Phase 4+5 of the device sim: - Display + touch verified end-to-end: virtio-gpu at 720x720 (fbdev emulation) renders the real WardenOS dashboard from the static LVGL fbdev+evdev UI build (flare-edge qemu-vm-support tools/build-ui-vm.sh); QMP input-send-event taps the Metrics tab and qemu/tests/ui-shot.sh asserts the repaint from screendumps. Two load-bearing QEMU flags found and documented: -global virtio-mmio.force-legacy=false (gpu/input are VERSION_1-only) and the 200ms press hold (an instantaneous press+release lands inside one LVGL indev poll and never clicks). - qemu/tests/qmp.py: minimal QMP client (screendump, tap, quit). - stage-2 init starts warden-ui when present and fb0 exists. - docs/decisions/0006-qemu-device-sim.md: virt-not-custom-board, the enters-at-kernel boundary, fragment policy, naming, consequences. - docs/architecture.md: new section 7 (device emulation), order-of-work item 7; modbus cross-reference to the bridge. - qemu/README.md: emulated-vs-not table, scenarios, gotchas, host/runner requirements. docs/ci-cd.md: runner needs one-time qemu-system-arm install (fail-closed smoke until then, [maintainer]-gated). Repo README updated. Final sweep on this commit: shellcheck clean, bridge 7/7 tests, boot smoke PASS, portal scenario PASS (check-in + fw pull + signed .wfw download), ui-shot PASS (touch navigates to Metrics) — all under the final flags.

# Launch the WardenOS device VM (qemu-system-arm -M virt, single Cortex-A7,

# 256M — the RV1106G3's shape). See qemu/README.md for what this does and does

# not emulate.

# Usage: run.sh --kernel <zImage> [options] [-- <extra qemu args>]
|
|
# --kernel PATH zImage (canonical or virt.fragment variant)
|
|
# --initrd PATH initramfs (default: qemu/out/initramfs.cpio.gz)
|
|
# --disk PATH virtio disk image from mkimage.sh (default: qemu/out/disk.img
|
|
# when present; pass --no-disk for a diskless initramfs boot)
|
|
# --no-disk boot without a disk (initramfs shell/smoke behavior)
|
|
# --slot _a|_b rootfs slot to boot (default _a)
|
|
# --rtc DATE guest RTC base, e.g. 2021-01-01 — reproduces the no-RTC
|
|
# "device boots believing 2021" incident class
|
|
# --rs485 SOCK unix socket chardev for the RS485/Modbus bridge
|
|
# (pci-serial: needs the virt.fragment kernel)
|
|
# --watchdog add i6300esb watchdog, reset on expiry (fragment kernel)
|
|
# --qmp SOCK QMP unix socket (screendump, input-send-event, quit)
|
|
# --display MODE off (default, -nographic) | on (gtk window) | headless
|
|
# (virtio-gpu without a window; screendump via --qmp)
|
|
# --ssh-port N hostfwd 127.0.0.1:N -> guest :22 (default 2222)
|
