Detailed Description
template<class T>
class gem5::DmaVirtDevice::DmaVirtCallback< T >
Wraps a std::function object in a DmaCallback.
Much cleaner than defining a bunch of callback objects for each desired behavior when a DMA completes. Contains a built in templated buffer that can be used for DMA temporary storage.
