Henrik RydgårdandClaude Opus 5.5 1467ef24a7 GL: Report readback failure, and convert from the format actually read
CopyFramebufferToMemory always returned true, even when glReadPixels
failed, and then copied out whatever the readback buffer held from before.
Depth was labeled D24_S8 while GL reads it as float, and the conversion
ignored the source format, so only a D32F destination came out right.

Record the format and the result of each read, convert from that, and
return it. That also fixes the image readback reusing the aspect of an
earlier framebuffer readback.

Henrik RydgårdandClaude Opus 5.5 f04d99e952 Vulkan: Reject a delayed readback of the backbuffer
The backbuffer is a different image every frame, so there's no earlier copy
of it to return, and the lookup fell through to the sync readback buffer.

Henrik RydgårdandClaude Opus 5.5 d15e094ed6 Vulkan: Key delayed readbacks by position and aspect too
The OLD_DATA_OK readback cache was keyed by framebuffer and size only, so
two equal-size rects of one framebuffer shared a buffer and each read got
whichever was copied last. Add x, y and the aspect to the key.

Henrik RydgårdandClaude Opus 5.5 ecad07b3b1 D3D11: Fix readback of a rectangle that doesn't start at the origin
Without the shared 512x512 pack texture, the staging texture was made
bw x bh, but the copy lands at bx, by and the read starts there. Depth and
stencil were worse: CopyResource needs the whole size, so nothing was
copied, and the read ran past the end of the mapping and crashed. Only
whole-buffer reads from 0,0 (like the debugger's) worked.

Vulkan: Preserve active frame profiling queries when stopping threads
2026-10-12 11:48:46 +02:00
Eray Cepni 4158f114d0 Vulkan: Preserve active frame profiling queries when stopping threads
StopThreads is called inside the
FramebufferManagerCommon::NotifyRenderResized. Issue is, StopThreads is
called inside an active frame, then clears that active frame's timestamp
descriptions. Rendering resumes, and QueueRunner uses the empty list’s
size to select query 0, which was already written.

Fix this by preserving timestamp descriptions for the current frame
when insideFrame_ is true while retaining the cleanup for other frames.

pspKeys and pspAxis were written from the input thread and the render
thread without a lock. Entering VR camera adjust "released" held keys by
sending PSP button codes as keycodes, which released nothing; use
ControlMapper::ReleaseAll instead.

Input devices are now matched by ID. InputDevice objects are replaced after
device changes, so reference comparison registered the same device again.

Henrik RydgårdandClaude Opus 5.5 e2cda3d8f0 UI: Forget the views' pending requests when recreating them
WipeRequesterToken() only reset the screen's token, after CreateViews() had
already handed it to the new views, so nothing was ever forgotten - not even
in ~Screen(), which saw a token of -1. A text input dialog open across a
RecreateViews() (on the RetroAchievements screen, a slow login failing) would
then write through a deleted PopupTextInputChoice, possibly into the field
that took its place: #21708.

Requests made while creating views now get their own token, forgotten
before the views are deleted. Screen-level requests keep the screen's token.

RequestManager: ForgetRequestsWithToken() now locks, and also drops
responses that arrived but weren't processed yet. ProcessRequests() calls
the callbacks one at a time without holding the lock, so a callback that
closes a screen drops the rest of that screen's responses.

Since db8ff43, a leftover local shadowed lastImguiEnabled_ in runImDebugger,
so TEXT_GOTFOCUS was never sent and SDL never started text input for imgui.
Drive it from io.WantTextInput instead, so it's only on while editing.

The regular UI and the debugger now say independently whether they want text
input, and the platform only gets TEXT_LOSTFOCUS once neither does, so leaving
an imgui field doesn't break type-to-search on the screen underneath.

