So does that mean we need to allocate different dma handles for each individual chunk (assuming each chunk has different sizes and alignment requirement),dma_alloc the memory and bind the vaddr to the above allocated handle to get the cookies?
Yep.
instance if i had 36 diff chunks so i would have to allocate 36 diff handles? Can i reuse the same handle after i have allocated one chunk?
You can re-cycle handles once they are unbound. You cannot bind the same handle multiple times.
