I'm looking at this based on Hans initial work and what the *.inf file
for Vista has in it.

Right now, until the cards entry for the MPC718 in cx18-cards.c has a
capability other than "0", the driver will not be usable.

I've started fixing up the cards entry. Here's what I've got so far:

-------------
static const struct cx18_card cx18_card_mpc718 = {
.type = CX18_CARD_YUAN_MPC718,
.name = "Yuan MPC718",
.comment = "Experimental support!\n",
.v4l2_capabilities = CX18_CAP_ENCODER,
.hw_audio_ctrl = CX18_HW_CX23418,
.hw_all = CX18_HW_TUNER,
.video_inputs = {
{ CX18_CARD_INPUT_VID_TUNER, 0, CX23418_COMPOSITE2 },
{ CX18_CARD_INPUT_SVIDEO1, 1,
CX23418_SVIDEO_LUMA3 | CX23418_SVIDEO_CHROMA4},
{ CX18_CARD_INPUT_COMPOSITE1, 1, CX23418_COMPOSITE1 },
#if 0
/* The Windows *.inf file says S-Video 2 uses 7 & 8 */
/* This combination should be illegal, I think */
{ CX18_CARD_INPUT_SVIDEO2, 2,
CX23418_SVIDEO_LUMA7 | CX23418_SVIDEO_CHROMA8},
#endif
{ CX18_CARD_INPUT_COMPOSITE2, 2, CX23418_COMPOSITE6 },
},
.audio_inputs = {
{ CX18_CARD_INPUT_AUD_TUNER, CX23418_AUDIO5, 0 },
{ CX18_CARD_INPUT_LINE_IN1, CX23418_AUDIO_SERIAL, 0 },
/* Guess */
{ CX18_CARD_INPUT_LINE_IN2, CX23418_AUDIO_SERIAL, 0 },
},
.radio_input = { CX18_CARD_INPUT_AUD_TUNER, CX23418_AUDIO_SERIAL, 0 },
.tuners = {
/* XC3028 tuner */
{ .std = V4L2_STD_ALL, .tuner = TUNER_XC2028 },
},
/* tuner reset */
.gpio_init = { .direction = 0x1000, .initial_value = 0x1000 },
/*
* TODO: From the Windows *.inf file it looks like gpio is also used
* for audio routing/control. Need to port GPIO audio from ivtv
*/
.ddr = {
/* Probably Samsung K4D263238G-VC33 memory */
.chip_config = 0x003,
.refresh = 0x30c,
.timing1 = 0x23230b73,
.timing2 = 0x08,
.tune_lane = 0,
.initial_emrs = 2,
},
.pci_list = cx18_pci_mpc718,
.i2c = &cx18_i2c_std,
};

---------

The MPC718's video and audio input look like they're routed to the
cx23418's internal cx25843 core, the same way the MPC622's video and
audio inputs are routed to the external cx25843 by the ivtv driver.

Major tasks to do before the cx18 driver will be useful for the Yuan
MPC718 for analog video::

1. Get the cx18 driver to load xc3028 tuner firmware and setup a xc3028
tuner. (Maybe I can learn from what the cx88 driver does, especially
since the MPC788 may have some things in common with the MPC718.)

2. Figure out/guess/verify the proper GPIO settings for
reseting/controlling the tuner.

3. Figure out/guess the GPIO settings for routing/enabling audio and
port the gpio audio stuff over from ivtv.

4. Other stuff that's bound to pop up.

What you have the best shot of working right now is analog encoding of
Composite 1, Composite 2, or S-Video 1 without sound.

If you feel compelled to test something that you know is not going to be
fully operational, the modified cards entry I gave above, may let you
test Composite 1 or 2 or S-Video 1 without sound.

All of the above looks OK.

The automatic audio standard detection firmware for the cx25843 digitzer
core inside the cx23418 couldn't be loaded. This shouldn't matter for
now to test Composite video and baseband audio.

I not sure why a /sysfs/devices/pci0000:00/0000:03:00.0 dirent existed
already at this point nor why firmware load would try to create one, if
it needed one and one already existed. Possible race condition to hunt
down....

That section of card 0 and card 1 initialization looked OK.

Ack! card 0 tuner firmware load didn't happen, but you wouldn't think it
was card cx18-0 given the "cx18--279773184"!

