Subject: [PATCH 0 of 2] Add configuration options to selectively disable S3 and S4 (V3)
Date: Fri, 18 Nov 2011 10:35:03 +0000 [thread overview]
Message-ID: <patchbomb.1321612503@cosworth.uk.xensource.com> (raw)
This patch series adds the ability to selectively disable the S3 and S4 ACPI
power states for HVM guests.
Since there is a general move towards retiring the hvm_info_table structure,
the first patch moves the acpi_enabled flag out of the hvm_info_table and into
a xenstore key (platform/acpi).
The second patch then introduces the acpi_s3 and acpi_s4 configuration
parameters to the xl config file (default=1). These result in population of
new platform/acpi_s3 and platform/acpi_s4 xenstore keys. hvmloader then reads
these keys to determine whether or not to include SSDTs containing the
_S3 and _S4 packages respectively.
