A ds_ordered_count with offset1 bit 4 set swaps the first active lane's value into the GDS counter instead of adding it. Emit it as one device-scope atomic exchange through the same path as the ordered add, and return the counter's previous value to every active lane.

An indirect draw read its count and records only after every stage had been captured and
compiled, so a draw whose records all have no vertices or no instances (what GPU-side culling
leaves for most draws in a culled scene) cost a full stage build to draw nothing.
When the front program's last indirect draw took the CPU path, the draw now reads its count and
records first, through the same flush hook, and returns before the stage build when no record
draws. APS5_NO_EMPTY_INDIRECT_SKIP=1 builds them as before. The [draws] profile line counts the
skipped draws. agc_driver_empty_indirect_skip_tests draws one record, two empty ones and one
more, and checks that the empty ones were skipped and the last one draws as the first.

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.

A layered draw into a color view of slices 0 to 5 of a 2D surface whose
CB_COLOR_ATTRIB3 declares one slice was refused. The CB clamps the
render target array index to the view's SLICE_MAX, not to the surface's
slice count, so each layer is written one slice pitch further on.
PPSA01317 renders a 512x512 cube map this way. Such a view now renders as
a 2D array of the view's last slice + 1 slices.

Export sceNpAuthGetAuthorizationCode (NID KxGkOrQJTqY) and
sceNpAuthGetIdToken (NID uaB-LoJqHis) in libSceNpAuth, delegating to the
corresponding V3 implementations.
Add test coverage in GuestNpAuth for both calls covering invalid
arguments, signed-out responses on sync requests, deferred async handling,
and unknown request IDs, as well as sceNpAuthGetAuthorizedAppCode. Update
technical debt documentation.
APS5_VIDEOOUT_TELEMETRY_DIR=<directory> appends one JSON object per line to <directory>/videoout.jsonl: a contract line for the run (commit and pid), a pad line whenever the published pad state changes in its buttons, sticks, L2 or R2, a present line after the first present and every 30 after that with the count and rate the window title shows, and a drops line with the number of lines the writer discarded, reported every ten seconds while it grows and once at a normal exit. A bounded queue of 4096 lines and one writer thread batch the file, so neither the present nor the input path waits for it; a pad change that the full queue refused stays pending for a later publish, and the frame count moves from UpdateTitle's function-static to DisplayWindow so the input path can name the present it belongs to.
Without the variable no file is opened and no thread is started: a present or an input update costs one call that checks a guard variable and returns null.
A RELEASE_MEM with DATA_SEL 4 was refused as "GDS RELEASE_MEM data".
amdgpu's GFX10 packet header gives 4 as the 64-bit system counter and 5
as GDS data. Validation now refuses 4 as the system counter, whose
console frequency and epoch are not known, 5 as GDS data and 6 or 7 as
reserved, and the debt file records the system counter.

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.

v_fma_f16, v_fmac_f16, v_fmamk_f16, v_fmaak_f16 and v_fma_mix_f32 with
f16 sources left the NaN of an invalid operation to the driver, so
inf * 0 gave 0x7fff and 0x7fffffff on NVIDIA where the hardware gives
the default NaN 0xfe00 and 0xffc00000. An inf * 0 product, or a NaN
from sources that are not NaN, now gives the default NaN; NaN sources
are still left to the driver.
MinGW libstdc++ up to GCC 16 does not treat a reparse point as a link in
std::filesystem::remove_all, so a host tree that holds a symlink is walked
through the link and never returns. Add RemoveTree, which removes the tree
itself on Windows, and use it where save data, app content and the shader
disk cache removed host trees. The libstdc++ fix is in GCC 17 (88856ad855ae).
Queue the stream in the table of the 8 standard stream
slots of Dinkumware's ios.cpp: the first free slot or the one
that already holds the stream, with a reference count per slot,
and the destructor suppresses the destruction of a standard
stream while its slot still has open references.
