.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.
