From b884f93dd77e909d87a888e21d786e7ecb9d8daf Mon Sep 17 00:00:00 2001 From: Brian Degenhardt Date: Sat, 20 Jun 2026 20:27:55 -0700 Subject: [PATCH 001/292] arm64: build infrastructure, perf counters, and JIT perf-dump plumbing CMake/preset wiring for the ARM64 target, the vixl C++20 enum-conversion warning suppression, PmuCounters (cycle/instret PMU reads), and the Perf jitdump dir/enable controls (EmuConfig.Profiler.EnablePerfDump, redirected out of /tmp into the cache dir). Plus small platform/build fixes (ALSA thread naming, SmallString, X11 guards, ARM MIDR CPU-name fallback, gcc lambda decay). The ARCH_ARM64 status banner now reflects that EE/IOP/VU recompilers are all implemented.

When off, the Debugger/* sources, the KDDockWidgets find_package/link/DLL-copy, and the debugger entry points in MainWindow / QtHost / DebugSettingsWidget all compile out, dropping the dependency entirely on builds that don't ship the debugger.

the VTLB fastmem backpatch thunk (RecStubs), ArmAddressRecorder relocation hooks (AsmHelpers), and the cpuTlbMiss rec-vs-interp PC split (R5900) round out the arm64 memory layer. Windows arm64 is a no-op stub.

charset=UTF-8 Content-Transfer-Encoding: 8bit ARM64 microVU template JIT — dispatcher, compiler, upper/lower pipelines, flag and clamp handling, allocator and IR. Wires the VU recompilers into VMManager's CPU providers, ungates REC_VU1/THREAD_VU1 for arm64, and registers the arm64 source set (VUops.cpp/FPU.cpp get -ffp-contract=off so the interpreter stays bit-exact vs the two-rounding JIT).

Under register pressure that alloc spills a guest reg (or lands Rt in x0) and clobbers w0, so the unaligned load returns garbage. Single-op LWL/LWR tests stay clean — it only bites with several unaligned loads live at once. This is the 32-bit twin of the Black (SLUS-21376) LDL/LDR bug: when that fix landed it patched recUnalignedLoadDouble only; recUnalignedWord had the identical hazard. FlatOut 2 (SLUS-21251) tripped it — its property- table parser reads packed name pointers via LWL/LWR under heavy pressure, so the corrupted pointer made the game's own "PropertyDb: mapped buffer too small" assert fire (break 0,1), whose BIOS handler clears Status (IE=0) and strands the in-flight SIF0 completion, wedging the EE. Fix mirrors recUnalignedLoadDouble: park the loaded word in a callee- saved temp (allocated before the read) and use it in the merge. Test: EeRecLoadStore.MultiRegUnalignedWordCopyBlock — an 8-word unaligned memcpy via LWL/LWR + SWL/SWR across 4x4 src/dst alignments; red on the unfixed path, green with the fix. 1004 recompiler_tests pass.

That breaks self-contained and cross builds (e.g. the rocknix handheld toolchain) which have no system ryml available. Restore the in-tree copy (v0.10.0, from 0beb18c9e^) and point the build back at it: add_subdirectory(3rdparty/rapidyaml) instead of find_package, and link rapidyaml::rapidyaml. The C++ side needs no changes: common/YAML.cpp is already version-guarded (0804b68fc "Common: Fix build with older ryml", RYML_VERSION_MINOR >= 11) so it compiles against v0.10 unchanged. Also drop ryml.dll from the Windows dep-copy list since it's now statically linked. This is a deliberate fork-local divergence from upstream's un-bundling, kept so downstream builders don't have to provision ryml themselves. Configures without a system ryml and builds end-to-end (common + pcsx2-qt) using the in-tree library.

