From mboxrd@z Thu Jan 1 00:00:00 1970 From: Bjorn Helgaas Subject: [PATCH 1/3] ACPI: use LNXCPU, not ACPI_CPU, for Linux-specific processor _HID Date: Mon, 27 Apr 2009 16:33:36 -0600 Message-ID: <20090427223336.16549.82546.stgit@bob.kio> References: <20090427223244.16549.99553.stgit@bob.kio> Mime-Version: 1.0 Content-Type: text/plain; charset="utf-8" Content-Transfer-Encoding: 7bit Return-path: Received: from g4t0015.houston.hp.com ([15.201.24.18]:24055 "EHLO g4t0015.houston.hp.com" rhost-flags-OK-OK-OK-OK) by vger.kernel.org with ESMTP id S1757759AbZD0Wdg (ORCPT ); Mon, 27 Apr 2009 18:33:36 -0400 In-Reply-To: <20090427223244.16549.99553.stgit@bob.kio> Sender: linux-acpi-owner@vger.kernel.org List-Id: linux-acpi@vger.kernel.org To: Len Brown Cc: linux-acpi@vger.kernel.org ACPI_PROCESSOR_OBJECT_HID is a synthetic _HID that Linux generates for "Processor" definitions. Unlike "Device" definitions, "Processor" definitions do not have a _HID in the namespace, so we generate a fake _HID. By convention, all these fake _HIDs begin with "LNX". This does change the user-visible _HID for "Processor" objects -- previously, we used "ACPI_CPU" and this changes that to "LNXCPU", which starts with "LNX" as do all the other made-up _HIDs. This change is visible in processor filenames and "hid" files under /sys/devices/LNXSYSTM:00/.
