The primary changes involve the creation\nof dedicated directories for each driver within 'drivers/power/core/*' and\n'drivers/power/uncore/*'.\n \nThis refactor significantly improves code organization, enhances clarity,\nand boosts maintainability. It lays the foundation for more focused\ndevelopment on individual drivers and facilitates seamless integration of\nfuture enhancements, particularly the AMD uncore driver.\n \nFurthermore, this effort aims to streamline code maintenance by\nconsolidating common functions for cpufreq and cppc across various\ncore drivers, thus reducing code duplication. \n \nPlease note that this RFC patch is currently in its initial phase and is\nprimarily intended for soliciting feedback and comments. As of now,\nit has not undergone testing for build or functional issues.\n \nSigned-off-by: Sivaprasad Tummala <sivaprasad.tummala@amd.com>\n---\n power: refactor core power management library\n power: refactor uncore power management library\n\n drivers/meson.build | 1 +\n drivers/power/core/acpi/meson.build | 8 +\n .../power/core/acpi}/power_acpi_cpufreq.c | 19 ++\n .../power/core/acpi}/power_acpi_cpufreq.h | 0\n drivers/power/core/amd-pstate/meson.build | 8 +\n .../amd-pstate}/power_amd_pstate_cpufreq.c | 19 ++\n .../amd-pstate}/power_amd_pstate_cpufreq.h | 0\n drivers/power/core/cppc/meson.build | 8 +\n .../power/core/cppc}/power_cppc_cpufreq.c | 19 ++\n .../power/core/cppc}/power_cppc_cpufreq.h | 0\n .../power/core/kvm-vm}/guest_channel.c | 0\n .../power/core/kvm-vm}/guest_channel.h | 0\n drivers/power/core/kvm-vm/meson.build | 20 ++\n .../power/core/kvm-vm}/power_kvm_vm.c | 19 ++\n .../power/core/kvm-vm}/power_kvm_vm.h | 0\n drivers/power/core/meson.build | 12 +\n drivers/power/core/pstate/meson.build | 8 +\n .../power/core/pstate}/power_pstate_cpufreq.c | 19 ++\n .../power/core/pstate}/power_pstate_cpufreq.h | 0\n drivers/power/meson.build | 9 +\n drivers/power/uncore/intel/meson.build | 9 +\n .../power/uncore/intel}/power_intel_uncore.c | 15 +\n .../power/uncore/intel}/power_intel_uncore.h | 0\n drivers/power/uncore/meson.build | 8 +\n lib/power/meson.build | 7 -\n lib/power/power_common.h | 11 +\n lib/power/rte_power.c | 305 ++++++++----------\n lib/power/rte_power.h | 207 ++++++++++--\n lib/power/rte_power_uncore.c | 163 ++++------\n lib/power/rte_power_uncore.h | 150 ++++++++-\n lib/power/version.map | 13 +\n 31 files changed, 742 insertions(+), 315 deletions(-)\n create mode 100644 drivers/power/core/acpi/meson.build\n rename {lib/power => drivers/power/core/acpi}/power_acpi_cpufreq.c (95%)\n rename {lib/power => drivers/power/core/acpi}/power_acpi_cpufreq.h (100%)\n create mode 100644 drivers/power/core/amd-pstate/meson.build\n rename {lib/power => drivers/power/core/amd-pstate}/power_amd_pstate_cpufreq.c (95%)\n rename {lib/power => drivers/power/core/amd-pstate}/power_amd_pstate_cpufreq.h (100%)\n create mode 100644 drivers/power/core/cppc/meson.build\n rename {lib/power => drivers/power/core/cppc}/power_cppc_cpufreq.c (96%)\n rename {lib/power => drivers/power/core/cppc}/power_cppc_cpufreq.h (100%)\n rename {lib/power => drivers/power/core/kvm-vm}/guest_channel.c (100%)\n rename {lib/power => drivers/power/core/kvm-vm}/guest_channel.h (100%)\n create mode 100644 drivers/power/core/kvm-vm/meson.build\n rename {lib/power => drivers/power/core/kvm-vm}/power_kvm_vm.c (83%)\n rename {lib/power => drivers/power/core/kvm-vm}/power_kvm_vm.h (100%)\n create mode 100644 drivers/power/core/meson.build\n create mode 100644 drivers/power/core/pstate/meson.build\n rename {lib/power => drivers/power/core/pstate}/power_pstate_cpufreq.c (96%)\n rename {lib/power => drivers/power/core/pstate}/power_pstate_cpufreq.h (100%)\n create mode 100644 drivers/power/meson.build\n create mode 100644 drivers/power/uncore/intel/meson.build\n rename {lib/power => drivers/power/uncore/intel}/power_intel_uncore.c (95%)\n rename {lib/power => drivers/power/uncore/intel}/power_intel_uncore.h (100%)\n create mode 100644 drivers/power/uncore/meson.build" }
