[linux-dvb] [PATCH] cx23885 analog TV and audio support for HVR-1500

[linux-dvb] [PATCH] cx23885 analog TV and audio support for HVR-1500

[Mijhail Moreyra]

Hi,

This patch adds analog TV support for the HVR-1500 which has a cx23885 
bridge and a xc3028 tuner but no MPEG encoder. It also adds support for 
ALSA audio capture.

There isn't digital TV in my country so I didn't test if it breaks 
digital mode.

Hope it will be useful for anyone interested.

Regards.
Mijhail Moreyra

Indeed, very nice, thank you!

I'll generate a ~stoth/cx23885-audio tree and encourage a few people to 
test.

That's great but then it would be nice to add the required configuration 
for the cx23887 bridge to cx23887_sram_channels for TV Audio so more 
people can test it.

Mijhail,

Can you give me your sign-off for the patch?

Thanks.

I was waiting some testing and comments first but anyway
the patch I sent before is

Mijhail,

http://linuxtv.org/hg/~stoth/cx23885-audio

This tree contains your patch with some minor whitespace cleanups and 
fixes for HUNK related merge issues due to the patch wrapping at 80 cols.

Please build this tree and retest in your environment to ensure I did 
not break anything. Does this tree still work OK for you?

After this I will apply some other minor cleanups then invite a few 
other HVR1500 owners to begin testing.

Thanks again.

Regards,

Steve

Hi, sorry for the delay.

I've tested the http://linuxtv.org/hg/~stoth/cx23885-audio tree and it 
doesn't work well.

You seem to have removed a piece from my patch that avoids some register
modification in cx25840-core.c:cx23885_initialize()

-       cx25840_write(client, 0x2, 0x76);
+       if (state->rev != 0x0000) /* FIXME: How to detect the bridge 
type ??? */
+               /* This causes image distortion on a true cx23885 board */
+               cx25840_write(client, 0x2, 0x76);

As the patch says that register write causes a horrible image distortion
on my HVR-1500 which has a real cx23885 (not 23887, 23888, etc) board.

I don't know if it's really required for any bridge as everything seems
to be auto-configured by default, maybe it can be simply dropped.

Other than that the cx23885-audio tree works well.

WRT the whitespaces, 80 cols, etc; most are also in the sources I took
as basis, so I didn't think they were a problem.

Regards,

Mijhail Moreyra

That's a mistake, I'll add that later tonight, thanks for finding this. 
I must of missed it when I had to tear apart your email because of HUNK 
issues caused by patch line wrapping.

Apart from this, is everything working as you expect?

Steve

OK.

And sorry about the patch, I didn't know it was going to be broken that
way by being sent by email.

I'll try asking again since my replies in gmail were not including the
correct subject heading.
Can this code for cx23885 analog support be adapted for the DViCO Fusion
HDTV7 Dual Express which also uses the cx23885?  Currently the driver for
that card is digital only and I am stuck with a free antiquated large
satellite system that is analog only in my apartment. I am willing to put in
the work if someone can point me in the right direction.  Thank you,

--Tim

Wait until I get a chance to merge the cx25840 fix late tonight. Watch 
the stoth/cx23885-audio tree for a cx25840 fix appearing, then test the 
driver. Look in the driver, find the correct card=N option for the 
HVR1500 and load the driver on your system with that option .... then 
try analog.

Tim,

The patch currently being tested only enables the analog video path on
the HVR1500, but this does lay down the ground work to bring up analog
on all of the other cards.

If the HVR1500 is working properly, then it will be easy to add analog
support for the HVR1500Q ... Once that is done, the exact same code
(for analog) will be reused for the FusionHDTV7 Dual.

Keep in mind, however, that you will only get ONE analog video device
on the F7 Dual, and that you must not try to use the first DVB adapter
while using the analog on that board.  You can always use the 2nd
adapter , though.

Actually, I think it might be a good idea to reverse the registration
order of the DVB adapters in the cx23885 driver, but I'll have to talk
to Steve about that.

I think it makes more sense to register VIDC first, since VIDC is
always going to be a DTV device, where there *might* be an encoder on
VIDB.

