From mboxrd@z Thu Jan 1 00:00:00 1970 From: Grant Grundler Subject: [PATCH] enable ACPI/NUMA for HP ZX1 config Date: Wed, 25 Jan 2006 21:59:17 -0800 Message-ID: <20060126055917.GA12615@esmail.cup.hp.com> Mime-Version: 1.0 Content-Type: text/plain; charset=us-ascii Return-path: Received: from palrel10.hp.com ([156.153.255.245]:6575 "EHLO palrel10.hp.com") by vger.kernel.org with ESMTP id S1750798AbWAZF7G (ORCPT ); Thu, 26 Jan 2006 00:59:06 -0500 Content-Disposition: inline Sender: linux-acpi-owner@vger.kernel.org List-Id: linux-acpi@vger.kernel.org To: linux-ia64@vger.kernel.org Cc: linux-acpi@vger.kernel.org Tony, Bjorn/Alex cleaned up IA64_HP_ZX1 to also support SX1000 as well. I suspect NUMA was introduced later and HP forgot to update the ZX1/SX1000 config to also support NUMA. ACPI support just seems to have been overlooked since it's required for HP platforms. How would you prefer to handle ACPI_NUMA? Instead of adding more machines to change the default, I suggest the default be "Y" with no coniditions (as proposed below). Given the "depends NUMA", it means the user already said Y to NUMA, this only applies if ia64 or x86_64, and I don't expect any performance impact in the ACPI code path. thanks, grant Signed-off-by: Grant Grundler --- a/arch/ia64/Kconfig 19 Dec 2005 12:42:13 -0000 +++ b/arch/ia64/Kconfig 25 Jan 2006 21:08:04 -0000 @@ -90,12 +90,14 @@ config IA64_DIG config IA64_HP_ZX1 bool "HP-zx1/sx1000" + select ACPI help Build a kernel that runs on HP zx1 and sx1000 systems.
