<div>Hi all</div>
<div>A very limited (1-2MB) address space is mapped to dma_alloc() in ARM architecture..what if a DMA transfer of >2MB is needed at a time? As DMA transfer starts asynchronously..CPU relinquishes data buses..so CPU cant control. So the excess data which is >2MB will be overflown or lost..So how this large data transfers are being managed?<br clear="all">
