For Barman to be able to use either of the RAM buffer modes, you must provide the RAM buffer on the target device. The RAM buffer is a dedicated, contiguous area of RAM that Barman can write data to.
On multiprocessor systems, the RAM buffer must be at the same address for all processors. It is your responsibility to allocate memory for the RAM buffer, either statically or dynamically.
This section describes how to collect profiling data using the RAM buffer on the target device.
