Subject: [PATCH 0/3] cpuidle: (powernv) cpuidle driver.
Date: Tuesday 23rd July 2013 09:01:22 UTC (over 3 years ago)
Following patch series ports the cpuidle framework for powernv platform and also implements a cpuidle back-end powernv idle driver calling on to power7_nap and snooze idle states. Moving the idle states over to cpuidle framework can take advantage of advanced heuristics, tunables and features provided by cpuidle framework. Additional idle states can be exploited using the cpuidle framework. The statistics and tracing infrastructure provided by the cpuidle framework also helps in enabling power management related tools and help tune the system and applications. This series aims to maintain compatibility and functionality to existing powernv idle cpu management code. There are no new functions or idle states added as part of this series. This can be extended by adding more states to this existing framework. With this patch series the powernv cpuidle functionalities are on-par with pSeries idle management. For POWERNV platform to hook into CPUIDLE framework, one needs to enable CONFIG_POWERNV_IDLE and disable CONFIG_PSERIES_IDLE Deepthi Dharwar (3): cpuidle/powernv: cpuidle backend driver for powernv cpuidle/powernv: Enable idle powernv cpu to call into the cpuidle framework. cpuidle/powernv: Support smt-snooze-delay parameter in powernv idle. arch/powerpc/include/asm/processor.h | 2 arch/powerpc/platforms/powernv/Kconfig | 9 + arch/powerpc/platforms/powernv/Makefile | 1 arch/powerpc/platforms/powernv/powernv.h | 3 arch/powerpc/platforms/powernv/processor_idle.c | 275 +++++++++++++++++++++++ arch/powerpc/platforms/powernv/setup.c | 12 + 6 files changed, 300 insertions(+), 2 deletions(-) create mode 100644 arch/powerpc/platforms/powernv/processor_idle.c -- Deepthi
