core: use the 12 GiB layout and auto-stub IPC for Switch 2 titles

2026-10-29T07:40:34+00:00

Switch 2 titles size their heap from the total memory and stop at the first unimplemented command, so they only booted with the 12 GiB layout and EDEN_NX2_AUTO_STUB set by hand. Detect them from main.npdm before the kernel starts and apply the layout as a per-game value (the configured layout comes back once the game is closed), and auto-stub unknown commands from Switch 2 processes.

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.

Error was suggesting it was not available for connection although i saw it booting on logs. Debugged and noticed signal_pipe_ was not the correct one, and followed the example of client_socket_. GDB stub is now working, on windows, at least. Reviewed-on: https://git.eden-emu.dev/eden-emu/eden/pulls/4339 Reviewed-by: Lizzie and Samuel Reviewed-by: MaranBr

[hle] support passing arguments to homebrew applications (#4013)

2026-06-15T01:02:33+00:00

Homebrew (.NRO) program args support Adds a 'program_args' setting and delivers it to NRO homebrews via libnx's homebrew ABI. NROs previously had no way to receive CLI flags (e.g. NZ:P's -noglsl). Setting: program_args, Category::System, startup-only. Surfaced in Qt + Android Debug sections. NRO loader: builds a 4-entry 'ConfigEntry' table + argv at the data segment tail; prepends 'homebrew ' so user args land at argv[1]; scans for 'svc #7' to use as LR. Drops the stale NSO-style argdata append. KProcess: stores loader-provided guest addresses; 'Run' switches to the homebrew entry (x0=config_ptr, x1=-1, lr=svc7) and patches the real MainThreadHandle into the ConfigEntry slot. Legacy NSO path unchanged. Tested on NZP — args reach 'argv' correctly. Reviewed-on: https://git.eden-emu.dev/eden-emu/eden/pulls/4013 Reviewed-by: Lizzie Reviewed-by: MaranBr

[common, core] remove uneeded memory indirection overhead at startup (#3306)

2026-01-16T22:39:16+00:00

for core stuff: just remove unique ptrs that dont need any pointer stability at all (afterall its an allocation within an allocation so yeah) for fibers: Main reasoning behind this is because virtualBuffer<> is stupidly fucking expensive and it also clutters my fstat view ALSO mmap is a syscall, syscalls are bad for performance or whatever ALSO std::vector<> is better suited for handling this kind of "fixed size thing where its like big but not THAT big" (512 KiB isn't going to kill your memory usage for each fiber...) for core.cpp stuff - inlines stuff into std::optional<> as opposed to std::unique_ptr<> (because yknow, we are making the Impl from an unique_ptr, allocating within an allocation is unnecessary) - reorganizes the structures a bit so padding doesnt screw us up (it's not perfect but eh saves a measly 44 bytes) - removes unused/dead code - uses std::vector<> instead of std::deque<> no perf impact expected, maybe some initialisation boost but very minimal impact nonethless lto gets rid of most calls anyways - the heavy issue is with shared_ptr and the cache coherency from the atomics... but i clumped them together because well, they kinda do not suffer from cache coherency - hopefully not a mistake this balloons the size of Impl to about 1.67 MB - which is fine because we throw it in the stack anyways REST OF INTERFACES: most of them ballooned in size as well, but overhead is ok since its an allocation within an alloc, no stack is used (when it comes to storing these i mean) Signed-off-by: lizzie lizzie@eden-emu.dev Reviewed-on: https://git.eden-emu.dev/eden-emu/eden/pulls/3306 Reviewed-by: CamilleLaVey Reviewed-by: MaranBr Co-authored-by: lizzie Co-committed-by: lizzie
