[PATCH] spi: Only call transfer_one() if we have buffers to transfer

by Mark Brown

[PATCH 0/3] kdb: Infrastructure to display sequence files

by Daniel Thompson

This patchset started out as a simple patch to introduce the irqs command from Android's FIQ debugger to kdb. However it has since grown more powerful because allowing kdb to reuse existing kernel infrastructure gives us extra opportunities. Based on the comments at the top of irqdesc.h (plotting to take the irq_desc structure private to kernel/irq) and the relative similarity between FIQ debugger's irqs command and the contents /proc/interrupts we start by adding a kdb feature to print seq_files. This forms the foundation for a new command, interrupts. I have also been able to implement a much more generic command, seq_file, that can display a good number of files from pseudo filesystems. This command is very powerful although that power does mean care must be taken to deploy it safely. It is deliberately and by default aimed at your foot! Note that the risk associated with the seq_file command is why I implemented the interrupts command in C (in principle it could have been a kdb macro). Doing it in C codifies the need for show_interrupts() to continue using spin locks as its locking strategy. To give an idea of what can be done with this command. The following seq_operations structures worked correctly and report no errors: cpuinfo_op extfrag_op fragmentation_op gpiolib_seq_ops int_seq_ops (a.k.a. /proc/interrupts) pagetypeinfo_op unusable_op vmalloc_op zoneinfo_op The following display the information correctly but triggered errors (sleeping function called from invalid context) with lock debugging enabled: consoles_op crypto_seq_ops diskstats_op partitions_op slabinfo_op vmstat_op All tests are run on an ARM multi_v7_defconfig kernel (plus lots of debug features) and halted using magic SysRq so that kdb has interrupt context. Note also that some of the seq_operations structures hook into driver supplied code that will only be called if that driver is enabled so the test above are useful but cannot be exhaustive.

