[PATCH V3 00/16] PM / OPP: Introduce APIs to transition OPPs

by Viresh Kumar

Hi Guys, This patchset add APIs in OPP layer to allow OPPs transitioning from within OPP layer. Currently all OPP users need to replicate the same code to switch between OPPs. While the same can be handled easily by OPP-core. The first 7 patches update the OPP core to introduce the new APIs and the next Nine patches update cpufreq-dt for the same. 11 out of 17 are already Reviewed by Stephen, only few are left :) I hope this is the last version of the series :) Testing: - Tested on exynos 5250-arndale (dual-cortex-A15) - Tested for both Old-V1 bindings and New V2 bindings - Tested with regulator names as: 'cpu-supply' and 'cpu0-supply' - Tested with Unsupported supply ranges as well, to check the opp-disable logic V2->V3: - Very minor updates. - find_supply_name() doesn't return an error value now, and so its callers don't check for it. - And so we don't need to initialize name to NULL Viresh Kumar (16): PM / OPP: get/put regulators from OPP core PM / OPP: Disable OPPs that aren't supported by the regulator PM / OPP: Introduce dev_pm_opp_get_max_volt_latency() PM / OPP: Introduce dev_pm_opp_get_max_transition_latency() PM / OPP: Parse clock-latency and voltage-tolerance for v1 bindings PM / OPP: Manage device clk PM / OPP: Add dev_pm_opp_set_rate() cpufreq: dt: Convert few pr_debug/err() calls to dev_dbg/err() cpufreq: dt: Rename 'need_update' to 'opp_v1' cpufreq: dt: OPP layers handles clock-latency for V1 bindings as well cpufreq: dt: Pass regulator name to the OPP core cpufreq: dt: Unsupported OPPs are already disabled cpufreq: dt: Reuse dev_pm_opp_get_max_transition_latency() cpufreq: dt: Use dev_pm_opp_set_rate() to switch frequency cpufreq: dt: No need to fetch voltage-tolerance cpufreq: dt: No need to allocate resources anymore drivers/base/power/opp/core.c | 420 ++++++++++++++++++++++++++++++++++++++++++ drivers/base/power/opp/opp.h | 13 ++ drivers/cpufreq/cpufreq-dt.c | 300 +++++++++++------------------- include/linux/pm_opp.h | 27 +++ 4 files changed, 565 insertions(+), 195 deletions(-) -- 2.7.1.370.gb2aa7f8

[PATCH 00/34] CPUFreq: Move freq change notifications out of drivers

by Viresh Kumar

Another 452 lines gone :) Total stats upto now for all the 5 patchsets: Viresh Kumar (186): ... 69 files changed, 700 insertions(+), 2451 deletions(-) Net: 1751 lines gone.. -----x-------------x---------------- Most of the drivers do following in their ->target_index() routines: struct cpufreq_freqs freqs; freqs.old = old freq... freqs.new = new freq... cpufreq_notify_transition(policy, &freqs, CPUFREQ_PRECHANGE); /* Change rate here */ cpufreq_notify_transition(policy, &freqs, CPUFREQ_POSTCHANGE); This is replicated over all cpufreq drivers today and there doesn't exists a good enough reason why this shouldn't be moved to cpufreq core instead. There are few special cases though, like exynos5440, which doesn't do everything on the call to ->target_index() routine and call some kind of bottom halves for doing this work, work/tasklet/etc.. They may continue doing notification from their own code and so this patch introduces another flag: CPUFREQ_NO_NOTIFICATION, which will be set by such drivers. This is Fifth part of my cleanup work for CPUFreq, first three are (And obviously its rebased over them): 1: cpufreq: Introduce cpufreq_table_validate_and_show() https://lkml.org/lkml/2013/8/8/263 2: cpufreq: define generic routines for cpufreq drivers https://lkml.org/lkml/2013/8/10/48 3.

