Integrate batocera-extra features into batocera

[git-developer]

This issue has the purpose to track the progress of integration from batocera-extra into the batocera core. It is a living document that is updated when development progresses.

Open tasks

Prerequisites

• Mark dbus-python as installed
  • dbus-python is installed via buildroot; when pip doesn't know about it, it will try to install it requiring a build chain.
  • See patch
  • buildroot#500 and buildroot#511 were intended to solve this, but seem to have no effect
• Provide upower
  • See upowerd-start

Enable motion in emulators

• Add motion support to Cemu generator
  • See patch-cemu-generator-for-cemuhook
• Add motion support to Citra generator
  • See patch-citra-generator-for-cemuhook

Add cemuhook servers for popular controllers

Motion for devices with modern Linux drivers (e.g. Switch, DS4, DS5)

• Integrate motion_evdev
  • Install server in batocera
  • Start server on boot

Motion for Steam Deck

• Integrate motion_steam_deck
  • Install server in batocera
  • Start server on boot

  • e.g. /sys/class/hwmon/hwmon0/temp1_input in addition to /sys/devices/virtual/thermal/thermal_zone0/temp
  • thermal_zone is not available on some systems
• Allow flatpak emulators to use a Switch Pro Controller
  • #8283

cemuhook preparation

• Prevent citraGenerator.py from removing unknown settings
  • #8080

    Done in commit 9590272, pushed to master on 2022-10-03
  • Provide dbus-python
    • dbus-python is included
  • Provide upower (buildroot packages incl. upower were removed in d0e9d51, 2020-01-27) (moved to separate task)

joaorb64/joycond-cemuhook

Upstream: #71

• Consider hid-nx as module name
  • #74
• Create a mapping of controller names to a profile file
  • #77
• Avoid error on missing org.freedesktop.UPower
  • #72
• Provide an installable python package

Future options

(click to expand)

Touch control from remote devices (Smartphone / Tablet)

• remote_touchpad
  • Install flatpak package
  • Start server on boot
  • Show QR code in ES

Additional emuhook servers

• motion_remote for e.g. Smartphones (requires user configuration)
• motion_steam_controller (supports both motion and touch)
• motion_wiimote

BR2_PACKAGE_UPOWER is just a package to enable as a dependancy where needed

That's good to know. I hoped so but didn't look it up yet, so thanks for the confirmation.

To keep things sorted, I won't create a PR for this until we have an overall strategy for the integration of joycond-cemuhook, though. BTW, I opened a thread on Discord.
