From mboxrd@z Thu Jan 1 00:00:00 1970 From: Myron Stowe Subject: [PATCH v2 1/3] ipmi: Raise precedence of PNP based discovery mechanisms (ACPI, PCI) Date: Sat, 13 Mar 2010 11:13:42 -0700 Message-ID: <20100313181342.20614.72981.stgit@bob.kio> References: <20100313180121.20614.92547.stgit@bob.kio> Mime-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit Return-path: In-Reply-To: <20100313180121.20614.92547.stgit@bob.kio> List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , Errors-To: openipmi-developer-bounces@lists.sourceforge.net To: minyard@acm.org Cc: linux-acpi@vger.kernel.org, openipmi-developer@lists.sourceforge.net, linux-kernel@vger.kernel.org, lenb@kernel.org List-Id: linux-acpi@vger.kernel.org This raises the precedence of PNP discovery mechanisms, ACPI and PCI, above SMBIOS and SPMI as indicated by Appendix C1 of the IPMI specification. Reference: IPMI - Intelligent Platform Management Interface Specification v2.0, Document Revision 1.0, 05.05.2005 Markup Appendix C1 - Locating IPMI System Interfaces via SMBIOS Tables "Note that the settings that this structure reports may be over- ridden by `Plug-and-Play' reassignment by the OS. Therefore, this structure should be used only when the interface cannot be discovered via `Plug-and-Play' discovery mechanisms incorporated in interfaces such as PCI and ACPI."
