Detailed Description

The fragments helpers.

This namespace provides helper templates to create fragments. A fragment is any structure which validates the following constraints:

• it must contain a uint32_t named head which is reserved for the usage of the GPU class.
• it must have a size_t getActualFragmentSize() method which returns the size of the fragment's payload in uint32_t units.
• the fragment payload must be immediately after the head field.

The structure may have any other field for its own usage.

Fragments are used by the GPU class to send a list of commands to the GPU. This can be done either using the sendFragment call to only send a single fragment, or by using the chain call to queue the fragments in a chain to be sent later.
