AMD Geode AC'97 support request
Is it possibly to add AMD CS5536 Geode companion AC'97 compatible onboard card? https://www.amd.com/content/dam/amd/en/documents/archived-tech-docs/datasheets/33238G_cs5536_db.pdf
Theoretically yes, but to make it work, a PC with such audio controller is needed for debugging.

It would be nice if ya find time and motivation. But I can live and without it for sure. I can not port linux-driver coz i'm not a coder.
OK, I'll try to find one with such audio controller in the mean time. what's your PC that equipped with this one?
Its Russian netbook Cameron Maxmedia NB-1060, the same as Russian netbook Roverbook Neo U101. Both is Chinese Malata PC-81001 netbook in origin. Its quite old and there almost none info for it available.
There is Brazil description of the same netbook https://www.hardware.com.br/artigos/proview-81001/
I have also a machine with this chipset - it is an UNO-1150GE von advantech https://support.elmark.com.pl/advantech/pdf/UNO-1150Gds.pdf. I am also not experienced in linux driver porting, but i could test some results.
Even if I have no experience with driver porting, I thought I'll give it a try. But unfortuantly some functions are missing which suspect are very important, especially snd_ac97_set_rate. I assume that is necessary to set the sample rate and thus be implemented? Do you have any hints how to handle this?
/edit: maybe we don't have to set the sample rate at all? Standard for AC97 is 48000, so maybe it doesn't have to be set.
Chiming in. I took three Geode LX boards, TR 2350 from Fujitsu-Siemens (they seems to be decommissioned Amilo A220 or something like that) - I wanted to gift them to my friends (we're all over 40, I even printed custom cases) because it seems great for retroemulation (it also has a PATA connector!). The audio is from a Realtek ALC. Obviously SBemu isn't detecting the card... let me know if something is moving on that front.
I've a couple of ALIX1/3 boards from pcengines.ch and I'm trying to work on this: https://github.com/No0ne/SBEMU/commit/59dd0764f71ae062ef6a8a425a7977fcf6298e5f But at the moment its neither finished nor working yet, it crashes after detecting the chip.

Hi, i build it under DOS and added some debugging infos. Seems that private_data is 0x0, so you get a null pointer dereference:

int snd_cs5535audio_create(struct snd_card *card,
struct pci_dev *pci)
{
struct cs5535audio *cs5535au = card->private_data;
int err;
...
geodedbg("pci_resource_start\n");
cs5535au->port = pci_resource_start(pci, 0); // <--- right here
If i find more time I might look into it. I just wanted to share my findings.
/edit: looking through the other drivers, cs5535au must be allocated manually with kzalloc, see als4000.c:912
acard = kzalloc(sizeof(*acard), GFP_KERNEL);
if (!acard)
return -ENOMEM;
card->private_data = acard;
with that, sbemu is at least starting, but i can hear nothing. Also Doom hangs at sound initialization and reports, that it getting no response from the soundcard. Maybe the audio part is not starting properly?
Cool thanks, I've currently no time to work on this until next year. Would be great if could manage to get sound out of it.
