* texture_cache: mark guest memory textures were uploaded from coldTakoroka3 days1-1/+1
| | | | | | | | | | | | | | Once a texture is uploaded the host GPU has its own copy, and the guest rarely reads that memory again, but it stayed in the emulator's working set. Every 600 frames the guest ranges of images uploaded since (64 KiB or more, not GPU-written or sparse) are marked cold through HostMemory::HintCold, backing and CPU view, from a low-priority worker, so the OS pages them out before anything else when it needs RAM. Their contents stay; using them brings them back. Mario Kart World's title screen at ~10 minutes: game memory in RAM 4.8-5.5 -> 3.6 GB, the emulator's real RAM 10.6-11.9 -> 9.4 GB, frames over 100 ms not worse. (cherry picked from commit ea36b2c5ca352f8c8cdcc829a2d3bde9bdc06ece)
* nx2: let the host page out texture pool backing firstTakoroka4 days1-0/+21
| | | | | | | | | | | | Switch 2 sparse blocks and GPU-only regions get guest memory when a game writes them (Mario Kart World copies 2-4 GB of compressed textures into its sparse texture pools) and the texture cache reads it again only when it builds an image there. Every 30 s, mark that backing cold: its pages leave the working set (VirtualUnlock on Windows, MADV_PAGEOUT on Linux) so the OS compresses or pages them out before anything else when RAM is short. The contents stay. Mario Kart World: 8.5 GB of RAM in use at five minutes instead of 9.0 GB on a machine with RAM to spare, frame times unchanged.
* [common/core/dynarmic] Optimize page table allocations (#4219)Exverge2026-09-091-12/+40
| | | | | | | | | | | | | | 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] Switch to boost::unordered_flat containers (#4326)crueter2026-08-311-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
