.. title:: SPIN_VALIDATE

.. option:: CONFIG_SPIN_VALIDATE

*Enable spinlock validation*

Type: ``bool``

Help
====

There's a spinlock validation framework available when asserts are
enabled. It adds a relatively hefty overhead (about 3k or so) to
kernel code size, don't use on platforms known to be small.

Direct dependencies
===================

\ :option:`ASSERT <CONFIG_ASSERT>` && \ :option:`MP_NUM_CPUS <CONFIG_MP_NUM_CPUS>` <= 4

Default