Because @ref ParseEngine is templated on the event + * handler, the binding uses static polymorphism, without any virtual + * functions. The actual handler object can be changed at run time, + * (but of course needs to be the type of the template parameter). + * This is thus a very efficient architecture, and further enables the + * user to provide his own custom handler if he wishes to bypass the + * rapidyaml @ref Tree. + * + * There are two handlers implemented in this project: + * + * - @ref EventHandlerTree is the handler responsible for creating the + * ryml @ref Tree + * + * - @ref extra::EventHandlerInts parses YAML into an integer array + representation of the tree and scalars. + * + * - @ref extra::EventHandlerTestSuite is the handler responsible for emitting + * standardized [YAML test suite + * events](https://github.com/yaml/yaml-test-suite), used (only) in + * the CI of this project. + * + * + * ### Event model + * + * The event model used by the parse engine and event handlers follows + * very closely the event model in the [YAML test + * suite](https://github.com/yaml/yaml-test-suite). + * + * Consider for example this YAML, + * ```yaml + * {foo: bar,foo2: bar2} + * ``` + * which would produce these events in the test-suite parlance: + * ``` + * +STR + * +DOC + * +MAP {} + * =VAL :foo + * =VAL :bar + * =VAL :foo2 + * =VAL :bar2 + * -MAP + * -DOC + * -STR + * ``` + * + * For reference, the @ref ParseEngine object will produce this + * sequence of calls to its bound EventHandler: + * ```cpp + * handler.begin_stream(); + * handler.begin_doc(); + * handler.begin_map_val_flow(); + * handler.set_key_scalar_plain("foo"); + * handler.set_val_scalar_plain("bar"); + * handler.add_sibling(); + * handler.set_key_scalar_plain("foo2"); + * handler.set_val_scalar_plain("bar2"); + * handler.end_map(); + * handler.end_doc(); + * handler.end_stream(); + * ``` + * + * For many other examples of all areas of YAML and how ryml's parse + * model corresponds to the YAML standard model, refer to the [unit + * tests for the parse + * engine](https://github.com/biojppm/rapidyaml/tree/master/test/test_parse_engine.cpp). + * + * + * ### Special events + * + * Most of the parsing events adopted by rapidyaml in its event model + * are fairly obvious, but there are two less-obvious events requiring + * some explanation. + * + * These events exist to make it easier to parse some special YAML + * cases. They are called by the parser when a just-handled + * value/container is actually the first key of a new map: + * + * - `actually_val_is_first_key_of_new_map_flow()` (@ref EventHandlerTree::actually_val_is_first_key_of_new_map_flow() "see implementation in EventHandlerTree" / @ref EventHandlerTestSuite::actually_val_is_first_key_of_new_map_flow() "see implementation in EventHandlerTestSuite") + * - `actually_val_is_first_key_of_new_map_block()` (@ref EventHandlerTree::actually_val_is_first_key_of_new_map_block() "see implementation in EventHandlerTree" / @ref EventHandlerTestSuite::actually_val_is_first_key_of_new_map_block() "see implementation in EventHandlerTestSuite") + * + * For example, consider an implicit map inside a seq: `[a: b, c: + * d]` which is parsed as `[{a: b}, {c: d}]`. The standard event + * sequence for this YAML would be the following: + * ```cpp + * handler.begin_seq_val_flow(); + * handler.begin_map_val_flow(); + * handler.set_key_scalar_plain("a"); + * handler.set_val_scalar_plain("b"); + * handler.end_map(); + * handler.add_sibling(); + * handler.begin_map_val_flow(); + * handler.set_key_scalar_plain("c"); + * handler.set_val_scalar_plain("d"); + * handler.end_map(); + * handler.end_seq(); + * ``` + * The problem with this event sequence is that it forces the + * parser to delay setting the val scalar (in this case "a" and + * "c") until it knows whether the scalar is a key or a val. This + * would require the parser to store the scalar until this + * time. For instance, in the example above, the parser should + * delay setting "a" and "c", because they are in fact keys and + * not vals. Until then, the parser would have to store "a" and + * "c" in its internal state. The downside is that this complexity + * cost would apply even if there is no implicit map -- every val + * in a seq would have to be delayed until one of the + * disambiguating subsequent tokens `,-]:` is found. + * By calling this function, the parser can avoid this complexity, + * by preemptively setting the scalar as a val. Then a call to + * this