[PATCH] libata: rewrite SCSI host scheme to be one per ATA host
From: Jeff Garzik
Date: Wed Apr 22 2009 - 05:09:58 EST
Currently, libata creates a Scsi_Host per port. This was originally
done to leverage SCSI's infrastructure to arbitrate among master/slave
devices, but is not needed for most modern SATA controllers. And I
_think_ it is not needed for master/slave if done properly, either.
The patch below converts libata such that there is now a 1:1
correspondence between struct Scsi_Host and struct ata_host. ATA ports
are represented as SCSI layer 'channels', which is more natural.
This patch is an experiment, and not meant for upstream anytime soon.
I just wanted to see what kind of effort would be required to get it
to work.
I was able to successfully boot the following patch on
AHCI/x86-64/Fedora.
It may work with other controllers -- TRY AT YOUR OWN RISK. It will
probably fail for master/slave configurations, and SAS & PMP also
need looking at. It yielded this lsscsi output on my AHCI box:
[0:0:0:0] disk ATA ST3500320AS SD15 /dev/sda
