[Asterisk-Users] te110p and interrupts

I have an issue with a te110p card and also some tdm04b cards on the same system: Zttest returns this for the tdm04b cards: [EMAIL PROTECTED] ~]# /usr/src/zaptel-1.2.4/zttest 38 -v Opened pseudo zap interface, measuring accuracy... 8192 samples in 8191 sample intervals 99.987793% 8192 samples in 8192 sample intervals 100.00% 8192 samples in 8192 sample intervals 100.00% 8192 samples in 8223 sample intervals 99.621582% 8192 samples in 8192 sample intervals 100.00% 8192 samples in 8191 sample intervals 99.987793% 8192 samples in 8192 sample intervals 100.00% 8192 samples in 8192 sample intervals 100.00% 8192 samples in 8191 sample intervals 99.987793% 8192 samples in 8400 sample intervals 97.460938% 8192 samples in 8191 sample intervals 99.987793% 8192 samples in 8192 sample intervals 100.00% 8192 samples in 8192 sample intervals 100.00% 8192 samples in 8191 sample intervals 99.987793% 8192 samples in 8438 sample intervals 96.997070% --- Results after 15 passes --- Best: 100.00 -- Worst: 96.997070 -- Average: 99.601237 And for the te110p: [EMAIL PROTECTED] ~]# /usr/src/zaptel-1.2.4/zttest 1 -v Opened pseudo zap interface, measuring accuracy... 8192 samples in 8239 sample intervals 99.426270% 8192 samples in 8200 sample intervals 99.902344% 8192 samples in 8191 sample intervals 99.987793% 8192 samples in 8191 sample intervals 99.987793% 8192 samples in 8192 sample intervals 100.00% 8192 samples in 8191 sample intervals 99.987793% 8192 samples in 8384 sample intervals 97.656250% 8192 samples in 8191 sample intervals 99.987793% 8192 samples in 8191 sample intervals 99.987793% 8192 samples in 8191 sample intervals 99.987793% 8192 samples in 8191 sample intervals 99.987793% 8192 samples in 8192 sample intervals 100.00% 8192 samples in 8191 sample intervals 99.987793% 8192 samples in 8192 sample intervals 100.00% 8192 samples in 8192 sample intervals 100.00% 8192 samples in 8192 sample intervals 100.00% 8192 samples in 8192 sample intervals 100.00% 8192 samples in 8191 sample intervals 99.987793% 8192 samples in 8192 sample intervals 100.00% 8192 samples in 8193 sample intervals 99.987793% --- Results after 20 passes --- Best: 100.00 -- Worst: 97.656250 -- Average: 99.843140 Im getting problems receiving faxes which can be caused by this.

Re: [Asterisk-Users] te110p and interrupts
Try booting with apic off, I think it's noapic kernel option. Notice
this is "APIC" and not "ACPI", which you referred to. Then get your
boards on different REAL irqs.

RE: [Asterisk-Users] te110p and interrupts
Is this dual CPU/Core or just P4 with HT enabled? If it is P4, I would recommend to disable HT. Try changing PCI slots for one of the cards (if you have spare PCI slots). > CPU0 CPU1 > 0: 17697848 17714488IO-APIC-edge timer ___ --Bandwidth and Colocation provided by Easynews.com -- Asterisk-Users mailing list To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users
RE: [Asterisk-Users] te110p and interrupts
I will try that and see what happens... This server is a supermicro one.. Anybody else had issues like this on supermicro? Any hints on how to resolv them? If I remember correctly, supermicro bios does let you assign irq to certain pci ports right? Will that help? Also, is there a way/is it recommended to increase the latency for these devices? |-Original Message- |From: [EMAIL PROTECTED] |[mailto:[EMAIL PROTECTED] On Behalf Of |Mojo with Horan & Company, LLC |Sent: Monday, April 10, 2006 6:20 PM |To: Asterisk Users Mailing List - Non-Commercial Discussion |Subject: Re: [Asterisk-Users] te110p and interrupts | |Try booting with apic off, I think it's noapic kernel option. |Notice this is "APIC" and not "ACPI", which you referred to. |Then get your boards on different REAL irqs. | |Moj | |Anton Krall wrote: |> This system has acpi enabled.

APIC interrupts are far more "real" than emulated XT-PIC interrupts. If the IO-APIC can put each device on its own "high" interrupt it means that that INT# signal on the PCI slot *is* on a totally separate, physical IRQ line which is routed into that APIC.

Anton, your problem is very likely simple interrupt load. You have three Digium cards in there, and they're all generating their own 1000Hz interrupt. If you did the newbie thing and compiled your kernel with a HZ value of '1000' because you felt it would be better, you have that overhead as well. Your system is very likely just having trouble coping with so many interrupts. My personal opinion is that you should sell the three Digium cards and buy a single dualspan card and a cheap channel bank. Your interrupt load will drop by 2/3 and your system will be FAR happier. So check the kernel HZ value first; I set *all* my Asterisk systems to the old style HZ of 100; there is simply no need for anything more on a server, *especially* if you've already got hardware providing a real 1000Hz interrupt instead of ztdummy trying to emulate such a thing. -A. ___ --Bandwidth and Colocation provided by Easynews.com -- Asterisk-Users mailing list To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users

RE: [Asterisk-Users] te110p and interrupts
Hi Andrew... Thank you very much for the info. I didn't recompile the kernel, Im using a generic 2.6 kernel but its worth taking a look at what you said.. Where can I find (which file) the Hz the kernel was precompiled to? Also, Im running 1 te110p and 2 tdm cards, probably I'll disable 1 card later but I will need at least 1 tdm and the te110p for my E1. So you suggest not disabling any apic/acpi stuff then.. How about HT? should I disable that on the bios? Im using supermicro servers and eventhough I get voice calls without problems, Im getting a few IRQ Misses from time to time which makes faxing on the E1 very difficult (the original problem).

