what does CONFIG_APUS do? thats the conditional on which in_le32 is used or not. AFAIK, readl is not supposed to have endian-characteristics, but if true, that would make the non-APUS ppc version totally wrong. on x86: #define __io_virt(x) ((void *)(x)) #define readl(addr) (*(volatile unsigned int *) __io_virt(addr)) #define writel(b,addr) (*(volatile unsigned int *) __io_virt(addr) = (b)) --p _______________________________________________________________ Don't miss the 2002 Sprint PCS Application Developer's Conference August 25-28 in Las Vegas -- http://devcon.sprintpcs.com/adp/index.cfm _______________________________________________ Alsa-devel mailing list [EMAIL PROTECTED] https://lists.sourceforge.net/lists/listinfo/alsa-devel
