time.

Compared to the pre b026872601976f666bae77b609dc490d1834bf77 state
two heuristic guess have been added:
-  If we cannot make the BIOS supplied timer on an apic pin work we
   guess apic 0 pin 2. As that is the architectural default.
-  When that fails and the BIOS does not provided us with an ExtINT
   mapping we try apic 0 pin 0 as an ExtINT.

Compared to Andi's previous version:
- I do not turn on irq0 in the i8259 and see if the io_apic
  works.  It is not clear that is ever needed.
- I do not guess that irq0 is connected as an ordinary interrupt
  to ioapic 0 pin 0.  I can't see how misprogramming that pin will buy
  us anything especially as it worked as an ExtINT in my testing, on
  one of the Nvidia boards.
- I guess that ExtINT mode and thus irq0 trough the i8259 works
  through apic 0 pin 0.  As this is the architectural default.

By using the architectural defaults our guesses are as
safe as they can be and are likely to work in most of the
cases.  If this still leaves some people out in the cold
we can look at adding some more smart guesses, but my hunch
is that anything more needs to be chipset specific.

Yinghai Lu thanks for your contributions on the infrastructure
support.  While I did not use it directly I did look at your code
when double checking mine to see if looked correct.

Tobias.  I don't have a box with the problem yours does, and this
doesn't quite try any of the cases you have been asked to test
so could you please test this one?

I have tested this on an Nvidia board that reports that apic 0 pin 2
works when it does not and this code successfully programs apic 0 pin 0
into ExtINT mode.

I have not addressed the fact the code for local apic ExtINT guesses 
are a mess and appear to be broken.  That code appears to have been
that way for a long time and no one has seemed to care.

That's code where every changed line has a great potential of causing a

Why does this piece of code give every one the screaming hebie jebies?
I read it I understand it, it is code.

This code is not a terribly sensitive delicate heuristic, and Andi has
already broken it as much as it can possibly be broken.  It's not like
the code is on a SMP fastpath full of carefully orchestrated races
that are safe because within certain limits even stale values are ok.

This is code is straight forward logic, you tell the computer what to
do and it does it.  Of those things we can do only very few of
them are correct, and we are seeking to enhance our ability to find
correct solutions by adding intelligent guesses.  As long as the first
guess is trust the BIOS the rest of this code is largely a don't
care.  As Andi proved by breaking all the rest of this.  Or why
don't I have more testers just crawling out of the wood work,
screaming for this code to be fixed?

Plus this code can only cause one type of breakage.   A failure to
work around a broken BIOS and make the IRQs work.

If that is the practical translation I am fine with it.

Linus said he wanted to try in the 2.6.20 timeframe.  Although things
have probably dragged on much to long.

The heuristics tests in my patch actually do what they try to do. 
Unlike Andi's where only trusting the BIOS supplied default works.
So from where we are it is a clear benefit.  b026872601976f666bae77b609dc490d1834bf77
is broken.  I just found it easier and more evolutionary to starting
with a working code base.  Not that my result is radically different
codewise from what Andi and tried.

Everything that worked in 2.6.19 should also work.  Except for the ATI
case we still have all of the other heurstic work abounds supplied by
quirks instead of supplied manually, and the ATI fix was to not enable
interrupts on the i8259 and then expect the ioapic to work, which we
have sensibly made a global default.

I really don't care how we do it, or in what timeframe.  But what I have
posted is the only way I can see of making it better, than what we had
in 2.6.19.

I would like to see my code take the conversation to talking about
what intelligent guesses we should try when the BIOS get's it wrong
instead of being stuck where we have with Andi's code about how do we
make the heuristic guesses we want to try actually run.

Now if someone wants to see a beautiful history we can revert Andi's commit
Implement the code motion parts of mine into functions.  Implement what it
takes to make those functions safe to call multiple times, and then call
extra times as heuristic guesses to get the hardware correct.  There
might be some sense in that, although it feels like trying to hard to me.

I definitely think in the 2.6.21 timeframe it makes sense to put this code in
on i386 as well.  Otherwise the maintenance will just be crazy.

We just got a completely different bug reported that was confirmed to be

My whole point is that for 2.6.20, we can live with simply reverting 
Andi's commit.

What to do for 2.6.21 is a completely different story.

Yeah. I have to say, that with my main goal for 2.6.20 being a stability 
release, and the APIC setup scaring me too, I'm starting to strongly lean 
towards just reverting the thing, and then having this whole thing 
re-introduced early during the 2.6.21 cycle with the new information we 
have (ie the clues about exactly why the dang thing broke in the first 
place).

After all, the only reason I didn't want to revert the commit initially 
was that it did clean things up, and I wanted to understand why it didn't 
work. I think we understand why it caused problems, and I think we can fix 
them, but on the other hand, we're already deep into -rc4 with this, so 
let's just revert for now and then clean it up correctly after the 2.6.20 
release.

I have such a machine that showed this problem and when I wrote the patch I 
tested it on it (and on a couple of others of course). No twice as fast on 
my testing.

In fact there are two types of ATI machines: ones that have a BIOS workaround
for the original Linux issue and ones that don't. Keeping both
happy is not easy.

So I'm somewhat dubious on that. Where is that report?

I agree. It's more problematical than I expected. Reverting is 
the best option right now.

Follow the link [1] in my email (and the bug is already assigned to 
you).

Odd. I didn't think Andi's code worked well enough that we could hit
anything but the default trust the BIOS case.  I guess someone had
the right hardware to perform that miracle.

That is where I figured we were when we first hit this bug.

I have always found the ways of stable tree maintainers to be
mysterious.  Sometimes holding back code with minimal risk sometimes
insisting we cleanup things instead of reverting things.

So I have just decided to write the code and let other people figure
out when it should be merged :)  And of course when my code has
problems to address them.

For some CK804 boards, BIOS forget set to 8254 timer to apic0/pin2, and
still leave it at apic0/pin0. but mptable and acpi said 8254 timer is to
apic0/pin2. At such case we should try apic0/pin0 with INT mode instead
of ExtINT mode.

Duh.  I forgot Nvidia provided a register like that, now I am
beginning to understand what is wrong.  Anyway we do try apic0 pin0 by
default on the Nvidia's because of a Nvidia specific work around.

So that doesn't invalidate the generic test.  I'm going to go dig
out what little information I have and see if I can stair at the
register definition.

Anyway that doesn't invalidate anything in this patch.

Did you miss to call irq_from_pin before add_pin_to_irq? You defined
irq_from_pin in PATCH 2/4.

Someone said we can that info about that reg in Kernel. And only
firmware can use that.

We can do all kinds of things when firmware gets it wrong, and in this
case I just want a deeper understanding.  Once I understand that mess
I will decide what to do about it.

Tobias,

Can you post whole log for my patch?

I assume 8254 on apic0/pin2 with INT should work.
