Red Bear OS

Add gamepad HID support following Linux 7.1 hid-input.c patterns:
Gamepad axes (GenericDesktop page 0x01):
- X (0x30), Y (0x31): stored in gamepad_axes[0..1]
(also still forwarded as mouse position for backward compat)
- Z (0x32), Rx (0x33), Ry (0x34), Rz (0x35):
stored in gamepad_axes[2..5] (triggers + right stick)
- Hat Switch (0x39): stored in hat_switch (i8)
Gamepad buttons (Button page 0x09):
- Extended from 3 to 32 buttons
- First 3 buttons still tracked as mouse buttons (backward compat)
- All button states tracked in gamepad_buttons (u32 bitmask)
State tracking:
- 6-axis array (gamepad_axes: [i32; 6])
- 32-button bitmask (gamepad_buttons: u32)
- D-pad hat switch (hat_switch: i8)
Cross-reference: Linux 7.1
- drivers/hid/hid-input.c: hidinput_configure_usage()
- map_abs(ABS_X|ABS_Y|ABS_Z|ABS_RX|ABS_RY|ABS_RZ|ABS_HAT0X)
- BTN_GAMEPAD / BTN_SOUTH / BTN_EAST / BTN_TR / BTN_TL
This means USB gamepads (Xbox, PlayStation, Switch Pro, generic HID)
will now produce axis and button events through ProducerHandle.
Base
Repository containing various system daemons, that are considered fundamental for the OS.
You can see what each component does in the following list:
- audiod : Daemon used to process the sound drivers audio
- bootstrap : First code that the kernel executes, responsible for spawning the init daemon
- daemon : Redox daemon library
- drivers
- init : Daemon used to start most system components and programs
- initfs : Filesystem with the necessary system components to run RedoxFS
- ipcd : Daemon used for inter-process communication
- logd : Daemon used to log system components and daemons
- netstack : Daemon used for networking
- ptyd : Daemon used for pseudo-terminal
- ramfs : RAM filesystem
- randd : Daemon used for random number generation
- zerod : Daemon used to discard all writes and fill read buffers with zero
How To Contribute
To learn how to contribute you need to read the following document:
If you want to contribute to drivers read its README
Development
To learn how to do development with these system components inside the Redox build system you need to read the Build System and Coding and Building pages.
How To Build
It is recommended to build this system component via the Redox build system, you can learn how to do it on the Building Redox page.
To build and test outside the build system, install redoxer then use check.sh script to build or test:
./check.sh- Check build for x86_64./check.sh --arch=ARCH- Check build for specific ARCH (aarch64,i586,riscv64gc)./check.sh --all- Check build for all ARCH./check.sh --test- Check the base system boots up on x86_64
You can also use make install to inspect the content on ./sysroot, or make test-gui to test booting with orbital interactively.
