Date: Tue, 11 Mar 2008 19:52:31 +0900 From: Tejun Heo <htejun@...il.com> To: Jeff Garzik <jeff@...zik.org>, IDE/ATA development list <linux-ide@...r.kernel.org>, linux-pci@...ey.karlin.mff.cuni.cz, Linux Kernel <linux-kernel@...r.kernel.org>, Greg KH <greg@...ah.com>, Jeff Garzik <jeff@...zik.org>, Alan Cox <alan@...rguk.ukuu.org.uk> Subject: [PATCH libata-dev#upstream-fixes] ahci: request all PCI BARs ahci is often implemented with accompanying SFF compatible interface and legacy IDE driver may attach to the legacy IO ports when the controller is already claimed by ahci and vice-versa. This patch makes ahci use pcim_iomap_regions_request_all() so that all IO regions are claimed on attach.
