Keep logical sample and skip counts across byte-only continuation buffers, assemble split superframes, and allow callbacks to refill, pause or reset the stream. Preserve decoded audio while waiting for input and reject truncated closed streams.
Validated with seven NGS2 tests, an ASan/UBSan streaming test build, and PPSA03747 repeatedly supplying continuation buffers during playback. Flag semantics follow the pinned KytyPS5 source documented in TechnicalDebt.md.
Written with AI assistance.
The named VRR functions hash to LibwuIonIBw and kP2L8t3j-aM already.
Their explicit aliases therefore create second PE exports with the same
patched NIDs and prevent Windows builds from completing.
Keep the named function exports and remove their redundant aliases.
The NID patcher's duplicate-export validation remains unchanged.
Scan version stamps within contiguous leaves. On Linux, collect nearby
pages within queue epochs only after confirming full watched coverage.
Keep the requested range on Windows. Select the range before collection
and do not retry a failed walk.
Test sparse-leaf boundaries, write histories, partial unwatches and epochs.
Fedora 44 Release tests pass with default, disabled and shared caching.
Isolated upstream comparison reduces the saved collect replay by 11-12%.
Windows was not tested.

EVO-PLAYER (PPSA99039) v0.11.0 stops at sigaction once its earlier
imports resolve: it installs a crash handler for SIGSEGV, SIGBUS and
SIGABRT and a quit handler for SIGTERM, SIGINT and SIGHUP at start-up.
sigaction records the handler, flags and mask of signals 1 to 128 and
reports them back, with FreeBSD's EINVAL cases. signal shares the table
and records SA_RESTART, as FreeBSD's libc does. Plain handlers on the
signals signal already delivers run as signal handlers do; SA_SIGINFO
handlers and other signals are recorded only, and raise of such a
signal throws.

The entry stubs called the title's entry with rbp left as the process
started it (0 on Linux) or as a loop counter left it (0 on Windows). The
title's start code pushes rbp, so the frame-pointer chain of its main
thread ended in a null frame pointer. Unreal Engine walks that chain to
capture call stacks (for an ensure, for example) and reads the return
address at [rbp + 8], so the walk read address 8 and crashed.
Both stubs now push a zero frame record (saved rbp 0, return address 0)
and point rbp at it before the call, so frame-pointer walks stop at the
entry. The Linux stub pushes it below the aligned stack pointer, keeping
the 16-byte alignment at the call. The Windows stub writes it into free
slots of its own frame at rsp+0x40.
PPSA15657 crashed in its stack walk at the title screen in about half of
its runs.

On Linux, shared direct memory is imported through /dev/udmabuf (#943).
Many distributions create it as root:kvm 0660, so a user outside the
kvm group cannot open it. The ranges are then copied instead of
imported, and GPU stores through FLAT/GLOBAL addresses to them fail
with "BDA access failed": DOOM PPSA99666's compute presenter falls back
to its CPU scaler. The only trace was "failed at open /dev/udmabuf
(-1000072003)", a Vulkan result that hides errno.
Print the open error once, with the fix for EACCES, and document the
requirement in USAGE.md.

With OOB_SELECT 0 and stride 0 every access is out of range now that the
buffer bounds follow OOB_SELECT, so the shader never read or wrote.

A subnormal operand sent v_fma_f64 to a separate multiply and add, and a
subnormal result was rounded twice: once to 53 bits in the scaled domain
and again by the power-of-two rescale. Both differ from IEEE 754
fusedMultiplyAdd in the last bit.
Subnormal operands are now widened by 2^64 and enter the exact path with
their exponent lowered by 64. The exact path keeps the sign of the residual
between the 53-bit result and the exact sum; when the result lands on a
midpoint of the subnormal grid it is moved one ulp towards the exact sum
before the single final rounding. Normal results are rebuilt by setting
the exponent, so only a subnormal result rounds. v_div_fmas_f64 shares the
path.
Each Windows AIO request is an overlapped ReadFile/WriteFile at the
request's offset, which on a synchronous handle also moves the
descriptor's file pointer; on the console AIO transfers leave it alone.
The requests now go through the positioned path sceKernelPread and
sceKernelPwrite use (NativePositioned in Stdio.cpp, exposed as
NativePositioned_nid_no_patch), which restores the pointer afterwards.
Negative offsets still fail with EINVAL before the transfer.
GuestAio sets the offset to 2 before a write batch and checks it is
still 2 after. TechnicalDebt records that a concurrent read or write on
the same descriptor can see the moved pointer in between, as for the
pread family.

Install lavapipe on Linux release builds and set ANYPS5_REQUIRE_VULKAN and GALLIUM_OVERRIDE_CPU_CAPS for ctest so GPU execution tests run instead of skipping. Scope SSL_CERT_FILE to Windows winlibs download and CMake configure steps only so Linux FFmpeg fetch is not broken. Leave release ctest as a single strict run.
A use of the packed ancillary VGPR other than a constant field extract (the word passed through a
select before its sample number is extracted) reads the word rebuilt from the sample number (bit 8)
and the render target index (bit 16). Extracts of other bits straight from the word stay refused, and
the refusal now names the uses.
