Default SW IOTLB allocation is 64MB ... how much should we see used per ioc?
Kamelesh: You could try increasing the amount of sw iotlb space available by booting with a swiotlb=131072 argument (argument value is the number of 2K slabs to allocate ... 131072 would give you four times as much space as the default allocation).
