From b92bf51ae1a08eca22bf0ce98b234692b9d59207 Mon Sep 17 00:00:00 2001 From: Morph <39850852+Morph1984@users.noreply.github.com> Date: Tue, 6 Oct 2020 05:08:52 -0400 Subject: hid: Implement GetVibrationDeviceInfo The first u32 describes the vibration device type which is a Linear Resonant Actuator used in Nintendo Switch controller hardware. The second u32 describes the vibration device position, in this case distinguishing between left and right vibration actuators. Pro Controllers have 2 LRAs each that can vibrate independently of each other, which means they have 2 distinct vibration device handles to distinguish between the two actuators. Similarly for joycons, the left joycon can be distinguished from the right joycon through the vibration device handle since each joycon has 1 LRA. --- src/core/hle/service/hid/hid.cpp | 26 +++++++++++++++++++++++--- src/core/hle/service/hid/hid.h | 16 ++++++++++++++++ 2 files changed, 39 insertions(+), 3 deletions(-) (limited to 'src/core/hle') diff --git a/src/core/hle/service/hid/hid.cpp b/src/core/hle/service/hid/hid.cpp index 86b83dcc6..993738f36 100644 --- a/src/core/hle/service/hid/hid.cpp +++ b/src/core/hle/service/hid/hid.cpp @@ -924,12 +924,32 @@ void Hid::GetActualVibrationValue(Kernel::HLERequestContext& ctx) { } void Hid::GetVibrationDeviceInfo(Kernel::HLERequestContext& ctx) { - LOG_DEBUG(Service_HID, "called"); + IPC::RequestParser rp{ctx}; + const auto vibration_device_handle{rp.PopRaw()}; + + VibrationDeviceInfo vibration_device_info; + + vibration_device_info.type = VibrationDeviceType::LinearResonantActuator; + + switch (vibration_device_handle.device_index) { + case Controller_NPad::DeviceIndex::Left: + vibration_device_info.position = VibrationDevicePosition::Left; + break; + case Controller_NPad::DeviceIndex::Right: + vibration_device_info.position = VibrationDevicePosition::Right; + break; + case Controller_NPad::DeviceIndex::None: + default: + vibration_device_info.position = VibrationDevicePosition::None; + break; + } + + LOG_DEBUG(Service_HID, "called, vibration_device_type={}, vibration_device_position={}", + vibration_device_info.type, vibration_device_info.position); IPC::ResponseBuilder rb{ctx, 4}; rb.Push(RESULT_SUCCESS); - rb.Push(1); - rb.Push(0); + rb.PushRaw(vibration_device_info); } void Hid::CreateActiveVibrationDeviceList(Kernel::HLERequestContext& ctx) { diff --git a/src/core/hle/service/hid/hid.h b/src/core/hle/service/hid/hid.h index fd0372b18..2f7483170 100644 --- a/src/core/hle/service/hid/hid.h +++ b/src/core/hle/service/hid/hid.h @@ -146,6 +146,22 @@ private: void SetIsPalmaAllConnectable(Kernel::HLERequestContext& ctx); void SetPalmaBoostMode(Kernel::HLERequestContext& ctx); + enum class VibrationDeviceType : u32 { + LinearResonantActuator = 1, + }; + + enum class VibrationDevicePosition : u32 { + None = 0, + Left = 1, + Right = 2, + }; + + struct VibrationDeviceInfo { + VibrationDeviceType type{}; + VibrationDevicePosition position{}; + }; + static_assert(sizeof(VibrationDeviceInfo) == 0x8, "VibrationDeviceInfo has incorrect size."); + std::shared_ptr applet_resource; Core::System& system; }; -- cgit v1.2.3
