* perf: answer Turnip's zero-timeout KGSL timestamp polls without blocking Turnip polls a timeline point with IOCTL_KGSL_DEVICE_WAITTIMESTAMP_CTXTID and a timeout of 0, which KGSL reads as wait forever; Mesa does it under a lock on every signalling submit, so vkd3d-proton, DXVK, gamescope and Zink ran in lock-step with the GPU. The session preload now answers those polls from the context's retired timestamp and passes everything else to the kernel. Bannerlator measured a D3D12 demo at 614 -> 4335 fps with the same answer in its Vulkan adapter. BL_NO_KGSL_POLL_FIX=1 turns it off. * perf: frame limiter, live panel refresh, opt-in GPU clock pin, cheaper cursor sync - A per-mode frame limit (Steam and desktop settings, off by default): gamescope's -r, the compositor's buffer-release pacer, the display layer's frame-rate vote and a panel mode the cap divides evenly, as WinNative's per-shortcut limit does. BL_FPS was always 0 and the pacer's limit was never set. - The compositor follows the panel's refresh rate when it changes mid-session instead of reporting the rate read at start. (WinNative.) - Performance > GPU: hold the Adreno clock at its top through KGSL's power-control property, no root (Bannerlator's PerfGpuTurbo). Off by default; cleared when the session stops and at the next app start if a killed process left it set. - The cursor image is copied across JNI only when its serial changes, not on every pointer move. * perf: stop re-seeding every prefix every 5 s, and run the library helpers only on change - bannerlator-seed-redists stamped its change check from a block that carried the current time, so it never matched: every prefix had ~32 keys appended to system.reg on every beat. The stamp now comes from the names; Proton's prefix template is seeded too (date kept), with WinNative's built-in list until the client has the install scripts. - The library beat runs the seeder every 15 s and steam-compat only when a directory it reads has changed, or once a minute. - The client-core pin reads /proc itself and runs taskset -a only for new processes or ones that grew threads. - The games watcher backs off after a failed ownership probe and does not probe while a game runs. - The Proton launcher runs the newest ARM64 depot by build number, and PROTON_USE_PIPEWIRE defaults to 0. (WinNative.) * perf: Mesa's database shader cache, and proot's tracer above the guest - MESA_DISK_CACHE_DATABASE=1 for the session: the file cache opens a file per lookup and opens and renames one per store, each a proot stop; the database is opened once and used with pread/pwrite. - proot's single tracer thread is raised to nice -6 (under the compositor's -8) two seconds after it starts, so the first guest process it forks keeps nice 0. setpriority() directly, not Process.setThreadPriority, which would also move its cgroup.
