[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.

[PATCH V6 0/9] PM / Domains: Implement domain performance states

by Viresh Kumar

Hi, Here is the 6th version of the series, which incorporates feedback from Kevin and Sudeep: - Use freq/voltage in OPP table as it is for power domain and don't create "domain-performance-level" property - Take care of domain providers that provide multiple domains Here is a brief summary of the problem I am trying to solve. 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. Hope 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"; domain_opp_1: opp-1 { opp-hz = /bits/ 64 <1>; opp-microvolt = <975000 970000 985000>; }; domain_opp_2: opp-2 { opp-hz = /bits/ 64 <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>; power-domain-opp = <&domain_opp_1>; }; opp-1100000000 { opp-hz = /bits/ 64 <1100000000>; power-domain-opp = <&domain_opp_2>; }; opp-1200000000 { opp-hz = /bits/ 64 <1200000000>; power-domain-opp = <&domain_opp_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_freq_exact(&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… V5->V6: - Use freq/voltage in OPP table as it is for power domain and don't create "domain-performance-level" property - Create new "power-domain-opp" property for the devices. - Take care of domain providers that provide multiple domains and extend "operating-points-v2" property to contain a list of phandles - Update code according to those bindings.
