        "content": "Hi Mattias,\n \n> A more extensive description of the purpose of the eventmode helper \n> library would be helpful.\n> \n> Is this supposed to be a generic framework for real-world \n> applications, or only something to simplify DPDK the implementation of \n> DPDK example programs and similar?\n \nThis is intended as a generic framework, but the initial targets would be limited to DPDK example applications.\n \nFor any application to use an event device for dynamic load balancing, it has to configure the event device and the adapters. Configuring the adapters would involve providing various parameters based on which the dynamic scheduling should happen. But requiring the application to do all this configuration would make the application complicated as well as the same code has to be repeated for a new application. Event mode helper tries to solve that.\n \nAll the complex configuration would be implemented by the helper library and the helper library would provide a default conf as well. \n \nThese patches facilitate event mode configuration in a easy to use manner. My idea is that, for a poll mode DPDK example to operate in event mode, a couple of helper functions and a lean worker thread should suffice. So even complex DPDK examples and real world applications will benefit from this helper library. We plan to propose a change to ipsec-secgw to operate in event mode once this proposal is merged.\n \nI'll update the cover-letter to add above details when sending v2.\n\nThanks,\nAnoob\n\n> -----Original Message-----\n> From: dev <dev-bounces@dpdk.org> On Behalf Of Mattias Rönnblom\n> Sent: Tuesday, June 11, 2019 4:14 PM\n> To: Jerin Jacob Kollanukkaran <jerinj@marvell.com>; Anoob Joseph\n> <anoobj@marvell.com>; Nikhil Rao <nikhil.rao@intel.com>; Erik Gabriel\n> Carrillo <erik.g.carrillo@intel.com>; Abhinandan Gujjar\n> <abhinandan.gujjar@intel.com>; Bruce Richardson\n> <bruce.richardson@intel.com>; Pablo de Lara\n> <pablo.de.lara.guarch@intel.com>\n> Cc: Narayana Prasad Raju Athreya <pathreya@marvell.com>; dev@dpdk.org;\n> Lukas Bartosik <lbartosik@marvell.com>; Pavan Nikhilesh Bhagavatula\n> <pbhagavatula@marvell.com>; Hemant Agrawal\n> <hemant.agrawal@nxp.com>; Nipun Gupta <nipun.gupta@nxp.com>; Harry\n> van Haaren <harry.van.haaren@intel.com>; Liang Ma\n> <liang.j.ma@intel.com>\n> Subject: [EXT] Re: [dpdk-dev] [PATCH 00/39] adding eventmode helper\n> library\n> \n> External Email\n> \n> ----------------------------------------------------------------------\n> On 2019-06-07 11:48, Jerin Jacob Kollanukkaran wrote:\n> >> -----Original Message-----\n> >> From: Anoob Joseph <anoobj@marvell.com>\n> >> Sent: Monday, June 3, 2019 11:02 PM\n> >> To: Jerin Jacob Kollanukkaran <jerinj@marvell.com>; Nikhil Rao\n> >> <nikhil.rao@intel.com>; Erik Gabriel Carrillo\n> >> <erik.g.carrillo@intel.com>; Abhinandan Gujjar\n> >> <abhinandan.gujjar@intel.com>; Bruce Richardson\n> >> <bruce.richardson@intel.com>; Pablo de Lara\n> >> <pablo.de.lara.guarch@intel.com>\n> >> Cc: Anoob Joseph <anoobj@marvell.com>; Narayana Prasad Raju Athreya\n> >> <pathreya@marvell.com>; dev@dpdk.org; Lukas Bartosik\n> >> <lbartosik@marvell.com>; Pavan Nikhilesh Bhagavatula\n> >> <pbhagavatula@marvell.com>; Hemant Agrawal\n> <hemant.agrawal@nxp.com>;\n> >> Nipun Gupta <nipun.gupta@nxp.com>; Harry van Haaren\n> >> <harry.van.haaren@intel.com>; Mattias Rönnblom\n> >> <mattias.ronnblom@ericsson.com>; Liang Ma <liang.j.ma@intel.com>\n> >> Subject: [PATCH 00/39] adding eventmode helper library\n> >>\n> >> This series adds support for eventmode helper library and l2fwd-event\n> >> application.\n> >>\n> >> First 13 patches creates a new l2fwd application (l2fwd-event).

I do agree that all the configuration exposed by eventdev & adapters are required for various requirements in the real world applications. But the requirement to understand & use all this configuration is making the applications complicated and causes significant effort from anyone who would want to get started with event mode. The idea of helper is to allow an easy framework for applications to get started with eventmode, and then use various options from C/L or config file (both planned) to override the configuration as required. DPDK has components like crypto-scheduler which abstracts lot of configuration and simplify usage from application's perspective. This effort is on similar lines.\n\nMy patchset is a followup to http://patches.dpdk.org/patch/37955 , wherein the approach of introducing a helper library for event mode was mooted. The initial patch proposed additions in one application, and that involved huge code additions just for doing the configuration.\n\nThe helper library will be experimental while we add event-mode support for other applications like l3fwd & ipsec-secgw. I expect the helper library to be complete over the course of those applications also using the helper library.\n\n> \n> What event devices have you tested with?\n\n[Anoob] Eventmode helper is tested with the following combinations, \n    1. event-octeontx event PMD & nicvf eth PMD\n    2. event-octeontx event PMD & eth-octeontx eth PMD",
