v_ldexp_f16 ignored the FLOAT_MODE denorm16 flush bits on main. Flush a
denormal half input when bit 0 is clear. When bit 1 is clear, flush the
result when its exact value is below the minimum normal half, decided
on the f32 product before the half conversion rounds it: 0x07ff scaled
by 2^-1 is zero on RDNA2, not the minimum normal. NaN handling and
destination high-half preservation stay the same.

A fill was taken to cover the surface when it spanned ceil(w/8)*ceil(h/8)*4 bytes, a linear HTILE layout. In
the pipe-aligned SW_64KB_Z_X layout a surface's HTILE words lie across a 32 KiB metadata block per 1024x512
pixels (AMD PAL gfx10 addrlib: a 16x16 surface has a valid word at offset 260), so a fill of the linear size
cleared tiles it never wrote. HtileMetadataBytes gives that extent; the fast clear tests fill it (the compute
fixture now dispatches one group per KiB with TGID_X).

Rebased onto main as one commit (the six commits of #374). A uniform fill over a depth surface's whole
HTILE (DMA_DATA, the fill kernels or a CPU store) clears the depth and stencil aspects its ZMask and
SMem fields say, to DB_DEPTH_CLEAR / DB_STENCIL_CLEAR, when the surface is next bound or sampled.
Main's RADV clear_htile_mask recognition (#2229) now goes through the same pending clear: an HTILE clear
marks the matching surfaces' depth aspect, and one for a surface not created yet is applied when it is
first bound. Main's HTILE address decode and this one are merged into one (TILE_SURFACE_ENABLE, a
nonzero DB_HTILE_DATA_BASE and a depth format).

A system SDL2 that does not define SDL_JOYSTICK_HIDAPI (sdl2-compat over
SDL3 ships no such macro, and neither does a build with the driver
disabled) fails pad_sdl and makes the disk audio driver open the port
with a different channel count, so ANYPS5_USE_SYSTEM_DEPS=ON now rejects
it with a named error, like the VK_KHR_maintenance8 check. Ubuntu's real
SDL2 defines the macro through its SDL_config.h indirection and is
unaffected.
SPIRV-Tools only exports SPIRV-Tools-static when built with
SPIRV_TOOLS_BUILD_STATIC=ON; distributions that ship it shared expose
SPIRV-Tools instead, so a shared target is aliased to the static name.
Resolve SDL2, freetype, Vulkan-Headers, SPIRV-Headers, glslang and
SPIRV-Tools from the system instead of the bundled submodules when the
option is ON. It is OFF by default, so the bundled build is unchanged.
Every package is required: a missing one, or Vulkan-Headers older than
1.4.310 (the agc driver uses VK_KHR_maintenance8), fails the configure
with an error and nothing falls back to the submodule. The system
packages are exposed under the same target names the bundled path uses,
so the rest of the CMake is untouched.
SDL2 is linked from the system as a shared library because the prx
libraries are shared objects and distribution static SDL2 is usually not
PIC. ffmpeg-core, libjpeg-turbo, stb, VulkanMemoryAllocator and LibAtrac9
stay bundled.
sceSharePlayGetCurrentConnectionInfoA now writes a 72-byte
SceSharePlayConnectionInfoA that reports no session: status DORMANT,
mode 0, empty online IDs, account IDs 0 and both user IDs invalid (-1).
A null pointer returns SCE_SHARE_PLAY_ERROR_INVALID_ARGS (0x810E0001)
instead of throwing. KytyPS5 and fpPS4 agree on the layout and the error
code; KytyPS5 sets the user IDs to -1, fpPS4 leaves them 0.

Relinks the ELF modules of extra directories under the module parent directory. Modules the executable or another module needs start with the executable; the others are initialized when the title loads them with sceKernelLoadStartModule, with its start arguments (Windows: __aps5_guest_initialize export; Linux: left out of DT_NEEDED).
Squashed onto main by the reviewer (history had a merge commit).
Explicit-LOD offset samples through FORCE_UNNORMALIZED samplers now add
sign-extended texel offsets to f32 coordinates before clamping, using
OpFAdd with NoContraction and a sampler specialization selector.
Without native nonconstant-offset support, retain only runtime image
modes valid for unnormalized sampling and reject normalized samplers.
Preserve constant-swizzle handling, indirect-image rejection and main's
flat-volume and flat-line compatibility rules when selecting those modes.
Serialize image compatibility and folding flags and the sampler folding
flag in cache format 34, with roundtrip, preparation and execution coverage.
Retain main's request format 15 and runtime ABI 11.
Measured on a PS5 (firmware 13.60):
- sceSslGetMemoryPoolStats returns 0x8095F007 for a null output, before
the id check, and 0x8095F006 for an unknown or terminated context,
zeroing the 32-byte output.
- sceHttp2GetMemoryPoolStats returns 0x817B1225 for a null output,
before the id check, and 0x817B1100 for an unknown or terminated
context, zeroing the 32-byte output.
- sceNetGetMemoryPoolStats checks the pool before the output, so an
unknown pool with a null output returns EBADF.

