All of these source files do #include <sound/core.h>, but these missing/implicit functions are conditional:
#ifdef CONFIG_ISA_DMA_API #define DMA_MODE_NO_ENABLE 0x0100
void snd_dma_program(unsigned long dma, unsigned long addr, unsigned int size, unsigned short mode); void snd_dma_disable(unsigned long dma); unsigned int snd_dma_pointer(unsigned long dma, unsigned int size); #endif
so should these drivers all depend on ISA_DMA_API ?
Yes, these are ISA sound cards, so they must have CONFIG_ISA and CONFIG_ISA_DMA. Although CONFIG_SND_SB8_DSP, CONFIG_SND_SB16_DSP and CONFIG_SND_WSS_LIB have no direct dependency, but the drivers selecting these are all in "if SND_ISA" in sound/isa/Kconfig.
or should only pieces of each driver depend on ISA_DMA_API ?
I wonder which configuration makes it possible. Did you see a similar problem with randconfig?
thanks,
