# Stage 30 - User-Space Window Manager (UWM) + Mouse Syscall
## Goal
- Add a minimal user-space desktop environment entrypoint.
- Provide a simple window manager demo (`uwm`) with focus, dragging, and rendering in framebuffer.
- Expose mouse snapshot data to user-space through a dedicated syscall.
## Implementation
- New syscall:
- Added `MOUSE_STATE` (`id=107`) in kernel/user syscall headers.
- Kernel side (`clks/kernel/runtime/syscall.c`) now exports mouse snapshot:
- fields: `x`, `y`, `buttons`, `packet_count`, `ready`.
- User wrapper added: `cleonos_sys_mouse_state()`.
- New user app:
- Added `cleonos/c/apps/uwm_main.c`.
- Features:
- Desktop background rendering.
- Multiple windows with z-order.
- Active window focus + border highlight.
- Drag by title bar (left mouse).
- Keyboard fallback controls (`Tab`, `W/A/S/D`, `Q/Esc`).
- Build integration:
- Added `uwm` into shell command app set in `cleonos/CMakeLists.txt`.
- Updated shell help text and standalone `help` app output.
- QEMU run/debug update:
- Added optional absolute pointer device by default:
- `-usb -device usb-tablet`
- New CMake option:
- `CLEONOS_QEMU_ENABLE_USB_TABLET=ON` (default).
## Acceptance Criteria
- `uwm` can be started from user shell.
- Framebuffer window demo draws multiple windows and supports dragging.
- Mouse state is retrievable from user-space via syscall `107`.
- `make run`/`make debug` use USB tablet by default for smoother pointer interaction.
## Build Targets
- `make userapps`
- `make iso`
- `make run`
## QEMU Command
- `make run`
## Debug Notes
- If `uwm` reports framebuffer unavailable:
- verify `FB_INFO` syscall is enabled and framebuffer bpp is `32`.
- If pointer behavior is relative/jumpy:
- keep `CLEONOS_QEMU_ENABLE_USB_TABLET=ON`.
- for manual QEMU invocation, include `-usb -device usb-tablet`.
- If mouse syscall returns `ready=0`:
- check boot log for PS/2 mouse init status under `[INFO][MOUSE]`.
