Subject: Soft-reset on a FIS-Based-Switching AHCI interface
Date: Mon, 12 Sep 2011 15:02:45 +0100 [thread overview]
Message-ID: <4E6E1105.6060103@plxtech.com> (raw)
The AHCI spec. seems to indicate that a soft-reset can only be performed
if FBS is disabled.
Looking at the LibATA and LibAHCI code at the moment, I can't see where
this is done. The soft-reset happens during error recovery when the port
re-enumerates devices.
Am I missing something or is this a _relatively_ less-well tested area
of the LibATA/AHCI operation?
