Simple, kernel-only, 64bit OS, early stage. https://git.2137697.xyz/rs-dos/atom?h=qemu 2026-11-01T15:33:09Z 2026-11-01T15:33:09Z salmonik salmonik@tuta.io 2026-11-01T15:33:09Z urn:sha1:363e24bcd18a28948f63fa78ac8a4eaa8784fe59 - test-usb boots an EHCI and an xHCI controller with a mouse + keyboard and asserts enumeration, report decoding, and input reaching the shell. The EHCI case asserts one key end-to-end (QEMU's EHCI model delivers only the first report through root-port split transactions); the xHCI case asserts a whole typed command. - lib.sh: qemu_args() already supplies -bios, so the fresh OVMF varstore copy was silently overridden by the system firmware. Pass the copy last (QEMU honours the last -bios) so tests really boot clean NVRAM. - DEBUG_NOTES: document why USB never worked on the OptiPlex (EHCI shipped with DEBUG_MATRIX enabled, no RMH/hub support, only the first controller, no boot protocol, unbounded DMA), the success/failure log to look for on hardware, and the QEMU coverage limits. - Makefile: add test-usb and include it in `make test`. 2026-11-01T14:53:29Z salmonik salmonik@tuta.io 2026-11-01T14:53:29Z urn: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.
