[linux-dvb] Very quiet around Nova-T 500

[linux-dvb] Very quiet around Nova-T 500

[Patrik Hansson]

Hello
There is not a lot being said about the Nova-T 500 the last week.
Don´t know if that is a good (coders coding) or a bad (nothin
happening) but i would like to know if there is anything we could do ?

I can´t write code but maybe i can help in some other way ? Testing
builds or whatever.

"Just my 5 cents"

Or coders busy on other code, or coders who ran out of ideas, or coders
enjoying life, etc.

Frustrating, heh?

I took up documenting in the wiki as a way of contributing back,
somehow...

..or just waiting for the problem to reappear ;( The trouble with the
second tuner dying is tricky (for me) to isolate.

As a workaround, enabling full debug (debug=15) on the dvb_usb_dib0700
module has made my system rock solid. I turned on debugging to try to
isolate the issue, but with debugging enabled the problem does not
appear (at least not on my system).

I haven't really figured out *what* in the debug code is helping yet,
but I still suspect that this is timing-related and the debug code
simply slows things down a bit. Enabling debugging will put a whole lot
of "junk" in your system log files, but at least the second tuner wont
die on you. If you go this path, make sure your log rotation works as it
should -- my weekly rotated logs are up to 130 MB in size ;)

Now stop that logging madness and get back to work!

...

;o)


This is a rather comical situation, though... The debugging tool is
providing a rather unexpected and unwelcomed fix.

Hi,

no, it is not. It is well known!

Timings are very critical on almost all drivers.

We hold breath on almost everything coming down from above, nobody has
the ability, or whom should ever want it, to test all possible side
effects on all supported devices ...

That something breaks is very common, and that others have to give the
plumbers, is nothing new.

To stay fair, it mostly has a good reason, and if there are some
remaining ticks left, you might get it adjusted, but ...

On the other side it is the same ...

Cheers,
Hermann

May post may have sounded offensive, apparently.

Sorry about that, my intentions were on the lighter sides of life.

Could someone that knows what they are doing document that option on the wiki ?

Corrected.

The strange thing is that modinfo does not say anything about a level 15
debug for the dvb_usb_dib0700 module.

The debug value is a bit field, with each bit representing a different
category. With all bits on (ie full debugging) the decimal value becomes
15.

I should have guessed.

Documented for poor souls with slow brains like me.

I have now set the debug to 15 and will test this tonight.

nothing offending at all, did enjoy your above comment :)
and like your active support for others.

It is just not totally unexpected that high debug levels can have some
spin-off and I'm curious about it.
