Subject: PATA+SATA controllers and libata (was Re: IDE connector on Promise 20376 SATA controller)
Date: Fri, 24 Sep 2004 19:24:24 -0400 [thread overview]
Message-ID: <4154ACA8.80401@pobox.com> (raw)
In-Reply-To: <58cb370e04092415506cacdf86@mail.gmail.com>
The problems to solve, in order to support PATA and SATA on the same
controller:
1) struct ata_probe_ent describes a single host controller. It has a
single struct ata_port_operations pointer. To support PATA and SATA on
the same controller, multiple ata_port_operations pointers must be
supported.
2) struct ata_host_set uses a single struct ata_port_operations for the
entire host controller.
Fix those two things, and support for PATA+SATA controllers is possible.