VIDB may or may not share a tuner with VIDA, but VIDC will always be
independant.

What do you think about that, Steve?

Regards,

Mike

The patch should add analog TV and audio support for any cx23885 based
card but currently it assumes a xc3028 tuner so an appropiate tuner
callback must be set up if needed.

The patch should also work with 23887 based cards but needs some
configuration for the SRAM TV audio channel.

Mijhail Moreyra

Yes, this can help us to enable the DMA Audio on the HVR-1800.  Analog
video already works on the HVR1800, both raw video and hardware mpeg
encode, but audio during raw video (ie: tvtime) support was missing.

There are some differences between the cx23885 and the cx23887, but
this all does help a lot.

Give it some time, we'll get all the cx23885 cards tested and check
the '887s also.

There are a lot of big changes happening right now all at once,
especially if you look at today's mailing list traffic.

I can't promise that everything will get completed immediately, but
now everybody can see what's in progress :-)

Regards,

Mike

Thanks, let me know if you need anyone to test. I got an HVR-1800, and i
just got done upgrading to the latest kernel.

I'm willing to work with anyone to iron out the bugs on this card.

I think we should indicate the load order in the cards struct, the 
default should remain as-is, but each specific card could chose to do C, 
then B, or B then C.

I don't think it's safe to assume that VIDC will not share a tuner with 
VID_A.

I'll put some patches together in the cx23885-audio tree when I do some 
testing this weekend, allowing the creation order to be changed.

Tim,

The audio fix has now been applied to 
http://linuxtv.org/hg/~stoth/cx23885-audio.

Try loading the card as the HVR1500 and see what happens.

Mijhail, if you could download and compile the cx23885-audio tree one 
more time I would be grateful.

Regards,

Steve

Hi,

I've tested the corrected cx23885-audio tree and it works well, all the
changes from my patch are included and I can confirm that analog TV and
audio work for my HVR-1500 with that tree.

No, that's loaded fine.

Ignore the digital VIDC attach errors. How is analog TV working?

Please cc the list in all email, which I've done.

Check the /var/log/messages or kern.log files to see what they contain.

Or, if the system isn't booting, remove the module from your 
/lib/modules/`uname -r`/kernel/drivers/media/video/cx23885 dir then boot 
again.

The card won't get initialised by the driver won't exist, then you can 
install the driver with 'make install' which will install it from your 
linux-dvb/v4l test tree, then load it at your own leisure with modprobe 
cx23885 debug=1.

I followed your instructions
modprobe cx23885 debug=1 says operation not permitted
Then I tried sudo modprobe cx23885 debug=1 and it says the process was
killed.  I get the following from dmesg:

I still cannot scan for channels.  The card is listed as v4l audio card in
the mythtv backend setup.  When I try to setup "Input connections", I am
given three choices for inputs, television, S-video and composite.  Choosing
either of the last two makes mythtv crash.  The first one allows me to scan
for channels, but I have no signal.

Thanks for your continual help.

Using your instructions, I figured out that the driver will not load using
modprobe. That is why the computer has trouble booting with that driver and
the HVR-1500 card selected.I also tried copying the relevant code and
putting it into the DViCO FusionHDTV7 Dual Express area to see if that
worked. I had the same results as when I tried loading the card as a
HVR-1500. I cannot get any signal from the card that way.  I know the card
is getting a signal because it shows a signal when loaded as a digital card.
 If you have any suggestions I would appreciate them.  Thank you.

Why doesn't the driver load if you force it with card=X? What does dmesg 
show?

I followed your instructions modprobe cx23885 debug=1 says operation not
permitted
Then I tried sudo modprobe cx23885 debug=1 and it says the process was
killed
This is the output from dmeg.

I am still trying to resolve this issue.  Loading the HVR1500 driver does
not work.  You can check the dmesg above and I think the problems start at
the line

[  589.382427] tveeprom 5-0050: Encountered bad packet header [ff]. Corrupt
or not a Hauppauge eeprom.

I would still like to try to get analog support working for my DViCO
FusionHDTV7 Dual Express.  This seemed like my best prospect.