[PATCH V4 0/9] PM / Domains: Implement domain performance states

by Viresh Kumar

Hi, The main feedback I got for the V3 series came from Kevin, who suggested that we should reuse OPP tables for genpd devices as well, instead of creating a new table type. And that's what this version is trying to do. Some platforms have the capability to configure the performance state of their power domains. The process of configuring the performance state is pretty much platform dependent and we may need to work with a wide range of configurables. For some platforms, like Qcom, it can be a positive integer value alone, while in other cases it can be voltage levels, etc. The power-domain framework until now was only designed for the idle state management of the device and this needs to change in order to reuse the power-domain framework for active state management of the devices. This series adapts the genpd and OPP frameworks to allow OPP tables to be used for the genpd devices as well. The first 2 patches update the DT bindings of the power-domains and OPP tables. And the other 7 patches implement the details in QoS, genpd and OPP frameworks. This is tested currently by hacking the kernel a bit with virtual power-domains for the dual A15 exynos platform. The earlier version of patches was also tested by Rajendra Nayak (Qcom) on *real* Qualcomm hardware for which this work is getting done. And so this version should work as well. Here is sample DT and C code we need to write for platforms: DT: --- / { domain_opp_table: opp_table0 { compatible = "operating-points-v2"; opp@1 { domain-performance-state = <1>; opp-microvolt = <975000 970000 985000>; }; opp@2 { domain-performance-state = <2>; opp-microvolt = <1075000 1000000 1085000>; }; }; foo_domain: power-controller@12340000 { compatible = "foo,power-controller"; reg = <0x12340000 0x1000>; #power-domain-cells = <0>; operating-points-v2 = <&domain_opp_table>; } cpu0_opp_table: opp_table1 { compatible = "operating-points-v2"; opp-shared; opp@1000000000 { opp-hz = /bits/ 64 <1000000000>; domain-performance-state = <1>; }; opp@1100000000 { opp-hz = /bits/ 64 <1100000000>; domain-performance-state = <2>; }; opp@1200000000 { opp-hz = /bits/ 64 <1200000000>; domain-performance-state = <2>; }; }; cpus { #address-cells = <1>; #size-cells = <0>; cpu@0 { compatible = "arm,cortex-a9"; reg = <0>; clocks = <&clk_controller 0>; clock-names = "cpu"; operating-points-v2 = <&cpu0_opp_table>; power-domains = <&foo_domain>; }; }; }; Driver code: ------------ static int pd_performance(struct generic_pm_domain *domain, unsigned int state) { struct dev_pm_opp *opp; opp = dev_pm_opp_find_dps(&domain->dev, state, true); /* Use OPP and state in platform specific way */ return 0; } static const struct of_device_id pm_domain_of_match[] __initconst = { { .compatible = "foo,genpd", }, { }, }; static int __init genpd_test_init(void) { struct device *dev = get_cpu_device(0); struct device_node *np; const struct of_device_id *match; int n; int ret; for_each_matching_node_and_match(np, pm_domain_of_match, &match) { pd.name = kstrdup_const(strrchr(np->full_name, '/') + 1, GFP_KERNEL); if (!pd.name) { of_node_put(np); return -ENOMEM; } pd.set_performance_state = pd_performance; pm_genpd_init(&pd, NULL, false); of_genpd_add_provider_simple(np, &pd); } ret = dev_pm_domain_attach(dev, false); return ret; } Pushed here as well: https://git.linaro.org/people/viresh.kumar/linux.git/log/?h=opp/genpd-perfo… V3->V4: - Use OPP table for genpd devices as well. - Add struct device to genpd, in order to reuse OPP infrastructure. - Based over: https://marc.info/?l=linux-kernel&m=148972988002317&w=2 - Fixed examples in DT document to have voltage in target,min,max order. V2->V3: - Based over latest pm/linux-next - Bindings and code are merged together - Lots of updates in bindings - the performance-states node is present within the power-domain now, instead of its phandle. - performance-level property is replaced by "reg". - domain-performance-state property of the consumers contain an integer value now instead of phandle. - Lots of updates to the code as well - Patch "PM / QOS: Add default case to the switch" is merged with other patches and the code is changed a bit as well. - Don't pass 'type' to dev_pm_qos_add_notifier(), rather handle all notifiers with a single list. A new patch is added for that. - The OPP framework patch can be applied now and has proper SoB from me. - Dropped "PM / domain: Save/restore performance state at runtime suspend/resume". - Drop all WARN(). - Tested-by Rajendra nayak. V1->V2: - Based over latest pm/linux-next - It is mostly a resend of what is sent earlier as this series hasn't got any reviews so far and Rafael suggested that its better I resend it. - Only the 4/6 patch got an update, which was shared earlier as reply to V1 as well.