VLC (PPSA85300) imports daemon (Wn6I3wVATUE) and fails to load because
no library exports it. Forking into the background is not supported,
so it throws if called. VLC 3.0 calls daemon only when its daemon
option is set, and the title starts libVLC with --ignore-config and
without --daemon.
#3158 imports a run of address-adjacent registered ranges as one span.
On Windows a shared mapping in the span needs a read-write alias, and
MapAlias refuses one unless the range is a single contiguous run of
views of one section. Ranges that are adjacent in guest address can be
separate views, so the refusal escaped from importAllocation and
agc_driver_dcc_keys_first_write failed on main with "read-write alias
of shared guest memory ...: the range is not one contiguous run of
views of a section".
A span whose alias is refused is now remembered, and its ranges are
imported one at a time as before spans; a single range that is refused
still throws.

With the f32 denormal field of FLOAT_MODE set to keep, v_ldexp_f32
flushed subnormal inputs and results to zero. Keep subnormal inputs and
round a result that lands in the subnormal range in the f32 round mode
of FLOAT_MODE. An overflow follows the round mode as well, with or
without denormals kept: the largest finite value instead of infinity
when the mode rounds that sign toward zero. This matches RDNA2
(gfx1036) on 2163 rows in each round mode. Denormal modes 1 and 2 now
throw.

The bundled libc.prx of PPSA21703 calls sceKernelGetModuleInfoFromAddr
with a 0x1A8-byte stack buffer and never sets st_size, so the field holds
whatever was on the stack (983040 in one run) and the call threw. The
console cannot require the field on input. The full size is still
written back. The flags check is unchanged.

Retain the original WAIT_REG_MEM fix from #2985 and resolve its test-registration conflict with main d7cfa728. Preserve both upstream test blocks and the original commit ancestry.
Local conventions and whitespace checks pass. Windows/GPU results cited in issue #2832 belong to their reporting contributors. No local GPU execution.
DT_SCE_STRTAB, DT_SCE_SYMTAB, DT_SCE_RELA and DT_SCE_JMPREL are offsets
into the PT_SCE_DYNLIBDATA segment, as the code analysis and the guest
image reader already read them, but the pipeline read them as file
offsets. That only works when the segment starts at file offset 0, as in
the test fixtures. A PS4 executable (CUSA00900) keeps the segment at
0x53e9b40, so the relinker read its relocations from the code and failed
with "Dynamic string offset is outside DT_STRSZ". Without the segment the
values are still read as file offsets.

A plain image_sample that says DIM 2D on a 1D T# takes its texel and its LOD
from the first coordinate alone, measured on RDNA2 (gfx1036) with the
hardware oracle. Astro's Playroom draws with such a pair.
DB_ALPHA_TO_MASK 0xaa01, the enable bit with the four offsets at 2 and no OFFSET_ROUND, reaches the pixel stage, which keeps a pixel when its MRT0 alpha is at least one half. Dithered or rounded settings, and an MRT0 that is missing, swizzled, packed or exported without a floating-point alpha, still throw. God of War Sons of Sparta (PPSA28997) stopped on it a few minutes into play.
The AMM ranges were reserved address-less on first use, so they took the
lowest free address of the arena, directly after the title's last mapping,
where the title's next hinted maps go. They are now reserved at a fixed
place, the last 64 GiB of the guest arena, which maps without MAP_FIXED and
the hints derived from them do not reach; a reservation that cannot be made
there throws.

The POSIX alias takes (attr, int), returns EINVAL (22) for a null or
uninitialized attribute like the other pthread_attr setters, and
stores the value through scePthreadAttrSetsolosched, returning its
result in errno form. The signature and the stored int follow the SCE
twin in KytyPS5 and sharpemu; PS5PCEM implements the alias the same
way. The value is not applied to scheduling, recorded in TechnicalDebt.

