83809bbe94 feat(userspace): programs in /bin w/o .elf; bin manifests (needs = display) so shell runs snake; Ctrl+C kills foreground via terminal interrupt notification; ctrl keys; sleep 2026-10-27 21:16:00 +01:00
4030dd4315 feat(adapter): init+storage packed into kernel image; drop adapter FAT16 reader + virtio-blk 2026-10-27 16:58:11 +01:00

b4390b7b6d refactor(userspace): split syscall/fat16/ext4 by concern; trim comments 2026-10-27 13:21:53 +01:00
694c675a40 feat: devices via caps (BootInfo, init assigns devices, drivers map MMIO/DMA themselves, IRQ-driven input); drop boot device wiring and info pages; headless display fallback 2026-10-27 12:28:39 +01:00
2792387348 fix: VirtIO keyboard input latency and direction accuracy
- Driver now drains SYN/repeat/unknown events in a loop instead of
  returning None on the first non-key event
- Snake drains all pending input events per tick, applies only the
  latest direction change (prevents stale event accumulation)

0a47b5489a feat: VirtIO keyboard input for QEMU GUI
- Add VirtIO input device driver (device ID 18) reading from eventq
- Translate Linux keycodes (WASD, arrows) to InputEvent
- Kernel probes for VirtIO input device, falls back to UART
- Add -device virtio-keyboard-device to run-gui Makefile target
- input-qemu tries VirtIO first, falls back to UART

27be73f42d feat: wire display + input servers to snake, fix QEMU 11.x GPU bug
VirtIO GPU: QEMU 11.x has RESOURCE_ATTACH_BACKING (0x0104) and
RESOURCE_FLUSH (0x0106) command types swapped in its legacy MMIO
VirtIO GPU implementation. Workaround: send swapped type values.
Confirmed via QEMU monitor (xp shows correct bytes in memory)
and QEMU trace events (device dispatches to wrong handler).

Display pipeline now works end-to-end:
  adapter → GPU init → create_2d → attach_backing → set_scanout
  display-server → clear(blue) → flush → transfer + resource_flush
  snake → draw commands via IPC → display renders → flush to GPU

Input server:
  - New driver-input-uart crate (reads UART at mapped VA 0x20000)
  - New bins/input-qemu composition root
  - Adapter loads input-server, maps UART MMIO into its address space
  - Init delegates both display_ep (slot 0) and input_ep (slot 1) to snake
  - WASD keys → UART → input-server → IPC → snake direction change

Snake game runs with display and input, exits on wall collision.
