Hi Krzysztof, Bartek,
I recall that you have been working on some cpuidle code for Exynos(4?).
I have a question regarding CPUIdle driver for Odroid XU4.
I use the board with LISA tests for EAS, but missing at
least idle state 0 cause errors (please see the log below).
Currently the system does not report any idle driver and the state 0
is missing in: /sys/devices/system/cpu/cpu0/cpuidle/state0/
I am using driver CONFIG_ARM_BIG_LITTLE_CPUIDLE but the
boot stops silently while trying to init the cpu idle devices in there.
I carry on with a workaround that just removes idle state[1] and set
state_count=1 in the big and little structures.
Could you tell me if it needs some out-of-tree patches or maybe special
bootloader or it is not possible at all to have this driver working
properly? Or maybe I should use different driver on that board?
