[Asterisk-Users] te110p and interrupts

[Anton Krall]

This system has acpi enabled. This is how the cards looks like:
 
217:   22201132   17764597   IO-APIC-level  wcte11xp
225:   20253291   19707036   IO-APIC-level  wctdm
233:   17510466   22474179   IO-APIC-level  wctdm

 
but if you run lspci .vb to see how the system sees the cards:
 
02:02.0 Network controller: Tiger Jet Network Inc. Tiger3XX Modem/ISDN
interface
        Subsystem: Unknown device 795e:0001
        Flags: bus master, medium devsel, latency 32, IRQ 5
        I/O ports at 2000
        Memory at dd200000 (32-bit, non-prefetchable)
        Capabilities: [40] Power Management version 2

02:08.0 Network controller: Tiger Jet Network Inc. Tiger3XX Modem/ISDN
interface
        Subsystem: Unknown device b119:0001
        Flags: bus master, medium devsel, latency 32, IRQ 5
        I/O ports at 2800
        Memory at dd201000 (32-bit, non-prefetchable)
        Capabilities: [40] Power Management version 2
 
03:02.0 Network controller: Tiger Jet Network Inc. Tiger3XX Modem/ISDN
interface
        Subsystem: Unknown device b119:0001
        Flags: bus master, medium devsel, latency 32, IRQ 5
        I/O ports at 3000
        Memory at dd400000 (32-bit, non-prefetchable)
        Capabilities: [40] Power Management version 2

 
I dont get it, the system sees everything on IRQ5 eventhough the kernel sees
everything in diff. IRQ:
 
02:02.0 Network controller: Tiger Jet Network Inc. Tiger3XX Modem/ISDN
interface
02:08.0 Network controller: Tiger Jet Network Inc. Tiger3XX Modem/ISDN
interface
03:02.0 Network controller: Tiger Jet Network Inc. Tiger3XX Modem/ISDN
interface

Also, latency for the cards is 32... 
 
i enabled the watchdog on zttool and I do see Missed IRQ/interrupts on
zttooll for the te110p card... how can I fix this?
 
Ive read some stuff around but so far.. nothing makes sense to me... :(

use lspci -vb for detecting interrupt conflicts..

Guys. I have an issue with a te110p card and also some tdm04b cards on the 
same system:

Zttest returns this for the tdm04b cards:

Im getting problems receiving faxes which can be caused by this.

As you can see, the cards are not sharing IRQs as far as I cant tell

           CPU0       CPU1
  0:   17697848   17714488    IO-APIC-edge  timer 
  7:          2          2    IO-APIC-edge  parport0
  8:          1          0    IO-APIC-edge  rtc
  9:          0          1   IO-APIC-level  acpi
14:     103455     112606    IO-APIC-edge  ide0
15:          0          0    IO-APIC-edge  libata
169:          0          0   IO-APIC-level  uhci_hcd:usb2
185:    2793868         12   IO-APIC-level  eth0
201:          0          0   IO-APIC-level  ehci_hcd:usb1
209:          0          0   IO-APIC-level  uhci_hcd:usb3
217:   19672684   15531101   IO-APIC-level  wcte11xp
225:   17824822   17371238   IO-APIC-level  wctdm
233:   15323598   19896224   IO-APIC-level  wctdm

So, can anybody point me in the right direction in order to debug the 
problem with zttest and quality of sound?
How can I change prioritiess for the cards or maybe adjust or see if they
get their right number of interrupts, etc?

Thx for the help guys!
