.Sh HISTORY
The
.Nm
driver first appeared in
.Nx 6.0 .
NCQ support was added, and ATAPI support enabled, in
.Nx
on October 7, 2017 .
.Sh AUTHORS
The
.Nm
driver was written by
.An KIYOHARA Takashi Aq Mt kiyohara@kk.iij4u.or.jp .
NCQ support was added by
.An Jaromir Dolecek Aq Mt jdolecek@NetBSD.org .
.Sh BUGS
.Bl -tag -width Ds -compact
.It NCQ is only enabled on Gen IIe controllers .
.It Device hot swapping is not yet supported .
.It Marvell's Software RAID is not supported by the
.Xr ataraid 4
driver.
.Xr raid 4
can be used instead.
.El
.Pp
This controller hardware is very old and pretty peculiar, with
poor ATAPI support.
It's very unlikely that the driver will receive any further changes,
particularily not for the Gen I and Gen II controllers.
Use an
.Xr ahcisata 4
compatible controller instead.
