    v0.3.8 Stable

    intpa released this 2026-10-14 06:36:04 -04:00 | 213 commits to main since this release

    0.3.8 — ImGui backend from the Forgejo fork, trimmed

    The embedded ImGui backend is now built from the fork intpa/imgui-smash (branch deluxe, commit 7f0e47c): upstream Coolsonickirby/imgui-smash bb47b205 plus the renderer correction that used to be a local patch, with the Dear ImGui demo and metrics windows, the debug tools and two unused default fonts removed. The displayed font (JetBrains Mono NL) and the ig* ABI are unchanged, so the overlay looks the same and still borrows a standalone libimgui_smash.nro when one is present.

    Deluxe's own code is unchanged. patches/imgui-smash/archive-pin.json now points at the fork and applies no patch; tools/prepare_imgui.py treats the patch step as optional.

    Standalone companion. The same fork commit builds the standalone backend plugin: libimgui_smash.nro 888,832 B (was 1,282,048), SHA-256 a3f794b2d2af15d5f2c2868f22e81c865702524160640864604731b7afe6775d, identical export set, 1.92.7 WIP (19263) tag and text_offset == 0. It is not a release asset here; it ships from the fork.

    Eden acceptance (2026-10-14): external host (trimmed standalone + Elite Legal Stages), embedded host, and reversed load order all render Deluxe's Debug and settings views and Elite's stage list cleanly at 60 fps with no asserts. Evidence in the tangent directory imgui-fork-1014/eden-test/.

    0.3.7 — runtime footprint trims

    What the plugin holds while the game runs, after a symbol-level pass over the 0.3.6 ELF:

    • Diagnostics thread stack 2 MiB → 256 KiB. The Switch std gives every Rust thread a 2 MiB stack from the game heap unless the spawner sets one; Deluxe never did. About 1.75 MiB of heap back for the whole run. Hardware check: heartbeats keep arriving in hang-trace.log, no crash report naming deluxe-diagnostics.
    • Pia RTT station table allocated on first use. The 107 KB table (253 stations × 100-sample ring) lived in .data; it is now allocated by the diagnostics poll after the first RTT sample of the process and never exists offline. Until it exists the overlay shows exactly what an empty table shows (tested).
    • API trace chunks 4096 → 2048 rows (80 KiB .bss); still ~1.9 s per chunk at the measured hardware rate against the 500 ms drain.
    • Callback capture buffer (64 KiB) allocated per capture and freed after export; the render path still never allocates.

    Sections .text 1402336 / .rodata 343120 / .data 69912 / .bss 138672; resident image 1.95 MB (0.3.6: 2.21 MB). With the stack the steady-state cost drops by about 2.0 MB.

    Not in this release: the embedded imgui backend trims, which are being prepared in the fork intpa/imgui-smash for both the embedded archive and the standalone companion plugin.

    v0.3.6 - kernel memory probe in the hang trace and Debug view Stable

    intpa released this 2026-10-13 19:54:54 -04:00 | 220 commits to main since this release

    Kernel memory probe. Every hang-trace heartbeat now carries mem_used, mem_total, mem_free and heap_region in bytes from svcGetInfo on the game process (TotalMemorySize, UsedMemorySize, HeapRegionSize), refreshed every 500 ms by the diagnostics thread and shown as a Memory row in the Debug view's Performance table. No hook changed; the UI path makes no system call. The same call works under Eden, so console and emulator headroom compare directly.

    v0.3.5 - streamed API trace, opt-level s Stable

    intpa released this 2026-10-13 18:32:04 -04:00 | 223 commits to main since this release

    The API trace no longer holds a capture in memory. Rows are packed to 20 bytes and streamed: hooks fill one of two 4096-row chunks (160 KiB in .bss, the whole resident cost) while the diagnostics thread drains the other into the open api-.csv every 500 ms. Nothing is copied at the end. Capture length is bounded by the 30 s duration, not by capacity; rows that arrive while both chunks are full are counted in skipped.

    CSV: header written when the capture arms; engine, reason, skipped and event_count move to the footer before "# complete=1". tools/analyze_render_trace.py reads metadata anywhere and is unchanged.

    Release profile opt-level = "s": .text 1590896 -> 1401296 B. Idle resident image 2.21 MB (0.3.2: 3.99 MB); a running capture adds about 190 KB where 0.3.3/0.3.4 added 2 MiB plus a 2 MiB copy at export.

    v0.3.4 - capture allocation is fallible Stable

    Follow-up to 0.3.3: the per-capture API trace allocation is now fallible. Arming a timing or CSS capture on a game heap that cannot spare 2 MiB is refused and reported as "timing capture could not be armed" instead of aborting the game. Nothing else changed; resident footprint stays 2.23 MB.

    v0.3.3 - API trace buffer allocated per capture Stable

    intpa released this 2026-10-13 17:41:25 -04:00 | 230 commits to main since this release

    Resident footprint 3.99 MB -> 2.23 MB. 0.3.1 kept the 65536-event API trace in .bss; 0.3.3 allocates it on the diagnostics thread when a timing/CSS capture is armed and frees it after the CSV export. No capture, hook, flag or overlay row changed.

