sata_mv hotplug status?

sata_mv hotplug status?

[Tomasz Chmielewski]

I'm a little confused about sata_mv hotplug status.

According to http://linux-ata.org/driver-status.html#marvell, the driver 
has "full SATA control including hotplug".

A bit down on that same page, the matrix 
http://linux-ata.org/driver-status.html#matrix says sata_mv - device 
hotplug: no.

Which one is true? I guess the first says about drive hotplug, and the 
second says about (PCI) device hotplug?


Today, I tried to add a drive to that Marvell SATA controller:

01:00.0 SCSI storage controller: Marvell Technology Group Ltd. 
MV88SX6081 8-port SATA II PCI-X Controller (rev 09)


But it wasn't detected at all (no dmesg/kernel sign that the drive was 
connected) - I had to reboot the machine to get that drive  detected.

This would indicate that sata_mv doesn't support any sort of drive 
*plug? Or do I have to take some extra steps to get the drives detected?

I'm running 2.6.21 kernel.

Both are true.

The first discusses HARDWARE capabilities, the second lists SOFTWARE 
implementation features.
