/* Shared synchronisation code for ring buffers
- *
+ *
* The next three functions are to create/delete/use the OpenGL synchronisation.
* ARB_sync (OpenGL 3.2) is used and required.
- *
+ *
* To reduce overhead, the complete buffer is splitted up into SYNC_POINTS chunks.
* For each of this chunks, there is a fence which checks if this chunk is still in use.
- *
+ *
* As our API allows to alloc more memory then it has to use, we have to catch how much is already written.
- *
+ *
* m_iterator - writing position
* m_free_iterator - last position checked if free
* m_used_iterator - last position known to be written
- *
+ *
* So on alloc, we have to wait for all slots between m_free_iterator and m_iterator (and set m_free_iterator to m_iterator afterwards).
- *
+ *
* We also assume that this buffer is accessed by the gpu between the Unmap and Map function,
* so we may create the fences on the start of mapping.
* Some here, new fences for the chunks between m_used_iterator and m_iterator (also update m_used_iterator).
- *
+ *
* As ring buffers have an ugly behavoir on rollover, have fun to read this code ;)
