Hi all, This is the revised patchset after good discussions at Plumbers' conference. So far, the design fashioned a PM domain around a cluster of CPUs. After discussions, it was agreed that each CPU will be considered a PM domain, for it can be powered on/off individually. This series implements that change. This set adds support for CPU PM domains. One of users of CPU PM Domains is PSCI on ARM architectures. A following patchset will add that support. Changes since V4[1]: - CPU PM domains re-organized - Update patchset to use hotplug mechanism - Rebase on top of rwy/linux-next The patches do the following - #1: Allows CPU's idle states be presented using domain-idle-states property #2,#3: Add runtime PM support for CPU devices #4: Create PM domains for CPUs #5: Export timer for CPU wakeup #6: Determine CPU cluster wakeup #7,#8: Data and DT support for CPU PM domains #9: Add Documentation Thanks, Lina [1]. http://lists.infradead.org/pipermail/linux-arm-kernel/2016-October/463419.html Lina Iyer (9): PM / Domains: Ignore domain-idle-states that are not compatible drivers: cpu: Setup CPU devices to do runtime PM kernel/cpu_pm: Add runtime PM support for CPUs PM / cpu_domains: Setup PM domains for CPUs/clusters timer: Export next wake up of a CPU PM / cpu_domains: Add PM Domain governor for CPUs PM / Domains: allow platform specific data for genpd states PM / cpu_domains: Initialize CPU PM domains from DT doc / cpu_domains: Describe CPU PM domains setup and governor .../devicetree/bindings/power/power_domain.txt | 4 +- Documentation/power/cpu_domains.txt | 109 +++++ drivers/base/cpu.c | 15 + drivers/base/power/Makefile | 2 +- drivers/base/power/cpu_domains.c | 480 +++++++++++++++++++++ drivers/base/power/domain.c | 16 +- include/linux/cpu_domains.h | 68 +++ include/linux/cpuhotplug.h | 1 + include/linux/pm_domain.h | 1 + include/linux/tick.h | 10 + kernel/cpu_pm.c | 47 ++ kernel/time/tick-sched.c | 11 + 12 files changed, 755 insertions(+), 9 deletions(-) create mode 100644 Documentation/power/cpu_domains.txt create mode 100644 drivers/base/power/cpu_domains.c create mode 100644 include/linux/cpu_domains.h -- 2.7.4 -- To unsubscribe from this list: send the line "unsubscribe linux-arm-msm" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
