sceUserServiceGetAgeLevel reported 0. On a PS5 (firmware 13.60) the
value is the age of the user's parental restriction (0, 7, 12 and 15
measured) and 0xFFFFFFFF without one, so 0 is a user restricted to age
0. A user who is not logged in returns 0x80960009 (not logged in) with or
without an output, before the null output check.

Two more agc_driver_relative_indexing rows read a register of the window
the program never wrote, directly and through v_movrels_b32, and expect 0,
which the zeroed window array gives like an unwritten SSA register did;
the TechnicalDebt entry says the console's value is undefined.

M0 is unsigned, so an index at or past the window reads v0 and drops its
write, v_swaprel_b32 writes neither side when either is out of range, and
the window array starts zeroed like unwritten SSA registers; the window
load counts as a lane source so a wave64 program's second half keeps its
own registers. agc_driver_relative_indexing runs in wave32 and wave64 and
pins the rows measured on gfx1035 in the review of #3856, and the
TechnicalDebt entry states the measured behaviour, the window's end at the
last named register and the sizes.

The f16 unary ops, v_frexp_mant_f16, v_frexp_exp_i16_f16, the norm
conversions and v_cvt_f32_f16 read denormal halves as they are and
rounded denormal results as they are, whatever the denormal field of
FLOAT_MODE says. On RDNA2 a clear bit 0 flushes a denormal half input
to its signed zero and a clear bit 1 flushes a denormal half result.
One shared rule now drives all of them, and v_ldexp_f16 uses it for its
input too.

PPSA28416 calls it on its existing save at boot (after sceSaveDataDirNameSearch finds it) and aborted on the missing implementation. The call takes one parameter block: user id at +0, the directory name pointer at +8. Host saves have no size limit, so the conversion completes at once: an existing save returns OK, a missing one NOT_FOUND, an invalid name PARAMETER. The title polls sceSaveDataGetEventResult once afterwards and continues on 'no event'.
The search returned saves in host directory order and ignored the condition's key and order. A title that asks for the newest save first (modification time, descending) got whichever directory the host listed first: the alphabetically first on NTFS, an arbitrary one on Linux. Sort by directory name, user parameter or modification time, reverse for a descending order, and reject unknown keys and orders with the parameter error, as shadPS4 does.
PPSA06888 stops on main at start-up because its bundled
Media/Plugins/SceRudp.prx imports sceRudpEnableInternalIOThread2,
sceRudpGetOption and sceRudpGetRemoteInfo, which no library exports.
The signatures are unknown, so they are declared without parameters and
throw. The title does not call them during start-up.

sceKernelGetModuleInfoFromAddr has a Windows path since 77ef75c1d, so
_sceLibcInternalForceTlsDestructor finds each dso's module there too.
The test takes the other module's address with GetProcAddress where
Linux uses dlsym(RTLD_NEXT), and the TechnicalDebt entry no longer says
the call throws on Windows.
