CONFIG_DCACHE_LINE_SIZE_DETECT
##############################

*Detect d-cache line size at runtime*

Type: ``bool``

Help
====

.. code-block:: none

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

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