# NAME

`mvsata` —
Marvell Hercules-I and Hercules-II SATA controllers driver

# SYNOPSIS

`mvsata* at pci? dev ? function ?`

# DESCRIPTION

The `mvsata` driver supports the Marvell Hercules-I and Hercules-II family of SATA controllers, interfacing the hardware with the ata(4) and atapi(4) subsystems.

Gen I
  - SATA 1.5Gbps; no support for NCQ, PMP, ATAPI
  - Supported controllers:
    - Marvell 88SX50xx Hercules-I
Gen II
  - SATA 3Gbps, NCQ, and PMP support; no ATAPI support
  - Supported controllers:
    - Adaptec RAID 1420SA
    - Marvell 88SX60xx Hercules-II
Gen IIe
  - SATA 3Gbps, NCQ, PMP, ATAPI support
  - Supported controllers:
    - Adaptec RAID 1430SA

# HISTORY

The `mvsata` driver first appeared in NetBSD 6.0. NCQ support was added, and ATAPI support enabled, in NetBSD on October 7, 2017 .

# AUTHORS

The `mvsata` driver was written by KIYOHARA Takashi <kiyohara@kk.iij4u.or.jp>. NCQ support was added by
Jaromir Dolecek <jdolecek@NetBSD.org>.

# BUGS

NCQ is only enabled on Gen IIe controllers.
Device hot swapping is not yet supported.
Marvell's Software RAID is not supported by the
  ataraid(4) driver. raid(4) can be used instead.

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 ahcisata(4) compatible controller instead.
