From 2a1ca787b9ca0021bd5da73450caedc2ff41c76d Mon Sep 17 00:00:00 2001 From: Ole Troan Date: Thu, 19 Sep 2019 01:08:30 +0200 Subject: api: split api generated files Split generation of API message enum and the typedefs into separate files, so that the type file can be included from elsewhere. Generate a C file for VPP that contains the API registration, this was previously done via X macros by the C pre- processor. This allows deleting lots of skeleton/copy paste code for each feature. plugins/flowprobe plugins/map examples/sample-plugin vnet/ipip used as Guinea pigs. Generate a C Test file for VAT, that does the same for VAT plugins. Also add support for a per-message CLI option, that is currently limited to VAT help text. option vat_help = ""; Type: refactor Change-Id: I245e3104bb76f7e1fb69a59ab20cc7c8dfcdd460 Signed-off-by: Ole Troan --- src/plugins/flowprobe/flowprobe.c | 83 +++------------------------------------ 1 file changed, 6 insertions(+), 77 deletions(-) (limited to 'src/plugins/flowprobe/flowprobe.c') diff --git a/src/plugins/flowprobe/flowprobe.c b/src/plugins/flowprobe/flowprobe.c index 45de3a76be6..0b070219abd 100644 --- a/src/plugins/flowprobe/flowprobe.c +++ b/src/plugins/flowprobe/flowprobe.c @@ -32,34 +32,14 @@ #include /* define message IDs */ -#include - -/* define message structures */ -#define vl_typedefs -#include -#undef vl_typedefs - -/* define generated endian-swappers */ -#define vl_endianfun -#include -#undef vl_endianfun - -/* instantiate all the print functions we know about */ -#define vl_print(handle, ...) vlib_cli_output (handle, __VA_ARGS__) -#define vl_printfun -#include -#undef vl_printfun +#include +#include flowprobe_main_t flowprobe_main; static vlib_node_registration_t flowprobe_timer_node; uword flowprobe_walker_process (vlib_main_t * vm, vlib_node_runtime_t * rt, vlib_frame_t * f); -/* Get the API version number */ -#define vl_api_version(n,v) static u32 api_version=(v); -#include -#undef vl_api_version - #define REPLY_MSG_ID_BASE fm->msg_id_base #include @@ -88,6 +68,7 @@ VNET_FEATURE_INIT (flow_perpacket_l2, static) = /* *INDENT-ON* */ /* Macro to finish up custom dump fns */ +#define vl_print(handle, ...) vlib_cli_output (handle, __VA_ARGS__) #define FINISH \ vec_add1 (s, 0); \ vl_print (handle, (char *)s); \ @@ -756,11 +737,6 @@ vl_api_flowprobe_params_t_handler (vl_api_flowprobe_params_t * mp) REPLY_MACRO (VL_API_FLOWPROBE_PARAMS_REPLY); } -/* List of message types that this plugin understands */ -#define foreach_flowprobe_plugin_api_msg \ -_(FLOWPROBE_TX_INTERFACE_ADD_DEL, flowprobe_tx_interface_add_del) \ -_(FLOWPROBE_PARAMS, flowprobe_params) - /* *INDENT-OFF* */ VLIB_PLUGIN_REGISTER () = { .version = VPP_BUILD_VER, @@ -980,42 +956,6 @@ VLIB_CLI_COMMAND (flowprobe_show_stats_command, static) = { }; /* *INDENT-ON* */ -/** - * @brief Set up the API message handling tables - * @param vm vlib_main_t * vlib main data structure pointer - * @returns 0 to indicate all is well - */ -static clib_error_t * -flowprobe_plugin_api_hookup (vlib_main_t * vm) -{ - flowprobe_main_t *fm = &flowprobe_main; -#define _(N,n) \ - vl_msg_api_set_handlers((VL_API_##N + fm->msg_id_base), \ - #n, \ - vl_api_##n##_t_handler, \ - vl_noop_handler, \ - vl_api_##n##_t_endian, \ - vl_api_##n##_t_print, \ - sizeof(vl_api_##n##_t), 1); - foreach_flowprobe_plugin_api_msg; -#undef _ - - return 0; -} - -#define vl_msg_name_crc_list -#include -#undef vl_msg_name_crc_list - -static void -setup_message_id_table (flowprobe_main_t * fm, api_main_t * am) -{ -#define _(id,n,crc) \ - vl_msg_api_add_msg_name_crc (am, #n "_" #crc, id + fm->msg_id_base); - foreach_vl_msg_name_crc_flowprobe; -#undef _ -} - /* * Main-core process, sending an interrupt to the per worker input * process that spins the per worker timer wheel. @@ -1076,6 +1016,8 @@ VLIB_REGISTER_NODE (flowprobe_timer_node,static) = { }; /* *INDENT-ON* */ +#include + /** * @brief Set up the API message handling tables * @param vm vlib_main_t * vlib main data structure pointer @@ -1087,26 +1029,13 @@ flowprobe_init (vlib_main_t * vm) flowprobe_main_t *fm = &flowprobe_main; vlib_thread_main_t *tm = &vlib_thread_main; clib_error_t *error = 0; - u8 *name; u32 num_threads; int i; fm->vnet_main = vnet_get_main (); - /* Construct the API name */ - name = format (0, "flowprobe_%08x%c", api_version, 0); - /* Ask for a correctly-sized block of API message decode slots */ - fm->msg_id_base = vl_msg_api_get_msg_ids - ((char *) name, VL_MSG_FIRST_AVAILABLE); - - /* Hook up message handlers */ - error = flowprobe_plugin_api_hookup (vm); - - /* Add our API messages to the global name_crc hash table */ - setup_message_id_table (fm, &api_main); - - vec_free (name); + fm->msg_id_base = setup_message_id_table (); /* Set up time reference pair */ fm->vlib_time_0 = vlib_time_now (vm); -- cgit 1.2.3-korg
