Hello=2C

Can anyon= e tell me that how I can run a DPDK application as a bare-metal (i.e. witho= ut Linux support). I've tried to run rump kernel TCP/IP stack by =3BAntti Kantee&= nbsp=3Bbut I'm unable to figure out that how I'll be u= sing it to run stand alone on x86 CPU. Currently I'm =3Brunning<= font size=3D"3"> =3Bthe rump kernel as a Linux application.

Thank you.

I've tried to run rump kernel TCP/IP stack by Antti Kantee but I'm unable to figure out that how I'll be using it to run stand alone on x86 CPU. Currently I'm running the rump kernel as a Linux application. Hi, As far as I've been able to gather, the open source version of DPDK does not include bare-metal support. However, I'm not very knowledgeable on DPDK, especially on code which I cannot read myself, so maybe someone else can answer that better. I do know something about rump kernels, though. One of main future use cases I see is indeed to have them run on bare metal and therefore allow to continue use essential kernel-only implemented features but still get rid of the prehistoric OS overhead layer. I have good reason to suspect that running rump kernels this would be easy, but as far as I know, no one has done the necessary work, at least not for x86. Unless the bare-metal version of DPDK provides a suitable portability layer, you'd be looking at implementing the rump kernel hypervisor interface for bare metal (or bare firmware ?-). In such a case, you might find using that using also the device layer from a rump kernel is the shortest path to initial success, with migration to DPDK only after reaching stability in that setup. But, that's getting quite off-topic for this list. Contact me off-list if you are serious about putting effort into the above. - antti From mboxrd@z Thu Jan 1 00:00:00 1970 Return-Path: Received: from acn-sweeper01.advantech.com.cn (unknown [58.211.163.100]) by dpdk.org (Postfix) with ESMTP id 4FC63232 for ; Wed, 19 Jun 2013 10:34:15 +0200 (CEST) Received: from acnht1.ACN.ADVANTECH.CORP (unverified [172.21.128.141]) by acn-sweeper01.advantech.com.cn (Clearswift SMTPRS 5.4.1) with ESMTP id ; Wed, 19 Jun 2013 16:34:25 +0800 From: =?utf-8?B?SmlhLlN1aSjotL7nnaIp?= To: Antti Kantee , Adeel Amin Date: Wed, 19 Jun 2013 16:34:23 +0800 Thread-Topic: [dpdk-dev] DPDK on bare-metal machine Thread-Index: Ac5sxv27wFju3s93Re2qKiBOANxWZgAAFdCA Message-ID: <581E2E1085FAEF45B48CF8A139824CF804E5D6D419@ACNMAIL1.ACN.ADVANTECH.CORP> References:

The only overhead left is the timer tick and that is being eliminated. Of course it is easy to write slow code and use system calls and defeat the purpose of DPDK. Has anyone experimented with making the DPDK threads marked as real-time to keep other processes away?
