Subject: [PATCH 1/6] powernow-k8: Add a kconfig dependency on acpi-cpufreq
Date: Sun, 20 Jan 2013 11:24:25 +0100 [thread overview]
Message-ID: <1358677470-17394-2-git-send-email-bp@alien8.de> (raw)
In-Reply-To: <1358677470-17394-1-git-send-email-bp@alien8.de>
From: Borislav Petkov <bp@suse.de>
Andreas reports in https://bugzilla.kernel.org/show_bug.cgi?id=51741
that with his Gentoo config, acpi-cpufreq wasn't enabled and powernow-k8
couldn't handoff properly to acpi-cpufreq leading to running without
P-state support (i.e., cores are constantly in P0).
To alleaviate that, we need to make powernow-k8 depend on acpi-cpufreq
so that acpi-cpufreq is always present.

This adds the CPUFreq driver for K8/early Opteron/Athlon64 processors.
Support for K10 and newer processors is now in acpi-cpufreq.
