rs-dos/scripts/mksystem.sh, branch qemuSimple, kernel-only, 64bit OS, early stage.
https://git.2137697.xyz/rs-dos/atom?h=qemu2026-11-01T14:53:29Zscripts: rebuild the dev loop around build.sh/run.sh2026-11-01T14:53:29Zsalmoniksalmonik@tuta.io2026-11-01T14:53:29Zurn:sha1:7958276c9f0d230053520ba20f2a00f5ecda18e4
`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)2026-08-27T16:39:29Zsalmoniksalmonik@tuta.io2026-08-27T16:39:29Zurn:sha1:277218fe1ba1e3616bd147c9d9abecfc56b9957f
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.
image: single dd-able system.img replaces vvfat+data-disk pair2026-08-21T17:13:52Zsalmoniksalmonik@tuta.io2026-08-21T17:13:52Zurn:sha1:298528581d1a29032a1224600297316384d4e4f7
mksystem.sh stages one FAT32 image: \bzImage + \initramfs.cpio.gz
(rsbl paths), \EFI\BOOT\BOOTX64.EFI (kernel direct by default,
--chain for rsboot), \etc\motd.txt, empty \bin\cli + \bin\gui,
seed files at the root. --gpt wraps it in a partition table for real
USB dd targets.
Makefile: run/run-gui/debug attach only system.img on ide.0 (vvfat
lines deleted); stamp-based 'system' target rebuilds only when the
kernel is newer, so runtime writes survive reboots; system-fresh
wipes; inspect lists via mtools. build-image.sh/mkdisk.sh removed.
test-disk.sh boots system.img with a throwaway OVMF varstore — a
stale NvVars makes the firmware skip the \EFI\BOOT fallback.
sendkeys.py pacing 50ms->250ms/1.5s: keystroke loss under host load
corrupted typed lines (guest-side PS/2 ring overflow).
Gate: test-disk PASS (fsck clean, file survives poweroff).
