52.Fl l Ar length
53.Sh DESCRIPTION
54A number of supported system architectures allow the behaviour of the CPU
55cache to be programmed to behave differently depending on the region being
56written.
57.Pp
58The
59.Nm
60utility
61provides an interface to this facility, allowing CPU cache behavior to
62be altered for ranges of system physical memory.
63.Pp
64These ranges are typically power-of-2 aligned and sized, however the specific
65rules governing their layout vary between architectures. The
66.Nm
67utility does not attempt to enforce these rules, however the system will
68reject any attempt to set an illegal combination.