R: [Asterisk-Users] te110p and interrupts
Hi Anton, I'm using a supermicro P4 3GHz P8SCT (Intel E7221 chipset) with TE205P and a TDM04 and I've similar problem. I was using linux 2.6.9smp that seams to have problem with APCI so Hyperthreading, even if enabled, was not working (I sow 1 cpu). Today I've disable hypertrading and start using mono processor kernel, disabled both serial and parallel interfaces (via bios setup), prevent loading of kernel module for second gigabit interface card and zaptel tdm module (I not using tdm04 interface at the moment). These bios changes also seams to have disabled APIC (is it related to hyperthreading ?). However, after all this I've a 4 busy hours of no "chan_zap.c: PRI got event: HDLC Bad FCS (8) on Primary D-channel of span 2" error. I'll make you know for news. Take also a look at http://www.voip-info.org/wiki/view/Asterisk+hardware , chrisre seams to had our same problem with TE110 and supermicro.

Re: [Asterisk-Users] te110p and interrupts
Hi,
I've been battling with a similar issue:
a) I wrote a script to periodically run the command "cat
/proc/interrupts" and figure out the interrupts per second. I run this
script for over 24 hours and never once did the difference between the
preceeding and succeeding interrupt counts go below 1005 (wierd result
because of (b) below);
b) zttest was reporting very bad results;
c) lspci -vb was reporting that the TE110P shared an IRQ with the Gigabit
Ethernet Card (IRQ 11)
d) lspci -vv was reporting that the TE110P was on an IRQ of its own ("IRQ
24") probably because of APIC (wierd because of (c) above);
e) Users reported intermittent bad audio;
Below are the [experimental] steps I took:
a) I'm running a Dual 3.2 GHz machine - the network card is services by
CPU0 - I set the smp_affinity value for the Digium card to be CPU1
b) I disabled the userland 'irqbalance' process which keeps switching the
Digium card between the CPUs
c) I increased the PCI "LATENCY_TIMER" value for the TE110P to a value
higher than the Gigabit Card.
So far, things are looking quite good - zttest is reporting very
encouraging worst-case figures when run over a period of over an hour (it
reports 99.98% worst case at off peak time and 99.77% when run during the
busy hour). Ultimately when I have physical access to the machine, I will
change the PCI slots to see if getting "lspci -vb" to report that the card
is on its own IRQ will improve performance further.
Cheers,
Gerald.

I am curious..
Have you tried disabling CPU1 by setting isolcpus=1 on the kernel command
line ?
This will make the kernel ignore the second CPU - you can then run asterisk
on it by using the taskset command (from schedutils)
taskset 0x0001 asterisk -p
and asterisk wlll run on a CPU all on its own. I was about to try this and
wondered if you might give it a try and report back.

There is a lot of rubbish said about interrupts - if possible use the APIC -
it is the new beast that solves interrupt starvation problems. Seeing if the
card has an IRQ 5 as reported by lspci is misleading - this is the IRQ that
would be used if operating in old mode and in old mode you will have to
disable all kinds of things to make it work. In APIC mode, new hardware comes
into play and each device can have its own interrupt - it is the way to go.
The only problem is that uniprocessor APIC implementations are known to be
badly done - recent motherboards should be OK.

Interesting. Now 'why' do they suggest it, is it because older IO-APIC are 'broken' on some boards?

Additionally I think that HT should not be used if asterisk is doing a lot of transcoding - whilst HT gives u 2 'pipes' there is still only one FPU and heavy transcoding will simply bottleneck at the FPU(NB SSE/MMX count as FP since they use the FP registers.). If u turn HT on, a 1% penalty is incurred fir the mutexes required so heavy use of the FPU will actually show a decrease in speed compared to no HT. In theory at least. :-) Paul Hewlett > > |-Original Message- > |From: [EMAIL PROTECTED] > |[mailto:[EMAIL PROTECTED] On Behalf Of > |Begumisa Gerald M > |Sent: Monday, April 17, 2006 5:13 AM > |To: Asterisk Users Mailing List - Non-Commercial Discussion > |Subject: Re: [Asterisk-Users] te110p and interrupts > | > |Hi Paul, > | > |Thanks for the message! > | > | On Sun, 16 Apr 2006, Paul Hewlett wrote: > | [...] > | > |> I am curious.. > |> > |> Have you tried disabling CPU1 by setting isolcpus=1 on > | > |the kernel > | > |> command line ? > |> > |> This will make the kernel ignore the second CPU - you > | > |can then run > | > |> asterisk on it by using the taskset command (from schedutils) > |> > |> taskset 0x0001 asterisk -p > |> > |> and asterisk wlll run on a CPU all on its own.

RE: [Asterisk-Users] te110p and interrupts
What you say makes a lot of sense... Well.. I disabled HT and Im still having irqmisses :( I stil have to try the latency idea.. Hope that helps.. |-Original Message- |From: [EMAIL PROTECTED] |[mailto:[EMAIL PROTECTED] On Behalf Of |Paul Hewlett |Sent: Monday, April 17, 2006 12:19 PM |To: asterisk-users@lists.digium.com |Subject: Re: [Asterisk-Users] te110p and interrupts | |On Monday 17 April 2006 12:39, Anton Krall wrote: |> I don't know if this only works with multiple cpus but I have HT |> enabled and it shows cpu0 and cpu1 ..
