Source changes (dormant parity infra, retained from iterate 2.AI/2.AO): - xenia-kernel/exports.rs: nt_create_event manual_reset polarity + related event wiring - xenia-gpu/mmio_region.rs: D1MODE_VBLANK_VLINE_STATUS hardcode parity Also lands the audit-runs/ analysis notes (.md/.txt/.json digests) for the iterate 2.x VSync/0x10e8/0x1004 wedge investigation. Raw trace dumps (.jsonl/.gz/.csv/.stdout) and agent worktrees (.claude/) are gitignored as regenerable local artifacts — see memory + HANDOFF for the running findings.

# AUDIT-061 — conditional branches in sub_821C4EB0 [+0x44, +0xE0] = [0x821C4EF4, 0x821C4F90]
|
|
# Format: PC <tab> mnemonic <tab> target <tab> annotation
|
|
#
|
|
# Range covers PCs from 0x821C4EF4 (cmplwi setting cr6 for branch B1) through
|
|
# 0x821C4F90 (final bgt cr6 of the cmplwi r11,3 jump-table guard).
|
|
#
|
|
# B0 entry probe (function entry) — for sanity-check call counting.
|
|
0x821C4EB0 entry - function entry — count calls to sub_821C4EB0
|
|
#
|
|
# Conditional branches:
|
|
0x821C4EF8 beq cr6 0x821C4F20 after cmplwi cr6, r3, 0 (r3 = sub_82150EF8 return).
|
|
0x821C4F3C bne cr6 0x821C4F7C after lbz r10, 12932(0x828F<<16)+cmplwi r10,0 — byte test of static flag.
|
|
0x821C4F70 beq cr6 0x821C4F78 after lwz r3, 92(r30) — skip bl 0x824AA3E0 when *(r30+92)==0.
|
|
0x821C4F90 bgt cr6 0x821C5000 after cmplwi cr6, r11, 3 — guards 4-entry jump table at 0x821C4F94..0x821C4FAC.
|

|
|
# Post-bl PCs we want to count too (taken-paths to sub_821CEDF8 etc.):
|
|
0x821C4F14 bl 0x821CC3F8 call to sub_821CC3F8 (the canary-only 5x callee per AUDIT-056? — actually sub_821CEDF8 is the one, this is sub_821CC3F8). Will instrument to count.
|
|
0x821C4F2C bl 0x82187C30 call to sub_82187C30 — AUDIT-056 caller-LR.
|
|
0x821C4F60 bl 0x82172370 call to sub_82172370 — significant downstream caller.
|
|
0x821C4F74 bl 0x824AA3E0 call to sub_824AA3E0 — KE/ wait-related? Conditional on prior beq.
