Given the total size of the map is quite small, we can simply use a std::array of pairs and utilize std::find_if to perform the same behavior without loss of performance. This eliminates a static constructor and places the data into the read-only segment. While we're at it, we can also handle malformed inputs instead of directly dereferencing the resulting iterator. --- src/core/hle/service/apm/controller.cpp | 48 +++++++++++++++++++++++---------- 1 file changed, 34 insertions(+), 14 deletions(-) (limited to 'src') diff --git a/src/core/hle/service/apm/controller.cpp b/src/core/hle/service/apm/controller.cpp index d9e8d247d..25a886238 100644 --- a/src/core/hle/service/apm/controller.cpp +++ b/src/core/hle/service/apm/controller.cpp @@ -2,6 +2,10 @@ // Licensed under GPLv2 or any later version // Refer to the license.txt file included. +#include +#include +#include + #include "common/logging/log.h" #include "core/core_timing.h" #include "core/hle/service/apm/controller.h" @@ -9,8 +13,7 @@ namespace Service::APM { -constexpr PerformanceConfiguration DEFAULT_PERFORMANCE_CONFIGURATION = - PerformanceConfiguration::Config7; +constexpr auto DEFAULT_PERFORMANCE_CONFIGURATION = PerformanceConfiguration::Config7; Controller::Controller(Core::Timing::CoreTiming& core_timing) : core_timing{core_timing}, configs{ @@ -22,18 +25,35 @@ Controller::~Controller() = default; void Controller::SetPerformanceConfiguration(PerformanceMode mode, PerformanceConfiguration config) { - static const std::map PCONFIG_TO_SPEED_MAP{ - {PerformanceConfiguration::Config1, 1020}, {PerformanceConfiguration::Config2, 1020}, - {PerformanceConfiguration::Config3, 1224}, {PerformanceConfiguration::Config4, 1020}, - {PerformanceConfiguration::Config5, 1020}, {PerformanceConfiguration::Config6, 1224}, - {PerformanceConfiguration::Config7, 1020}, {PerformanceConfiguration::Config8, 1020}, - {PerformanceConfiguration::Config9, 1020}, {PerformanceConfiguration::Config10, 1020}, - {PerformanceConfiguration::Config11, 1020}, {PerformanceConfiguration::Config12, 1020}, - {PerformanceConfiguration::Config13, 1785}, {PerformanceConfiguration::Config14, 1785}, - {PerformanceConfiguration::Config15, 1020}, {PerformanceConfiguration::Config16, 1020}, - }; - - SetClockSpeed(PCONFIG_TO_SPEED_MAP.find(config)->second); + static constexpr std::array, 16> config_to_speed{{ + {PerformanceConfiguration::Config1, 1020}, + {PerformanceConfiguration::Config2, 1020}, + {PerformanceConfiguration::Config3, 1224}, + {PerformanceConfiguration::Config4, 1020}, + {PerformanceConfiguration::Config5, 1020}, + {PerformanceConfiguration::Config6, 1224}, + {PerformanceConfiguration::Config7, 1020}, + {PerformanceConfiguration::Config8, 1020}, + {PerformanceConfiguration::Config9, 1020}, + {PerformanceConfiguration::Config10, 1020}, + {PerformanceConfiguration::Config11, 1020}, + {PerformanceConfiguration::Config12, 1020}, + {PerformanceConfiguration::Config13, 1785}, + {PerformanceConfiguration::Config14, 1785}, + {PerformanceConfiguration::Config15, 1020}, + {PerformanceConfiguration::Config16, 1020}, + }}; + + const auto iter = std::find_if(config_to_speed.cbegin(), config_to_speed.cend(), + [config](const auto& entry) { return entry.first == config; }); + + if (iter == config_to_speed.cend()) { + LOG_ERROR(Service_APM, "Invalid performance configuration value provided: {}", + static_cast(config)); + return; + } + + SetClockSpeed(iter->second); configs.insert_or_assign(mode, config); } -- cgit v1.2.3
