Hello,
the radio-maestro driver is badly broken. It's intended to drive the radio on
MediaForte ESS Maestro-based sound cards with integrated radio (like
SF64-PCE2-04). But it conflicts with snd_es1968, ALSA driver for the sound
chip itself.
If one driver is loaded, the other one does not work - because a driver is
already registered for the PCI device (there is only one). This was probably
broken by conversion of PCI probing in 2006:
ttp://lkml.org/lkml/2005/12/31/93
How to fix it properly? Include radio functionality in snd-es1968 and delete
radio-maestro?

Interesting. I don't know anyone among the video4linux developers who has
this hardware, so the radio-maestro driver hasn't been tested in at least
6 or 7 years.
The proper fix would be to do it like the fm801.c alsa driver does: have
the radio functionality as an i2c driver. In fact, it would not surprise
me at all if you could use the tea575x-tuner.c driver (in sound/i2c/other)
for the es1968 and delete the radio-maestro altogether.
Both are for the tea575x tuner, although radio-maestro seems to have better
support for the g_tuner operation. It doesn't seem difficult to add that to
tea575x-tuner.c.
The fm801 code for driving the tea575x is pretty horrible and it should be
possible to improve that. I suspect that those read/write/mute functions
really belong in tea575x-tuner.c and that only the low-level gpio actions
need to be in the fm801/es1968 drivers.
Hope this helps.
Regards,
Hans
BTW: if anyone has spare hardware for testing the radio-maestro/tea575x-tuner,
then I'm interested.

I guess simply porting radio-maestro codes into snd-es1968 would work
without much hustles, and it's a bit safe way to go for now; smaller
changes have less chance for breakage, and as little people seem using
this driver, it'd be better to take a safer option, IMO.
If we have active testers for both devices, it's nicer to go forward
to clean-up works indeed, though.

I assume someone has hardware since someone reported this breakage. So try
to use tuner-tea575x for the es1968. It shouldn't be too difficult.
Additional cleanup should probably wait until we find a tester for the
fm801 as well.
I don't like the idea to duplicate code.

We can try at least, yes...

My concern is that having both testers might be not easy, if we need
to change something in tea575-tuner side.
(We have already the same code, so porting it doesn't increase the code
size :) Anyway I agree to unify in a long term. Let's see whether
tea-575x works as is.

I have the hardware - both ES1968 (SF64-PCE2-04) and FM801 cards (SF64-PCR)
with these tuners. I remember fixing mute in tea5757x-tuner back in 2009
(testing it on SF64-PCR).
> I don't like the idea to duplicate code.
I don't like that either. I've done a quick hack - copied radio support from
fm801 and radio_bits_get() and radio_bits_set() from radio-maestro to es1968
and it seems to basically work.
Now I just need some more time to finish it, then move everything good from
radio-maestro to tea575x-tuner and delete radio-maestro.
IIRC, the TEA5757 tuner is also present on at least one ISA radio card -
SF16-FMR2 (which I also have).

Interesting. I have a bunch of isa radio cards myself and I am planning a
major cleanup of those isa drivers. I might get back to you for testing.

Improve tea575x-tuner with various good things from radio-maestro:
- extend frequency range to 50-150MHz
- fix querycap(): card name, CAP_RADIO
- improve g_tuner(): CAP_STEREO, stereo and tuned indication
- improve g_frequency(): tuner index checking and reading frequency from HW
- improve s_frequency(): tuner index and type checking

- * + No volume control - only mute/unmute - you have to use Aux line volume
- * control on Maestro card to set the volume
- * + Radio status (tuned/not_tuned and stereo/mono) is valid some time after

Applied these 3 patches now to topic/misc branch of sound git tree
(i.e. for 2.6.40 kernel).
I leave the removal of radio-maestro to v4l guys, as this is fairly
independent.

I prefer if you could also add it on your tree, as we want to make sure that
this patch will be applied together with the patches that moved Maestro
support into the es1968 driver.
I have no means to test if the es1968 changes work with a Maestro radio (as I
don't have this hardware), but I'm OK with this change. So:

BTW, can you run the v4l2-compliance utility for the two boards that use
this radio tuner?
This utility is part of the v4l-utils repository (http://git.linuxtv.org/v4l-utils.git).
Run as 'v4l2-compliance -r /dev/radioX -v2'.
I'm sure there will be some errors/warnings (warnings regarding G/S_PRIORITY
are to be expected). But I can use it to make a patch for 2.6.40 that fixes
any issues.
Regards,
Hans

OK, I removed it in my tree now.

The output is the same for both fm801 and es1968 (see below). Seems that
there are 4 errors:
1. multiple-open does not work
2. something bad with s_frequency
3. input functions are present
4. no extended controls

I will fix this. Once 2.6.39-rc1 is released I can make a patch fixing this.

Hmm, S_FREQUENCY apparently fails to check for valid frequency values.
Can you take a quick look at the code?

ENUMINPUT/G/S_INPUT are not allowed for radio devices. These ioctls are specific
for video. 90% of all radio driver use it, though :-)
I'll fix this when I go through all radio drivers.

I'll fix this as well. The drivers needs to be converted to the control
framework.

The driver code is OK. But there is a bug in v4l2-test-input-output.cpp at
line 214:
if (ret)
return fail("set rangehigh+1 frequency did not return EINVAL\n");
There should be "if (ret != EINVAL)" instead of "if (ret)".

Grrr. I hate it when test code has bugs :-)
Thanks for finding this. I've fixed it in the code and pushed it to the v4l-utils
repository.
