14 of the 15 upstream commits since bab81aa23. The fifteenth, 3aea3b15d 'Fix
ISO timestamps', is deliberately left out: it touches rpcs3/Loader/ISO.cpp,
and the Aug-2026 upstream ISO refactor is already reverted here because it
breaks some images (region_count reads 0 and the disc will not mount). It is
the tip commit, so merging its parent excluded it exactly, with no surgery.
Four conflicts, all of them ours-and-theirs rather than either-or:
nv4097.cpp conflicted whole-file. Took ours and applied upstream 071c9f10f's
set_shading_mode by hand -- an earlier merge of this same file lost two hunks
by resolving it wholesale, and that is recorded in c6a0878a9.
VKPipelineCompiler.cpp: ours has the mobile dynamic-state work (topology-class
collapsing, normalize_dynamic_pipeline_state, compiler thread affinity),
upstream adds a provoking-vertex chain for flat shading. They are independent,
so both are in, with the rasterization state rebased as upstream needs.
device.cpp: three hunks, all parallel feature queries -- extended dynamic
state and the Android LSFG feature bits on our side, provoking vertex on
theirs. All kept; ours' extension push needed its own closing brace.
BUILDING.md stays deleted: 30fc4e566 folded it into the README, and upstream
merely edited it.
Core builds and links.
The keyboard setting, the on-screen keyboard hotkey, the touch button and the
IME plumbing all worked. Nothing behind them did, in three separate places:
- init_kb_handler installed NullKeyboardHandler unconditionally, so cellKb --
the API games actually read a keyboard through -- reported none attached no
matter what the UI said.
- NativeApp.usbKeyboardKey and usbSetKeyboardEnabled were Unsupported.note()
stubs. Every keystroke went into a no-op that returned false.
- The setting wrote [USB1] Type = hidkbd, which is PCSX2's emulated USB HID
keyboard. There is no such device in this core -- "hidkbd" appears nowhere
in it -- so that write only ever reached Unsupported.note("USB1/Type").
All three are inherited from the UI port, which is why the feature looked whole.
The desktop handler is a QObject that installs an event filter on a QWindow, so
none of it survives the port. It does not need to: everything that turns a key
into cellKb data already lives in KeyboardHandlerBase::HandleKey, and a concrete
handler owes it exactly one thing, a populated qt_code -> CELL_KEYC map.
virtual_keyboard_handler builds that map with the Qt key codes as literals, and
translates Android keycodes onto it -- including left/right modifiers, which have
to come back in the native_key encoding get_out_key_code compares against or
every modifier reads as the right-hand one.
The setting now writes Input/Output/Keyboard, which is what the core reads. That
happens once, in Emulator::Load, so it applies on the next boot rather than to a
game already running; the description says so now, because the old comment
claimed a live attach that never existed.
KeyEvent.getUnicodeChar() is carried through as well. cellKb derives its own
character from the raw code plus the live modifier state and does not need it,
but the emulator's own overlay text entry matches on the string.
Adds an Android build of the RPCS3 core plus a Compose UI, and fixes several
things that stopped it working on ARM64.
Renderer:
- Emit concrete bounds for runtime sized arrays in uniform blocks when
VK_EXT_shader_uniform_buffer_unsized_array is missing. Adreno does not have
the extension, so every game pipeline failed with VK_ERROR_UNKNOWN and only
overlays drew.
- Probe and request that extension properly instead of chaining its feature
struct unconditionally.
- Hand VMA the Vulkan function pointers it needs under VK_NO_PROTOTYPES.
- Rebuild the surface and swapchain when the window is lost instead of killing
the RSX thread.
- Only create a GLES context when the GL renderer is actually selected.
SPU:
- Sum instead of taking an absolute difference in the ARM64 block verification
checksum. The difference collides on the near identical job binaries an SPU
job manager streams through one local store address, so a cached block could
run against another job's code.
Threading:
- Implement thread affinity on Android using sched_setaffinity.
- Add an ARM big.LITTLE core arrangement so SPU and RSX threads land on the
fast cores.
Misc:
- Detect the host CPU for the LLVM JIT instead of pinning cortex-a34.
- Fall back to the default audio device when cubeb cannot enumerate.
This is a continuation of my work on #18113.
Addresses issue #18197.
Adds a new checkbox in the I/O settings tab that enables mouse-based
gyro emulation at game startup, making the feature more discoverable to
users.
