.. title:: ICACHE_LINE_SIZE_DETECT

.. option:: CONFIG_ICACHE_LINE_SIZE_DETECT

*Detect i-cache line size at runtime*

Type: ``bool``

Help
====

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.
