Testing: Verified kernel defaults to ACPI on Mustang
|
|
|
|
From: Jonathan Toppins <jtoppins@redhat.com>
|
|
|
|
This patch forces ACPI boot tables to be preferred over DTS.
|
|
|
|
Currently for ACPI to be used a user either has to set acpi=on on the
|
|
kernel command line or make sure any device tree passed to the kernel
|
|
is empty. If the dtb passed to the kernel is non-empty then device-tree
|
|
will be chosen as the boot method of choice.
|
|
|
|
RHEL does not wish to support this boot method so change table boot
|
|
preferences to use ACPI. In the event ACPI table checks fail the kernel
|
|
will fallback to using DTS to boot.
