If the mcpm backend is not available because the CCI is not defined in the DT, the cpuidle driver will unconditionally assume it is and call the mcpm functions leading to a kernel WARNING. Sudeep Holla fixed that by checking at the init time the mcpm is available before initializing the deeper idle states. Thanks -- Daniel The following changes since commit ec6f34e5b552fb0a52e6aae1a5afbbb1605cc6cc: Linux 3.19-rc5 (2015-01-18 18:02:20 +1200) are available in the git repository at: http://git.linaro.org/people/daniel.lezcano/linux.git cpuidle/3.20 for you to fetch changes up to 194fe6f28e2819d3f50fbed24c3b72f21501dbfa: drivers: cpuidle: Don't initialize big.LITTLE driver if MCPM is unavailable (2015-01-23 15:05:48 +0100) ---------------------------------------------------------------- Sudeep Holla (1): drivers: cpuidle: Don't initialize big.LITTLE driver if MCPM is unavailable drivers/cpuidle/cpuidle-big_little.c | 4 ++++ 1 file changed, 4 insertions(+) -- Linaro.org │ Open source software for ARM SoCs Follow Linaro: Facebook | Twitter | Blog