    Context: 2026-10-13 evening console boots (0.3.2 + Training Modpack r31 + the OBS companion's trace build) failed before the title with null-pointer faults in unrelated game threads and no plugin frame on any stack, the pattern of a game heap the loaded plugin set has outgrown. This release removes Deluxe's 1.9 MB share of that growth. Not yet run on hardware.

    Always-on hang-trace.log for loading-screen freezes: a 5 s heartbeat of this plugin's hook call counts (present, backoff idle pass and sleep, the three CAPTURE_CSS hooks, common-module load/unload, per-fighter tick, cut-in) marking any hook that entered and never returned as ACTIVE with its age, plus first-firing and scene-change lines stamped by system tick. Requested by the Training Modpack freeze investigation. No behaviour change.

    v0.3.1 character-select capture and backoff gate Stable

    intpa released this 2026-10-12 22:41:36 -04:00 | 238 commits to main since this release

    Character-select capture and backoff eligibility gate.

    • Dispatcher backoff now sleeps only after a scene hook has fired and while the tracked window presented within the last 250 ms; the Performance row reads Armed until then (install log code 102 a=5 marks the first pass). Boot, the logo/movie/title sequence and a stalled renderer run the game's original loop.
    • Opt-in CAPTURE_CSS boot flag (empty file in sd:/ultimate/ssbu_online_deluxe_rewrite/): three read-only hooks (dispatcher registration 0x3549720, dependency wait 0x354ccd0, UI job 0x375e260) and an automatic 30 s capture on each character-select entry. Keep the hand still for ten seconds, then move it for twenty. New api-<tick>.csv rows: 60/61 per-frame actual backoff sleep totals, 62/63 read-only thread priority and core mask, 64 UI dispatch, 66 dependency waits, 77 UI job span. Nothing is set or reordered. Without the flag these hooks do not exist.
    • Manual L+R+Up capture lasts 30 s; the API trace holds 65536 events in .bss, so the NRO is smaller than 0.3.0.
    • tools/analyze_render_trace.py reports a css_capture section.

    v0.3.0 dispatcher idle backoff Stable

    intpa released this 2026-10-12 15:59:32 -04:00 | 240 commits to main since this release

    Dispatcher idle backoff: the character-select slowdown fix, applied to all profiles and scenes.

    Root cause (Astra xhigh trace): the game's task dispatcher (main+0x354a6d0) busy-polls six empty job queues while the main thread waits ~4.8 ms per CSS frame on one nn::ui2d::Layout animation job (main+0x375e260, worker 1); in a match the same wait is ~0.9 ms. The two-image LessLag ring cannot hide the resulting variance. This release adds one inline hook at main+0x354ab48 that lets MainThread sleep briefly (5 us doubling to 50 us after 16 spinning passes) only when every queue is empty, every pending counter is still non-zero and no fiber is ready to resume. No job, counter, lock or ordering changes. Performance view gains a "Backoff" row; DISABLE_BACKOFF flag and dispatcher_backoff.ini tunables documented in README.

    Eden production A/B/A (175% CPU quota): CSS LessLag 55.6 -> 60.0 -> 54.2 fps (off/on/off) at 26.6 -> 19.5 -> 26.8 CPU ms/frame; Vanilla 60.0; live match 59.8 fps at 16.3 CPU ms/frame; unlimited 60. Installed on the Switch 2026-10-12 19:58Z; hardware observation pending (docs/VALIDATION.md).

    Standalone version: https://git.syntaxbyexample.com/intpa/ssbu-dispatcher-backoff (one owner per hook site; do not stack both).

    v0.2.1 deferred persistence on PENDING Stable

    v0.2.1: defer host persistence until a pending plugin change is applied

    Pinned reference for plugin consumers. Crates at this tag: deluxe-plugin-abi
    2.0.0, deluxe-plugin-sdk 2.0.0 (unchanged from v0.2.0); host crate 0.2.1.
    Change versus v0.2.0: a REQUEST_PENDING answer no longer writes the plugin
    INI; the host persists when it observes current(option) equal to the pending
    choice (checked every overlay draw, page hidden or not) or when a later
    request on that option returns REQUEST_APPLIED; stepping a pending change
    back to the live value cancels it and writes nothing. APPLIED unchanged.
