[alsa-devel] OSS4 X-Fi driver port to ALSA
Hi, On Feburary 1, 4Front released their XFi driver to the public. Is anyone looking into porting this? If not, I will give it a try soon enough. It seems to not require any firmware at all too. William

Please not that the hwaccess.* files are apparently not GPL licensed.

Because the driver doesn't support the interesting features (hardware mixing, DSP). Regards, Clemens

Interesting. But it's not released under GPL or so, I guess? Takashi

Hi Takashi! It's released in the OSS4 GPL tarball. The hwaccess.* files don't have a header, but I think I can probably get them cleaned up. William

I might be able to comment on this once I get the datasheets from Creative in the next week or so. James

Good news. Can we get a copy? Or you signed NDA? Thanks, Jaroslav ----- Jaroslav Kysela <perex@perex.cz> Linux Kernel Sound Maintainer ALSA Project, Red Hat, Inc.

Just an update. No datasheets have arrived. James

Will anyone start porting from OSS? It doesn't look like so much amount of codes... Takashi

I intend to port from OSS soon. I just need to learn more about the driver's internals. William

Good to hear! Just pop up on this ML if you have questions. Takashi

I now had some datasheets for the x-fi. I think the first thing we should do is create a GPL version of the header files. Shall I do that task? James

Yes! That sounds great. I have two different X-Fi cards, so let me know when you have the headers ready, and we can merge them into the OSS4 driver as an initial effort. That way everything we have is theoretically free. I'll have to recheck what is in OSS4 though. William

Why put it into OSS4? I would put it into the alsa-driver hg repository as a new driver. The header would go into the alsa-driver include dir. Then, start by writing a new alsa driver to just playback to the front speakers with possibly a volume control. Once we have that in alsa-driver working, we can then add features gradually. I don't think we will be able to use the OSS4 code, that is only really useful as a reference. James

I concur that putting it into OSS4 is a waste of time. There are other files marked as not being GPL. So, we need to start from scratch. William
