Dmitry Osipenko 92cd14408b media: staging: media: tegra-vde: Defer dmabuf's unmapping ... Frequent IOMMU remappings take about 50% of CPU usage because there is quite a lot to remap. Defer dmabuf's unmapping by 5 seconds in order to mitigate the mapping overhead which goes away completely and driver works as fast as in a case of a disabled IOMMU. The case of a disabled IOMMU should also benefit a tad from the caching since CPU cache maintenance that happens on dmabuf's attaching takes some resources.
