Exynos5420 is a big-little Soc from Samsung. It has 4 A15 and 4 A7 cores. This patchset adds cpuidle support for Exynos5420 SoC based on generic big.little cpuidle driver.Hi Chander, just a side question. I am not succeeding to have both cluster A7/A15 with the upstream kernel. How can I test your driver ?
Hmm on octa can be tested only for 4 cores. as cci is disabled.
Did I miss something ? Thanks -- Danielquoted
Tested on SMDK5420. This patch set depends on: 1. [PATCH 0/5] MCPM backend for Exynos5420 http://www.spinics.net/lists/arm-kernel/msg331100.html Changelog is in respective patches.
