excuse me I hate to bother everyone but I have a question about DMA of PCI bridge
Now I attempt to fetch data from peripheral device to SDRAM, and it has been successed but how the DMA controller know the data bandwidth of src and dest. for example, if i get a 16bits data with a 32bits bus, and other 16bits will be set high and data will fetched into cache line of dma, then it will be wrote to 32bits SDRAM. i guess the data will be wrong, isn't ? please give me some advices. thank you -- View this message in context: http://www.nabble.com/question-%3A-DMA-of-PCI-bridge-tp23628338p23628338.html Sent from the linuxppc-dev mailing list archive at Nabble.com. _______________________________________________ Linuxppc-dev mailing list Linuxppc-dev@ozlabs.org https://ozlabs.org/mailman/listinfo/linuxppc-dev
