+/**
+ * @brief Creates an object that manages allocating OS memory
+ *
+ * Creates an object that provides an interface to allocate OS memory and
+ * have it mapped into the Mali virtual memory space.
+ *
+ * The object exposes pointers to
+ * - allocate OS memory
+ * - allocate Mali page tables in OS memory
+ * - destroy the object
+ *
+ * Allocations from OS memory are of type mali_physical_memory_allocation
+ * which provides a function to release the allocation.
+ *
+ * @param max_allocation max. number of bytes that can be allocated from OS memory
+ * @param cpu_usage_adjust value to add to mali physical addresses to obtain CPU physical addresses
+ * @param name description of the allocator
+ * @return pointer to mali_physical_memory_allocator object. NULL on failure.
