From 33a58171e5995d9e649b414bfc77f2aab26e4c58 Mon Sep 17 00:00:00 2001 From: Ole Troan Date: Wed, 4 Sep 2019 09:12:29 +0200 Subject: api: autogenerate api trace print/endian In addition to the external vppapitrace tool, VPP itself supports dumping of API trace files. In two formats, "custom-dump" and "dump". "dump" gives a human friendly list, and "custom-dump" is meant to give a list of commands that can be fed to VAT. This patch only deals with "dump". Prior to this fix, auto-generation was only done for the basic types. This fix adds support for any type, including lists, and supports pretty-printing of enums, strings, IP addresses, MAC addresses and so on. Usage: api trace dump For example Change-Id: I4e485680e6dcfce7489299ae6cf31d835071ac40 ---------- trace 48 ----------- vl_api_sw_interface_set_flags_t: _vl_msg_id: 75 client_index: 0 context: 10 sw_if_index: 1 flags: IF_STATUS_API_FLAG_ADMIN_UP ---------- trace 49 ----------- vl_api_sw_interface_add_del_address_t: _vl_msg_id: 88 client_index: 0 context: 11 sw_if_index: 1 is_add: 1 del_all: 0 prefix: 172.16.1.1/24 ---------- trace 51 ----------- vl_api_cli_inband_t: _vl_msg_id: 819 client_index: 0 context: 13 cmd: packet-generator capture pg0 pcap /tmp/vpp-unittest-TestMAP-YhcmDX/pg0_out.pcap disable ---------- trace 58 ----------- vl_api_ip_neighbor_add_del_t: _vl_msg_id: 199 client_index: 0 context: 20 is_add: 1 neighbor: sw_if_index: 2 flags: IP_API_NEIGHBOR_FLAG_NONE mac_address: 0202.0000.ff02 ip_address: fd01:2::2 Signed-off-by: Ole Troan Change-Id: I5556d06008de2762e7c2d35a8b0963ae670b3db1 Type: fix Signed-off-by: Ole Troan Signed-off-by: Ole Troan Signed-off-by: Ole Troan Signed-off-by: Ole Troan Signed-off-by: Ole Troan Signed-off-by: Ole Troan Signed-off-by: Ole Troan Signed-off-by: Ole Troan --- src/vnet/ethernet/ethernet_format_fns.h | 27 +++++++++++++++++++++++++++ src/vnet/ethernet/ethernet_types.api | 2 +- 2 files changed, 28 insertions(+), 1 deletion(-) create mode 100644 src/vnet/ethernet/ethernet_format_fns.h (limited to 'src/vnet/ethernet') diff --git a/src/vnet/ethernet/ethernet_format_fns.h b/src/vnet/ethernet/ethernet_format_fns.h new file mode 100644 index 00000000000..17b5737913e --- /dev/null +++ b/src/vnet/ethernet/ethernet_format_fns.h @@ -0,0 +1,27 @@ +/* + * Copyright (c) 2019 Cisco and/or its affiliates. + * Licensed under the Apache License, Version 2.0 (the "License"); + * you may not use this file except in compliance with the License. + * You may obtain a copy of the License at: + * + * http://www.apache.org/licenses/LICENSE-2.0 + * + * Unless required by applicable law or agreed to in writing, software + * distributed under the License is distributed on an "AS IS" BASIS, + * WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or implied. + * See the License for the specific language governing permissions and + * limitations under the License. + */ + +#ifndef included_ethernet_format_fns_h +#define included_ethernet_format_fns_h + +static inline u8 * +format_vl_api_mac_address_t (u8 * s, va_list * args) +{ + u8 *a = va_arg (*args, u8 *); + return format (s, "%02x%02x.%02x%02x.%02x%02x", + a[0], a[1], a[2], a[3], a[4], a[5]); +} + +#endif diff --git a/src/vnet/ethernet/ethernet_types.api b/src/vnet/ethernet/ethernet_types.api index f945f20910f..1d6683ef398 100644 --- a/src/vnet/ethernet/ethernet_types.api +++ b/src/vnet/ethernet/ethernet_types.api @@ -14,4 +14,4 @@ * limitations under the License. */ -typedef u8 mac_address[6]; +manual_print typedef u8 mac_address[6]; -- cgit 1.2.3-korg
