Problem Description:

After upgrading from 2.4.30 to 2.6.13.1 I have noticed very high interrupt rate
for IRQ8 - about 119758 irqs/sec and reduced system performance (probably related).

>  8: 2061632970          0          0          0   IO-APIC-level  rtc

This should be IO-APIC-edge

If you boot with "acpi=off" does it work better?
Comment 2 Shaohua 2005-09-13 22:06:05 UTC
Also it's worthy tring 'pnpacpi=off'. Please provide the acpidmp output too. 
Might the BIOS provide wrong interrupt info for RTC in ACPI tables.
Comment 3 Krzysztof Oledzki 2005-09-15 02:47:04 UTC
Attached acpidump output. Will test pnpacpi=off and acpi=off tomorrow, in 
service window. Thanks!

Comment 5 Shaohua 2005-09-15 18:23:57 UTC
It's a BIOS bug to me.
It claims RTC's interrupt is level/active low. This is wrong. pnpacpi=off can 
workaround your issue.

                Device (RTC)
                {
                    Name (_HID, EisaId ("PNP0B00"))

                        \ASLT (0x77)
                        SLTL (0x10)
                        Name (CRSP, ResourceTemplate ()
                        {
                            IO (Decode16, 0x0070, 0x0070, 0x01, 0x04)
                            IRQ (Level, ActiveLow, Exclusive) {8}
                        })
                        Return (CRSP)
                    }

                    Method (_STA, 0, Serialized)
                    {
                        \ASLT (0x78)
                        SLTL (0x10)
                        If (And (ACTV, 0x01))
                        {
                            Return (0x0F)
                        }
                        Else
                        {

Comment 6 Krzysztof Oledzki 2005-09-20 12:23:09 UTC
(Resending - it seems that latest bugzilla crash droped my comment)


True, pnpacpi=off indeed solved this problem:

   8:          1          0          0          0    IO-APIC-edge  rtc

Thank you.

Is there any other way to force IO-APIC-edge for IRQ8 than completely 
disabling pnpacpi? Or maybe some check for buggy bioses is possible and 
automatically change IO-APIC-level to IO-APIC-edge for IRQ8?

Comment 7 Shaohua 2005-09-20 18:28:13 UTC
PNP device interrupt typically is edge. We could make pnpacpi ignores the BIOS 
setting and always use edge interrupt. But I'm not sure if the assumption is 
always true. I'll ping Bjorn if PNP device interrupt could be level in IA64.

workaround for the issue

The BIOS has bug. It makes rtc interrupt level trigerred. This patch
workarounds it.
I wonder if this can be tested in -mm.
Comment 9 Krzysztof Oledzki 2005-12-07 04:34:51 UTC
It seems that this workaround solved this problem only partially. CPUs are no
longer flooded by interrupts (Thanks, thanks!) but hwclock no longer works. IRQ
count for CPU is increase by one but hwclock fails. Strange.

# cat /proc/interrupts |grep rtc;hwclock; cat /proc/interrupts|grep rtc
  8:          4          0          0          0    IO-APIC-edge  rtc
select() to /dev/rtc to wait for clock tick timed out
  8:          5          0          0          0    IO-APIC-edge  rtc

# cat /proc/irq/8/smp_affinity

Comment 10 Len Brown 2007-08-18 22:58:18 UTC
A related issue has been sighted at novell 214809
where the HPET appears in the DSDT at edge/high,
but it is used in RTC compatibility mode and IOAPIC mode
and there is an INT_SRC_OVR that requests level/low on IRQ8.
It works with pnpacpi=off because it is left at level/low
instead of believing the DSDT and setting edge/high.
The IBM BIOS team asserts it is a Linux bug.

But here we don't have an INT_SRC_OVR on IRQ8...

In any case, the workaround in comment #8 appears to
be incomplete, because it sets the trigger, but not the polarity.

OK, I'll try to extend this patch to also force the polarity.
It should be ACPI_ACTIVE_HIGH, right?

Attached patch fixed my problem, but I would like to check it on three 
other problematic systems to be 100% sure. So far I have tested only one.

BTW: Is it possible to test it for a while in a next -mm?

Thanks for the patch.
Comment 15 Shaohua 2007-10-14 23:21:29 UTC
Krzysztof,
can you try the patch I attached in bug 9153? There is a similar issue  in the bug, but it's about BIOS override. That patch can unified handle the override issue and BIOS bug, so I consider to merge that patch if it works.

Yes, but I will be able to test it at the end of the next week, as I 
currently do not have a direct access to this host and I do not want to do 
it remotely.

Comment 19 Krzysztof Oledzki 2007-10-25 05:27:32 UTC
Patch from bug 9153 works for me:

pnp: IRQ 8 is overrided to edge, high

It only requires a small fix to prevent inserting empty newline:
-			pnp_warn("IRQ %d is overrided to %s, %s\n",
+			pnp_warn("IRQ %d is overrided to %s, %s",

Best regards,
