Subject: [PATCHSET] libata: reorganize configuration and implement revalidation
Date: Fri, 27 Jan 2006 00:39:11 +0900 [thread overview]
Message-ID: <1138289951261-git-send-email-htejun@gmail.com> (raw)
In-Reply-To:
Hello, again.
This patchset is against
upstream-2.6.17 (7db74a4780cf9cc6b2ea97582cdc8031d5f22ccd)
+ various fixes related to EH patchset [1]
+ three AHCI updates [2][3][4]
+ new reset mechanism patchset [5]
+ fixes regarding configuration patchset [6]
This patchset is consisted of 16 patches and can be categorized into
the following three parts.
#01-07 : prepare for ata_dev_identify() reorganization
#08-12 : reorganize ata_dev_identify() into ata_dev_read_id()
and ata_dev_configure()
#13-16 : implement and use revalidation using ata_dev_read_id()
and ata_dev_configure()
Also, please pay attention to the following. It's taken from #08's
description.
This function is probably the place to set transfer mode to PIO0
before IDENTIFY. However, reset -> identify -> init_dev_params
order should be kept for pre-ATA4 devices so we cannot set transfer
mode before IDENTIFY for them. How do we know if a device is
post-ATA4 before IDENTIFY?
How should we do this? Ignore pre-ATA4 devices?
Thanks.
