* PMD for Cisco VIC Ethernet NIC - Request for guidelines for submission @ 2014-05-28 6:05 Sujith Sankar (ssujith) [not found] ` <CFAB7A96.19CB4%ssujith-FYB4Gu1CFyUAvxtiuMwx3w@public.gmane.org> 0 siblings, 1 reply; 7+ messages in thread From: Sujith Sankar (ssujith) @ 2014-05-28 6:05 UTC (permalink / raw) To: dev-VfR2kkLFssw Hi all, We have been working on development of poll-mode driver for Cisco VIC Ethernet NIC and integration of it with DPDK. We would like to submit this poll-mode driver (ENIC PMD) to the DPDK community so that it could be part of the DPDK tree. Could someone please provide the guidelines and steps to do this? As of now, ENIC PMD is being tested with DPDK 1.6.0r2. Is it alright to submit a patch for DPDK 1.6.0r2? One aspect of ENIC PMD is that it works with VFIO-PCI and not UIO. Hope this is acceptable. The following thread in dpdk-dev influenced this decision. http://dpdk.org/ml/archives/dev/2013-July/000373.html ENIC PMD uses one interrupt per interface and it is used by the NIC for signalling the driver in case of any error. Since this does not come in the fast path, it should be acceptable, isn¹t it? Please give your suggestions and comments. Thanks, -Sujith ^ permalink raw reply [flat|nested] 7+ messages in thread
