From b2a8bbe67d73631c71492fd60b757fc50a87f182 Mon Sep 17 00:00:00 2001 From: Tejun Heo Date: Thu, 25 Jan 2007 19:40:05 +0900 Subject: libata: implement ATA_FLAG_IGN_SIMPLEX and use it in sata_uli Some uli controllers have stuck SIMPLEX bit which can't be cleared with ata_pci_clear_simplex(), but the controller is capable of doing DMAs on both channels simultaneously. Implement ATA_FLAG_IGN_SIMPLEX which makes libata ignore the simplex bit and use it in sata_uli.
