>Um, so 2.6.34 to 2.6.32 causes this spike in usage? Definitely yes. > What is the SWIOTLB (PCI-DMA32) usage between these two kernels I don't understand. What do you mean? The only difference is that I call up the swiotlb differently: On pvops: iommu=soft On rebased: swiotlb=32,force BTW: changing to 64,force doesn't make a difference. I attached a normal boot log of both kernels. > and are the drivers (budget_...) the same version? No, but a quick diff between the two source trees offer only minor changes that from the first look do not seem to be related to DMA or whatever. Carsten.
