* Performance diagnostics and small wins for title 1Takoroka6 days1-1/+18
| | | | | | | | | | | | | | | | | | - eden-cli: SDL called SDL_AppIterate back to back, keeping a host core at 100% polling input; run the main callbacks at 240 Hz. - EDEN_NX2_IDLE_SPIN_US: optional spin before an idle core blocks (measured: no gain on title 1, so off by default). - EDEN_NX2_SVC_TRACE=<first>:<last>: trace SVCs (with thread ids) for a range of presents only. - MME DMA reads flush GPU-written memory first (never triggered on title 1, kept for correctness); render-enable override histogram instead of the first-400 log. Measured on title 1's title screen (RTX 4070 Laptop): GPU ~20% busy, the six emulated cores ~0.9 host cores in total, Eden's GPU thread 45-70% busy and largely waiting: on host fences for semaphore acquires (GPU accuracy High delays every release to host completion), on ASTC upload Finish(), and in a 1 ms poll sleep. gpu_accuracy=Low: ~12.5 -> ~16 fps.

* [core/arm] introduce vtable bouncing (#2943)lizzie2025-11-031-1/+15
| | | | | | | | | | | | | | Basically this just makes functions that go into zero-page or invalid addresses "bounce" back (with a return err of 0) such that it emulates a subroutine returning appropriatedly... this is mainly inspired by [this particular commit](https://git.citron-emu.org/Citron/Emulator/commit/fbb4f5c015d778ed0c8e2d91b01dcdffd7da9681); with the key difference of accounting for the scheduler fucking up some random bs. I don't like this hack but anyways maybe it fixes something?

* kernel/physical_core: Make use of std::unique_ptrLioncash2020-01-301-2/+2
| | | | | | | | | | | | | | | | | | shared_ptr was used in 8eb175481c7434c31e92b7cbc38ad3e881c33f3b due to a misunderstanding of how the language generates move constructors and move assignment operators. If a destructor is user-provided, then the compiler won't generate the move constructor and move assignment operators by default--they must be explicitly opted into. The reason for the compilation errors is due to the fact that the language will fall back to attempting to use the copy constructor/copy assignment operators if the respective move constructor or move assignment operator is unavailable. Given that we explicitly opt into them now, the the move constructor and move assignment operators will be generated as expected.