Henrik RydgårdandClaude Opus 5.5 9f1278b5d6 iOS: Link MoltenVK statically in sideload builds too, raise target to 15.0
Sideload builds used to dlopen a bundled libMoltenVK.dylib, which was
only worth having while they could still fall back to OpenGL. Now both
variants link the static MoltenVK from ios/MoltenVK and call Vulkan
directly. PPSSPP_VK_STATIC replaces the IOS_APP_STORE checks in the
Vulkan loader (the iOS libretro core still loads at runtime).

The static MoltenVK needs iOS 15.0, so that's now the deployment target
for all iOS builds.

JIT shadow block map: Keep JIT block entries and replacement hooks out of PSP memory
2026-10-11 12:46:42 +02:00

Fixes #22497
2026-10-11 10:56:43 +02:00
Henrik RydgårdandClaude Opus 5.5 6d122f416e Keep JIT block entries and replacement hooks out of PSP memory
The JITs used to find a block by overwriting its first instruction with an "emuhack" holding
the offset into the code space, and replacement functions installed their own emuhack the same
way. Anything that read code (savestates, the debugger, memory dumps, cheats, the function
hasher, games reading their own code) had to translate them back.

Blocks now live in a block shadow: one u32 per guest instruction, indexed by the PC masked with
BLOCK_SHADOW_MASK (1GB on 64-bit, folding the kernel and uncached mirrors; 256MB on 32-bit, iOS
and Switch, where address space is short), with the low bits cleared so a misaligned PC can't
read across two entries. Only the ranges under memory views are committed, so a bad PC still
faults in the dispatcher, and the shadow is reserved before the memory map so it can't land in
a gap of the 4GB window. Entries hold full 32-bit offsets, lifting the 16MB limit. The
dispatchers on every backend, and the IR interpreter's loop, look blocks up there.

A hooked instruction without a compiled block gets the JIT's hook value in its entry: the offset
of the dispatcher's compile path (1 for the interpreters, the IR arena keeping that offset
empty), so dispatching there compiles a block, and the frontends substitute the hook. Compiling
replaces the entry with the block's, and destroying the block puts the hook value back. The hook
value is rewritten when the JIT changes or regenerates its dispatcher.

Hooks live in a map keyed by the masked address, and are dropped when the game overwrites the
hooked instruction, or when an icache invalidation finds the function's hash (immediates masked,
as when matching it) changed. Those checks run when queued invalidations are processed, since
cheats and the debugger queue them before writing. Installing and removing hooks invalidates
deferred, as it happens in HLE calls that can run inside a block. The cache instruction goes
through MIPSState, so it drops changed hooks too.

With clean memory, the save/clear/restore around savestates, memory reads and dumps goes away,
as do the source-range invalidations in the memcpy replacements, sceDmac and the cheats.

Henrik RydgårdandClaude Opus 5.5 6cf4872e78 Android: Hand microphone input over on the CPU thread, like the other hosts
The Oboe input callback used to call Microphone::addAudioData directly,
writing PSP memory from the audio thread. Now it only pushes samples
into a SampleRing, and pollRecording drains it on the CPU thread.
Starting and stopping still go through Java, which asks for permission.

Every host with a microphone polls now, so sceUsbMic drops what only the
push path needed: QueueBuf's recursive mutex, restarting the mic on a
device change, and the startMic parameter nobody read. Also removes the
unused System_AudioRecordingState and Microphone::isNeedInput.

The Java microphone_command branch didn't return true, so every command
logged "processCommand failed".

Henrik RydgårdandClaude Opus 5.5 b4ec29111b Microphone: Let the host say whether it wants polling, rather than checking for SDL
The CPU-thread polling added for SDL was keyed off defined(SDL), which
headless and Core are built with too, hence the extra headless check.
Ask the host instead, with SYSPROP_MICROPHONE_NEEDS_POLLING, so other
hosts can hand their input over the same way.

startMic now sends the same startRecording command for every non-Win32
host, taking the rate from curSampleRate like the SDL path did. The
Android path read it from param, which leaked, and which is null when
coming from onMicDeviceChange.

