From: Dan Williams Date: Fri, 18 Nov 2011 01:59:52 +0000 (-0800) Subject: [SCSI] libsas: use ->set_dmamode to notify lldds of NCQ parameters X-Git-Tag: v3.4-rc1~145^2~60 X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=b91bb296188118eea9fdc6093cfcf76bbe8589ba;p=pandora-kernel.git [SCSI] libsas: use ->set_dmamode to notify lldds of NCQ parameters sas_discover_sata() notifies lldds of sata devices twice. Once to allow the 'identify' to be sent, and a second time to allow aic94xx (the only libsas driver that cares about sata_dev.identify) to setup NCQ parameters before the device becomes known to the midlayer. Replace this double notification and intervening 'identify' with an explicit ->lldd_ata_set_dmamode notification. With this change all ata internal commands are issued by libata, so we no longer need sas_issue_ata_cmd(). The data from the identify command only needs to be cached in one location so ata_device.id replaces domain_device.sata_dev.identify.
