video_core: cheaper small GPU reads, buffer usage tracking and compute uniforms

2026-10-29T05:26:52+00:00

- MemoryManager::ReadBlockUnsafe reads within one 4 KiB page through a single translation (as Read does) instead of the page walk: texture and sampler descriptors, several per draw (2.6% -> 0.1% of title 1's GPU thread). - UsageTracker skips ranges it tracked just before (until Reset): draws bind the same multi-megabyte storage buffers again and again, and each Track wrote a word per 4 KiB (2.0% -> 0.7%). - Small compute uniform buffers the GPU has not written are streamed, as graphics ones are; synchronizing them re-protected pages an inline upload had just unprotected, two VirtualProtect calls per dispatch (1.9% -> 0.7%, page protection 3.2% -> 2.3%).
