[alsa-devel] Alsa Driver Scarlett
Hello,
I've come across this earlier post from the alsa-devel mailing list : http://thread.gmane.org/gmane.linux.alsa.devel/126241/focus=126682
It deals with a kernel patch made to support some Focusrite Scarlett hardware, you can find the github project page is here : https://github.com/smilingthax/alsa-driver_scarlett
I would be really interested in it being integrated into alsa. Unfortunately, it appears that the original developer of this patch cannot put any time into such a thing. Since I'm not skilled enough to perform this integration, i wanted to know if anyone was willing to work on this ? I own a Focusrite Scarlett 18i20 and can perform any test to help.
Hey Eugène,

I'm using a Scarlett 18i8. I'm currently using an older kerner for which the patch applies, but I'm going to have to upgrade at some point, so I'm in the same boat.
I guess I'll need to find the time to port the patch to a recent kernel when I upgrade, unless someone else does it first.

The patch still works on our recent kernels (we are on debian testing with a 3.14-2 kernel), atm there is no porting necessary. I can also confirm that the driver has no known issues on our systems (we use a couple of Scarlett 18i20 in different configurations). It would be great, though if the patch could get integrated into alsa. At the moment it is quite painful for our students with linux laptops as they have to reapply the patch on every upgrade.

Oh, I see. I'm all for integrating this patch into mainline. But I have never done such a thing, so I don't know how much effort it would be. I guess it would be a simple thing to do for a routine Alsa developer. Anyone? :]

A tip could be to use the DKMS infrastructure, which recompiles itself on kernel upgrades.

Well, as a first check: Do we have means to contact Tobias Hoffman, and possibly other contributors? Having their sign-off would be a good start...

You could reach the patch author via github, I guess.

Well, I wonder how, as there is no email address. There's also a GitHub issue about mainlining the driver (#1), in which I suggested the first steps towards submission.
I think David is right - we need at least some sort of acknowledgment from Tobias to include his code in the kernel.

Hi Tobias,
I believe you are the author of the repository at https://github.com/smilingthax/alsa-driver_scarlett.
Your Scarlett driver is reported to be working fine, and there are some requests (see below) to get the driver into mainline Linux. Is this something you would be interested in helping out with?
Regards, David

just joined this mailing list yesterday for exactly the same reason: Bought an Focusrite Scarlett 6i6, and while it works with jack, it doesn't show up in the alsa mixer. As I understand, this patch should also work better for the 6i6, so I'd also very much appreciate getting this patch into the kernel.
If you need a tester for the 6i6 device, I'd happily try a patch.
Greetings, Dominik

I'm all for including the driver into mainline, but I do not have any time to go through N iterations of a patch to get it there.
I *might* be able to do a initial cleaned up version against tiwai's for-next in the next few days, if that helps.
Other than that, I will happily (try to) answer questions about the code.
Tobias

Ok, thanks for the update!
As I looked through the patches I noticed Robin Gareus (now cc:ed) were also the author of these patches, I assume you're okay with upstreaming it too, Robin?
There seem to be these "main" patches:
* Initial code for 18i6 mixer (Robin) * Added log scale meters for 18i6 mixer (Robin) * Added code for 18i8 and "big rewrite" (Tobias) * Added code for 18i20 (Tobias) * Added code for 8i6 (Tobias) * Added code for 6i6 (Tobias)
...the rest of the patches are fixups which can be squashed into the existing patches when mainlining.
I could commit to do this squashing, run the remaining patches through checkpatch and submit the result on alsa-devel. I have no hw to test with though.
The big rewrite probably means that the rewrite patch should be squashed with the initial patch too, and list both of you as authors on the resulting patch. (Btw, what's the Linux kernel standard for that? To add a co-authored-by?)
Regards, David