function will create the map and rearrange the scalar as + * key. Now the cost applies only once: when a seqimap starts. So + * the following (easier and cheaper) event sequence below has the + * same effect as the event sequence above: + * ```cpp + * handler.begin_seq_val_flow(); + * handler.set_val_scalar_plain("notmap"); + * handler.set_val_scalar_plain("a"); // preemptively set "a" as val! + * handler.actually_as_new_map_key(); // create a map, move the "a" val as the key of the first child of the new map + * handler.set_val_scalar_plain("b"); // now "a" is a key and "b" the val + * handler.end_map(); + * handler.set_val_scalar_plain("c"); // "c" also as val! + * handler.actually_as_block_flow(); // likewise + * handler.set_val_scalar_plain("d"); // now "c" is a key and "b" the val + * handler.end_map(); + * handler.end_seq(); + * ``` + * This also applies to container keys (although ryml's tree + * cannot accomodate these): the parser can preemptively set a + * container as a val, and call this event to turn that container + * into a key. For example, consider this yaml: + * ```yaml + * [aa, bb]: [cc, dd] + * # ^ ^ ^ + * # | | | + * # (2) (1) (3) <- event sequence + * ``` + * The standard event sequence for this YAML would be the + * following: + * ```cpp + * handler.begin_map_val_block(); // (1) + * handler.begin_seq_key_flow(); // (2) + * handler.set_val_scalar_plain("aa"); + * handler.add_sibling(); + * handler.set_val_scalar_plain("bb"); + * handler.end_seq(); + * handler.begin_seq_val_flow(); // (3) + * handler.set_val_scalar_plain("cc"); + * handler.add_sibling(); + * handler.set_val_scalar_plain("dd"); + * handler.end_seq(); + * handler.end_map(); + * ``` + * The problem with the sequence above is that, reading from + * left-to-right, the parser can only detect the proper calls at + * (1) and (2) once it reaches (1) in the YAML source. So, the + * parser would have to buffer the entire event sequence starting + * from the beginning until it reaches (1). Using this function, + * the parser can do instead: + * ```cpp + * handler.begin_seq_val_flow(); // (2) -- preemptively as val! + * handler.set_val_scalar_plain("aa"); + * handler.add_sibling(); + * handler.set_val_scalar_plain("bb"); + * handler.end_seq(); + * handler.actually_as_new_map_key(); // (1) -- adjust when finding that the prev val was actually a key. + * handler.begin_seq_val_flow(); // (3) -- go on as before + * handler.set_val_scalar_plain("cc"); + * handler.add_sibling(); + * handler.set_val_scalar_plain("dd"); + * handler.end_seq(); + * handler.end_map(); + * ``` + */ + +class Tree; +class NodeRef; +class ConstNodeRef; + + +//----------------------------------------------------------------------------- +//----------------------------------------------------------------------------- +//----------------------------------------------------------------------------- + +/** Options to give to the parser to control its behavior. */ +struct RYML_EXPORT ParserOptions +{ +private: + + typedef enum : uint32_t { + SCALAR_FILTERING = (1u << 0u), + LOCATIONS = (1u << 1u), + DEFAULTS = SCALAR_FILTERING, + } Flags_e; + + uint32_t flags = DEFAULTS; + +public: + + ParserOptions() = default; + +public: + + /** @name source location tracking */ + /** @{ */ + + /** enable/disable source location tracking */ + ParserOptions& locations(bool enabled) noexcept + { + if(enabled) + flags |= LOCATIONS; + else + flags &= ~LOCATIONS; + return *this; + } + /** query source location tracking status */ + C4_ALWAYS_INLINE bool locations() const noexcept { return (flags & LOCATIONS); } + + /** @} */ + +public: + + /** @name scalar filtering status (experimental; disable at your discretion) */ + /** @{ */ + + /** enable/disable scalar filtering while parsing */ + ParserOptions& scalar_filtering(bool enabled) noexcept + { + if(enabled) + flags |= SCALAR_FILTERING; + else + flags &= ~SCALAR_FILTERING; + return *this; + } + /** query scalar filtering status */ + C4_ALWAYS_INLINE bool scalar_filtering() const noexcept { return (flags & SCALAR_FILTERING); } + + /** @} */ +}; + + +//----------------------------------------------------------------------------- +//----------------------------------------------------------------------------- +//----------------------------------------------------------------------------- + +/** This is the main driver of parsing logic: it scans the YAML or + * JSON source for tokens, and emits the appropriate sequence of + * parsing events to its event handler.