Henrik RydgårdandClaude Opus 5.5 16a5046124 SoftGPU: Read bilinear CLUT and 8888 texels in vector lanes
The four-pixel bilinear sampler read its sixteen texels one at a time,
each with its CLUT lookup and index transform, and loaded them as
vectors afterwards. For CLUT4 and CLUT8 with a 32-bit palette and no
index shift (by far the most common), and for 8888, the texels are now
gathered in lanes: the index bytes, the nibble, the mask and start, then
the palette entries. CrossSIMD gets Vec4S32::Gather and GatherU8 for it,
one load per lane. LocoRoco executes 5.5% fewer instructions, Burnout 3%.

Henrik RydgårdandClaude Opus 5.5 f02936575d SoftGPU: Multiply small lane values with 16-bit multiplies
SSE2 has no 32-bit lane multiply, so Vec4S32::Mul is emulated with two
pmuludq and shuffles, and the bilinear sampler spent a tenth of its time
there. The texel row offsets, the texture functions, fog and blending
only multiply values that fit 16 bits, which Mul16 does in one pmaddwd.
The bilinear lerp of two channels packed as 16-bit halves uses the new
MulHalves (pmullw), which multiplies both at once.

without memory. Wipeout runs about 2% faster.

ReadVertex took the GE's viewport arithmetic one coordinate at a time,

the whole vertex in pieces that were then reloaded with wider loads,
each a store forwarding stall. x, y and z now go through one GERecip and
the four-lane multiply and add (the scalar path stays for non-finite
input and zero or denormal w), the position is loaded as a vector, and
the vertex is written straight into its destination.

MoltenVK doesn't support a sampler mipLodBias (the portability subset's

Cars Race-O-Rama and MX vs ATV Reflex recreate framebuffers every few frames,

their brightness adaptation went wrong on GL. Now GL reads the same values as

The fallback (which RISC-V uses) did its integer arithmetic in plain int,
where signed overflow and left shifts of negative values are undefined,
and converted out of range floats with a cast, which is undefined too:
RISC-V gives INT_MAX for NaN where SSE gives INT_MIN and NEON 0. With GCC
on RISC-V that broke GEUVSpanCore in the GEMath unit test. Now the
arithmetic wraps through uint32_t, like the SIMD instructions, and an out
of range or NaN conversion gives INT_MIN, like SSE.

Also skip GERowSum's zero terms before computing their shift, as their
exponent can be INT_MIN. Found with -fsanitize=undefined on the fallback.

Henrik RydgårdandClaude Opus 5.5 d0baab5614 Compute FIXA/FIXB blends like the GE
The GE's blend terms are floor((2c+1)(2f+1)/1024), which truncates, while the
hardware multiplies by f/255 and rounds, so every pass of a fixed color blend
chain came out up to a level brighter. God Eater Burst's bloom is many such
passes and ended up far too bright.

For additive FIXA/FIXB blends that aren't just 0 and 0xFFFFFF, the shader
now computes the src term exactly and lowers it by 0.5 - (2B+1)/1024, and the
blend constant is the GE's dst factor (2B+1)/512, so the hardware's rounding
of the sum lands on the GE's floor (except where the src term would go below
zero). Blend constants are passed as floats to make that possible.

The four clip space rows of a vertex, the texture matrix's three, the world
normal's three, the vector to a light, and each row of the combined matrix
now take one GERowSum4 call. Same results (pspautotests, frametests and
the probe regression set unchanged).

GERowSum4 scales its result by adding to the exponent instead of
multiplying, and CrossSIMD gets a Vec4S32::Max for the largest lsb. About
68 M transforms/s against 26 for four scalar GERowSums on an M1 (a pure
NEON version with per-lane shifts did about 79); replaying the frametest
dumps gets only about 1% faster, up to 11% on Taiko no Tatsujin.
