From mboxrd@z Thu Jan 1 00:00:00 1970 From: Prarit Bhargava Subject: RFC: Output ACPI info via sysfs Date: Thu, 11 May 2006 10:57:34 -0400 Message-ID: <446350DE.9010900@redhat.com> Mime-Version: 1.0 Content-Type: text/plain; charset=ISO-8859-1; format=flowed Content-Transfer-Encoding: 7bit Return-path: Received: from mx1.redhat.com ([66.187.233.31]:14061 "EHLO mx1.redhat.com") by vger.kernel.org with ESMTP id S1751818AbWEKO5r (ORCPT ); Thu, 11 May 2006 10:57:47 -0400 Sender: linux-acpi-owner@vger.kernel.org List-Id: linux-acpi@vger.kernel.org To: linux-acpi@vger.kernel.org Cc: "Brown, Len" Currently, after booting a system there is no way to tell what hardware is currently in the system. The current output from sysfs only indicates what knowledge the kernel has of the system (ie, is limited by NR_CPUS, etc.). However, during ACPI initialization a lot of data is output to the console about the precise number of CPUs, lapics, etc. Having this information is useful to anyone (or any application) interested in querying the real system information. Any thoughts, concerns? (Code not yet generated -- just looking for an okay on the RFC) P.
