ALSA: Fix SG-buffer DMA with non-coherent architectures

2009-07-08T12:20:20Z

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

alsa: Remove special SBUS dma support code.

2008-08-29T09:14:58Z

No longer used. Signed-off-by: David S. Miller

sparc: Convert all SBUS drivers to dma_*() interfaces.

2008-08-29T09:13:15Z

And all the SBUS dma interfaces are deleted. A private implementation remains inside of the 32-bit sparc port which exists only for the sake of the implementation of dma_*(). Signed-off-by: David S. Miller

sparc: Make SBUS DMA interfaces take struct device.

2008-08-29T09:13:12Z

This is the first step in converting all the SBUS drivers over to generic dma_*(). Signed-off-by: David S. Miller

ALSA: Fix allocation size calculation in snd_dma_alloc_pages_fallback()

2008-08-25T07:57:19Z

snd_dma_alloc_pages_fallback() always tries to reduce the size in a half, but it's not good when the given size isn't a power-of-two. Check it first then try to align. Signed-off-by: Takashi Iwai Signed-off-by: Jaroslav Kysela

ALSA: Clean up SG-buffer helper functions and macros

2008-08-25T07:57:18Z

Clean up SG-buffer helper functions and macros. Helpers take substream as arguments now. Signed-off-by: Takashi Iwai Signed-off-by: Jaroslav Kysela

ALSA: Kill snd_assert() in sound/core/*

2008-08-13T09:46:35Z

Kill snd_assert() in sound/core/*, either removed or replaced with if () with snd_BUG_ON(). Signed-off-by: Takashi Iwai Signed-off-by: Jaroslav Kysela

[ALSA] Remove unneeded ugly hack for i386 in memalloc.c

2008-05-19T11:19:15Z

The hack for dma_alloc_coherent() is no longer needed on 2.6.26 since the base code was improved. Signed-off-by: Takashi Iwai Signed-off-by: Jaroslav Kysela

sound: use non-racy method for /proc/driver/snd-page-alloc creation
