One page, web/desktop.html, built stripped by web/build-demo.sh into
web/dist-demo. It opens two windows: an xterm running bash (X11 through the
in-page Xwayland) and a launcher drawn by the page. The base rootfs is 8.3 MB
of zstd for bash and xterm. Launcher items are tar.zst overlays
(tools/gexcc/debian/mkoverlay.py) unpacked into the running kernel, and apt
gets our pool as lazy files. Runtime .wasm ships as .wasm.zst
(web/src/zfetch.js). Measurements are in §9.1.
Shared code this changes, for every page:
- kernel: /proc lists every process (ProcTable info and snapshot through
the global kernel), and each has stat, status, statm, cmdline and comm. A
pty leaves FIONBIO and the close-on-exec ioctls to the kernel, which
fixes libuv (nvim) on a terminal.
- gex-wayland and the shims: wl_output.scale and set_buffer_scale.
Records carry the buffer and client scales; scale 1 behaves as before.
- compositor: a device-pixel output and decorations scaled by the page's
scale (1 unless a page passes one). Nearest sampling for 1:1 draws. The
client's cursor becomes the canvas's CSS cursor on every page (before,
only in direct present), and no cursor is composited. The present path
is unchanged: the worker's own WebGPU canvas, driven by its
requestAnimationFrame.
- runtime.js: wlScale; glLazy starts Mesa on the first guest GL request.
- web/build-all.sh: --x-only and --gl-only, for build-demo.sh.
Fixes from the first users, and the open xterm presentation report, are in
§9.2. tests/demo/desktop.mjs drives the demo. Its cursor and presentation
legs run unless DEMO_LEGS=0.
Squashed from demo/desktop (a6b38999 plus the driver commit) on master
e4c2a2c3. That branch's history also committed web/public/gex-apt (56
.debs of build output) by mistake, and this commit does not carry it.
