Hi !
I am quite new with HW RAID drivers, and I want to support a PCIe /
2xSATA board based on ASM1062R chip.
It is seen as AHCI so Linux can see the disks and that's something.
But now, I want to modify the configuration to use RAID-0 or RAID-1,
and there is nothing right now, according to my search ?
This chip understands vendor commands using a CMD/ACK message with MMIO offsets.
I now have several questions (maybe irrelevant :)) :
- Where should this driver be ? md ? scsi ?
- These vendor commands are under NDA right now, so I think it should
not be written in the driver obviously, but I am pretty sure there is
a nice way to do it ;-) ?
Basically, this is a 32 bits word with CMD and some args, and an ACK
with some args, which should be parsed.
Should it be in a specific proprietary user space application (yuck !) ?
Thanks for your help, this is a very early stage exploration, so feel
free to give any idea :D.
