sceAgcDebugRaiseException (NID T6xuVw0KUJo) now logs the exception id
with APS5_LOG_OUT and returns 0, as libkernel's
sceKernelDebugRaiseException does.
Palworld PPSA23126 (#2598) and 007 First Light PPSA11386 (#2523) import
it; neither is shown calling it.
OpenAGC 3c7e8072 (src/game_compat.c) returns 0 and says the function is
a no-op on retail hardware; the ud2 trap it describes for development
hardware is not reproduced. KytyPS5 6f0cddd4 (src/libs/agc.cpp) takes a
uint32 exception_id, logs it and returns 0. OpenAGC declares no
arguments, but a body that only traps reads none, so the uint32 is kept
and the conflict is recorded in TechnicalDebt. The aerolib name is from
zecoxao/sce_symbols 2883963a; ps5-payload-dev/sdk f5d40f02 has only an
untyped stub.

image_sample_c_lz on gfx1035 returns 0 for 8-bit sRGB, so the unorm clamp was the wrong result. Bilinear cube comparison without DISABLE_CUBE_WRAP keeps throwing because that filter blends across faces.

On an RTX 4060 (Ada, driver 617.42) the optimized link of a pipeline built
from libraries loses the device (VK_ERROR_DEVICE_LOST) as soon as it is
bound, which fails agc_driver_pixel_valid_mask in 16 of 20 runs. With
APS5_NO_PIPELINE_LTO=1 it passes 20 of 20. Reporters see the same loss on an
Ampere card with a depth attachment; two Blackwell cards do not lose it.
A device whose driver is VK_DRIVER_ID_NVIDIA_PROPRIETARY keeps the
fast-linked pipeline and no longer queues the link-time-optimized relink.
Other drivers are unchanged.

GuestMemory.cpp reads PROCMAP_QUERY_VMA_READABLE and PROCMAP_QUERY_VMA_WRITABLE from the query result. The fallback for kernel headers without PROCMAP_QUERY now defines them too, so GuestMemory can use this header instead of its own copy.
The icon, title and output path are checked before the ELF is written,
so a malformed icon0.png or param.json leaves no output behind. Paths
with control characters are refused instead of producing an invalid
entry.
Co-Authored-By: Claude <[email protected]>
ELF has no icon resource, so when sce_sys/icon0.png sits beside the input
the relinker copies it next to the output and writes <output>.desktop
(freedesktop Desktop Entry) with that icon. Name is the param.json title
without trademark signs or line breaks, or the output name without
param.json. Exec is quoted per the spec and the entry is marked executable
so file managers launch it. A malformed icon0.png or param.json fails the
relink; without icon0.png nothing extra is written.

sceAgcFuseShaderHalves returns a fused hull as a copy of its back half
(type 7) that is not registered: type 3, no user data, and shader
registers copied to scratch memory with the checksum, RSRC1/RSRC2 and
the LS program address rewritten. sceAgcCreatePrimState accepts only that
type-3 header, and graphics ABI resolution refused it as a replaced
shader header.
SameHeader now also takes a type-3 header as the registered type-7
header for the same code when every other field is equal and its shader
registers differ only in the fused ones. Graphics ABI resolution then
applies the bound header's shader registers over the registered state.
PPSA26344 fuses its hull halves during its loading screen.

One 4-page direct mapping loses its second page to munmap, then pages
1-2 are mapped fixed. The range starts in the hole; before the fix the
unmap of the overlap threw "guest protection or unmap range has a
hole". The pages around it keep their data.

Subnautica Below Zero stops while compiling a menu shader that compares an sRGB color texture or a bilinear cube face. sRGB uses the unorm reference clamp, and a bilinear cube sample stays on the face it hits.
Written with AI assistance.
GuestAllocationsUnmap took the piece containing the cursor from the
allocation's original extent. After part of an allocation was unmapped,
a later unmap or fixed map starting in that hole still matched the
allocation, and replaceRange threw on the hole. Match against the
registered range itself and end each piece at its end. RIDE 4
(PPSA01599) maps fixed over a partly unmapped direct memory range.

A child process runs from a root whose app0/sce_sys/playgo-chunk.dat
declares 3 chunks: ids 0-2 are local, id 3 is rejected with
SCE_PLAYGO_ERROR_BAD_CHUNK_ID and scePlayGoGetChunkId counts 3.
Co-Authored-By: Claude Opus 5.5 <[email protected]>
Without playgo-chunkdefs.xml every chunk id was accepted, so a title
that probes chunk ids until SCE_PLAYGO_ERROR_BAD_CHUNK_ID never stops.
RIDE 4 (PPSA01599, Unreal Engine 4) grows its chunk list until it runs
out of memory. The package's chunk table header holds the chunk count
at offset 0x0A; ids below it are valid. Every id is still accepted only
when neither file exists.

FreeBSD fchdir(2) changes the working directory to the directory referenced by a descriptor. The guest imports fchdir from libkernel_sys (PPSA99764, issue #1578) and the module did not export it.
The descriptor's directory is resolved from the path recorded when the directory was opened on Windows, and from the /proc/self/fd link target on Linux. The guest working directory is then set through the libc routine shared with chdir. A descriptor that is not open returns EBADF and one that is not a directory returns ENOTDIR.

`truncate` (`ayrtszI7GBg`) is an absent import of PS5MC (PPSA99420),
XPSemu (PPSA97358) and Porpoise (PPSA99764) on `main`. It resolves
through `sceKernelTruncate`, which now returns `EISDIR` for a directory
and the host errno for other failures instead of `EIO`, as FreeBSD 11
`kern_truncate` does. The guest-relative test `guest_truncate` covers
shrinking, growing with zero fill, a negative length, a missing path,
an empty path, a null path, a directory and a read-only file.

hypot(inf, NaN) returned a NaN on main. C Annex F returns +inf when
either operand is infinite, even if the other is a NaN, and FreeBSD
msun (lib/msun/src/e_hypot.c) does so for a signalling NaN too. The
infinite case is now checked before std::hypot; other inputs do not
change.

#698 taught the reader, the module builder and the Windows writer to
resolve relocations against SHN_ABS symbols and to leave them out of the
exports, but the macOS writer still threw "Unsupported guest export
section" for them. PPSA12544 bundles modules with such an export
(RKDbTdN8TO0), so --macos stopped before writing anything.
The macOS writer now resolves a relocation against an absolute symbol to
its value plus the addend, without a rebase, and skips absolute symbols
when exporting, as the Windows writer does. guest_absolute_symbols covers
the macOS output too.

C17 7.21.6.2p16 returns EOF only if input fails before the first conversion completes, and a suppressed conversion completes. FreeBSD counts it in nconversions (vfscanf.c, releng/11.4, lines 799-805). The host scanf returned EOF there, so sscanf("12", "%*d%d", &v) reported EOF instead of 0. Each suppressed conversion now records its end with a %n and a result of EOF becomes 0 when one was recorded.
