Date: Thu, 8 Dec 2011 09:40:37 +0530 [thread overview]
Message-ID: <4EE038BD.7010705@st.com> (raw)
Hi Dan/Vinod
I am looking to implement scatter/gather interface for mem to mem transfers.
But before that, i wanted to know your feedback about it.
In my case, i have memory scattered in pages and performance is not good, if
i submit transfers page by page.
If you are Okay with the idea, i can implement it and submit soon.
