2013-08-15ALSA: core: allow SND_DMAENGINE_PCM use from modulesDaniel Mack1-1/+1
When users of SND_DMAENGINE_PCM are built as module, the config symbol SND_DMAENGINE_PCM must be tristate, otherwise the linker will fail. Signed-off-by: Daniel Mack <zonque@gmail.com> Reported-by: Fengguang Wu <fengguang.wu@intel.com> Signed-off-by: Mark Brown <broonie@linaro.org>
2013-08-15ALSA: move dmaengine implementation from ASoC to ALSA coreDaniel Mack1-0/+3
For the PXA DMA rework, we need the generic dmaengine implementation that currently lives in sound/soc for standalone (non-ASoC) AC'97 support. Move it to sound/core, and rename the Kconfig symbol. Signed-off-by: Daniel Mack <zonque@gmail.com> Signed-off-by: Mark Brown <broonie@linaro.org>
2013-05-24ALSA: Add kconfig to specify the max card numbersTakashi Iwai1-0/+9
Currently ALSA supports up to 32 card instances when the dynamic minor is used. While 32 cards are usually big enough for normal use cases, there are sometimes weird requirements with more card support. Actually, this limitation, 32, comes from the index option, where you can pass the bit mask to assign the card. Other than that, we can actually give more cards up to the minor number limits (currently 256, which can be extended more, too). This patch adds a new Kconfig to specify the max card numbers, and changes a few places to accept more than 32 cards. The only incompatibility with high card numbers would be the handling of index option. The index option can be still used to pass the bitmask for card assignments, but this works only up to 32 slots. More than 32, no bitmask style option is available but only a single slot can be specified via index option. Signed-off-by: Takashi Iwai <tiwai@suse.de>

2009-07-08ALSA: Fix SG-buffer DMA with non-coherent architecturesTakashi Iwai1-0/+4
Using SG-buffers with dma_alloc_coherent() is often very inefficient on non-coherent architectures because a tracking record could be allocated in addition for each dma_alloc_coherent() call. Instead, simply disable SG-buffers but just allocate normal continuous buffers on non-supported (currently all but x86) architectures. Signed-off-by: Takashi Iwai <tiwai@suse.de>

2008-08-29sound: make OSS sound core optionalTejun Heo1-0/+1
sound/sound_core.c implements soundcore.ko and contains two parts - sound_class which is shared by both ALSA and OSS and device redirection support for OSS. It's always compiled when any sound support is enabled although it's necessary only when OSS (the actual one or emulation) is enabled. This is slightly wasteful and as device redirection always registers character device region for major 14, it prevents alternative implementation. This patch introduces a new config SOUND_OSS_CORE which is selected iff OSS support is actually necessary and build the OSS core part conditionally. If OSS is disabled, soundcore merely contains sound_class but leaving it that way seems to be the simplest approach as otherwise sound_class should be in ALSA core file if OSS is disabled but should be in soundcore if OSS is enabled. Also, there's also the user confusion factor. Signed-off-by: Tejun Heo <tj@kernel.org> Signed-off-by: Takashi Iwai <tiwai@suse.de> Signed-off-by: Jaroslav Kysela <perex@perex.cz>
2008-07-29ALSA: Build jack detectionMark Brown1-0/+6
Since jack detection requires the input subsystem which may not be desired on small systems it is not built unless required by a driver that is being built. Drivers using jack detection should use a pattern like this: config SND_FOO tristate "..." ... select SND_JACK if INPUT=y || INPUT=SND to ensure that the jack detection API is enabled if the input subsystem is. If the input subsystem is not enabled then a stub version of the API is provided.

2005-04-16Linux-2.6.12-rc2Linus Torvalds1-0/+133
Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
