Subject: [RFC PATCH 0/4] ARM: remove big.LITTLE switcher support
Date: Mon, 27 Jun 2016 13:26:06 +0200 [thread overview]
Message-ID: <1467026770-5699-1-git-send-email-b.zolnierkie@samsung.com> (raw)
Hi,
It seems that in mainline kernel big.LITTLE switcher support
may be usable only on ARM Versatile Express TC2 platform
(but even this platform doesn't enable it in its defconfig).
The following patchset removes big.LITTLE switcher support
(from both ARM core and arm_big_little CPUfreq driver) in
favor of using HMP.
Since HMP support at scheduler level is not yet merged this
patchset is probably premature and thus is marked as RFC.
Best regards,
