From db62fda318a6b9082ee9d230be8b45e56b6545c0 Mon Sep 17 00:00:00 2001 From: Sudeep Holla Date: Wed, 17 Feb 2016 11:54:19 +0000 Subject: ACPI / processor : add support for ACPI0010 processor container ACPI 6.0 adds support for optional processor container device which may contain child objects that are either processor devices or other processor containers. This allows representing hierarchical processor topologies. It is declared using the _HID of ACPI0010. It is an abstract container used to represent CPU topology and should not be used to hotplug purposes. If no matching handler is found for a device in acpi_scan_attach_handler, acpi_bus_attach does a default enumeration for those devices with valid HID in the acpi namespace. This patch adds a scan handler for these ACPI processor containers to avoid default that enumeration and ensures the platform devices are not created for them.

It's used in system suspend/resume path as a syscore operation. It makes more sense to move it to acpi/sleep.c where all the S-state transition (a.k.a. Linux system suspend/hiberate) related code are present. Also make it depend on CONFIG_ACPI_SYSTEM_POWER_STATES_SUPPORT so that it's not compiled on architecture like ARM64 where S-states are not yet defined in ACPI.
