Subject: RHEL5.0 PPC FEATURE 94948 RHBZ# 196336 Native SAS and SATA device
support
RHBZ#:
------
http://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=196336
Description:
------------
Update to ipr driver to support SAS attached SATA devices. This feature is
required by the eCLips systems to support native SAS and SATA drivers on
the planar.
RHEL Version Found:
-------------------
RHEL5.0 Feature
History:
--------
This patch was originally was posted 8/03, before the feature deadline:
http://post-office.corp.redhat.com/archives/rhkernel-list/2006-July/msg00338.html
A PM exception is being considered for this feature.
These ipr driver changes are dependent on the addition of new SAS
interfaces in the libata SATA code. In the 8/03 time frame, Jeff Garzik
was concerned about the API changing. This feature was postponed until
the API stabilized. Jeff's patch, which contained the necessary api's, was
moved to RHEL5 U1. Therefore an alternative patch was presented that
contained just the SAS api additions and minimized changes to the current
code base (the only change to the existing code is to export one
subroutine, ata_bus_probe):
http://post-office.corp.redhat.com/archives/rhkernel-list/2006-September/msg00136.html
This ipr patch was described in msg00136.html above. The identical code
is now being posted for formal review.
Upstream Status:
----------------
The final libata patches have been accepted by the libata maintainer:

d3ebaeb7b2641e69cbec44b61165fe7
Test Status:
------------
This patch was built and tested against:
http://people.redhat.com/dzickus/el5/1.2519.4.18.el5/
src/kernel-2.6.17-1.2519.4.18.el5.src.rpm
The patch builds & boot cleanly. This will be rebuilt if any changes
occur in the libata files while this is being considered for inclusion.
Test cases successfully executed described at:
http://bugzilla.redhat.com/bugzilla/attachment.cgi?id=135572
and further described in comment #39 of:
http://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=196336
Please review and ACK for RHEL5
Proposed Patch:
---------------
See attachments 1 and 2 to this email.