Both microVU backends share a byte-identical cycle model, so the same capture+budget stops at the same guest insn on either arch -- post-states are directly comparable even for budget-truncated programs, the class JIT-vs-interp is structurally blind to. - --vu-clamp-mode N: force EmuConfig VU clamp mode 0..3 (mirrors GameDatabase.cpp vuClampMode). The harness otherwise stays at default mode 1 (vu0Overflow only), which never exercises the extra-overflow per-op operand clamp real games request via gamedb (e.g. SoulCalibur III vuClampMode:2). - RunDiff also reports consumed-cycle divergence (gated on both engines hitting the E-bit) -- the EE<->VU0 timing quantity the reg/mem diff can't see. - VuReplay records jit_cycles/interp_cycles deltas. - x86 portability: guard the arm64-only progcache/persist includes+calls so the same source builds a native x86 vurunner for the cross-arch reference.

Match x86 microVU_Compile.inl doUpperOp(). Adds 4 RED-before / GREEN-after regression tests (Vu0Qpipe.*InJitStatus, VU0 + VU1) that assert the bit on the JIT side directly, padding past the 7-cycle flag latency so mVUdivSet has a downstream instruction to fold the flag.

Single-scalar FMAC ops rotate the live lane to lane 0 (shuffleSSto0), clamp+operate on lane 0, then rotate the siblings back (shuffleSSfrom0), so the values parked in lanes 1-3 must survive the clamp. Zeroing them clobbered carried state (e.g. the ACC accumulator across single-component MADD chains) -> garbage vertices -> SoulCalibur III (SLUS-21216) trembling character geometry (SPS). Only bites at vuClampMode:2 (SC3's gamedb mode) -- the per-op extra-overflow operand clamp; default mode 1 never emits this path, which is why the harness, the cross-arch corpus and shadow-diff all missed it for months (all ran mode 1). Fix: compute the clamped scalar in RQSCRATCH3 and INS it back into lane 0 only, mirroring the x86 SS path. Reference lineage: an early reference ARM64 PS2 implementation had the same scalar-S lane-zeroing -- ours inherited it; a later reference build fixed it by clamping the full V4S. Our fix takes the x86 shape (lane 0 + Ins). Proven via the cross-arch JIT-vs-JIT corpus at --vu-clamp-mode 2 (arm64-rec vs x86-rec: 3153 diffs -> 0; mode 1 stays 0) and live-verified in-game.

The preload loop walks until it runs out of free host registers, breaking only on doXGKICK / lOp.branch — never on the E-bit. An E-bit-terminated block (no branch) therefore runs the preload PAST its own end, and since mVUreset does not clear mVU.prog.IRinfo.info[], it reads VF/VI usage left by a PRIOR compile and preloads registers the current program never touches. Runtime behaviour is unchanged (it is an unused-register load), but the emitted bytes then depend on compile history — non-deterministic codegen. In a cold cache the stale entries read zero (reg 0 -> skipped), so the cold shape is unaffected; this only suppresses the spurious warm-state preloads. That is exactly what the persisted-JIT ABI digest guards, so the drift surfaced as order-dependent failures in MvuAbiDigest under --gtest_shuffle. Fix: break the preload at info->isEOB, mirroring the analysis loop's own termination. Diverges from x86 (same latent over-read there, but no on-disk cache that needs deterministic emit). Same spirit as the flagInfo "clear each compile" fix in mVUinitFirstPass. Adds MvuAbiDigest.EmittedShapeIndependentOfPriorCompile — a deterministic guard (compile a probe after two polluters that seed different VI reads past the probe's end; the probe digest must match). Red before this change, green after. The existing pin test only caught it under --gtest_shuffle.

Port Stenzek's x86 mVUoptimizeConstantAddr: instead of emitting moveVIToGPR + imm-add + mVUaddrFix (mask/shift) + Mem-load + base-add, collapse to a single Mem-pointer load plus at most one immediate add, then run the existing load/store. Typical vi00 loadstore drops from ~6 emitted insns to 2 (VU0 in-range offsets fold the byte offset into a single add immediate). The VU0 cross-VU-register window (addr & 0x400) and the IbitHack runtime-reconstruct path keep the existing runtime mVUaddrFix path. This postdates the reference ARM64 PS2 implementations we track, so it's adopted under the "newer correct upstream pattern" rule; the helper mirrors x86 1:1 in semantics (arm64 returns the folded base in a register rather than an x86 memory operand). Bumps kMvuCompilerAbiVersion 3 -> 4 (+ versioning mirror) since mVU codegen changed; evicts on-disk VU program caches recorded with the pre-fold shape. The ABI-digest probes use no LQ/SQ/ILW/ISW, so their pinned digests are bit-identical (re-pinned to abi 4 unchanged). Adds Vu1AluLower.{Lq,Sq,Ilw,Isw}Vi00*FoldsToConstAddr covering all four folded ops at a non-zero quad offset; Run() auto-diffs the folded JIT against the interpreter. 1016 recompiler_tests pass, shuffle-clean seeds 1-40.

