In preparation for this enhance the existing powercap/idle_inject and modify intel_powerclamp to use this. Then add per core idle injection driver. v2 - Update based on feedback from Rafael on patch 2/4 - Kconfig dependency issue Reported-by: kernel test robot Srinivas Pandruvada (4): powercap: idle_inject: Export symbols powercap: idle_inject: Add prepare/complete callbacks thermal/drivers/intel_powerclamp: Use powercap idle-inject framework thermal/drivers/intel_cpu_idle_cooling: Introduce Intel cpu idle cooling driver drivers/powercap/idle_inject.c | 69 ++++- drivers/thermal/intel/Kconfig | 12 + drivers/thermal/intel/Makefile | 1 + .../thermal/intel/intel_cpu_idle_cooling.c | 261 ++++++++++++++++ drivers/thermal/intel/intel_powerclamp.c | 292 ++++++++---------- include/linux/idle_inject.h | 4 + 6 files changed, 467 insertions(+), 172 deletions(-) create mode 100644 drivers/thermal/intel/intel_cpu_idle_cooling.c Acked-by: Rafael J.
