Re: Is there plans to support SiS7019?

[Peter Zubaj]

Hi,

I think (and from alsa source), looks like it is not supported for now.
Maybe it is similiar to 7018, maybe someone could try to add it to
trident module.

Well, the number looks very similar.  ;-)

You can try to go into the alsa-kernel/pci/trident directory and
replace all occurrences of 7018 with 7019 (70 lines in three files).
If the driver works with your card after recompiling, it is similar.

published anywhere?

If the driver can just pretend it's an 7018, then it's trival.

If it's an AC'97 controller then we should look at the intel8x0
instead ...

We obtained it from SiS. Since they have stopped development on this
driver, they have agreed to provide the details to third parties for
fixing the problems. Their driver is OSS based, though.

It is an AC'97 controller. Under OSS, SiS supplied driver was stacked
over modules soundcore and ac97_codec. Now does the scope of work
change? Will it be easy to modify intel8x0 to work with it? Since
I have not done this stuff before, can you please point out the
right path?

The question is whether SIS7019 is an AC97 chip, or it's the one to
control other AC97 chips.  If it's former, you should have another PCI
entry for the controller (check lspci).  In the latter case, you can
try snd-trident module with changes of pci id table from SIS7018 to
SIS7019.

Hi!

Thanks for the quick response.

SiS7019 controls other AC97 chips. The board which we have designed
uses Real Tech's ALC202A (four channel) and ALC650 (six channel).
Now what should I change in
.../alsa-driver-1.0.0rc2/alsa-kernel/pci/trident/trident.c?
I see following entries with SiS7018 mentioned:

<snip>

MODULE_DESCRIPTION("Trident 4D-WaveDX/NX & SiS SI7018");

<snip>

MODULE_DEVICES("{{Trident,4DWave DX},"
                "{Trident,4DWave NX},"
                "{SiS,SI7018 PCI Audio},"
                "{Best Union,Miss Melody 4DWave PCI},"
                "{HIS,4DWave PCI},"
                "{Warpspeed,ONSpeed 4DWave PCI},"
                "{Aztech Systems,PCI 64-Q3D},"
                "{Addonics,SV 750},"
                "{CHIC,True Sound 4Dwave},"
                "{Shark,Predator4D-PCI},"
                "{Jaton,SonicWave 4D},"
                "{Hoontech,SoundTrack Digital 4DWave NX}}");

<snip>

static struct pci_device_id snd_trident_ids[] = {
        { 0x1023, 0x2000, PCI_ANY_ID, PCI_ANY_ID, 0, 0, 0, },   /* Trident
4DWave DX PCI Audio */
        { 0x1023, 0x2001, PCI_ANY_ID, PCI_ANY_ID, 0, 0, 0, },   /* Trident
4DWave NX PCI Audio */
        { 0x1039, 0x7018, PCI_ANY_ID, PCI_ANY_ID, 0, 0, 0, },   /* SiS
SI7018 PCI Audio */
        { 0, }
};

<snip>

There are few more instances where related data structures are used
in the code. In the declarations shown above, what changes should I
make? Will changing the name part from 7018 to 7019 will be enough?

Thanks.

No, just change snd_trident_ids[] entry for 7018 to 7019's one (maybe
0x7019?).  Also, in trident_main.c, you need to change the line 3546

	trident->device = (pci->vendor << 16) | pci->device;

to
	trident->device = TRIDENT_DEVICE_ID_SI7018;

You can leave MODULE_* stuffs as they are.

Thanks Takashi for the suggestions. But it is not working.

I made the changes as mentioned above. I am using alsa-driver-1.0.6a
on a board with sis7019 along with AD1881A. The configuration options
were
--with-cards=dummy,seq-dummy,ad1848,cmipci,trident,als4000 --with-oss=yes
--with-sequencer=yes --with-debug=full --with-kernel=/usr/src/linux

The entry in modules.conf is
alias snd-card-0 snd-trident
alias sound-slot-0 snd-trident

When I did modprobe snd-trident, I got following messages in syslog

Aug 18 15:56:15 stb kernel: PCI: Found IRQ 10 for device 00:01.4

Does alsa framework need a working driver for AD1881A too which is
the codec I am using right now? Since I don't have much knowledge
about the way the AC97 controller and codec functions, this question
may be stupid.

Thanks for the help.

I don't expect alsa driver for this soon, because this is not common
hardware.
This means, this is not standard pc soundcard (or chipset). This is
used in STB, PDA, embeded systems... .

For this is more used OSS drivers, because of alsa-lib size.

