Subject: [PATCH v8 0/2] x86/devicetree: Enable multiprocessing
Date: Thu, 22 Mar 2018 14:35:19 -0700	[thread overview]
Message-ID: <cover.1521753738.git.ivan.gorinov@intel.com> (raw)

Current x86 implementation of Device Tree does not support multiprocessing,
and the bindings documentation describes the "reg" property of "cpu" nodes
as "CPU number" instead of hardware-assigned local APIC ID.

v8:
 * Fixed build error with CONFIG_X86_LOCAL_APIC=n reported by kbuild.

v7:
 * Change log update.

v6:
 * Calling of_property_read_u32() to get Local APIC ID from "reg".

 * DT documentation changes: corrected CPU node example and changed
   the "reg" property description.

v5:
 * Using the "reg" property to specify Local APIC ID.
