Re: [vpp-dev] duplicate user id allocation in ACL plugin

Hi Andrew, We dont want to have any extra config/APIs to drive this registration and hence, we did not go via that approach. To work around this, I have started a timer of 1 sec in my custom plugin init function. After 1 sec, I am registering with the ACL service, and this solved my issue for

Re: [vpp-dev] duplicate user id allocation in ACL plugin

Hi Andrew, One difference I see between our plugin vs Gbp plugin is: In Gbp plugin, register_module is getting called as part of an API handler, which is usually after the system comes to a stable state. Whereas in our case, we are calling register_module as part of our plugin init function,

Hi Andrew, I was trying to get this info on one other thread and did not realize your message in this thread. If I put this in feature_enable function, I need to trigger this function via API (or) CLI, which we want to avoid. We want to get the registration as part of our plugin

Re: [vpp-dev] About the order of  VLIB_INIT_FUNCTION called between different plugins

Donno, my previous reply didnt come to the group, hence resending. Hi Dave, In fact, I tried using vlib_get_plugin_symbol for acl_init() function. But, since its a static function, I am returned with NULL. -- Thanks & Regards, Murthy -=-=-=-=-=-=-=-=-=-=-=- Links: You receive all messages sent

Re: [vpp-dev] About the order of  VLIB_INIT_FUNCTION called between different plugins

Hi Neale, Thanks for the information. I have been trying to use this approach but not successful. I am trying to call acl plugin's init function from my custom plugin. But, looks like, it is not able to get the acl_init symbol, and hence the custom plugin loading itself is failing. Following

Re: [vpp-dev] About the order of  VLIB_INIT_FUNCTION called between different plugins

Sorry. I should have asked how to get the init functions in a specific order. Coz, ACL plugin init is getting called after my customplugin init and hence the registration from my plugin is getting wiped off. -- Thanks & Regards, Murthy -=-=-=-=-=-=-=-=-=-=-=- Links: You receive all messages sent

Re: [vpp-dev] About the order of  VLIB_INIT_FUNCTION called between different plugins

Hi Damjan, In the example you mentioned where bar_init() is trying to find if foo_plugin is really loaded or not. If foo_plugin is found to be not loaded, a warning is printed and returning a 0. But this does not gaurantee that bar_init() is called once again after a while, isnt it ? So, in

Hi Ben, I dont see any constructs called runs_before or runs_after within VLIB_INIT_FUNCTION macro. I am getting compilation error when I try these changes. I could not find any VLIB_INITS in 1810 (or) 1904 versions of the code. Here is the code I tried. VLIB_INIT_FUNCTION

Re: [vpp-dev] duplicate user id allocation in ACL plugin

Hi Andrew, I got what the issue is, but not sure how to get around this problem. My plugin is first subscribing for ACL service by calling register_user_module. Also, I could see that it is getting added into acl_users. But, after this, acl_init() is getting called, due to which, the acl_users

[vpp-dev] cache hits/misses counters per plugin/graph node

Hi, Is there any way we can get the cache hits/misses ( I-Cache and D-Cache ) for a specific plugin/graph node ? Linux perf tools give these at the process level, but may not be much help if we want to really bench mark a specific graph node. Any info in this regard ? -- Thanks & Regards,

Hi, Is there any built-in framework/CLI within VPP, that keeps track of cache hits/misses for D-cache and I-Cache at graph node or plugin level ? (or) we need to use general linux perf tools for getting this data ? Even if we do this using perf tools, we may get this at the whole process

Hi Neale, Thank you very much for the reply. The main problem that we are facing is: The plugin that we are planning to develop need to configure the classification rules dynamically ( ACLs ). Hence, we can not use VPP-API approach to configure the ACLs first. We need to add the ACLs based on
