b44: high ping times with wireless-dev

b44: high ping times with wireless-dev

Hello,

I recently did some test and found out something interesting about the b44 
problem I wrote earlier. 

The problem is the following:
When I use my BCM4401 with the b44 driver in wireless-dev I get very high ping 
times looking like this:

64 bytes from 172.30.10.1: icmp_seq=1 ttl=64 time=1863 ms
64 bytes from 172.30.10.1: icmp_seq=2 ttl=64 time=855 ms
64 bytes from 172.30.10.1: icmp_seq=3 ttl=64 time=1855 ms
64 bytes from 172.30.10.1: icmp_seq=4 ttl=64 time=855 ms
64 bytes from 172.30.10.1: icmp_seq=5 ttl=64 time=1854 ms
64 bytes from 172.30.10.1: icmp_seq=6 ttl=64 time=854 ms
64 bytes from 172.30.10.1: icmp_seq=7 ttl=64 time=1851 ms
64 bytes from 172.30.10.1: icmp_seq=8 ttl=64 time=851 ms
64 bytes from 172.30.10.1: icmp_seq=9 ttl=64 time=1851 ms
64 bytes from 172.30.10.1: icmp_seq=10 ttl=64 time=851 ms

I also found out that shortly after I boot my laptop and log into kde ping 
times are not that high but start to increase very quickly:

64 bytes from 172.30.10.1: icmp_seq=53 ttl=64 time=2.19 ms
64 bytes from 172.30.10.1: icmp_seq=54 ttl=64 time=2.22 ms
64 bytes from 172.30.10.1: icmp_seq=55 ttl=64 time=2.20 ms
64 bytes from 172.30.10.1: icmp_seq=56 ttl=64 time=2.20 ms
64 bytes from 172.30.10.1: icmp_seq=57 ttl=64 time=18.6 ms
64 bytes from 172.30.10.1: icmp_seq=58 ttl=64 time=1268 ms
64 bytes from 172.30.10.1: icmp_seq=59 ttl=64 time=268 ms
64 bytes from 172.30.10.1: icmp_seq=60 ttl=64 time=1268 ms
64 bytes from 172.30.10.1: icmp_seq=61 ttl=64 time=268 ms
64 bytes from 172.30.10.1: icmp_seq=62 ttl=64 time=6.08 ms
64 bytes from 172.30.10.1: icmp_seq=63 ttl=64 time=268 ms
64 bytes from 172.30.10.1: icmp_seq=64 ttl=64 time=1264 ms
64 bytes from 172.30.10.1: icmp_seq=65 ttl=64 time=264 ms

After some time digging around I found out something really interesting. When 
I play some music ping times are immediately lower. If I stop playing music 
they are back to the same times as they were before.

I guess that there is a problem with interrupts so I post some information of 
my system in hope it will be usefull.

This problem did only happen with wireless-dev (checkout this evening) and 
with -mm kernels I used some time ago for testing. Currently I'm running 
2.6.22-rc4 that works perfectly fine and doesn't show that problem.

Can you build with APIC for uniprocessor.

There is lots of IRQ sharing, so
 - one of the other device's may be not handling shared IRQ properly.
   Try unloading firewhire modem and yenta devices.

 - IRQ might be set edge triggered which doesn't work with NAPI
	or shared IRQ.

I did enable CONFIG_X86_UP_APIC and CONFIG_X86_UP_IOAPIC and tried with lapic 
and apic=force but couldn't get APIC working.

I did build a kernel without the three mentioned above but the problem is 
still the same. I also did remove everything but eth0 on interrupt 10 so the 
only device using that interrupt is eth0 and then the card completely stopped 
working.

_That_ is interesting...
Maybe the IRQ isn't correctly wired up on the backplane and
it doesn't generate IRQs at all (so it only worked, because other devices
on the same IRQ line triggered the line).
I'll take a look at that code.

Ok, I prepared two debugging patches.

Please enable SonicsSiliconBackplane Debugging in the kernel kconfig,
so I can get more detail information about your card.
Device Drivers/Sonics Silicon Backplane/SSB debugging
(Must disable "No SSB kernel messages")

Please apply and test the attached debugging patches in a row.
So apply patch 1 and test if it works again. If not, apply
patch 2 and test if it works.
Always save complete dmesg log on each test run and send it to me.

Thanks for testing.
(This time it seems we are actually getting somewhere, when
dealing with sane people. :D )

Ah, forgot to say. Apply patch 2 on top of patch 1.

I did the tests with my kernel where only the card is on interrupt 10. dmesg 
is attached.
With the first patch applied networking does work again. I also additionally 
tried patch2 and it also does work.
