Subject[PATCH 0/2] dmaengine: Add scatter-gathered memset support
Date
Hi Vinod,

Here is a patch serie that adds a new dmaengine operation for
scatter-gathered memset.

Indeed, doing a memset over a discontiguous buffer is quite
inefficient at the moment, since you have to create and submit each
chunk separately, which might result in a huge list of transfers,
while some controllers can handle that just fine.

Let me know what you think,
Maxime
