game_list: discover loose dumps without walking their RomFS payloads

2026-11-01T20:52:30+00:00

Defer RomFS construction, reuse one discovery result, omit recursive folder sizing, and release rows discarded by cancellation. Add scan suspension and regression coverage for extracted layouts and Unicode paths. Assisted-by: Codex (implementation, selective integration and automated validation)

debugger: monitor handles lists each handle's type and service event name

2026-10-28T16:31:45+00:00

gdbrsp.py gains raw and monitor commands.

nx2: notes on the recurring worker-thread crash; gdbrsp waits without a timeout

nx2: read debug switches once; key scripts from a file

2026-10-28T11:47:45+00:00

Several debug switches were read with std::getenv on every macro call, QMD, semaphore write or draw. The UCRT getenv locks and scans the environment, thousands of times a frame; a long EDEN_NX2_KEY_SCRIPT made title 4 crawl at 2 fps. Each is now read once. EDEN_NX2_KEY_SCRIPT=@ reads the script from a file. gdbrsp.py gains 'hits' (log registers, frame chain and object words at breakpoints, following the stopped thread).

Switch 2: native memory/images, GPU-accessible attribute, TSG subcontexts, syncpoint shim

2026-10-27T23:30:20+00:00

- gsv 111/112/114/423/429/430/314/315/435 track native memory and images with real ids (meanings from changes.patch); 1510/435 use its block-linear layout. - svc 0x80 sets a real GpuAccessible (0x20) memory attribute (from changes.patch). - Characteristics report TSG subcontexts (flag 22, 64 per TSG at 0xb4); NvRm otherwise allows one subcontext and a second NVN queue fails its setup. - Syncpoint shim: flag 26, address-space ioctl 0xB, and GPU reads of the shim page return guest syncpoint values (scheme from changes.patch). - EDEN_NX2_IPC_TRACE also logs TIPC commands; gdbrsp.py watch/mem improvements.

Switch 2 GPU memory handles and mappings at requested addresses

2026-10-27T21:39:54+00:00

nx2:gpu 101 (CreateGpuAccessibleMemory) returns real GpuMemoryHandles; 211 (NormalMapGpuMemory4K) maps handle+offset at the requested GPU address, including sparse regions, through Nx2GpuMemoryRegistry::MapAt (SMMU ranges are reused). 102/213/214 complete through their job-slot events. gdbrsp.py waits for a real thread before driving the stub and gains a write-watch op. Notes record the current stop: an NVN command buffer with no command memory.

Switch 2: window image sizes, queue semaphores, built-in fonts, memory budget

2026-10-27T21:04:06+00:00

- gsv 1510 CalculateRequirements: block-linear size/alignment for window images. - nvhost-gpu: Switch 2 channel event 7 is a real (unsignalled) event. - Puller mirrors NVN2 queue semaphore releases into the page the CPU and GPU wait on (the first two-page nx2:gpu region); EDEN_NX2_METHOD_TRACE logs methods. - pl:u 2000/2010 GetBuiltInFontSharedMemory/GetBuiltInFontData serve plain TTF copies of the shared fonts. - Switch 2 processes count the alias region in their max memory, so the game's nninitStartup heap (total - 6.3 GiB) has room for its sound heap. - gdbrsp.py: interrupt, threads, selthread, hits, continue_async, sleep.

nvdrv: Switch 2 GetEngineInfo, TSG flag, Ampere object classes, channel ioctl passthrough

2026-10-27T19:54:37+00:00

Once an nx2 NvRm identifies itself (0xD0-byte characteristics), nvhost-gpu and nvhost-ctrl-gpu answer unknown ioctls with a logged input echo instead of NotImplemented, ctrl-gpu reports GR + async-copy engines, and Ampere class numbers (and class 0) map onto Eden's Maxwell object slots. gdbrsp.py gains trace/flow/ breakwhen/fp helpers.

nvdrv: Switch 2 GPU address-space layout; gpu 33/203

2026-10-27T18:57:51+00:00

- AllocAsEx from Switch 2 NvRm passes flags 5, no big page size, range [0x8000000, 0xC000000000) and split 0 (small pages only). Treat split 0 as small pages up to the end, keep a 4 GiB big-page region after it, and give that allocator an absolute limit (Eden's length-as-limit breaks once the split is past the region length). - gpu TIPC 33 returns a count, 203 a kind plus a VA range used by nn::gpu::sdk::CreateGpuAddressSpace. - gdbrsp.py: unbreak, step, breaklr, unbreakpc, fp (frame walk), trace.
