# Configure OVS to use DPDK
|

#
|
|
# === Parameters
|
|
#
|
|
# [*memory_channels*]
|
|
# (required) The number of memory channels to use as an integer
|
|
#
|
|
# [*driver_type*]
|
|
# (Optional) The DPDK Driver type

|
# Defaults to 'vfio-pci'
|
|
#
|
|
# [*host_core_list*]
|
|
# (optional) The list of host cores to be used by the DPDK Poll Mode Driver
|
|
# The host_core_list is a string with format as <c1>[-c2][,c3[-c4],...] where c1, c2, etc are core indexes between 0 and 128
|
|
# For example, to configure 3 cores the value should be "0-2"
|
|
#
|
|
# [*package_ensure*]
|
|
# (Optional) State of the openvswitch package
|
|
# Defaults to 'present'.
|
|
#
|
|
# [*pmd_core_list*]
|
|
# (optional) The list of cores to be used by the OVS Agent
|
|
# The pmd_core_list is a string with format as <c1>[-c2][,c3[-c4],...] where c1, c2, etc are core indexes between 0 and 128

# For example, to configure 3 cores the value should be "0-2"
|
|
#
|
|
# [*socket_mem*]
|
|
# (Optional) Set the memory to be allocated on each socket
|
|
# The socket_mem is a string with comma separated memory list in MB in the order of socket numbers.
|
|
# For example, to allocate memory of 1GB for socket 1 and no allocation for socket 0, the value should be "0,1024"
|
|
# Defaults to undef.
|
|
#
|
|
# DEPRECATED PARAMETERS
|
|
#
|
|
# [*core_list*]
|
|
# (optional) Deprecated.
