Subject: [PATCH v2 09/62] ACPICA: Make ACPI Power Management Timer (PM Timer) optional.
Date: Fri, 12 Jan 2018 11:28:17 +0000 [thread overview]
Message-ID: <20180112112910.16762-10-wei.liu2@citrix.com> (raw)
In-Reply-To: <20180112112910.16762-1-wei.liu2@citrix.com>
From: Bob Moore <robert.moore@intel.com>
PM Timer is now optional.
This support is already in Windows8 and "SHOULD" come out in ACPI 5.0A
(if all goes well).
The change doesn't affect Xen directly, because it does not rely
on the presence of the PM timer.
