app, config, ctrl, motion: CemuHookUDP support (SteamDeckGyroDSU support on Steam Deck)

[popsUlfr]

Hi,

This pull requests adds basic CemuHookUDP protocol support to enable gyro input and is supposed to be used in conjunction with https://github.com/kmicki/SteamDeckGyroDSU on the Steam Deck.
The source files udp_client.h, udp_client.cpp, udp_protocol.h, udp_protocol.cpp were taken from the yuzu project and modified and simplified to better integrate with the Vita3K codebase.

Here's a video of the working gyro in Gravity Rush, I raised the default sensitivity a bit since filming this:

There are two new configuration options:

• cemuhookudp-address: expects an address in the form of 127.0.0.1:26760
• cemuhookudp-gyro-scale-divider: modifies the gyro sensitivity. The calculation is done like this: gyro.x/y/z * (1.0 / cemuhookudp-gyro-scale-divider). So the higher the value the lower the sensitivity and the lower the. value the higher the sensitivity. The default is 39. A value of 1 maps gyro input 1:1.

They are not configurable through the interface yet but exist in the configuration file.

So in effect to get Vita3K with working gyro on the Steam Deck:

1. Install SteamDeckGyroDSU: https://github.com/kmicki/SteamDeckGyroDSU (EmuDeck has an option to install it in its interface if you are already using it)
2. Apply this pull request and compile Vita3K.
3. In Steam Input set Touchscreen Native Support to always on for multi-touch support.

In the controller interface if the SteamDeckGyroDSU server has replied to the CemuHookUDP client, motion support will be marked as such:

I hopefully fixed the CI building for windows and macos builds.

Thank you very much for this PR, I believe if/when we migrate to SDL3 it won't be needed anymore.

Ah, so SDL3 can expose the Steam Deck's gyro directly ? Looking at the discussion here libsdl-org/SDL#9148 it seems that one would still need to manually query the gyro values.

DSU is helpful for a lot of non-SDL gyro stuff, not just Steam Deck. Wiimotes, JoyCons, and I believe even some VR Controllers. It's definitely very nice to have as an option. I'm not sure if SDL3 plans to support any or all of these in a verbose manner, but again, very nice to have.

If now more boost modules are used, then this modules should be added into BOOST_MODULES_TO_FIND in main CMakeLists.txt
It used for windows compilation without vcpkg

Ok, thank you, I'll add them there.

EDIT: I think asio and crc are already part of the system cmake boost component but please correct me if I'm wrong.

Cmake is missing some boost components. That's not really an issue (if you don't have the asio or crc component you'll always get an error at some point). However, the fallback repository https://github.com/Vita3K/ext-boost does not have boost crc. It needs to be updated before this PR is merged or Vita3K will break for people not having an existing boost library availble (@Zangetsu38 )

[popsUlfr]

@Macdu Should I try to submit a pull request to the https://github.com/Vita3K/ext-boost repo to get the crc module in ?

[Macdu]

Yes you can (except if @Zangetsu38 wants to do it first), that's the only thing preventing this PR from being merged.

oh, i have not see sory, i can yes 🆗
