From 455b46a6be4bca145c047ed6957727c119285796 Mon Sep 17 00:00:00 2001 From: Alexandru Avadanii Date: Thu, 8 Nov 2018 19:06:46 +0100 Subject: Bring in FDIO (VPP+DPDK) scenario - cmp, gtw: bump RAM allocation to accomodate hugepages/VPP; for now we overcommit, gtw01 resources can probably be lowered; - submodule: add salt-formula-neutron so we can locally patch it; - repo: * FD.IO repos for VPP packages; * networking-vpp PPA for python-networking-vpp Neutron driver; - use vpp-router for L3, disable neutron-l3-agent; - baremetal_init: apply repo config before network (otherwise UCA repo is missing when trying to install DPDK on baremetal nodes); - arm64: iommu.passthrough=1 is required on ThunderX for VPP on newer kernels; Design quirks: - vpp service runs as 'neutron' user, which does not exist at the time VPP is installed and initially started, hence the need to restart it before starting the vpp-agent service; - gtw01 node has DPDK, yet to configure it via IDF we use the compute-specific OVS-targeted parameters like `compute_ovs_dpdk_socket_mem`, which is a bit misleading; - vpp-agent requires ml2_conf.ini on ALL compute AND network nodes to parse per-node physnet-to-real interface names; - vpp process is bound to core '1' (not parameterized via IDF); Change-Id: I659f7dbebcab7b154e7b1fb829cd7159b4372ec8 Signed-off-by: Alexandru Avadanii --- .../0002-network-Bring-in-basic-VPP-support.patch | 135 ++++++++++++++ .../0001-Bring-in-basic-VPP-support.patch | 204 +++++++++++++++++++++ .../0001-Support-rocky-version.patch | 71 ------- .../0002-Support-rocky-version.patch | 71 +++++++ 4 files changed, 410 insertions(+), 71 deletions(-) create mode 100644 mcp/patches/salt-formula-linux/0002-network-Bring-in-basic-VPP-support.patch create mode 100644 mcp/patches/salt-formula-neutron/0001-Bring-in-basic-VPP-support.patch delete mode 100644 mcp/patches/salt-formula-neutron/0001-Support-rocky-version.patch create mode 100644 mcp/patches/salt-formula-neutron/0002-Support-rocky-version.patch (limited to 'mcp/patches') diff --git a/mcp/patches/salt-formula-linux/0002-network-Bring-in-basic-VPP-support.patch b/mcp/patches/salt-formula-linux/0002-network-Bring-in-basic-VPP-support.patch new file mode 100644 index 000000000..756c575b4 --- /dev/null +++ b/mcp/patches/salt-formula-linux/0002-network-Bring-in-basic-VPP-support.patch @@ -0,0 +1,135 @@ +:::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::: +: Copyright (c) 2018 Mirantis Inc., Enea AB and others. +: +: All rights reserved.
