ALSA: seq: Fix CONFIG_SND_SEQ_MIDI dependency

2017-08-11T07:51:41Z

The commit 0181307abc1d ("ALSA: seq: Reorganize kconfig and build") rewrote the dependency of each sequencer module in a standard way, but there was one change applied mistakenly: CONFIG_SND_SEQ_MIDI isn't enabled properly by CONFIG_SND_RAWMIDI. I seem to have changed the wrong one instead, CONFIG_SND_SEQ_MIDI_EMUL, which is eventually reverse-selected by CONFIG_SND_SEQ_MIDI itself. This ended up the lack of snd-seq-midi module as reported below. The fix is to put def_tristate properly to CONFIG_SND_SEQ_MIDI instead of *_MIDI_EMUL entry.

ALSA: seq: Allow the modular sequencer registration

2017-06-12T06:43:33Z

Many drivers bind the sequencer stuff in off-load by another driver module, so that it's loaded only on demand. In the current code, this mechanism doesn't work when the driver is built-in while the sequencer is module. We check with IS_REACHABLE() and enable only when the sequencer is in the same level of build. However, this is basically a overshoot. The binder code (snd-seq-device) is an individual module from the sequencer core (snd-seq), and we just have to make the former a built-in while keeping the latter a module for allowing the scenario like the above. This patch achieves that by rewriting Kconfig slightly. Now, a driver that provides the manual sequencer device binding should select CONFIG_SND_SEQ_DEVICE in a way as select SND_SEQ_DEVICE if SND_SEQUENCER != n Note that the "!=n" is needed here to avoid the influence of the sequencer core is module while the driver is built-in. Also, since rawmidi.o may be linked with snd_seq_device.o when built-in, we have to shuffle the code to make the linker happy. (the kernel linker isn't smart enough yet to handle such a case.) That is, snd_seq_device.c is moved to sound/core from sound/core/seq, as well as Makefile. Last but not least, the patch replaces the code using IS_REACHABLE() with IS_ENABLED(), since now the condition meets always when enabled. Signed-off-by: Takashi Iwai

ALSA: seq: Reorganize kconfig and build

2017-06-09T20:10:06Z

This is a slightly intensive rewrite of Kconfig and Makefile about ALSA sequencer stuff. The first major change is that the kconfig items for the sequencer are moved to sound/core/seq/Kconfig. OK, that's easy. The substantial change is that, instead of hackish top-level module selection in Makefile, we define a Kconfig item for each sequencer module. The driver that requires such sequencer components select exclusively the kconfig items. This is more straightforward and standard way. Signed-off-by: Takashi Iwai

ALSA: clean up the logic for building sequencer modules

2009-05-29T09:49:42Z

Instead of mangling the CONFIG_* variables in the makefiles over and over, set a few helper variables in Kconfig. Signed-off-by: Michal Marek Signed-off-by: Takashi Iwai
