/*
* alignment [IN]
* Alignment for the allocation.
* Should be at least the requested page size.
*
* allocSize [IN]
* Size of the FLA VA.
*
* pageSize [IN]
* Requested page size. Can be any of the NV_MEMORY_FABRIC_PAGE_SIZE_*
*
* allocFlags [IN]
* Can be any of the NV00F8_ALLOC_FLAGS_*
* DEFAULT (sticky)
* The FLA -> PA mappings will be stuck to the object, i.e, once the mapping is created
* there is no way to unmap it explicitly.
* The FLA object must be destroyed to release the mappings.
* The FLA object can't be duped or exported until it has a mapping associated with it.
* Partial FLA->PA mappings will NOT be allowed.
* FLEXIBLE_FLA
* The FLA -> PA mappings can be modified anytime irrespective of the FLA object is duped
* or exported.
* Partial FLA mappings are allowed.
* FORCE_NONCONTIGUOUS
* The allocator may pick contiguous memory whenever possible. This flag forces the
* allocator to always allocate noncontiguous memory. This flag is mainly used for
* testing purpose. So, use with caution.
* FORCE_CONTIGUOUS
* This flag forces the allocator to always allocate contiguous memory.
* READ_ONLY
* The FLA -> PA mappings will be created read-only. This option is only available on
* debug/develop builds due to security concerns. The security concerns are due to the
* fact that FLA access errors (a.k.a PRIV errors) are not aways context attributable.
*
* map.offset [IN]
* Offset into the physical memory descriptor.
* Must be physical memory page size aligned.
*
* map.hVidMem [IN]
* - Handle to the physical memory.
* - Must be passed so that the FLA -> GPA mapping can happen during object creation.
* - For sticky allocations, physical memory being mapped should be large enough
* (accounting map.offset) to cover the whole fabric object allocation size.
* - For flexible allocations, physical memory handle should be zero.
* - Phys memory with 2MB and 512MB pages is supported.
* - hVidMem should belong the same device and client which is allocating FLA.
*
* map.flags [IN]
* Reserved for future use.
* Clients should pass 0 as of now.
