Performance diagnostics and small wins for title 1

2026-10-28T20:44:24+00:00

- 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=:: 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)

2025-11-03T19:36:38+00:00

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?