PS: I wonder about existence of NetBSD patch, because I found this:

Released under NDA. List of all registers of SiS55x includeing those
for core logic, graphics, PCI IDE configuration, legacy device, LPC
bus, USB, AC97, ACPI, SMBUS, etc; an inportant document for BIOS porting.

That is true. But the problem with OSS driver is that
recording is problematic.

I think, there is no reason to try correct these unresolved symbols,
because result will by same as Takashi Iwai way.

For me looks like 7019 is diffrent from 7018. :-(

Now how much effort is required to support it in alsa if we have the
register guide with us? We also have an OSS implementation with
some bugs related to blocking read of the device.

It might help if we can take a look at the source.

Google finds a NetBSD patch at
<http://www.yasuoka.net/~yasuoka/sis7019.html>, so it's possible.

It looks that the driver must be written from scratch, because hardware is 
different from SI7018 and SI7012.

I can provide the source if you need it. But again it is for OSS
not alsa.

I want to find out how much time is needed to make the
driver from scratch if hardware specs are available. I have
no prior experience on this.

Google for "Writing an ALSA driver".  This excellent document by Takashi
Iwai gives step by step instructions with many examples from the real
code.  This should give you a pretty good idea of how long writing a
driver takes, given the specs.

I would imagine source code for an OSS driver would be even better than
having the docs, as long as the code is not obfuscated.

Thanks Lee for the right pointer. I have downloaded it. It seems to be
pretty exhaustive. I think it will help me a lot.

The code is not obfuscated and it may help us. Anyway, I am planning
to dive in and let us see what happens.

Thanks.

Hi,

These errors are not related to changes you made.

unregister_sound_special
register_sound_special

These are definied in soundcore module.

I think you need this in modules.conf too 

alias char-major-116 snd

before these lines
alias snd-card-0 snd-trident
alias sound-slot-0 snd-trident

I know that all modules to satisfy these symbols are compiled and
installed. I think my modules.conf file is not perfect. Can I get
a sample moudles.conf file? Does any such sample exist at alsa
site?

Thanks.

Re: Is there plans to support SiS7019?

[Peter Zubaj]

Hi,

The simplest I think is:

add in trident.h

#ifndef PCI_DEVICE_ID_SI_7019
#define PCI_DEVICE_ID_SI_7019		0x7019
#endif 

after 

#ifndef PCI_DEVICE_ID_SI_7018
#define PCI_DEVICE_ID_SI_7018		0x7018
#endif 

and change this
#define TRIDENT_DEVICE_ID_SI7018
((PCI_VENDOR_ID_SI<<16)|PCI_DEVICE_ID_SI_7018) 

to 
#define TRIDENT_DEVICE_ID_SI7018
((PCI_VENDOR_ID_SI<<16)|PCI_DEVICE_ID_SI_7019) 

and in trident.c change line 
{ 0x1039, 0x7018, PCI_ANY_ID, PCI_ANY_ID, 0, 0, 0, },	/* SiS SI7018
PCI Audio */
to
{ 0x1039, 0x7019, PCI_ANY_ID, PCI_ANY_ID, 0, 0, 0, },	/* SiS SI7018
PCI Audio */

If driver will load it will still print sis7018 (but this is not problem).

I made the changes as specified by you. The configuration options were
--with-cards=dummy,seq-dummy,ad1848,cmipci,trident,als4000 --with-oss=yes
--with-sequencer=yes --with-debug=full --with-kernel=/usr/src/linux

The alsa-driver-1.0.6a package is built and installed successfully.
I made following entry in /etc/modules.conf

alias snd-card-0 snd-trident
alias sound-slot-0 snd-trident

Now when I do modprobe snd-trident, I get following errors

/lib/modules/2.4.18/kernel/sound/acore/snd.o: unresolved symbol
unregister_sound_special
/lib/modules/2.4.18/kernel/sound/acore/snd.o: unresolved symbol
register_sound_special
/lib/modules/2.4.18/kernel/sound/acore/snd.o: insmod
/lib/modules/2.4.18/kernel/sound/acore/snd.o failed
/lib/modules/2.4.18/kernel/sound/acore/snd.o: insmod snd-trident failed

There is no message in syslog, even though I have set debug=full in
configure option.

The AC97 codec chip I am using is AD1881A.

Got any pointer for more debugging?

Is there plans to support SiS7019?

[Vrihad Shoonya]

I am developing some audio application for SiS55x chipset.
Its audio chipset is SiS7019. I could not find it listed
in supported card list. Is there any plans to support it?
If not, what are the reasons?

Thanking in advance.
