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.

Revert "Import experimental NS2 support and accumulated GPU fixes"

This reverts commit 535b676970. The Switch 2 support comes from the nx2 work instead, merged next.

Import experimental NS2 support and accumulated GPU fixes

2026-10-29T01:21:11+00:00

Bring the NS2 patch and local follow-up fixes onto Eglantine master. Includes native graphics services, instruction translation, syncpoint cancellation acknowledgement, texture handling and diagnostics. Experimental checkpoint; not ready to merge. The original Eden build passed, but this rebased branch has not been built or tested. Assisted-by: OpenAI Codex (implementation, debugging, tests and PR preparation)

[common] Switch to boost::unordered_flat containers (#4326)

2026-08-31T00:58:09+00:00

Replaces all instances of ankerl's unordered map/set with boost's `unordered_flat_*` classes. This uses std::hash since boost::hash is actually a lot slower. Also adds an abstraction layer in `Common` so future changes are quicker and easier. Other implementation details: - ankerl provided hash specializations for tuple and pair, so those were ported here - std::erase_if doesn't work on boost, so just used the ADL'd erase_if This should be about equal or superior performance as unordered_dense for everything except iteration.

[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

[*] change all std::unordered_map and std::unordered_set into ankerl::unordered_dense::map/set variants (#3442)

2026-02-10T02:34:07+00:00

mainly doing this to reduce memory footprint; we all know how nice ankerl::unordered_dense is in theory 4x faster - in practice these maps arent that "hot" anyways so not likely to have much perf gained i just want to reduce mem fragmentation to ease my porting process, plus it helps other platforms as well (ahem weak Mediatek devices) :) Signed-off-by: lizzie Co-authored-by: Caio Oliveira Reviewed-on: https://git.eden-emu.dev/eden-emu/eden/pulls/3442 Reviewed-by: DraVee Reviewed-by: CamilleLaVey Co-authored-by: lizzie Co-committed-by: lizzie

[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
