scripts: rebuild the dev loop around build.sh/run.sh

2026-11-01T14:53:29Z

`make` did not parse at all (missing separator at line 139), so every make target was dead. The folder also carried three overlapping launchers (boot.sh, qemu.sh, boot-image.sh) plus a fourth partial one in the Makefile, `cargo build --package rsdos` copy-pasted eight times, the QEMU invocation copy-pasted per script, and the test helpers (fail/wait_log/wait_qemu_exit/qemu_hmp) duplicated in five tests. New layout: - scripts/lib.sh: single config (image, OVMF, mem/smp), the one cargo invocation (build_all), the one QEMU shape (qemu_args), and the test harness (test_boot, wait_log, wait_qemu_exit, qemu_hmp, sendkeys) - scripts/build.sh: kernel + every bins/* in one pass - scripts/mksystem.sh: freshness-aware image build that now stages every bins/*.efi into /bin/cli|gui (they were never copied before) - scripts/run.sh: build + stage + boot in one command; --headless, --debug (GDB stub), --monitor (HMP socket), --fresh, --mem/--smp/ --bios/--image; on Wayland it auto-selects XWayland plus grab-on-hover so the mouse can be captured (Ctrl+Alt+G toggles) - scripts/tests/: the five automated tests on the shared harness - deleted: boot.sh, qemu.sh, boot-image.sh, lib-boot-args.sh, build-image-release.sh, build-bootloader.sh (rsboot chain dropped) The Makefile is now a thin wrapper: make run, make test, make system, make inspect, make help. Two-command flow: ./scripts/build.sh then ./scripts/run.sh (run.sh alone also works). Stale test assumptions fixed so the suite is green again: test-gfx waited for "gfx: check" while the shell prints "gfx check: PASS"; test-mouse/test-msg hardcoded msgrecv = task 3 (wm-input took slot 3 — ids are parsed from the log now); the queue-full probe targeted task 0, whose exec pump drains its own queue as completion codes (moved to the cursor task, which never recvs). Verified in QEMU: make test -> test-disk, test-gfx, test-mouse, test-msg, test-fault all PASS.

build: default profile is release (debug too slow for dev loop)

2026-08-27T16:39:29Z

Makefile: PROFILE=release, CARGO_FLAGS=--release; make release target kept as no-op (now default). boot.sh: PROFILE=release default; --debug flag opt-in. mksystem.sh: PROFILE=release default. test-disk/fault/gfx/mouse/msg: all use --release. All scripts syntax-checked.

scripts: migrate all QEMU/test scripts to single system image

2026-08-27T16:35:59Z

boot.sh: replace esp/ + DISK_IMG with single SYSTEM_IMG on ide.0 (hooks into mksystem.sh --force for auto-staging). boot-image.sh: delegate to mksystem.sh --chain (build-image.sh deleted). build-image-release.sh: delegate to mksystem.sh --chain --gpt. qemu.sh: flexible launcher uses SYSTEM_IMG; --chain flag for full-chain build. test-disk.sh: drop ESP_DIR (mksystem.sh stages everything). test-fault.sh: boot system.img on ide.0 + CRASHLOG stick on ide.1; replace deleted mkdisk.sh with inline mkfs.fat. test-gfx.sh: system.img on ide.0, stage via mksystem.sh. test-mouse.sh: system.img on ide.0, stage via mksystem.sh. test-msg.sh: system.img on ide.0, stage via mksystem.sh. Makefile: remove stale build-image.sh/mkdisk.sh references from help; image target delegates to mksystem.sh --chain. All scripts syntax-checked (bash -n). build-image.sh and mkdisk.sh no longer referenced anywhere.

rsnix v0.5.0: graphics layer + cursor compositor

2026-08-01T17:52:05Z

The first visible GUI surface: real rect primitives, a single shadow→display push path, and an on-screen mouse cursor that can never race the text surface. gop: - fill_rect + push_rect(x,y,w,h): every raster op rasterises into the RAM shadow, then push_rect copies the rect to the display (write-only, still never read) and composites the cursor on top. blit_glyph and scroll shifts now route through it. - cursor overlay: 12x16 pointer (const-fn built from column lists) drawn white with a black offset outline; position in one AtomicU64 (x:high 32, y:low 32) — unpack masks the low word (a bare 'as usize' cast is a no-op on 64-bit). The cursor never enters the shadow, so erasing is just a shadow push of the old rect. - cursor_redraw after scroll shifts and once at spawn (the vt diff never re-blits idle cells). cursor task (task 2, spawned at boot when a mouse is present): - owns the PS/2 ring; polls every 10 ms, moves the cursor (clamped), tracks buttons, and forwards every event to a task's queue when 'mouse ' armed it (the window-manager input path). - /dev/mouse is now a position device (x/y/buttons snapshot); 'mouse' watches the cursor live (prints on change); 'cursor' prints one-shot state; 'gfx' draws a status-bar demo; 'gfx check' is an in-kernel pixel self-test (shadow readback, display readback, cursor overlay purity) — PASS/FAIL per stage. Tests (headless QEMU + monitor injection): - make test-gfx (new): all four compositor checks PASS. - make test-mouse (rewritten): cursor tracks mouse_move deltas, buttons ride along, /dev/mouse snapshot, live watch, real-event queue routing. - make test-msg: task numbering shifted (cursor is task 2; msgrecv is task 3) — updated, still PASS. - make test-disk regression re-passes. 0 build warnings.

rsnix v0.4.0: GUI input foundation — PS/2 mouse + scheduler message queues

2026-08-01T17:34:40Z

Mouse (IRQ12, stream mode): ByteRing generalized for both PS/2 devices, ISR routes data-port bytes by the controller's aux bit; mouse_init with bounded-ACK handshake (boots without a mouse); packet decoder with bit-3 resync, screen-relative deltas, buttons. Exposed as /dev/mouse, the `mouse` stream command, and `make test-mouse`. Message queues (ADR 0003's GUI-era primitive): every task gets a static 16-slot TaskMsg ring; send/recv/recv_blocking with direct wake + tick scan safety net for the lost-wakeup race; `msgrecv`/`send` commands, `mouse ` routes real IRQ12 events into a task's queue, jobs shows q=. `make test-msg` + `make test-disk` regression pass.
