[PATCH] pm-qa: run sanity check before running test cases

by Rajagopal Venkat

From: root <root(a)linaro-ubuntu-desktop.(none)> run sanity test for each functionality if present. If functionality enabled, then run all respective test cases. This patch also adds sanity checks for cpuidle and sched_mc.

[PATCH v3 0/5] ARM: topology: set the capacity of each cores for big.LITTLE

by Vincent Guittot

This patchset creates an arch_scale_freq_power function for ARM, which is used to set the relative capacity of each core of a big.LITTLE system. It also removes the broken power estimation of x86. Modification since v2: - set_power_scale function becomes static - Rework loop in update_siblings_masks - Remove useless code in parse_dt_topology Modification since v1: - Add and update explanation about the use of the table and the range of the value - Remove the use of NR_CPUS and use nr_cpu_ids instead - Remove broken power estimation of x86 Peter Zijlstra (1): sched, x86: Remove broken power estimation Vincent Guittot (4): ARM: topology: Add arch_scale_freq_power function ARM: topology: factorize the update of sibling masks ARM: topology: Update cpu_power according to DT information sched: cpu_power: enable ARCH_POWER arch/arm/kernel/topology.c | 209 +++++++++++++++++++++++++++++++++++++----- arch/x86/kernel/cpu/Makefile | 2 +- arch/x86/kernel/cpu/sched.c | 55 ----------- kernel/sched/features.h | 2 +- 4 files changed, 189 insertions(+), 79 deletions(-) delete mode 100644 arch/x86/kernel/cpu/sched.c -- 1.7.9.5

[PATCH] acpi: intel_idle : break dependency between modules

by Daniel Lezcano

When the system is booted with some cpus offline, the idle driver is not initialized. When a cpu is set online, the acpi code call the intel idle init function. Unfortunately this code introduce a dependency between intel_idle and acpi. This patch is intended to remove this dependency by using the notifier of intel_idle. In order to make it work, the notifier must be initialized in the right order, acpi then intel_idle. This is done in the Makefile. This patch has the benefit of encapsulating the intel_idle driver and remove some exported functions.

[PATCH 0/7] add Power and Voltage Domain Support to Powerdebug

by evttxl＠gmail.com

From: Eric van Tassell <evt(a)evtM17x.(none)> Since my first attempt at doing this by analogy to what's already in powerdebug(tree of sysfs files) was rejected because reviewers didn't want to add a bunch more OMAP specific files to sysfs, I rewrote things in userland. There are a few basic chunks to the changes: 1) Add code to parse a CSV-like config file that defines a heirarchy of whatever form you want where the leaves are fields in mmio registers. Include decoders for the field values something easy to read (ex: "off" instead of 0) 2) A code to build a tree that the powerdebug framework walks from a CSV config file 3) A small bit of code to read the mmio regs via /dev/mem 4) One example config file each for Power & Voltage Domains. It's all tested on OMAP4430(panda) but the config file mechanism is completely general. Eric van Tassell (7): - add config files to define selected power domain and voltage domain registers for OMAP4430 add delimi.* to parse config files with clone of strchrnul - add support for reading memory mapped I/O registers via /dev/mem - add support to display fields of memory mapped I/O registers with optional value decoding as defined by config files - largest commit of this series. Provide an instance of the tree abstraction used by powerdebug core that is built by parsing a config file instead of walking a debugfs tree as, for example, the sensor functionality does - add display options for Voltage and Power domains - enable extended display function call - add options for power and voltage domains - call tree_mgr_new to create the objects that implement them - cleanup Android.mk | 4 +- Makefile | 4 +- delimi.c | 106 +++++++++++++++++++ delimi.h | 30 ++++++ dirtree.c | 149 +++++++++++++++++++++++++++ dirtree.h | 22 ++++ display.c | 30 +++++- display.h | 4 +- mainloop.c | 2 + mmioreg.c | 77 ++++++++++++++ mmioreg.h | 27 +++++ powerdebug.c | 56 +++++++++-- pwrdm.regdefs.omap4 | 33 ++++++ regfield.c | 279 +++++++++++++++++++++++++++++++++++++++++++++++++++ regfield.h | 52 ++++++++++ tree.c | 28 ++++++ tree.h | 11 +- tree_mgr.c | 203 +++++++++++++++++++++++++++++++++++++ tree_mgr.h | 25 +++++ utils.c | 69 +++++++++++++ utils.h | 15 ++- vdd.regdefs.omap4 | 68 +++++++++++++ 22 files changed, 1275 insertions(+), 19 deletions(-) create mode 100644 delimi.c create mode 100644 delimi.h create mode 100644 dirtree.c create mode 100644 dirtree.h create mode 100644 mmioreg.c create mode 100644 mmioreg.h create mode 100644 pwrdm.regdefs.omap4 create mode 100644 regfield.c create mode 100644 regfield.h create mode 100644 tree_mgr.c create mode 100644 tree_mgr.h create mode 100644 vdd.regdefs.omap4 -- 1.7.9.5

first version of Linux Linaro Maintenance script is published

by Andrey Konovalov

Greetings, I've published the current version of the script used to maintain the Linux Linaro kernel trees. It is still at early stages of the development, and has a big room for enhancements and improvements. Nevertheless, it can recreate the earlier trees from the pinned manifests (and do some other stuff). For some more details see https://wiki.linaro.org/Platform/DevPlatform/LinuxLinaroKernelTreeProcess#L… If interested, you can use ll-fold.sh in the way described at the wiki page above at your own risk :) Thanks, Andrey
