XSAVEOPT raises an illegal instruction under Rosetta on an M5 running
macOS 27.0.1, as XSAVEC does, while XSAVE and XRSTOR save and restore
x87, SSE and AVX state in the standard format. The PS5's Zen 2 has
XSAVEOPT, so code built for it can use the instruction without a CPUID
check.
XSAVEOPT differs from XSAVE only in the init and modified optimizations:
it may skip writing state that is in its initial configuration or
unchanged since the last XRSTOR from the same area. XRSTOR restores the
same state from the area XSAVE writes, so --to-rosetta rewrites
XSAVEOPT (NP 0F AE /6, memory operand) to XSAVE (/4) in place, keeping
the prefixes and the operand, as RDSEED becomes RDRAND. CLWB (66 0F AE
/6), MFENCE, UMONITOR, UMWAIT and the Intel target are left alone.
XSAVEC is not converted: it writes the compacted format.
The converter tests check the rewrite for the plain, REX.W,
RSP-relative, extended-base, RIP-relative and FS-relative forms, check
that the neighbouring 0F AE encodings are not taken, and execute the
rewritten XSAVEOPT64 followed by XRSTOR on YMM3 in the x86-64 build.
The --to-rosetta integration test now covers XSAVEOPT as well.
Forward new-image recovery permission through AllocateImageMemory while preserving host-memory fallback and allocated-type reporting. Reuse held cache locks only at safe construction points, retain caller-held sampled textures and pending storage results, and try resource-cache removal without waiting.
Count released Vulkan allocations and saturate the reclaim reserve. Cover sampled/storage allocation failures, host fallback after image recovery, bounded attempts and overflow. Remove stale conflict markers and unrelated debt, and refresh the recorded validation.
The debt entry no longer says that a leaf with an rsp operand that
cannot move in place is skipped. A new entry says that such an operand
moves to a stub, when the leaf is still skipped, and that a game patch
over a framed site or a moved displacement is refused. The USAGE row
says the same in short.
The second half of a pipelined draw (stage materialization, cache insert,
enqueue) runs on a finisher thread, overlapping the next draw's packet
work; draws whose stages could write memory are held back. Commits skip
work whose inputs did not change since the last commit, color metadata
passes are ordered through the pipeline, resource and storage-image proofs
are reused within one collect epoch until a write breaks them, and a shape
entry is refreshed in place at the second sight of the same read user words.
APS5_VERIFY_DRAW_PIPELINE checks reused proofs against a full check.

On Windows, dlopen passed a module that was never relinked to LoadLibraryExW, which raised the
modal Bad Image hard-error dialog and blocked the calling thread until someone answered it. The
load now runs with SEM_FAILCRITICALERRORS set for that thread only, so it fails at once with the
same result as before. Every failed load is reported once per file on stderr with a [module]
prefix; a file that exists with no relinked .guest.prx names the relinker's --module-dir option.
On Linux sceKernelGetdirentries copied the host d_type, so a directory under app0 that is a host symlink was listed as a link, and a title that only descends into directory entries skipped it. Inside the app0 tree, report a symlink (or an entry of unknown type) as the type of its target; links elsewhere, and dangling links, stay links.
Some titles wait for a chord on their title screen: RollerCoaster Tycoon
Adventures Deluxe (PPSA17330) asks for L1 + R1. The command file already
carries a button bit field, but the helper accepted one name. Names joined
by '+' are now combined into one command; unknown names, duplicates and
release in a chord are rejected without touching the command file.

The crash and abort reports printed the last 64 traced calls of the whole
process, so a thread that loops on a traced import (a mutex lock/unlock
pair, a profiler marker) pushes the calls of the faulting thread out of the
report. The ring already keeps the last 65536 calls with their thread.
CopyThreadCallTrace_nid_no_patch returns the most recent calls of one
thread from that ring, oldest first, and both reports (Windows crash and
abort, Linux abort) list up to 32 of them for the reporting thread after
the process-wide list.

StorageTextureBudget reserved the larger of the sampled textures alive
and their 2 GiB floor. The sampled budget already reserves
TextureCacheBudget, at least the storage cap, for the storage cache, so
on an 8 GB card the two caches each kept the other's maximum: with
3936 MiB used outside the caches on a 7189 MiB budget and 49 MiB of
sampled textures, the storage budget came out at 306 MiB and sat at its
512 MiB floor while about 2.7 GB of the budget stayed free.
The storage budget now reserves the sampled textures alive and gives
room back as they grow, at its next read. Where they hold 2 GiB or more
the budget is unchanged.
F12 (the new Screenshot input action) requests a capture of the next
presented display buffer. The presenter records it with the existing
APS5_DUMP_FRAMES GPU readback at full resolution, and the frame dump
writer thread encodes it with decoder_png into anyps5-screenshots/
beside the executable, or ANYPS5_SCREENSHOTS.
A --module-dir module that only the executable needs was initialized by
the Windows entry stub with no start arguments, so a later
sceKernelLoadStartModule with arguments found it started and its
module_start never saw them. Unity's mono-ps4.sprx keeps those
arguments for the plugins it loads. Such a module is now deferred like
any other runtime module: mapped at startup and started, with its
arguments, when the title loads it. Modules another guest module needs
are still started at startup, and Linux and macOS are unchanged.

The Linux entry stub now passes each traced import through libc.prx's
TraceImport_nid_no_patch before it calls the guest entry, and stores the
returned thunk in the import's slot. The same imports are traced as on
Windows: functions bound through a PLT slot or a GOT slot, without an
addend, and not weak. TraceImport_nid_no_patch is bound eagerly through
an added GLOB_DAT relocation, so a libc.prx without it fails at load.
Each slot's page is made writable with mprotect first, so slots inside a
PT_GNU_RELRO range can be replaced.
--trace-imports now requires libc.prx among the libraries on Linux too,
and is refused with --macos.