#2839 decides f32 product tininess after rounding, in all four f32
round modes, from the exponents and a UMulHi and IMul of the
significands, and builds the flushed value from them. To nearest even,
the mode of shaders without a known float mode and of the 0xc0 most
titles use, one multiply decides it: one factor times 2^64, which is
exact below 2^64, times the other factor rounds the exact product once
to 24 bits in the normal range, and 0 < |that| < 2^-62 is tininess
after rounding. A product that rounds up to 2^-126 is then not tiny and
keeps the emitted product, which is 2^-126 there, so nothing has to be
built from the significands.
The flush of v_mul_f32 v5, v6, v7 takes 12 IR instructions instead of
34, counted as the instructions the flush select needs beyond the
product. vector_constant_factor_tininess pins 12 to nearest and 36 for
the directed path of the same instruction, and checks that the
directed modes and v_mad_legacy_f32 (before rounding) keep #2839's
check. Its round-to-nearest branches are removed as unreachable.
The f32 denormals entry says which rounding the check inherits: the
multiply is a plain OpFMul like the product, with no f32 rounding mode
requested, so it relies on the driver rounding f32 to nearest even, as
the products do. F32ConstantFactorTininess names the row a check before
rounding flushes, 0x3f7ffffe * 0x00800001, which keeps the emitted
0x00800000.
Against #2839 to nearest even, a model of both checks agrees on
1,074,977,546 operand pairs (every 24-bit significand at both rounding
thresholds, random pairs, specials) with each other and with an exact
reference. On an RTX 5070 the outputs of #2839's own tininess and
mixed-source shaders are bit-identical with either lowering over
165,298 and 164,008 generated rows in all six float modes tested.

A wait on an equeue that holds socket events now blocks in poll/WSAPoll on
those sockets plus a per-thread loopback wake socket, instead of rechecking
every millisecond. Adding, triggering or deleting an event and closing the
equeue wake the blocked waiters. Closing a socket removes its read and write
events, as on FreeBSD. A read event also reports EV_EOF once the peer has
shut down its sending side.
sceKernelAddReadEvent/DeleteReadEvent and sceKernelAddWriteEvent/
DeleteWriteEvent register EVFILT_READ and EVFILT_WRITE events on guest
sockets. The equeue polls the host socket for readiness on each wait
and reports the readable byte count or the send buffer size in data,
with EV_EOF on hang-up or error.
sceVideoOutVrrPegToFixedRate and sceVideoOutVrrUnpegFromFixedRate were
NotImplemented without arguments. Both take the output handle; the peg
also takes two further arguments whose meaning is unknown. VRR is not
modelled and the output always runs at a fixed rate, so both validate
the handle and return 0; non-zero peg arguments throw. Recorded in
TechnicalDebt.
Uncharted: Legacy of Thieves Collection (PPSA05684) stops on main with
"sceVideoOutVrrUnpegFromFixedRate not implemented"; it passes its
output handle to both (and zeros to the peg) and ignores the results.
Since #2133, a 3D image_sample_lz or image_load bound to a 2D-array T#
decodes as 2D and matches the new 2D mode, so it reads layer 0 for any
r and returns zero for z != 0. adriadam10 measured on RDNA2 (gfx1035)
that dim 3D on a 2D-array T# behaves exactly like dim 2D-array, with r
or z as the layer. Decode a 2D-array T# bound to a 3D access as 2D-array
and add a 2D-array mode next to the 2D one.
The same measurement covers image_load_mip on both T# types and
image_get_resinfo, which returns (w, h, 1, levels) on a 2D T# and
(w, h, layers, levels) on a 2D-array T#. Allow those accesses and return
1 as the third resinfo component through the 2D mode. image_get_lod is
not measured and keeps throwing.
Key 0x10 (GFX9_DCC_CLEAR_SINGLE in Mesa) marks a 256-byte block whose texels all equal its first texel. A CB DCC decompress pass over uniform comp-to-single keys now writes that texel over its block and stores uncompressed keys; a fast-clear eliminate over them throws.
v_log_f16 is lowered through the same f32 log2, so the entry names both
and states the f16 effect measured over every f16 input (one NVIDIA
result moves onto the hardware's bits, none on RADV). The series is
chosen with OpSelect, so its cost applies to every v_log.

The driver's Log2 has an absolute error that does not shrink with the
result, so near 1.0 the relative error explodes: on an RTX 3080, v_log_f32
of 1 - 2^-24 is 23,947,836 ULP off. Measured on RDNA2 (gfx1036), the
hardware's log2 is within 1 ULP of the correctly rounded value, and an
eight-term series in x - 1 is within 2 ULP of both for |x - 1| <= 1/8.
The lowering keeps the driver's Log2 and takes the series only inside that
band when the two differ by more than 4 ULP, so RADV's native result stays
bit-exact and NVIDIA's is within 6 ULP inside the band.
agc_driver_log_near_one pins 64 inputs per type from the oracle with
per-lane tolerances.