[RFC PATCH V2 00/19] Power Scheduler Design

by Preeti U Murthy

The new power aware scheduling framework is being designed with a goal that all the cpu power management is in one place. Today the power management policies are fragmented between the cpuidle and cpufreq subsystems, which makes power management inconsistent. To top this, we were integrating task packing algorithms into the scheduler which could potentially worsen the scenario. The new power aware scheduler design will have all policies, all metrics, all averaging concerning cpuidle and cpufrequency in one place, that being the scheduler. This patchset lays the foundation for this approach to help remove the existing fragmented approach towards cpu power savings. NOTE: This patchset targets only cpuidle. cpu-frequency can be integrated into this design on the same lines. The design is broken down into incremental steps which will enable easy validation of the power aware scheduler. This by no means is complete and will require more work to get to a stage where it can beat the current approach. Like I said this is just the foundation to help us get started. The subsequent patches can be small incremental measured steps. Ingo had pointed out this approach in http://lwn.net/Articles/552889/ and I have tried my best at understanding and implementing the initial steps that he suggested. 1.Start from the dumbest possible state: all CPUs are powered up fully, there's no idle state selection essentially. 2.Then go for the biggest effect first and add the ability to idle in a lower power state (with new functions and a low level driver that implements this for the platform with no policy embedded into it. 3.Implement the task packing algorithm. This patchset implements the above three steps and makes the fundamental design of power aware scheduler clear. It shows how: 1.The design should be non intrusive with the existing code. It should be enabled/disabled by a config switch. This way we can continue to work towards making it better without having to worry about regressing the kernel and yet have it in the kernel at the same time; a confidence booster that it is making headway. CONFIG_SCHED_POWER is the switch that makes the new code appear when turned on and disappear and default to the original code when turned off. 2.The design should help us test it better. Like Ingo pointed out: "Important: it's not a problem that the initial code won't outperform the current kernel's performance. It should outperform the _initial_ 'dumb' code in the first step. Then the next step should outperform the previous step, etc. The quality of this iterative approach will eventually surpass the combined effect of currently available but non-integrated facilities." This is precisely what this design does. PATCH[1/19] disables cpuidle and cpufrequency sub systems altogether if CONFIG_SCHED_POWER is enabled. This is the dumb code. Our subsequent patches should outperform this. 3. Introduce a low level driver which interfaces scheduler with C-state switching. Again Ingo had pointed out this saying: "It should be presented to the scheduler in a platform independent fashion, but without policy embedded: a low level platform driver interface in essence." PATCH[2/19] ensures that CPUIDLE governors no longer control idle state selection. The idle state selection and policies are moved into kernel/sched/power.c. True, its the same code from the menu governor, however it has been moved into scheduler specific code and no longer functions like a driver. Its meant to be part of the core kernel. The "low level driver" lives under drivers/cpuidle/cpuidle.c like before. It registers platform specific cpuidle drivers and does other low level stuff that the scheduler needn't bother about. It has no policies embedded into it whatsoever. Importantly it is an entry point to switching C states and nothing beyond that. PATCH[3/19] enumerates idle states and parameters in the scheduler topology. This is so that the scheduler knows the cost of entry/exit into idle states that can be made use of going ahead. As an example, this patchset shows how the platform specific cpuidle driver should help fill up the idle state details into the topology. This fundamental information is missing today in the scheduler. These two patches are not expected to change the performance/power savings in any way. They are just the first steps towards the integrated approach of the power aware scheduler. The patches PATCH[4/19] to PATCH[18/19] do task packing. This series is the one that Alex Shi had posted long ago https://lkml.org/lkml/2013/3/30/78. However this patch series will come into effect only if CONFIG_SCHED_POWER is enabled. It is this series which is expected to bring about changes in performance and power savings; not necessarily better than the existing code, but certainly should be better than the dumb code. Our subsequent efforts should surpass the performance/powersavings of the existing code. This patch series is compile tested only. V1 of this power efficient scheduling design was posted by Morten after Ingo posted his suggestions on http://lwn.net/Articles/552889/. [RFC][PATCH 0/9] sched: Power scheduler design proposal: https://lkml.org/lkml/2013/7/15/101 But it decoupled the scheduler into the regular and power scheduler with the latter controlling the cpus that could be used by the regular scheduler. We do not need this kind of decoupling. With the foundation that this patch set lays, it must be relatively easy to make the existing scheduler power aware. --- Alex Shi (16): sched: add sched balance policies in kernel sched: add sysfs interface for sched_balance_policy selection sched: log the cpu utilization at rq sched: add new sg/sd_lb_stats fields for incoming fork/exec/wake balancing sched: move sg/sd_lb_stats struct ahead sched: get rq potential maximum utilization sched: detect wakeup burst with rq->avg_idle sched: add power aware scheduling in fork/exec/wake sched: using avg_idle to detect bursty wakeup sched: packing transitory tasks in wakeup power balancing sched: add power/performance balance allow flag sched: pull all tasks from source grp and no balance for prefer_sibling sched: add new members of sd_lb_stats sched: power aware load balance sched: lazy power balance sched: don't do power balance on share cpu power domain Preeti U Murthy (3): sched/power: Remove cpu idle state selection and cpu frequency tuning sched/power: Move idle state selection into the scheduler sched/idle: Enumerate idle states in scheduler topology Documentation/ABI/testing/sysfs-devices-system-cpu | 23 + arch/powerpc/Kconfig | 1 arch/powerpc/platforms/powernv/Kconfig | 12 drivers/cpufreq/Kconfig | 2 drivers/cpuidle/Kconfig | 10 drivers/cpuidle/cpuidle-powernv.c | 10 drivers/cpuidle/cpuidle.c | 65 ++ include/linux/sched.h | 16 - include/linux/sched/sysctl.h | 3 kernel/Kconfig.sched | 11 kernel/sched/Makefile | 1 kernel/sched/debug.c | 3 kernel/sched/fair.c | 632 +++++++++++++++++++- kernel/sched/power.c | 480 +++++++++++++++ kernel/sched/sched.h | 16 + kernel/sysctl.c | 9 16 files changed, 1234 insertions(+), 60 deletions(-) create mode 100644 kernel/Kconfig.sched create mode 100644 kernel/sched/power.c --
