libata & SATA

[matt_heys]

I'm having issues getting my SATA drives to work, I have enabled libata and ticked all the SATA controllers but I still can't pick up my drives.

I'm building a Kernel (2.6.28.2) + Busybox initrd system and need to be able to see the disks, currently fdisk -l comes back blank.

Does anyone know the minimal options to get libata working for both Parallel and Sata drives?

EDIT: I should point out I want to use a static Kernel with no modules, don't know if that makes a difference.

Did you include SATA support when you build your Kernel?

The SATA driver falls under SCSI code, so you would need the SCSI subsystem support as well.

lsmod | grep ata
ata_generic            23812  0 
libata                149320  2 ahci,ata_generic
scsi_mod              152664  5 st,sr_mod,sg,sd_mod,libata

Yes, you are right. But (2TopicStarter) don't forget to include drivers for you SATA controller.

As I put in my first post I have put libata and all the available SATA controllers in to the kernel.

I have enabled SCSI support and SCSI Disk support but only those two, if it would help I could post my .config but it's at home and despite the snow I'm not.

What is ata_generic? do you know what kernel option that would fall under or is it done automatically?

Since I've built a static kernel I don't think lsmod will work but I will build it in busybox and give it a try to see if it's all there.

Thanks for taking a look.

Dunno if it will help, but...

Thanks for the Kernel configs, it wasn't that though but cheers for the help anyway.

I dug through the dmesg output (after I added dmesg to busybox) found some errors and googled them, turns out you need some processor functions enabled as well.

I enabled quite a few and it worked, things like SMP and Multicore Scheduler, Hyperthreading and ACPI.

Now I'm just disabling them one by one to see which ones I actually need, I've rebuilt the kernel about 30 times today.

When I've pinpointed it I will post what I needed in the end along with the errors from dmesg, so anyone finding this by google won't have to rebuild their Kernel so many times.
