+.Sh SYNOPSIS
+.Nm
+.Ar channel_number
+.Ar num_loops
+.Sh DESCRIPTION
+.Nm
+allows one to issue some number of test operations to the
+.Xr ioat 4
+driver on a specific hardware channel.
+.Pp
+Each loop will allocate two chunks of memory, write data patterns to them,
+submit a DMA request to copy one buffer to the other, and compare the contents
+in the callback.
+If the contents are not as expected, an error is reported.
+.Sh FILES
+.Pa /dev/ioat_test
+.Pp
+The interface between
+.Nm
+and
+.Xr ioat 4 .
+.Nm
+exposes it with
+.Cd hw.ioat.enable_ioat_test=1 .
+.Sh SEE ALSO
+.Xr ioat 4
+.Sh HISTORY
+The
+.Xr ioat 4
+driver first appeared in
+.Fx 11.0 .