It looks like cx18_reset_tuner_gpio() is being passed a bad callback
pointer as the code to fetch cx->num from the callback pointer is
correct. In this function, we don't actually have the real data we need
to work with. We won't be able to reset the xc3028 tuner chip until
this is resolved.

That would also imply that the tuner-xc2028 driver has stored away the
wrong data or corrupted the callback data we gave it to store.

We'll probably need to set options for the tuner.ko and tuner-xc2028.ko
modules in /etc/modules.conf for some more verbose debugging. Something
like:

options tuner debug=1
options tuner-xc2028 debug=1

It could be that cx18 is making initialization calls for the tuner
improperly, but from an hour or so look at it, it looks like cx18 is
doing that right as well.

Also, the bad callback data being passed to cx18 may be simply due to
using older (wrong) tuner*.ko modules. Can you do a

$ find /lib/modules -name "tuner*" -print

and see if you have two versions of tuner.ko or tuner-xc2028.ko under
the kernel version you are using? The modules under "common" are the
more recent due to recent changes in the latest v4l-dvb. Any duplicate
modules under "video" are older and can be deleted (or backed-up out of
the way) if there is a corresponding one under "common".

Same problem about bad callback data being passed back to the cx18
driver on a call back from the tuner drivers.

But this time for card "cx18-1" or alternatively card
"cx18--1002536960", however you prefer to refer to the second card in
your machine. ;)

OK. You should be able to test analog Composite video/basedband audio
and Svideo/baseband audio. Especially on card 1 (e.g. /dev/video1) and
probably on card 0 (e.g. /dev/video0), although since the cx25843 audio
firmware messed up on card 0 it may not work so well. Analog RF
reception isn't going to happen until the bad callback data being passed
from the tuner-xc2028.ko module is resolved.

Please see Hans instructive post on getting a new card up and working:

http://ivtvdriver.org/pipermail/ivtv-devel/2008-May/005543.html

and let us know how things go.

Just to pitch in: last Tuesday my cx18 xceive tuner code was merged in
the v4l-dvb tree, so I know that in that tree this tuner works well
(analog only). The xceive_pin field in the card definition of
cx18-cards.c probably needs adjusting for the xceive firmware load to
work, though. The full range is 0-31, but I would test the range 8-15
first. Basically a matter of 'rmmod cx18', edit/make/install
cx18, 'modprobe cx18' and check if the fw is now loaded correctly.

Regards,

Hans

I've copied the devel list, so that google can help those that follow
you. Maybe there's one one the wiki at ivtvdriver.org, I don't know.

v4l2-ctl defaults to /dev/video0 if a device is not specified. See

$ v4l2-ctl --help

Sp you'll want to try:

$ v4l2-ctl -d /dev/video1 -i1 <--- Sets input #1
$ v4l2-ctl -d /dev/video1 -I <--- Reads back current input setting
$ cat /dev/video1 > test.mpg <--- Does a capture

Keep MythTV out of the loop. For testing we generally want to eliminate
variables and unknowns, and only change one parameter at a time. MythTV
often makes that impossible. ;)

Well, then the tuner works? :)

I haven't set up lirc yet for my card, either. No immediate need.

For /dev/video0 by default! :)

No big deal. One can't seek backwards in the input pipe, as the OS
discards the data once mplayer reads from the input pipe. This is
expected behaviour.

I don't use/have Win32 codec's in my installation, but AVI format
doesn't matter as the CX23418 isn't capable of generating that file
format. So no big deal.

Good!

With 25.0000 fps, it looks like you have a PAL source of some sort.
Since it's exactly 25.000 fps, is it a Black and White source?

No big deal.

Your system is probably to slow to not use caching.

Also recall that the current cx18 driver doesn't do the first analog
capture after modprobe properly. So if you have no audio or lots of
missing frames on the first capture don't worry.

So after a modprobe, start mplayer on a cx18 device, stop mplayer, and
start it again.

Here's how I typically invoke mplayer for my HVR-1600:

$ mplayer -cache 8192 /dev/video1

You can use 16384 or some higher number, if your system appears to need
it. The cache parameter appears to be smoothing out the frame delivery
to the software decoder, as, I think, the cx23418 may be sending encoded
frames at not such a steady rate.

Andy
