# Common code for recipes that modify the phosphor-mapper
# configuration.
#
# Typically it is not desired to monitor all dbus traffic
# on a system and as such, the phosphor-mapper has command
# line options to control what path namespaces and dbus
# interfaces it will keep track of.
#
# The Phosphor layer by default configures the mapper to
# watch xyz.openbmc_project interfaces and paths only.  This
# configuration file is intended to be inherited by
# native recipes in other layers that wish to add namespaces
# or interfaces to the mapper watchlist.

# Add path namespaces to be monitored:
# PHOSPHOR_MAPPER_NAMESPACE_append = " /foo/bar"

# Add interfaces to be monitored:
# PHOSPHOR_MAPPER_INTERFACE_append = " foo.bar"

# Blacklist paths from being monitored:
# PHOSPHOR_MAPPER_NAMESPACE_BLACKLIST_append = " /foo/bar/baz"

# Blacklist interfaces from being monitored:
# PHOSPHOR_MAPPER_INTERFACE_BLACKLIST_append = " foo.bar.baz"
