A small task is defined as one +whose tracked load is less than 90% of a NICE_0 task. This is a change +from the usual behavior since the scheduler will normally use an idle +CPU for a waking task unless that task is considered cache hot. + + +How is it implemented? +---- +Since all small tasks must wake up relatively frequently, the main +requirement for packing small tasks is to select a partly-busy CPU when +waking rather than looking for an idle CPU. We use the tracked load of +the CPU runqueue to determine how heavily loaded each CPU is and the +tracked load of the task to determine if it will fit on the CPU. We +always start with the lowest-numbered CPU in a sched domain and stop +looking when we find a CPU with enough space for the task. + +Some further tweaks are necessary to suppress load balancing when the +CPU is not fully loaded, otherwise the scheduler attempts to spread +tasks evenly across the domain. + + +How does it interact with the HMP patches? +---- +Firstly, we only enable packing on the little domain. The intent is that +the big domain is intended to spread tasks amongst the available CPUs +one-task-per-CPU. The little domain however is attempting to use as +little power as possible while servicing its tasks. + +Secondly, since we offload big tasks onto little CPUs in order to try +to devote one CPU to each task, we have a threshold above which we do +not try to pack a task and instead will select an idle CPU if possible. +This maintains maximum forward progress for busy tasks temporarily +demoted from big CPUs. + + +Can the behaviour be tuned? +---- +Yes, the load level of a 'full' CPU can be easily modified in the source +and is exposed through sysfs as /sys/kernel/hmp/packing_limit to be +changed at runtime. The presence of the packing behaviour is controlled +by CONFIG_SCHED_HMP_LITTLE_PACKING and can be disabled at run-time +using /sys/kernel/hmp/packing_enable. +The definition of a small task is hard coded as 90% of NICE_0_LOAD +and cannot be modified at run time. + + +Why do I need to tune it? +---- +The optimal configuration is likely to be different depending upon the +design and manufacturing of your SoC. + +In the main, there are two system effects from enabling small task +packing. + +1. CPU operating point may increase +2. wakeup latency of tasks may be increased + +There are also likely to be secondary effects from loading one CPU +rather than spreading tasks. + +Note that all of these system effects are dependent upon the workload +under consideration. + + +CPU Operating Point +---- +The primary impact of loading one CPU with a number of light tasks is to +increase the compute requirement of that CPU since it is no longer idle +as often. Increased compute requirement causes an increase in the +frequency of the CPU through CPUfreq. + +Consider this example: +We have a system with 3 CPUs which can operate at any frequency between +350MHz and 1GHz. The system has 6 tasks which would each produce 10% +load at 1GHz. The scheduler has frequency-invariant load scaling +enabled. Our DVFS governor aims for 80% utilization at the chosen +frequency. + +Without task packing, these tasks will be spread out amongst all CPUs +such that each has 2. This will produce roughly 20% system load, and +the frequency of the package will remain at 350MHz. + +With task packing set to the default packing_limit, all of these tasks +will sit on one CPU and require a package frequency of ~750MHz to reach +80% utilization. (0.75 = 0.6 * 0.8). + +When a package operates on a single frequency domain, all CPUs in that +package share frequency and voltage. + +Depending upon the SoC implementation there can be a significant amount +of energy lost to leakage from idle CPUs. The decision about how +loaded a CPU must be to be considered 'full' is therefore controllable +through sysfs (sys/kernel/hmp/packing_limit) and directly in the code. + +Continuing the example, lets set packing_limit to 450 which means we +will pack tasks until the total load of all running tasks >= 450. In +practise, this is very similar to a 55% idle 1Ghz CPU. + +Now we are only able to place 4 tasks on CPU0, and two will overflow +onto CPU1. CPU0 will have a load of 40% and CPU1 will have a load of +20%. In order to still hit 80% utilization, CPU0 now only needs to +operate at (0.4*0.8=0.32) 320MHz, which means that the lowest operating +point will be selected, the same as in the non-packing case, except that +now CPU2 is no longer needed and can be power-gated. + +In order to use less energy, the saving from power-gating CPU2 must be +more than the energy spent running CPU0 for the extra cycles. This +depends upon the SoC implementation. + +This is obviously a contrived example requiring all the tasks to +be runnable at the same time, but it illustrates the point. + + +Wakeup Latency +---- +This is an unavoidable consequence of trying to pack tasks together +rather than giving them a CPU each. If you cannot find an acceptable +level of wakeup latency, you should turn packing off. + +Cyclictest is a good test application for determining the added latency +when configuring packing. + + +Why is it turned off for the VersatileExpress V2P_CA15A7 CoreTile? +---- +Simply, this core tile only has power gating for the whole A7 package. +When small task packing is enabled, all our low-energy use cases +normally fit onto one A7 CPU. We therefore end up with 2 mostly-idle +CPUs and one mostly-busy CPU. This decreases the amount of time +available where the whole package is idle and can be turned off. + diff -Nur linux-3.10.30/Documentation/devicetree/bindings/arm/cci.txt linux-3.10.30-cubox-i/Documentation/devicetree/bindings/arm/cci.txt --- linux-3.10.30/Documentation/devicetree/bindings/arm/cci.txt 1970-01-01 01:00:00.000000000 +0100 +++ linux-3.10.30-cubox-i/Documentation/devicetree/bindings/arm/cci.txt 2014-03-08 20:32:51.000000000 +0100 @@ -0,0 +1,172 @@ +======================================================= +ARM CCI cache coherent interconnect binding description +======================================================= + +ARM multi-cluster systems maintain intra-cluster coherency through a +cache coherent interconnect (CCI) that is capable of monitoring bus +transactions and manage coherency, TLB invalidations and memory barriers. + +It allows snooping and distributed virtual memory message broadcast across +clusters, through memory mapped interface, with a global control register +space and multiple sets of interface control registers, one per slave +interface. + +Bindings for the CCI node follow the ePAPR standard, available from: + +www.power.org/documentation/epapr-version-1-1/ + +with the addition of the bindings described in this document which are +specific to ARM. + +* CCI interconnect node + + Description: Describes a CCI cache coherent Interconnect component + + Node name must be "cci". + Node's parent must be the root node /, and the address space visible + through the CCI interconnect is the same as the one seen from the + root node (ie from CPUs perspective as per DT standard). + Every CCI node has to define the following properties: + + - compatible + Usage: required + Value type: + Definition: must be set to + "arm,cci-400" + + - reg + Usage: required + Value type: + Definition: A standard property.
