If so, the module 19 will be called snd-soc-core. 20 21if SND_SOC 22 23config SND_SOC_CACHE_LZO 24 bool "Support LZO compression for register caches" 25 select LZO_COMPRESS 26 select LZO_DECOMPRESS 27 ---help--- 28 Select this to enable LZO compression for register caches. 29 This will allow machine or CODEC drivers to compress register 30 caches in memory, reducing the memory consumption at the 31 expense of performance. If this is not present and is used 32 the system will fall back to uncompressed caches. 33 34 Usually it is safe to disable this option, where cache 35 compression in used the rbtree option will typically perform 36 better. 37 38config SND_SOC_AC97_BUS 39 bool 40 41# All the supported SoCs 42source "sound/soc/atmel/Kconfig" 43source "sound/soc/au1x/Kconfig" 44source "sound/soc/blackfin/Kconfig" 45source "sound/soc/davinci/Kconfig" 46source "sound/soc/ep93xx/Kconfig" 47source "sound/soc/fsl/Kconfig" 48source "sound/soc/imx/Kconfig" 49source "sound/soc/jz4740/Kconfig" 50source "sound/soc/nuc900/Kconfig" 51source "sound/soc/omap/Kconfig" 52source "sound/soc/kirkwood/Kconfig" 53source "sound/soc/mid-x86/Kconfig" 54source "sound/soc/pxa/Kconfig" 55source "sound/soc/samsung/Kconfig" 56source "sound/soc/s6000/Kconfig" 57source "sound/soc/sh/Kconfig" 58source "sound/soc/tegra/Kconfig" 59source "sound/soc/txx9/Kconfig" 60 61# Supported codecs 62source "sound/soc/codecs/Kconfig" 63 64endif # SND_SOC 65 66
