bounce_sg and sg in mmc_queue

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hello:

Could anyone tell me in struct mmc_queue, what is the difference between 'struct scatterlist *bounce_sg' and 'struct scatterlist *sg' is?

I see 'bounce_sg' get used to copy data from/to the buffer upon a host read/write operation so I assume 'bounce_sg' points to the most recent data from a host controller read/write operation.

Thanks for the help.
