Tonello" <eu@felipetonello.com> On this second version I made sure that the patch series can be bisected. Also, since HDA codec has it's own jack infrastructure, I just disabled the support of the core ALSA jack in it. Why? Because it's causing duplication of controls, although the input events works fine. A HDA codec developer might give us more information about it. Patch 1) Is the actual implementation and fixes for users that uses the API. Patch 2) Name fixes. Just to make sure no jack has " Jack" duplicated at the end of its name. Felipe F.

Tonello, Jaroslav Kysela, Takashi Iwai, Mark Brown, linux-kernel From: "Felipe F. Tonello" <eu@felipetonello.com> This patch adds jack support for ALSA KControl. This support is necessary since the new kcontrol is used by user-space daemons, such as PulseAudio(>=2.0), to do jack detection.) Also, HDA's CONFIG_SND_HDA_INPUT_JACK is disabled because it causes to use standard snd_jack_new() to create jacks. This can cause conflict since this codec creates jack controls directly. It makes sure that all codecs using ALSA jack API are updated to use the new API. Signed-off-by: Felipe F.

I got confused with another talk we had previously, that's why I end up doing as an int. I will wait for more comments about these patches and will submit a v3.

Tonello @ 2013-08-09 6:21 UTC (permalink / raw) To: alsa-devel; +Cc: Takashi Iwai, linux-kernel, Mark Brown, Felipe F. Tonello From: "Felipe F. Tonello" <eu@felipetonello.com> This patch adds jack support for ALSA KControl. This support is necessary since the new kcontrol is used by user-space daemons, such as PulseAudio(>=2.0), to do jack detection.) Also, HDA's CONFIG_SND_HDA_INPUT_JACK is disabled because it causes to use standard snd_jack_new() to create jacks. This can cause conflict since this codec creates jack controls directly. It makes sure that all codecs using ALSA jack API are updated to use the new API. Signed-off-by: Felipe F.

Well, while this is a good move forward, this patch is a bit too intrusive as a single patch. It breaks way too many. "Break then fix" is no good attitude, especially when it's just something for future. So, in general, I prefer a way with more gradual changes.

That's why you need to modify so many patches in a single patch. Try to create a new function doing this and keep the old API and behavior as is. Then adapt / replace with the new API gradually. And in the last step, you can obsolete the former API. Or, at least keep snd_sock_jack_new() as is without additional index but just use idx=0. Then a half of the whole patch can be reduced. Above all, the multiple indices don't work anyway with the snd_jack stuff in the current form.

Yes, I thought of it, too. But there are some funky names like "hook_switch". Also, there is "Headphones", too. So, IMO, the function should accept a special name for the input-jack for compatibility reason while creating standard names for kjack, or so...

I agree with you, but unfortunately I had to do that due the non-standard way that jacks are been handled in the kernel and reported to user-space. I believe this is a classic case where we need a well defined kernel API to user-space. I'm not necessarily saying about internal kernel API/ABI, but the one which is exported to user-space. And to be honest, it's kind common to see internal API's been changed. And that's the reason jack detection only work, out of the box, with Intel's HD-audio. Which I think it's pretty bad in the stage we are. More and more embedded running PulseAudio and other core user-space daemons.

Why? Can't we just fix those names in those codecs? As You see in my second patch, only few of them are using weird names. I know that this will potentially break user-space, but the trade off is not to standardize the Jack API. What do you think?

The same logic can be applied to HD-audio input jack controls, too. But, don't get me wrong: I'm not against the action itself, the removal of input jack support in HD-audio. I myself did propose this once ago. Again, what's missing in your approach is the proper process. An easier (or lazier) way to manage this problem would be: - Think whether removal of input-jack support is really needed for HD-audio; for example, if you integrate snd_jack stuff to support both input-jack and kctl jack, HD-audio driver can use it solely instead of calling snd_kctl stuff. Then both input and kctl jacks will be supported automagically. - If it's still easier to handle kctl jacks without input jacks in HD-audio, propose the removal at first on the list, get the general consensus. Then put the removal patch in your series at first. - Try to keep snd_jack_new() intact but create a new API function for creating both input and kctl jacks. This would accept two different name strings, one for input jack and one for kctl, with an additional index, if needed. The different names are needed not to break the things. - Replace snd_soc_jack_new() with the new function, but you don't have to add the index argument yet at this point. The handling of multiple input-jack instances with indices isn't defined yet, so the simplest solution would be just to skip the multiple indices. It should be good enough for ASoC. - Replace snd_jack_new() in the rest. - If wanted, obsolete snd_jack_new(), but keep only the new API.

We've also got extcon based reporting to consider, having a single place where all the userspace interfaces are implemented will mean we can just add that. This is why I put everything in jack.c in the first place :( [-- Attachment #1.2: Digital signature --] [-- Type: application/pgp-signature, Size: 836 bytes --] [-- Attachment #2: Type: text/plain, Size: 0 bytes --] ^ permalink raw reply [flat|nested] 14+ messages in thread
