hi all !
Just installed openSUSE 10.3 Alpha3 with the new kernel 2.6.21-rc...
The problem is that all my IDE hard disks are displayed as "sda"...
Why is this?
I believe in 2.6.21-rcX the libata / pata support is still marked
experimental overall, but it is rapidly maturing and 2.6.22 may lose
that designation.
Someone else recently said that the next full OpenSUSE release would
not be until the fall. If so, the OpenSUSE team may be expecting to
use libata for PATA at that point and want to start getting it exposed
to users.
If you would like to still use the traditional drivers/ide subsection
it should be easy to recompile a reconfigured kernel from the sources.
i.e the source code should still be there.
Does it means that the kernel's SCSI module is now used for IDE Hard Disks ?
libata uses the scsi infrastructure, but less and less.
If so, then it's used for all media types: SCSI/IDE Hard Disks, CD
Burners, USB Flash Disks, etc... am I correct ?
I think so, but it is a compile time option for PATA drives.
Is there some link that explain this change in behavior ? (at user
level, not programmer level)
Don't know of one.
The biggest 2 changes I know of beyond naming convention are:
libata supports fewer partitions per drive (16?)
libata does not yet support HPA overriding. This is important because
if a user is using that feature in the old drivers/ide setup, then
libata will not be useable for them.
