Assigning System-wide DMA memory (Windows® only)

Note

This feature can only be used when DeviceConfigure is started with elevated user privileges since the DMA memory configuration requires to access a special section of the Windows Registry and the invocation of command line tools requiring elevated privileges!

The mvHYPERION driver support to reserve system wide DMA memory. This memory will then exclusively be accessible by the mvHYPERION driver an no longer by the operating system so only chunks of memory should be reserved that are not essential for the operating system or the application.

Once done however this memory can be accessed very efficiently by the device driver so it's usage if highly recommended. In order to do so the menu entry "Action → Update Permanent DMA Buffer Size" can be used.

Once the desired amount of memory has been entered and confirmed the system must be restarted.