[RFC 0/9] cpufreq: schedutil: Allow remote wakeups

by Viresh Kumar

Hi, This is based of the work done by Steve Muckle [1] before he left Linaro and most of the patches are still under his authorship. I have done couple of improvements (detailed in individual patches) and removed the late callback support [2] as I wasn't sure of the value it adds. We can include it separately if others feel it is required. This series is based on pm/linux-next with patches [3] and [4] applied on top of it. With Android UI and benchmarks the latency of cpufreq response to certain scheduling events can become very critical. Currently, callbacks into schedutil are only made from the scheduler if the target CPU of the event is the same as the current CPU. This means there are certain situations where a target CPU may not run schedutil for some time. One testcase to show this behavior is where a task starts running on CPU0, then a new task is also spawned on CPU0 by a task on CPU1. If the system is configured such that new tasks should receive maximum demand initially, this should result in CPU0 increasing frequency immediately. Because of the above mentioned limitation though this does not occur. This is verified using ftrace with the sample [5] application. This patchset updates the scheduler to call cpufreq callbacks for remote CPUs as well and updates schedutil governor to deal with it. An additional flag is added to cpufreq policies to avoid sending IPIs to remote CPUs to update the frequency, if CPUs on the platform can change frequency of any other CPU. This series is tested with couple of usecases (Android: hackbench, recentfling, galleryfling, vellamo, Ubuntu: hackbench) on ARM hikey board (64 bit octa-core, single policy). Only galleryfling showed minor improvements, while others didn't had much deviation. The reason being that this patchset only targets a corner case, where following are required to be true to improve performance and that doesn't happen too often with these tests: - Task is migrated to another CPU. - The task has maximum demand initially, and should take the CPU to higher OPPs. - And the target CPU doesn't call into schedutil until the next tick, without this patchset. -- viresh [1] https://git.linaro.org/people/steve.muckle/kernel.git/log/?h=pmwg-integrati… [2] https://git.linaro.org/people/steve.muckle/kernel.git/commit/?h=pmwg-integr… [3] https://marc.info/?l=linux-kernel&m=148766093718487&w=2 [4] https://marc.info/?l=linux-kernel&m=148903231720432&w=2 [5] http://pastebin.com/7LkMSRxE Steve Muckle (8): sched: cpufreq: add cpu to update_util_data irq_work: add irq_work_queue_on for !CONFIG_SMP sched: cpufreq: extend irq work to support fast switches sched: cpufreq: remove smp_processor_id() in remote paths sched: cpufreq: detect, process remote callbacks cpufreq: governor: support scheduler cpufreq callbacks on remote CPUs intel_pstate: ignore scheduler cpufreq callbacks on remote CPUs sched: cpufreq: enable remote sched cpufreq callbacks Viresh Kumar (1): cpufreq: Add dvfs_possible_from_any_cpu policy flag drivers/cpufreq/cpufreq-dt.c | 1 + drivers/cpufreq/cpufreq_governor.c | 2 +- drivers/cpufreq/intel_pstate.c | 3 ++ include/linux/cpufreq.h | 9 +++++ include/linux/irq_work.h | 7 ++++ include/linux/sched/cpufreq.h | 1 + kernel/sched/cpufreq.c | 1 + kernel/sched/cpufreq_schedutil.c | 80 +++++++++++++++++++++++++++++--------- kernel/sched/fair.c | 6 ++- kernel/sched/sched.h | 3 +- 10 files changed, 90 insertions(+), 23 deletions(-) -- 2.7.1.410.g6faf27b

[PATCH 00/17] thermal: cpu_cooling: improve interaction with cpufreq core

by Viresh Kumar

Hi Guys, The cpu_cooling driver is designed to use CPU frequency scaling to avoid high thermal states for a platform. But it wasn't glued really well with cpufreq core. This series tries to improve interactions between cpufreq core and cpu_cooling driver and does some fixes/cleanups to the cpu_cooling driver. I am a bit confused about which tree this series should go through, PM or thermal. This series has dependency on few other patches which are already merged in the PM [1] tree and thermal [2] tree. As this is 4.12 material, all of this should go through only one tree to avoid conflicts. I assume that one of Rafael and Rui have to drop the existing patch(es) from their trees and let the other one apply all of these. I would let you guys decide on that. Sorry for the trouble. I have tested it on ARM 32 (exynos) and 64 bit (hikey) boards and have pushed them for 0-day build bot and kernel CI testing as well. We should know if something is broken with these. @Javi: It would be good if you can give them a test, specially because of your work on the "power" specific bits in the driver.
