From e05d2a70b24e550d67fcdd24aae7094ad41745f8 Mon Sep 17 00:00:00 2001 From: Lioncash Date: Mon, 13 Dec 2021 21:09:28 -0500 Subject: common/input: Avoid numerous large copies of CallbackStatus CallbackStatus instances aren't the cheapest things to copy around (relative to everything else), given that they're currently 520 bytes in size and are currently copied numerous times when callbacks are invoked. Instead, we can pass the status by const reference to avoid all the copying. --- src/core/hid/emulated_console.cpp | 21 ++++++++++++--------- 1 file changed, 12 insertions(+), 9 deletions(-) (limited to 'src/core/hid/emulated_console.cpp') diff --git a/src/core/hid/emulated_console.cpp b/src/core/hid/emulated_console.cpp index 80db8e9c6..685ec080c 100644 --- a/src/core/hid/emulated_console.cpp +++ b/src/core/hid/emulated_console.cpp @@ -66,9 +66,10 @@ void EmulatedConsole::ReloadInput() { motion_devices = Common::Input::CreateDevice(motion_params); if (motion_devices) { - Common::Input::InputCallback motion_callback{ - [this](Common::Input::CallbackStatus callback) { SetMotion(callback); }}; - motion_devices->SetCallback(motion_callback); + motion_devices->SetCallback({ + .on_change = + [this](const Common::Input::CallbackStatus& callback) { SetMotion(callback); }, + }); } // Unique index for identifying touch device source @@ -78,9 +79,12 @@ void EmulatedConsole::ReloadInput() { if (!touch_device) { continue; } - Common::Input::InputCallback touch_callback{ - [this, index](Common::Input::CallbackStatus callback) { SetTouch(callback, index); }}; - touch_device->SetCallback(touch_callback); + touch_device->SetCallback({ + .on_change = + [this, index](const Common::Input::CallbackStatus& callback) { + SetTouch(callback, index); + }, + }); index++; } } @@ -127,7 +131,7 @@ void EmulatedConsole::SetMotionParam(Common::ParamPackage param) { ReloadInput(); } -void EmulatedConsole::SetMotion(Common::Input::CallbackStatus callback) { +void EmulatedConsole::SetMotion(const Common::Input::CallbackStatus& callback) { std::lock_guard lock{mutex}; auto& raw_status = console.motion_values.raw_status; auto& emulated = console.motion_values.emulated; @@ -162,8 +166,7 @@ void EmulatedConsole::SetMotion(Common::Input::CallbackStatus callback) { TriggerOnChange(ConsoleTriggerType::Motion); } -void EmulatedConsole::SetTouch(Common::Input::CallbackStatus callback, - [[maybe_unused]] std::size_t index) { +void EmulatedConsole::SetTouch(const Common::Input::CallbackStatus& callback, std::size_t index) { if (index >= console.touch_values.size()) { return; } -- cgit v1.2.3
