CONFIG_ICACHE_LINE_SIZE_DETECT
##############################

*Detect i-cache line size at runtime*

Type: ``bool``

Help
====

.. code-block:: none

    This option enables querying some architecture-specific hardware for
    finding the i-cache line size at the expense of taking more memory and
    code and a slightly increased boot time.

    If the CPU's i-cache line size is known in advance, disable this option and
    manually enter the value for ICACHE_LINE_SIZE or set it in the DT
    using the 'i-cache-line-size' property.
