Hi, Can someone please suggest the full set of kernel config options need to set before running powertop. The readme file suggests that the list is incomplete. Kernel Parameters: ------------------ PowerTOP needs some kernel config options enabled in order function properly. As of linux-3.3.0 these are (list probably incomplete): CONFIG_NO_HZ CONFIG_HIGH_RES_TIMERS CONFIG_HPET_TIMER CONFIG_CPU_FREQ_GOV_ONDEMAND CONFIG_USB_SUSPEND CONFIG_SND_AC97_POWER_SAVE CONFIG_TIMER_STATS CONFIG_PERF_EVENTS CONFIG_PERF_COUNTERS CONFIG_TRACEPOINTS CONFIG_TRACING CONFIG_EVENT_POWER_TRACING_DEPRECATED CONFIG_X86_MSR ACPI_PROCFS_POWER CONFIG_DEBUG_FS The patches in the patches/ sub-directory are required for PowerTOP to function fully.(where to look for the patch folder ?could not figure out the patch folder in release directory) Regards adrip From: Mukherjee, Adrip Sent: 20 November 2013 17:03 To: powertop@lists.01.org<mailto:powertop@lists.01.org> Subject: PowerTop Installation issue Hi , This is Adrip from Intel India PCCG group. Recently I was trying to install powertop in my HSW PVT2 system having Android JellyBean internal version . According to the installation steps listed here: To build and install PowerTOP type the following commands, ./configure ./make ./make install Its failing to configure with a message : "permission denied" even though I have rooted my terminal emulator. Can you please tell me what I need to follow to run the powertop tool on Android in a Haswell SDS system. regards Adrip
