Merge nx2 into nx2-experimental

2026-11-02T13:43:01+00:00

Resolved by area: - audio feature_support.h: nx2's native revision handling. - fiber.cpp: ours, which also drops the unused rewind stack. - host_memory.cpp: ours granule bitmap and HintCold, plus nx2's fallocate hole punching per whole dirty granule on Linux. - texture_cache.h: nx2's old-age eviction pass, then our Collect(). - kepler_compute.cpp: shared upscale slots, then Fortune's Weave's, then the Kirby Air Riders scan. - nx2_gsv.h: ours, plus nx2's GetBufferMaxResolution and graphics device ids (1-based). - nvhost_ctrl_gpu.cpp: engine support flag bits 40-44. - lower_to_maxwell.h: ours as the base, with nx2's seven lowering commits applied one at a time. Second texture descriptor buffers are read bindless in TEX, TLD.SCR (level zero) and SUST; FSEL keeps its operand modifiers; TXD takes any channel mask. lower_to_maxwell.h lowers 837 Fortune's Weave and 1183 Mario Kart World shader dumps with the same rejects as nx2 and ours (12 and 0).

audio_core: accept the Switch 2 audio renderer revision

2026-11-01T19:58:49+00:00

Switch 2 titles send revision 16 with the 'REv' magic and use the voice crossfade fields. Without them GetWorkBufferSize failed with 0xc0299 and Fire Emblem: Fortune's Weave aborted (2153-1537). Ported from the Eden NS2 tree, keeping Eglantine's lenient revision compare.

audio: don't free an upsampler when cleaning up a circular buffer sink

2026-10-31T12:53:11+00:00

CircularBufferSinkInfo::CleanUp read its state as a DeviceState and freed DeviceState::upsampler_info. Only device sinks own an upsampler; a circular buffer sink's state starts with its buffer positions, so a game that changed or removed its circular buffer sink made the audio service free a pointer built from those positions and crash the emulator. Mario Tennis Fever does this during startup.

audio_core: accept audio renderer revision 16

2026-10-30T15:40:59+00:00

Switch 2 SDKs report audio renderer revision 16 ("REv@"; Mario Kart World's reports 15): Nintendo Switch Sports Resort's GetWorkBufferSize failed with InvalidRevision and the title aborted (2153-1537). Accept revision 16 and run it with revision 15's features, and log a rejected revision with its number.

Fix hang on emulation stop when audio renderer outlives its manager

2026-10-30T00:16:24+00:00

The Switch 2 aud:u client hands out an IAudioRendererManager the guest may close right after opening a renderer. The Manager was owned by value and renderers held a plain reference, so it was destroyed (stopping the system manager thread) while the renderer lived on. System::Stop() then waited forever on terminate_event, hanging shutdown. - Share ownership of the audio Manager with each IAudioRenderer - Bound the terminate_event wait in System::Stop() - Bound the emu thread wait in MainWindow::OnEmulationStopped() Co-Authored-By: Claude Sonnet 5.5

Switch 2: back GPU-only regions, pace presents, interleaved split methods

2026-10-28T02:28:10+00:00

- gpu 214 creates GPU-only memory the graphics server backs itself (title 4 renders everything into six 300 MB regions at 0x81_0000_0000). Back each with application-pool pages mapped into the alias code region and map that for the GPU. This is what made title 4's frames appear. - vi2 229 waits (bounded) for the presented frame's GPU fence: the reply reports every buffer free, so without this the game laps Eden's GPU thread and rewrites command memory it has not read yet. - Split methods: keep several parked methods keyed by resume address (NVN interleaves command buffers) and drop them when the submission ends. - hid 214 (per-frame vibration send) answered quietly. - Debug aids: EDEN_NX2_WINDOW_TRACE / EDEN_NX2_RT_TRACE (render targets, clears, textures), EDEN_NX2_AUDIO_LEVEL (output peak), EDEN_NX2_PB_DUMP (command list for offline replay), parsed-entry change check.

Switch 2: aud:u audio, REv revision tag, job-slot events, open-file limit

2026-10-27T21:21:19+00:00

- aud:u (nn::audio::CreateUserClientSessionByHipc) command 2 returns Eden's IAudioRendererManager; the renderer accepts Switch 2's 'REv?' update tag by comparing revision numbers. - nx2:gpu sub 211 signals the job slot in request word 17, not word 2; mapping jobs no longer stall once the SDK rotates slots. - eden-cli raises the CRT open-file limit (_setmaxstdio(8192)) like the Qt frontend, so loose RomFS folders don't run out of handles. - Per-mapping GPU logs moved to Debug.

[*] Remove Fix{Static,Small}VectorADL workaround for GCC 12 (#4386)
