Subject: [PATCHSET] libata: improve ata_bus_probe failure handling
Date: Sat, 1 Apr 2006 01:38:17 +0900 [thread overview]
Message-ID: <1143823097579-git-send-email-htejun@gmail.com> (raw)
In-Reply-To:
Hello, all.
This patchset is composed of 15 patches and aims to...
1. push more configuration responsibilities to higher level (from
ata_set_mode to ata_bus_probe)
2. implement speed down mechanism to be used by ata_bus_probe and
later by EH
3. improve ata_bus_probe such that it handles configuration failures
better (speed down, reset & retry)
The patches can be grouped as follows.
#01-05 : misc fixes/preprations around the affected code area
#06-08 : make ata_set_mode() fail instead of disabling devices directly
#09-13 : implement SATA SPD / transfer mode speed down mechanism
#14-15 : improve probing process such that it handles failures better
#05 is identical to the previously posted version[1]. #06-08 are
reimplementaion of [2].
Thanks.