The shared machinery (CalculateMinRunCycles, the ExecuteBlockJIT interlocked param, s_nBlockInterlocked) was already merged from upstream, but arm64's recompiled COP2 ops sync VU0 via cop2EmitConditionalSync -> vu0Sync, not via ExecuteBlockJIT — so the 16-cycle floor never fired and every non-interlocked catch-up dispatched VU0 by the exact (often tiny) delta, paying the full mVU dispatch envelope to run as little as 3 cycles. vu0Sync gains a run-ahead sibling (vu0SyncRunAhead) that floors the sync-only catch-up at 16 cycles; the non-interlock branch of cop2EmitConditionalSync emits a call to it. Overshoot is bounded and self-limiting — the next sync sees a negative delta and no-ops until the EE catches up — so several round-trips collapse into one. This directly trims VU0 dispatch-envelope / exit-thunk cost, two of our top-three remaining JIT overheads, on exactly the workload the upstream commit names (Ratchet & Clank's intro). An interlocked COP2 op anywhere in the block sets s_nBlockInterlocked (reset per block in recRecompile, beside s_nBlockCycles), which forces the exact vu0Sync for the rest of the block so a later interlock can't be overshot — mirroring upstream's block-level flag. No new test: the run-ahead only diverges from the exact path mid-program (final VU0 state converges deterministically), so it's invisible to the JIT-vs-interp harness by construction; all 1016 recompiler_tests pass unchanged. Magnitude is workload-dependent and validated on hardware.

The correctness half (the _Funct_ >= 074 guard in the COP2FlagHackPass) already ships in the shared x86/iR5900Analysis.cpp the arm64 build compiles. setupMacroOp_arm64/endMacroOp_arm64 emitted cop2EmitDenormalizeStatusFlag (~11 insns) and cop2EmitNormalizeStatusFlag (~10 insns) unconditionally for every status-updating COP2 FMAC. With vuFlagHack on (the production default) the shared COP2FlagHackPass already tags every status write that reaches a CFC2 with EEINST_COP2_STATUS_FLAG — sticky reach included, since the tag is applied to all writes before the next CFC2 (apc < m_cfc2_pc). A write that reaches no CFC2 is dead, so the denormalize/normalize dance is pure dead emitted code. Gate both on a shared cop2StatusFlagLive() predicate (same EEINST_COP2_STATUS_FLAG gate the adjacent mVUmacroSetupCOP2State already uses for the mVU-reuse path); setup and teardown skip in lockstep so a denormalize never lands without its normalize. arm64 re-seeds s_cop2DenormStatusFlag from VU0.VI[REG_STATUS_FLAG] every op (no x86 gprF0 cross-op persistence), so this is the dead-status *subset* of the upstream change and needs none of that persistence: the live path still normalizes to the architectural register every time, and a dead op's leftover scratch scribble is overwritten by the next live op's denormalize. The x86 "first denormalizer" marker EEINST_COP2_DENORMALIZE_STATUS_FLAG is therefore intentionally not in the gate. Since vuFlagHack defaults on, this trims emitted code volume on COP2-macro FMACs in real gameplay. Test infrastructure for the flaghack path: - RecompilerTestEnvironment pins vuFlagHack OFF for JIT-vs-interp determinism (it lets the JIT skip status updates the always-accurate interpreter still performs — the same determinism rationale as the existing vuThread/ vu1Instant pins). This was an oversight; flaghack defaulted on in tests. - mvu_abi_digest_tests forces vuFlagHack back ON inside CompileAndDigest so the ABI digest keeps pinning the production-cached mVU shape (digests are bit-identical — the only change was the harness default). - EeRecTestHarness::RunJitNoDiff now captures the VU0/VU1 snapshots (it only captured EE state, so GetVu0Vf* read a stale prior-test snapshot — an order-dependence the new dead-status test surfaced under --gtest_shuffle). - Two EeVu0Cop2MacroFlagHack tests opt back into flaghack: status-live across a CFC2 (auto-diff: the gate must keep the normalize, JIT == interp) and status-dead standalone (JIT-only: the skip must not disturb the arithmetic). 1018 recompiler_tests pass, shuffle-clean seeds 1-40.
