#
# Overlay definitions to build SOF firmware for use
# with SOF driver in Linux kernel

# As a general rule, update of SOF firmware shall never
# break existing systems by depending on Linux kernel patches
# that have been upstreamed after commercial availability
# of a product.

# SOF Linux driver does not require FW to retain its
# state, so context save can be disabled

# Logging options

# Set default runtime log level to INFO (3).
# Note: This setting only has effect when CONFIG_LOG_RUNTIME_FILTERING is enabled.
# By default, the runtime level equals the compile-time level, but it is explicitly
# set here to INFO to ensure expected behavior if platform configurations set a
# lower default level (e.g., ERROR).
