nx2: rearm clean read areas when the GPU writes them again

2026-11-02T20:51:11+00:00

Port the coherency changes from alarok/Eglantine 77fc365f2 without its diagnostic framework or shutdown changes. Only GPU-dirty CPU reads become permanently preflushable, clean areas can be trapped on the next write, non-core readers avoid indexing core arrays, and collected CPU writes precede readback. Assisted-by: Codex (source review, selective integration and verification) (cherry picked from commit b64e211957180aa218ec6d9a3bcb020332279c3f)

Gpu buffer readback to cpu. Fixing visible glitches such as missing collision on some object, but can extend to more.

nx2: frame-locked input replay and quieter logs

2026-10-28T08:56:14+00:00

EDEN_NX2_KEY_RECORD records keyboard transitions as "f:code" against a global count of guest presents; EDEN_NX2_KEY_SCRIPT replays them on the same frames (or by seconds, as before), so a played session reproduces exactly. Debug aids: the PC/LR/SP of the first unmapped reads, NSO load addresses, EDEN_NX2_IPC_SUMMARY (request counts every 5 s), EDEN_NX2_FORCE_LOD0. Unmapped-access logging is rate limited and the per-draw/semaphore spam is demoted, so long sessions stay under the log size cap.

[video_core] buffer cache readback for nce invalidations (#4490)

2026-09-30T20:13:37+00:00

- [x] I have read and followed the [Contribution Guidelines](https://git.eden-emu.dev/eden-emu/eden/src/branch/master/CONTRIBUTING.md#code-contributions). - [x] I have read and followed the [AI Policy](https://git.eden-emu.dev/eden-emu/eden/src/branch/master/docs/policies/AI.md) - [x] I have read and followed the [Coding Guidelines](https://git.eden-emu.dev/eden-emu/eden/src/branch/master/docs/policies/Coding.md) to the best of my ability. ------------------- This is a follow up of 4473, a fix for the next Ender Magnolia known crash, the shackled beast's vaper crash, but specific for NCE. Imma try to be short: NCE invalidation was dooming whole guest pages when it shouldn't. If the GPU buffer cache owns some bytes on a page, invalidating first discards their ownership, and the retrying CPU can then observe stale data. On Android, this was corrupting some indirect draw packets and causing huge invalid index count reach staging memory allocation.

[common/core/dynarmic] Optimize page table allocations (#4219)

2026-09-09T19:35:49+00:00

Reduces the page entries from 32 bytes to 8 and rewrites `VirtualBuffer` to be more efficient in memory usage and specifically for large zero regions. The page table will now only reserve 1GiB instead of 4GiB and of this memory it should only use at most ~8MiB. This PR has the side effect of using Eden on Windows on low memory systems much more plausible since it would previously require ~10GiB of committable memory at front (despite using ~5-6 at most, inadvertently stalling other processes) where as now it should only require around the amount that it'll actually use.

[common/logging] Simplify logging logic and fix issues when logging before system is created (#3688)

2026-03-12T17:29:15+00:00

- our logging code was bigger than spdlog itself, why???? just keep it simple - fix issues when logging before logging system is even started - removes the "initialized logging twice" issue - removes uneeded indirection in file logging - uses direct formatting instead of jumping hoopla-around the fmt::format() ressult - code duplication and dead code removal as usual I did explore dup2() but I think it's not worth the hassle I did try `fwopen()` but it's better if things are just kept as-is. there is a lot of noise because I removed a bunch of redundant files on logging and just put everything in one file now normally this wouldn't be a good idea, however consider: the complexity of logging; it's less than 500 lines... does it really need a whole subsystem?!?!?!
