After an exact two-piece join, a bind across the join's end got the
joined import from importAllocation and the view failed as "rounded up to
its view range exceeds its GPU owner". UploadFinish now asks importJoined
for a region past the import's end and drops an import that still does
not cover the region, so the region is copied, as on main. The join test
binds across the end of an exact join after a third piece is registered.

A bound buffer is joined across adjacent registered ranges only when every
one of them is larger than the 8 MiB window. PPSA25344's loading binds 16 MiB
and 4 MiB buffers whose backing was registered in two to six adjacent
pieces with the same access, some of them smaller than the window, so each
use of such a buffer was copied on the CPU: up to 348 GB in the first 300 s
of loading.
A bound buffer that starts at the first crossed range's start and ends at the
last one's end now joins those ranges whatever their size. A heap grown in
pieces matches that only for a binding over exactly its current pieces, so
growth beside a joined import does not re-import it. joinedCovers, used when a
joined import retires, accepts any adjacent run of ranges.
importJoinTests binds exactly over two 64 KiB pieces of a partly filled
window and requires one import of both; a binding across them that starts
inside the first piece stays apart.

Read the optional aligned budget from param.json and apply it consistently to configured, available and mapped flexible memory. Add parser and allocation regression coverage.
The 9-word kernel #3816 matches stores one dword per thread, loaded with
s_buffer_load_dword through the descriptor in user[4..7]. Run as a
compute dispatch, its stores are pending writes of unknown value, so a
later read of DCC keys in that range waits for the GPU.
fillBuffer now takes it as a uniform buffer fill when all of these hold:
- the output descriptor's format is 32_UINT, 32_SINT or 32_FLOAT (20-22),
so buffer_store_format_x stores the loaded dword unchanged;
- the value descriptor covers the loaded dword: num_records times the
stride (num_records alone when the stride is 0) is at least 4 bytes,
the range the recompiler gives a scalar buffer load;
- exactly 8 user SGPRs and group id X enabled, so the group id is s8;
- a direct, non-partial dispatch, 64x1x1 threads, one group in Y and Z,
and a 16-byte aligned range of whole 16-byte units.
The value is read when the fill is recorded, after the labels queued
before it, as the pattern-fill kernel's source is. When the value is one
byte repeated and that byte is a DCC key code, the fill goes into the GPU
key-store memo whatever ClassifyFill reports: the memo answers a key
read only while this fill is still the newest pending write over the
keys, and a fill over a color target's keys is not a storage image's
keys fill.

The per-descriptor lock exists only in the Windows transfer path, so ShareDescriptor calls SharePositionedTransfer under _WIN32 like GuestFileLockShare. Linux failed to link libkernel with an undefined reference to it.
swscanf (HNnWdT43ues) runs the swscanf_s scanner without the buffer
size arguments after %s, %c and %[, as FreeBSD's swscanf.c passes its
arguments to vswscanf. Both entry points share one engine with a flag
for the sizes; swscanf_s behaves as before.
Title: PS5CEMU-HAR PPSA99360 imports swscanf from libSceLibcInternal.prx
(import audit with --trap-sdk-syscall-stubs, registry index 292, right
after pthread_setaffinity_np at 276). Predicted stop line once
pthread_setaffinity_np resolves, without this change:
FAIL: unresolved ELF import HNnWdT43ues (swscanf) from libSceLibcInternal.prx
NID from tools/nid_names.py, confirmed in shadPS4 aerolib.inl:51950
(e0a466753a1a). Prototype in ps5-payload-dev include/freebsd/wchar.h:133,
export in sce_stubs/libSceLibcInternal.c:8582 (f5d40f02770e).
