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.

fix pi-lens warnings: unwraps, shell SC2046, dup code (fmtbuf/scripts/hexdump/cat/ahci/pci)

2026-08-01T16:25:55Z

- memory.rs: self-test Layout::from_size_align no longer panics — the test fails cleanly on an invalid layout - fat.rs: v() no longer unwraps the active-volume slot — invariant violation logs + halts instead of panicking mid-disk-io - strbuf: shared FmtBuf replaces the duplicated PanicBuf/FmtBuf (main.rs + sched.rs) - test-disk.sh: SC2046 — conditional --fresh arg no longer relies on word splitting - scripts: boot.sh/boot-image.sh share lib-boot-args.sh (dup args loop) - shell: cat/hexdump stdin pairs unified with Option<&str> marker; hexdump format_row folded into format_partial - ahci: read/write_sectors unified behind dma_sectors - pci: config_read/write share config_addr

scripts: automate the data-disk workflow (mkdisk / sendkeys / test-disk)

2026-07-31T23:56:12Z

- scripts/mkdisk.sh: create the FAT32 disk with mkfs.fat -C (the flag that actually creates the file — plain mkfs.fat fails on a missing path), accept M/G/K sizes, seed seed/ files via mtools; --fresh re-formats, --no-seed skips seeding - scripts/sendkeys.py: type lines into the guest via the QEMU monitor (US layout). Punctuation must use QEMU's named keys (minus, slash, dot, ...) — bare '-', '.', '/' are not valid sendkey names, and '-' is the modifier separator, so they were silently dropped before - scripts/test-disk.sh: full automated round trip — build, deploy, ensure image, boot headless QEMU, drive the shell (ls /disk, mkdir, echo >, cat, poweroff), then verify with fsck.fat (must be clean) and mtype (file content must have survived poweroff) - Makefile: make disk / disk-fresh / inspect / test-disk; run, run-gui and debug now auto-create a missing DISK_IMG; fix the stale comment (mkfs.fat without -C) - scripts/boot.sh: auto-create a missing DISK_IMG via mkdisk.sh - seed/: motd.txt + lines.txt seeded onto fresh images - Verified end to end: ./scripts/test-disk.sh --fresh passes

ahci: scan all ports; fat: mount first valid FAT32 disk

2026-07-31T19:29:49Z

The kernel previously started only AHCI port 0, so any launch where the firmware/QEMU put something else on port 0 (e.g. the ESP from an implicit -drive file=fat:rw:esp) left the real disk unnoticed: 'unsupported sector size 0' and no mount. - ahci.rs: enumerate CAP.NP/PI ports, start every port that links up (empty ports settle at DET=0 and are skipped quickly), keep up to 8 disks, and expose disk_count()/select() for the filesystem - fat.rs: try each disk in port order and mount the first valid FAT32 volume; non-FAT disks are logged and skipped - scripts/boot.sh: attach the data disk on ide.0 and the ESP on ide.1 (DISK_IMG env var, default /tmp/disk.img), matching the Makefile - Verified with the disk on port 0 (Makefile style), port 5 (old-style command line), and with the ESP on port 0; fsck.fat stays clean
