From mboxrd@z Thu Jan 1 00:00:00 1970 Return-Path: Received: from mx1.redhat.com ([209.132.183.28]:11654 "EHLO mx1.redhat.com" rhost-flags-OK-OK-OK-OK) by vger.kernel.org with ESMTP id S1750905AbaCGHrf (ORCPT ); Fri, 7 Mar 2014 02:47:35 -0500 Date: Fri, 7 Mar 2014 08:49:32 +0100 From: Alexander Gordeev To: Dan Williams Cc: "linux-kernel@vger.kernel.org" , Vinod Koul , "dmaengine@vger.kernel.org" , linux-pci@vger.kernel.org Subject: [PATCH v2] ioat: Use pci_enable_msix_exact() instead of pci_enable_msix() Message-ID: <20140307074932.GC2670@dhcp-26-207.brq.redhat.com> References: <2ba22558b5db90740d5833c35570c3e7cc1e359e.1394128952.git.agordeev@redhat.com> <20140306214356.GA16376@dhcp-26-207.brq.redhat.com> MIME-Version: 1.0 Content-Type: text/plain; charset=us-ascii In-Reply-To: Sender: linux-pci-owner@vger.kernel.org List-ID: As result of deprecation of MSI-X/MSI enablement functions pci_enable_msix() and pci_enable_msi_block() all drivers using these two interfaces need to be updated to use the new pci_enable_msi_range() or pci_enable_msi_exact() and pci_enable_msix_range() or pci_enable_msix_exact() interfaces. Function pci_enable_msix() returns a tri-state value while pci_enable_msi_exact() is a canonical zero/-errno variant. The former is being phased out in favor of the latter. In case of 'ioat' there (should be) no difference.
