Dear all: There are some questions about dma api when I read the document: 1. should dma apis in dma_mapping.h be implemented by different arch? 2. if above 1 is correct, I should get any result when I grep "dma_map_ops" in mips arch. but I get nothing. 3. if above 1 is wrong, why I can grep 'dma_map_ops' in arch/x86? appreciate your help, miloody -- To unsubscribe from this list: send an email with "unsubscribe kernelnewbies" to ecartis@xxxxxxxxxxxx Please read the FAQ at http://kernelnewbies.org/FAQ
