I have a question about developing Intel QAT Application.
Can you please help us on this issue?
I want to develop NGINX Application that accelerate SSL processing using QAT Engine and OpenSSL 1.1.0 pre5 by EVENT_DRIVEN.
It is listed in a document as follows:
* It must be sent if required after engine creation but before engine initialization. It should not be sent after engine initialization.
I think that "Engine initialization" is Engine_init.
Because qat_engine_init which is called by Engine_init finished all in the following logics, after I can not acquire FD using GET_POLLIG_FD.
/* Work around for fork case, finish engine in parent process */
if(initiator_pid == 0) {
qat_engine_finish(e);
qat_inited = 0;
keep_polling = 1;
}
In the qat_engine_init source comment, I think that this considers master/worker process like the nginx.
Because qat_engine_init is called from "CRYPTO_THREAD_run_once(&engine_lock_init, do_engine_lock_init);", it is called only once.
In other words it is never called in worker because it is initialized in master.
How should I initialize it?
