ALSA: add HAS_IOPORT dependencies

2023-05-22T14:43:47+00:00

In a future patch HAS_IOPORT=n will result in inb()/outb() and friends not being declared. We thus need to add HAS_IOPORT as dependency for those drivers using them.

m68k: coldfire: drop ISA_DMA_API support

2022-05-16T03:18:30+00:00

After a build regression report, I took a look at possible users of CONFIG_ISA_DMA_API on m68k and found none, which Greg confirmed. The CONFIG_GENERIC_ISA_DMA option in turn is only needed to implement ISA_DMA_API, and is clearly not used on the platforms with ISA support. The CONFIG_ISA support for AMIGA_PCMCIA is probably also unneeded, but this is less clear. Unlike other PCMCIA implementations, this one does not use the drivers/pcmcia subsystem at all and just supports the "apne" network driver. When it was first added, one could use ISA drivers on it as well, but this probably broke at some point. With no reason to keep this, let's just drop the corresponding files and prevent the remaining ISA drivers that use this from getting built. The remaining definitions in asm/dma.h are used for PCI support.

media: sound, isapnp: allow building more drivers with COMPILE_TEST

2018-04-20T14:53:45+00:00

Drivers that depend on ISAPNP currently can't be built with COMPILE_TEST. However, looking at isapnp.h, there are already stubs there to allow drivers to include it even when isa PNP is not supported. So, remove such dependencies when COMPILE_TEST.

media: sound, media: allow building ISA drivers it with COMPILE_TEST

2018-04-20T14:53:21+00:00

All sound drivers that don't depend on PNP can be safelly build with COMPILE_TEST, as ISA provides function stubs to be used for such purposes. As a side effect, with this change, the radio-miropcm20 can now be built outside i386 with COMPILE_TEST. It should be noticed that ISAPNP currently depends on ISA. So, on drivers that depend on it, we need to add an explicit dependency on ISA, at least until another patch removes it. Acked-by: Takashi Iwai Signed-off-by: Mauro Carvalho Chehab

ALSA: seq: Allow the modular sequencer registration

2017-06-12T06:43:33+00:00

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: synth: Select snd-emux-synth explicitly

2017-06-09T20:10:06+00:00

Instead of the non-standard way to enable the build of snd-emux-synth module inside Makefile, rewrite Kconfig to select the item explicitly from each driver (sbawe and emu10k1). This is the standard way. Signed-off-by: Takashi Iwai
