HP mv2120 from the front

Status of HP mv2120 support

The HP mv2120 is based on a Marvell Orion System on a Chip. Marvell has done a lot of work to get support for the Orion platform into the mainline kernel. However, some features of the Orion platform are not as well supported as in the original Marvell LSP (Linux Support Package) used by HP. Please take this into account before deciding whether you want to install Debian, especially if you have specific requirements (e.g. related to performance).

The table below shows how well different components of the HP mv2120 are supported by Debian:

Component Comment
Debian Debian installer works well
CPU Supported in mainline and Debian kernel since 2.6.25
mv2120 kernel Supported in the Debian kernel since 2.6.25 and in the mainline kernel since 2.6.27
SATA Supported in the kernel by the sata_mv module
Ethernet Supported in the kernel by the mv643xx module
USB Supported in the kernel since 2.6.25
RTC Supported in the kernel by the rtc-pcf8563 module
LEDs Supported in the Debian kernel as of 2.6.26 and Debian will use the LEDs to signal the status of the boot process.
Fan It seems the mv2120 has no temperature sensor or way to regulate the fan.
XOR engine Supported in the Debian kernel since 2.6.26 and in the mainline kernel since 2.6.27. Support is mainly helpful for RAID5 at the moment, so it's not quite useful on the mv2120
Crypto engine Basic support
