PS4 firmware 10.71 converts "1.2.3.4" followed by a space, tab, LF,
VT, FF or CR, and anything after it ("1.2.3.4 x"), to 1.2.3.4 and
returns 1, where host inet_pton returns 0. Leading whitespace, other
trailing bytes (0x01, 0xa0), "1.2.3 " and IPv6 text with whitespace
still fail there.
A failed conversion leaves the destination and sceNetErrnoLoc
unchanged on the console; Winsock inet_pton writes the parsed prefix
before failing, so the conversion now goes through a local buffer.

v_mad_f32, v_mac_f32, v_madak_f32 and v_madmk_f32 exist only on gfx10.1,
so the RDNA2 oracle can't measure them. Measured on gfx1010 (RX 5700 XT)
in wave32 at IEEE 0 and 1, f32 denormal modes 0 to 3 and round modes 0
to 3, and in wave64, they round the product before the add, flush f32
sources, product (tiny after rounding with an unbounded exponent) and
result in every mode, and choose NaN results like the fma forms.
The behaviour stays left to the driver: translating it on every lane
cost about 15x main on the RX 5700 XT and 23x on an RTX 3070, and a
branch around the exact path still about 6x, so the lowering waits for
the SPIR-V float controls of #981.

The name hashes to zBsgF0q8DIM. Signature and error order follow the
OS 10.01 system module: NOT_INITIALIZED, INVALID_ARG for a NULL output,
INVALID_HANDLE for a bad handle. The emulated pad is not an Access
controller and reports 0.
The OS 10.01 system module checks only that the library is initialised,
then sends a per-process value to ShellCore over Mbus and returns 0 when
that call succeeds. It does not look at pad handles, so the throw while a
pad is open is gone. 0x809200ff, measured in a process that is not a game,
is the failed Mbus call; a game process is assumed to get 0.
kevent threw for EV_CLEAR on a socket or the read end of a pipe; Boost.Asio's kqueue reactor, among others, registers every socket that way. On Linux such a knote now watches its host descriptor through an edge watch. It is armed when added, on every later EV_ADD or EV_ENABLE while enabled, and by each host wakeup; when armed it is checked with the level-triggered readiness test and reported with the current data and EV_EOF, or disarmed if no longer ready, as kqueue_scan re-runs the filter; reporting it disarms it until the next edge. Waits block on the watch's epoll descriptor, so a socket that stays readable does not wake them. Windows and macOS still throw. GuestSockets::NativeDescriptor exposes the host socket behind a guest one for the watch.
The guest's second-kind Bessel functions return -inf and raise the divide-by-zero exception for x = +-0 (see e_jn.c), but the UCRT returns NaN for y1 and yn. Route x == +-0 through a shared helper, cover ynf(2, 0) in the guest math test, and note the special case in the libc technical debt.
The managed SceRudp.Rudp.EnableInternalIOThread in PPSA06888's Unity
metadata takes (uint stackSize, uint priority, ulong affinity), which
gives the signature. Like sceRudpEnableInternalIOThread it reports
RUDP_ERROR_NOT_INITIALIZED before sceRudpInit and success after it,
without starting a thread.

sceRudpNetReceived follows sceRudpNetFlush: it reports
RUDP_ERROR_NOT_INITIALIZED before sceRudpInit and success after it, since
no packets are ever received. sceRudpGetOption now has the signature its
PPSA06888 call sites use, (ctx_id, option, value, len), and still throws
because the option codes, defaults and errors are unknown.
