enricobuehlerandClaude Fable 5	e0e845b7df	fix(encode/pyrowave): pin the NT-handle import contract to consume-on-success-only ... import_plane closed the shared NT handle on every pyrowave_image_create failure, believing pyrowave only consumes it on success. The vendored truth was messier: Granite's allocator closed by-reference handles UNCONDITIONALLY after the first vkAllocateMemory — success AND failure — while failures before the allocator (validation, vkCreateImage, no memory type) left the handle open, and both classes surface as the same error code. So the call site could not know whether to close, and an allocate-stage failure double-closed a possibly-recycled handle value (audit WP5.3). The filed fix (DuplicateHandle + close the original unconditionally) traded the double close for a guaranteed leak on every pre-allocate failure and left the ambiguity in place. Patch 0006 fixes the callee instead: the allocator never closes a caller's handle, and pyrowave_image_create consumes it exactly at its success return — which is what pyrowave.h ("take ownership and close the HANDLE on import") documents, and what Granite's semaphore import already did, so import_fence was correct as written and the two paths now share one contract. The close-on-failure in import_plane is thereby correct on EVERY path, including a vkBindImageMemory failure after a successful allocate. Bonus fix recorded in the patch: the allocator's block-recycling retry loop used to re-run vkAllocateMemory with import_info still pointing at the just-closed handle. Both-platform gates green; pyrowave_win_smoke (.173, 34/34) re-validates the live import path against the rebuilt vendored C++.

enricobuehlerandClaude Fable 5	ac0e73321c	perf(pyrowave): elevated GPU scheduling + global-priority encode queue ... PyroWave's wavelet encode runs on the GPU's compute/shader cores, so a GPU-bound game starves it: submit spikes from ~2 ms to ~15 ms under a 95%+ game load and the stream fps collapses. NVENC is immune (separate encoder ASIC). Two levers to let the encode get scheduled ahead of the game's rendering: - Windows process GPU scheduling: D3DKMTSetProcessSchedulingPriorityClass, env PUNKTFUNK_GPU_PRIORITY = off|above-normal|high (default)|realtime. Best-effort, once per process, non-fatal on refusal (enc/windows/pyrowave.rs). - Global-priority Vulkan encode queue (Granite patch 0005): request a VK_KHR_global_priority queue (PYROWAVE_QUEUE_PRIORITY = off|high|realtime, default realtime), downgrading REALTIME→HIGH→none on NOT_PERMITTED so a refused class never regresses the encoder to HEVC. HONEST STATUS: on an RTX 4090 / Windows / WDDM neither moved the ~15 ms spikes — the graphics-vs-compute preemption granularity is the wall, not the priority level. Kept because both are correct, harmless (graceful fallback), and may help other GPUs/drivers. For a GPU-saturated game the working levers are reducing the encode's GPU cost (4:2:0/8-bit) or H.265; PyroWave holds full rate on the desktop and in games that leave the GPU headroom.

enricobuehlerandClaude Fable 5	4c3b11445c	feat(host): vendor PyroWave + minimal Granite subset as crates/pyrowave-sys ... Phase 0 of design/pyrowave-codec-plan.md — the opt-in wired-LAN ultra-low- latency codec. Vendored at upstream 509e4f88 (API 0.4.0, Granite 44362775, volk + vulkan-headers pins in PUNKTFUNK-VENDOR.txt), pruned to the 6.6 MB the standalone no-renderer build needs; scripts/vendor-pyrowave.sh reproduces the tree (a pin bump is protocol-affecting, plan §4.2). build.rs drives the wrapper CMakeLists (static archives incl. a static C-API lib upstream only ships shared) + bindgen over pyrowave.h; Linux and Windows only, empty stub elsewhere (Apple gets a native Metal port, §4.7). Offline-safe by construction: no network, no system lib, vendored Vulkan headers — same model as the opus dep (flatpak builder has no network). Phase-0 validation on .21 (RTX 5070 Ti, driver 610.43.03): - upstream pyrowave-c-test + interop test (incl. dmabuf/DRM-modifier Vulkan<->Vulkan) pass, from the pristine AND the pruned tree - GPU kernel times at ~1.6 bpp noise: encode/decode 0.090/0.042 ms @800p, 0.146/0.067 @1080p, 0.226/0.103 @1440p, 0.477/0.201 @4K — order of magnitude under NVENC's 1-2 ms retrieve, CBR lands within ~100 B of target - cargo test -p pyrowave-sys green (static link + API-version pin check) Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>	2026-07-15 00:35:10 +02:00
