GRPC_C DEVICE SIMULATOR

This is a executable(voltha_bal_driver), which will received asfvolt16 adapter grpc-c messages and call respective device stub. It will send recevied responses/asynchronous indications from Device stub to Adapter.

GETTING STARTED

prerequisites to install grpc

  • sudo apt-get install build-essential libxml2-dev libgeos++-dev libpq-dev libbz2-dev libtool automake openssl libssl-dev golang-goprotobuf-dev

INSTALLATION

Open Network Linux This guide assumes that Open Network Linux (ONL) is available at ${HOME}/OpenNetworkLinux. All the below steps need to be executed in the ONL build docker context. Refer to ONL build instructions (https://wiki.opencord.org/download/attachments/2556712/ONL_Build_Environment_Installation_Guide.pdf?api=v2).

- Download ONL source code with Kernel 3.7.10.

    > git clone https://github.com/Lewis-Kang/OpenNetworkLinux.git -b kernel_3.7.10

- Start ONL build docker workspace

    > cd OpenNetworkLinux
    > docker/tools/onlbuilder -8   # enter the docker workspace

Clone asfvolt16-driver - The guide assumes that the asfvolt16-driver gerrit repo is cloned under the ONL toplevel directory: - git clone ssh://user@gerrit.opencord.org:29418/asfvolt16-driver ${HOME}/OpenNetworkLinux/asfvolt16-driver

steps to install grpc

  • Download as zip "grpc", "grpc-c", "protobuf" and "protobuf-c" from "https://github.com/opennetworkinglab/asfvolt16-driver/tree/master/third_party"
  • extract grpc at ${HOME}/OpenNetworkLinux/grpc
  • extract grpc-c at ${HOME}/OpenNetworkLinux/grpc-c
  • extract protobuf at ${HOME}/OpenNetworkLinux/grpc/thirdparty/protobuf
  • extract protobuf-c folder at ${HOME}/OpenNetworkLinux/grpc-c/third_party/protobuf-c
  • cd ${HOME}/OpenNetworkLinux/grpc/thirdparty/protobuf
    • ./autogen.sh
    • ./configure
    • make
    • sudo make install
  • cd ${HOME}/OpenNetworkLinux/grpc
    • export LD_LIBRARY_PATH=/usr/local/lib
    • make
    • sudo make install

steps to install grpc-c

  • cd ${HOME}/OpenNetworkLinux/grpc-c/third_party/protobuf-c
    • ./autogen.sh
    • ./configure
    • export PKG_CONFIG_PATH=/usr/local/lib/pkgconfig/protobuf
    • make
    • sudo make install

Apply grpc-c patch

  • cd ${HOME}/OpenNetworkLinux/grpc-c/ Patch 1: Apply patch in following link for grpc-c/lib - "https://github.com/Juniper/grpc-c/commit/353b40cd920cd749ed6cf71f8df17f1d5cf2c89d" Note: (This patch is having very few changes in two files(grpc-c/lib/client.c, grpc-c/lib/service.c. Download these two files from above link and replace at grpc-c/lib or merge these changes manually.)
    Patch 2: Apply patch in service.c.patch and client.c.patch

    • cd ${HOME}/OpenNetworkLinux

    • cp asfvolt16-driver/device_simulator/Makefile.am grpc-c/examples/

    • cp asfvolt16-driver/device_simulator/voltha_bal_driver.c grpc-c/examples/

    • cp asfvolt16-driver/device_simulator/bal_stub.c grpc-c/examples/

    • cp asfvolt16-driver/device_simulator/bal_stub.h grpc-c/examples/

      • Note: Update voltha adaptor IP in bal_stub.c (Is this required? Not clear which variable needs to be updated).

    • cd ${HOME}/OpenNetworkLinux/grpc-c

    • autoreconf --install

    • mkdir build && cd build

    • ../configure

    • make

    • sudo make install

To obtain proto files - Have a repo sync of opencord voltha code base: - git clone https://github.com/opencord/voltha.git ${HOME}/voltha - cd ${HOME}/OpenNetworkLinux/grpc-c/ - cp ${HOME}/voltha/voltha/adapters/asfvolt16_olt/protos/* examples/

To autogenerate code from proto files: - cd ${HOME}/OpenNetworkLinux/grpc-c/build/examples - make autogen

Build voltha_bal_driver: - cd ${HOME}/OpenNetworkLinux/grpc-c/build/examples - Note: Remove "-O2" from Makefile - Note: Set EDGECORE and BRCM_PATH in Makefile

       EDGECORE = ${HOME}/OpenNetworkLinux/asfvolt16-driver/src/
       BRCM_PATH = ${HOME}/OpenNetworkLinux/bal_src_release/bal_release

 - make clean_all;make

The ultimate executable voltha_bal_driver can be found under ~/grpc-c/build/examples/.libs/

USAGE: ./voltha_bal_driver "serverIP:port1" -C "serverIP:port2" -A "serverIP:port3" ./bal_core_dist -C "serverIP:port2" -A "serverIP:port3"

NOTE: bal_core_dist is a broadcom executable
