[bttv] Auto detection for Provideo PV- series capture cards

[bttv] Auto detection for Provideo PV- series capture cards

[Curtis Hall]

[-- Attachment #1: Type: text/plain, Size: 1523 bytes --]

I'm writing concerning the Provideo PV-149, PV-155, PV-981-* and 
PV-183-*.   These cards, for the most part, are drop in and 'just work' 
with the bttv driver.

However the PV-149 / PV-981 / PV-155 is auto detected as the Provideo 
PV-150, which is not a valid Provideo part number.  The PV-183-* is 
detected as 'Unknown / Generic' and requires setting 
card=98,98,98,98,98,98,98,98.

I believe the text concerning 'detected: Provideo PV150A-1' should be 
changed to 'detected: Provideo PV149 / PV981 / PV155'

I've attached outputs from the bttv kernel logs for the PV-149 / PV-981 
/ PV-183.  If there's something I'm missing please let me know and I'll 
get it for you.

Just for reference the PV-149 / PV-981 / PV-183 series cards are:

PV-149 - 4 port, 4 BT878a chips - no forced card setting required
PV-155 - 16 port, 4 BT878a chips - card=77,77,77,77  (Shares the same 
board and PCI ID / subsystem as the PV-149)

PV-183-8: 8 port, 8 BT878a chips - card=98,98,98,98,98,98,98,98
PV-183-16: 16 port, 8 BT878a chips - card=98,98,98,98,98,98,98,98 
(Shares the same board and PCI ID / subsystem as the PV-183-8)

PV-981-4: 4 port, 4 BT878a chips - no modprobe setting required
PV-981-8: 8 port, 4 BT878a chips  - no modprobe setting required (Shares 
the same board as the PV-981-4)
PV-981-16: 16 port, 4 BT878a chips - card=98,98,98,98,98,98,98,98 
(Shares the same board and PCI ID / subsystem as the PV-981-4)


Thanks!

Did you see the reply from Andy Walls over in video4linux?  He
provided a patch, and asked for a bunch of additional information he
needs in order to get the boards working properly.

Devin,

I saw his email and I've been in private communication between him and 
Provideo trying to get the information he needs.  However his request 
was for the PV-947D against the IVTV driver.  These cards are using the 
bttv driver.  I was hoping a bttv maintainer could look at the 
information I posted first to make sure this information wasn't duplicated.

Thanks!

Ah, my mistake.  I didn't notice that Andy only replied regarding a
board unrelated to your original post.

which is the same ID for PV-150.

The entry for PV-150 were added at -hg tree by this changeset:

Probably, this is a discontinued model, but I don't know for sure.

This one is easy:
[   13.438412] bttv0: subsystem: 1830:1540 (UNKNOWN)

As this PCI ID is not known, it is just a matter of associating the PV-183
ID's with card 98.

Seems ok to me for PV-981.

Hmm... PV-155 shares the same PCI ID as PV-149, but require a different
entry, then we shouldn't add it to the PV-150 autodetection code.

The better would be to check with the manufacturer if is there a
way to detect between those two boards (maybe reading eeprom?).

Why do you need the card=  parameter, if it shares the same subsystem ID
as the other PV-981 models?

We have been Provideo's US distributor since late 2004 and I've not 
heard of a PV-150 part number, and isn't not a current part number.

Okay.  You can easily access four ports on the PV-155 / PV-981, but to 
access the sub (/dev/videoX,1-3) channels you need to add the modprobe line.

I can find out, but getting technical data from Provideo can be more

I think I explained that about with the sub channels, if I'm missing 
something let me know.

Thanks!

This is the original commit when the old maintainer created his tree. It
has all drivers there. The kernel addition is for sure older than 2004.
It is hard to dig into changes that happened before 2004/2005, since in
the past, both V4L and Kernel used different ways to manage patches.

Also, a quick research at the internet showed this site in Australia:

http://www.allthings.com.au/Digital%20Video%20Recording%20Remote%20Viewing%20Web%20Cams/Video%20Capture%20Card%20SDK%208%20Ch%204%20IC.htm

At BTTV gallery (http://www.bttv-gallery.de/), it describes PV150 as:

#  PV150
Pci card with 4 bt878's on board and a HINT PCI-PCI bridge for each
bt878 there is a i2c eeprom (CSI 24WC02P)
and a microprocessor (PIC ?) EM78P156ELP 

Maybe this model were for non-US market.

Could you please send a patch for me to apply upstream?

Then, maybe there are some missing subsystem ID's. In the case of PV-150
entry, it has 4 subsystem ID's. It PV-155/PV-981 are equivalent, then it
will likely have different PCI ID's for each /dev/video[0-3]. Could you
please check it with lspci?

I understand, but, without this data, we cannot add auto-detection.
