* Switch 2: title 4 menu text renders uprightTakoroka7 days1-0/+18
| | | | | | | | | | | - Present flips the image vertically: title 4 renders with a lower-left origin (negative viewport scale), so its frames are stored bottom-up. - Lowering: TEX/TEXS FP16 results (bit 79, packed half pairs) - the glyph shaders unpack them with HADD2.F32; LDG.E with a register address; SHF.R.U32 low word with a zero high word. - Debug aids: EDEN_NX2_TRACE_PS / EDEN_NX2_WINDOW_TRACE_SKIP for the window trace, EDEN_NX2_TEXTURE_DUMP, EDEN_NX2_TRACE_DST for copies; RT trace keyed by shader pair. NX2_NOTES: blockers 53-57, next steps.
* Switch 2: Turing macros, native compute, Ampere shader lowering, native tilingTakoroka7 days1-4/+13
| | | | | | | | | | | | | | | | | From changes.patch: the TU104/GA10x MME interpreter (shared macro context for the process's channels, also on the compute class), native compute with QMD 3.0 dependency scheduling, the Ampere-to-Maxwell shader lowering, native vertex stream sizes, and the console's GOB swizzle for textures, DMA copies and the host unswizzle shaders. Switch 2 channels turn all of it on at init. The lowering is widened for title 4 (all 32 of its programs lower): general TEX (any dimension/LOD/mask, operand split 1+1/2+1/2+2/4+n, any but consistent descriptor buffer), cube/array, SULD channel masks, 128-bit STG, indexed IPA, VOTE, SHFL with any immediate or predicate output, R2P/P2R byte select, uniform ULOP3/ULEA/UBREV/UFLO.SH/UISETP signed/UMOV URZ, IMNMX cbuf, IADD3 and FFMA uniform operands, FMUL /4 /8 x8, and BSSY/BSYNC/BREAK/WARPSYNC as no-ops. The capture stops at unmapped memory. EDEN_NX2_SHADER_DUMP dumps every native program; tools in C:\dev\nx2work test the lowering offline.
* Switch 2: suspend channels on semaphore acquires; fix pushbuffer desyncsTakoroka7 days1-1/+5
| | | | | | | | | | | | | | | | NVN2 gates command buffers with semaphores the CPU releases after writing them. Eden read past unmet SEMAPHORED acquires, so it executed stale commands and desynchronised. Channels now suspend on an unmet acquire and resume from the same word once it is met (scheduler keeps the waiting channels, the GPU thread polls them), as in changes.patch. Also: methods split across GPFIFO entries around a called command buffer are set aside and resumed; subchannel 2 defaults to inline-to-memory; unbound subchannels and out-of-range compute/DMA methods are dropped instead of crashing; 4-byte semaphore releases no longer write 16 bytes; Ampere SEM_PAYLOAD_HI/SEM_EXECUTE no longer spin as Kepler acquires; unmapped GPU reads log instead of asserting. Debug aids: EDEN_NX2_PB_CHECK (pushbuffer changed after submit), EDEN_NX2_QUERY_TRACE, a one-time pushbuffer dump.

* [common/logging] Simplify logging logic and fix issues when logging before ↵lizzie2026-03-121-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | system is created (#3688) - 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?!?!?!

* [vk] Implement Shader Read Barrier (#2671)Ribbit2025-10-041-0/+2
| | | | | | | | | | | Adding the shader read barrier keeps every render/compute/transfer write visible before the image is sampled, so it prevents the “read-before-writes-finish” hazards. Without it you can get random stale frames, flickering post process passes, partially updated HUD textures, and corrupted depth-to-color conversions especially in scenes that render into an offscreen image and immediately feed that image to a shader (reflections, bloom, dynamic resolution, depth visualizers, etc.). This fix makes those R2T chains deterministic again across all Vulkan drivers.
