Attendees:
Linaro: Amit Kucheria, Amit Arora, Vishwanath Sripathy, Yong Shen ARM: Srinivas Kalaga, Robin Randhawa
== Action Items from this Meeting == * ACTION: Amit A to get review and then post powertop patches to powertop list upstream * ACTION: Amit A to look at power supply framework * ACTION: Amit K to look at getting powertop kernel patches applied to Linaro kernel tree * ACTION: Vishwa to send instrumentation patches to linaro-dev * ACTION: Vishwa to send usecase to reproduce ondemand governor problems * ACTION: Amit K to spend some time on usecase to reproduce ondemand governor problems
== Action Items from Previous Meeting == * ACTIVE (Immediate): * ACTION: Robin and Srinivas to target the ftrace patches for upstream.: OPEN * Srinivas to clarify what tree/branch is being used for this work * ACTION: Amit K to send email regarding power aware scheduling by Intel (CONFIG_SCHED_MC & CONFIG_SCHED_SMT ?) Yes! : DONE * /sys/devices/system/cpu/sched_* * ACTION: Yong Shen to test Amit Arora's powertop patches and powerdebug tool: DONE * ACTION: Yong Shen to investigate plugging in cpufreq framework for freescale boards: DONE * ACTION: Amit Arora to creat a new wiki page for instructions on how to setup your own git repo on git.linaro.org : DONE * https://wiki.linaro.org/Process/GitHostingAccounts * ACTION: Amit K to talk to jeremy about power domain framework: DONE * Jeremy needs help, will revisit in a few weeks * ACTION: Amit Arora and Yong to discuss about reporting sensor information (hwmon, or some other source for ARM?): DONE
== Minutes == * Reporting sensor information (hwmon, or some other source for ARM?): DONE * hwmon not much used * camera goes to v4l * battery goes to supply class * omap4 - temperature sensor exported to hwmon * power supply class support to be added to powerdebug * Blueprint status * Tools : Amit has posted a new request to test and review the patest powertop patches. Waiting for feedback. * cpuidle: instrumentation work being tested, OFF mode is broken. Will post patches to linaro-dev * HW Governor * Freescale chips produce interrupts based on cpu load (DVFS controller) o load thresholds programmed into drivers o the load calculation window is programmable??? * OMAP doesn't have anything similar o something exists for L3 load * SW governors o ondemand governor period is constant
