Subject: [PATCH] cpufreq/intel_pstate: Change to disallow module build
Date: Wed, 13 Feb 2013 12:14:42 -0800 [thread overview]
Message-ID: <1360786482-881-2-git-send-email-dirk.brandewie@gmail.com> (raw)
In-Reply-To: <1360786482-881-1-git-send-email-dirk.brandewie@gmail.com>
From: Dirk Brandewie <dirk.brandewie@gmail.com>
Load order is important in order for intel_pstate to take over as the
default scaling driver from acpi-cpufreq.
If both are built-in acpi-cpufreq uses late_initcall() and
intel_pstate uses device_initcall() so it will be able to register as
the scaling before acpi-cpufreq for the processors supported by
intel_pstate.
If acpi-cpufreq is built as a module then intel_pstate still gets
first option to become the scaling driver.

This driver provides a P state for Intel core processors.

When this driver is enabled it will become the perferred
scaling driver for Sandy bridge processors.
- Note: This driver should be built with the same settings as
- the other scaling drivers configured into the system
- (module/built-in) in order for the driver to register itself
- as the scaling driver on the system.
