HI, I have a question about sel4bench IPC. Thanks for the reply.
1. Making seL4_IPCBuffer and mapping into the thread is necessary? I think that sending short messages don't need seL4_IPCBuffer, is it right?
2. This is seL4_Call annotation in benchmark_param. /* Call fastpath between client and server in the different address space */
But I can't understand how to measure seL4_Call function performance.
[Client thread] [Server thread] seL4_Call seL4_ReplyRecv(I'm not sure)
1) client send message. 2) server receive message. 3) server send message. 4) client receive message.
seL4_Call performance in sel4bench excluding overhead , is it right? = 1) + 2) + 3) + 4) - 3) - 4)
3. This is seL4_Send annotation in benchmark_param. /* Send slowpath (no fastpath for send) same prio client-server, different address space */ But client_prio(seL4_MaxPrio - 1) and server_prio(seL4_MaxPrio - 2) is different.
