我尝试使用多会话来扩展可以使用的共享内存以支持更长的上下文，但是虽然 DSP 端支持多 session 独立映射，但 host 端的 domain 级别注册限制会限制所有 session 共享的 buffer 注册总数，导致多 session 方案无法扩展，fastrpc_mmap 可能在 domain 级别有注册限制，请问是否有方案可以解决这个问题

Oh, currently I am not aware of this limitation. What is the maximum number of shared buffers in your case? Perhaps it's a limitation of FastRPC, or maybe it's just too much of dmabuf memory.
