Subject: [PATCH 01/15] libata-pmp: update ata_eh_reset() for PMP
Date: Sun, 1 Jul 2007 19:54:13 +0900 [thread overview]
Message-ID: <1183287253915-git-send-email-htejun@gmail.com> (raw)
In-Reply-To: <1183287253677-git-send-email-htejun@gmail.com>
PMP always requires SRST to be enabled. Also, hardreset reports
classification code from the first device when PMP is attached, not
from the PMP. Update ata_eh_reset() such that followup softreset is
performed if the controller is PMP capable and the host link is being
reset.
