 | 81 | title 1 hangs before its first frame (~17 s): main logic stops, two cores spin, only audio and hid keep running, almost no GPU submits | it asks gpu 214 for ~20 GiB (two 0x16ad80000 regions, these two still fail with the new pool); gets further than before (save data, friend list) | open: thread snapshot at the hang; 214 regions this large must be sparse on the console |
 | 82 | title 1 hang (row 81) | `monitor handles` (a4051e4) showed the main thread waiting forever on the nx2:vi2 32 event (loop at main+0x25ec5e4 until [obj+0x88] >= 2); the stub never signalled it | 31 and 32 events signalled at 60 Hz (6196a11); title 1 now presents (241 frames by 95 s) |
 | 83 | title 1 after the hang: ~3 fps with "fence not reached in 4 s" stalls | unimplemented vi2 104/105 (every frame) and gpu 215, gpu 214 still short for the two 5.7 GiB regions, one Nx2Map "out of SMMU space", rejected shaders (formatted surface store, IPA mode, LEA carry) | open |
+| 84 | title 1 GPU stalls (row 83): channels wait on semaphores 0x21f6093140/3040 until the 4 s timeout | NVN2 queue syncs run through a ring of QMDs (dependency 2 each: the previous entry's launch and macro 0xda, which patches release slot 52 and schedules/decrements via PCAS 3/7); macro 0xda reads the ring base from MME data RAM word 0x27, which each channel sets (0x21098d39, 0x213e8ff8, 0x213ea168) but Eden shared one data RAM for all channels, so every channel drove the same ring | per-channel MME data RAM, one QMD table for all channels (6c20e37); no stalls, title 1 reaches its title screen (world map with logo) |
+| 85 | title 1 address space | 214 = CreateSparseRegion, 215 = DestroySparseRegion (SDK symbols); SMMU space (16 GiB) ran out | 64 GiB device space (71b38ab), 215 handled (cc0c400) |
+| 86 | title 1 after its title screen: black frames | tens of thousands of rejected shaders: IPA interpolation modes, integer carry/third source, uniform comparison, formatted surface load/store, uniform constant load, unsupported opcodes | open |
