cx18: Question for users...

Hi all,

I have a question.

For users of HVR-1600 and other CX23418 based cards that basically work:
is your card behind a PCI-PCI bridge chip that is set for "subtractive
decode"?

For users of HVR-1600 and other CX23418 based cards that basically don't
work: Is your card behind a not behind a PCI-PCI bridge chip that is set
for "subtractive decode" (i.e. directly behind a host bridge, or behind
a PCI-PCI bridge set for positive decode)?

Here's an example, run as root, showing how to see if you have the
CX23418 behind a PCI-PCI bridge set for subtractive decode:

# lspci -tvv
-[0000:00]-+-00.0 ATI Technologies Inc Unknown device 7911
+-01.0-[0000:01]----05.0 ATI Technologies Inc Radeon 2100
[...]
+-14.4-[0000:03]--+-02.0 Internext Compression Inc iTVC16 (CX23416) MPEG-2 Encoder
| \-03.0 Conexant CX23418 Single-Chip MPEG-2 Encoder with Integrated Analog Video/Broadcast Audio Decoder
[...]

>From the tree view above, we see the CX23418 is behind the bridge at
00:14.4.

# lspci -s 0:14.4 -vv -x
00:14.4 PCI bridge: ATI Technologies Inc SBx00 PCI to PCI Bridge (prog-if 01 [Subtractive decode])
^^^^^^^^^^^^^^^^^^^^^^^
[...]
00: 02 10 84 43 07 01 a0 02 00 01 04 06 00 40 81 00
^^^^^^^^
||
Subtractive Decode PCI-PCI ----++
[...]

Here we see in the first text line for the bridge, lspci has shown us
its a PCI-PCI bridge in subtractive decode. This could also be read off
of bytes 09x-0xb of the configuration space. The byte at 0x9 being 1
indicate subtractive decode vs positive decode.

Thanks in advance for your responses.

Regards,
Andy

Wow, I need to learn how to type. Let me try that second one again:

For users of the HVR-1600 and other CX23418 based cards that basically
don't work: Is your card not behind a PCI-PCI bridge chip that is set

I'm on an older version of the driver, however. I'll update and see if
there is any difference.

Yes, almost.

Does your card work for you in this configuration behind a bridge in
Normal decode?

OK. Your card appears to be right on the main segment behind the host
CPU bridge.

Does the card and cx18 driver work for you in this configuration?

Yes. This card works. I use it with mythtv.

Yeah, aside from not having a decent antenna, the channels I can pick up
usually come in well. Currently the analog is connected to the RF out of
our satellite unit, and I use MythTV to watch. When I updated my kernel
and the drivers from the repo, I also got an invalid firmware error. So
I untarred them again and replaced the existing ones, and then did a
modprobe cx18. I'm not sure if replacing the firmware or reloading the
module did the trick.

I'm still seeing those i2c errors, but I'm not sure if they are causing
any harm. I haven't actually sat and watched a stream for some time, the
FTA satellite has been down for a couple of weeks now.

Looking at your logs and given my knowledge of the problem, the module
reload when the PC bus wasn't very busy is what fixed things.

At first I was a bit dismayed to see your card not behind a subtractive
decode PCI-PCI bridge and still working - it went counter to my current
hypothesis on the underlying problem many users are experiencing. :(

Now that I see you do have problems (but to a lesser extent), that still
fits with my hypothesis and I can continue on my current
troubleshooting/solution path. :)

Thanks for your response.

Andy
