# Phase 1.0A build and artifact results
|
||||
|
||||
## Result
|
||||
|
||||
`RETROARCH_PS5_SOFTWARE_PORT_BUILT`
|
||||
|
||||
Both outputs are real RetroArch v1.22.2 frontends built from fork commit
|
||||
`ca1b45680577befc743e1c92fa40687e1b1745e7`. They link the upstream
|
||||
frontend/runloop and the static `chimera_smokecore`; the software target also
|
||||
links RGUI and the reviewed PS5 SDL2 software backends. They were not run.
|
||||
|
||||
| Profile | Local output | Size | SHA-256 | Map SHA-256 |
|
||||
| --- | --- | ---: | --- | --- |
|
||||

|
||||
|
||||
The paths are relative to the separate `chimera-retroarch` repository. The
|
||||
ELFs and maps are ignored local build outputs, not files in `chimera-gfx` and
|
||||
not transfer, execution or installation packages.
|
||||
|
||||
## Builds and reproducibility
|
||||
|
||||
Every target comparison used fork commit
|
||||
`ca1b45680577befc743e1c92fa40687e1b1745e7`, SDK commit
|
||||
`d2e2e585740362976a39fdd5ccf390f199a7bc37`,
|
||||
`SOURCE_DATE_EPOCH=1763597828`, `TZ=UTC` and `LC_ALL=C`.
|
||||
Each repetition invoked `make ... clean` to completion before a separate
|
||||
`make ... -j4 all`. An earlier concurrent `make clean all` experiment was
|
||||
rejected as a race and is not evidence.
|
||||
|
||||
| Comparison | ELF | Linker map |
|
||||
| --- | --- | --- |
|
||||
| headless A versus B | byte-identical | byte-identical |
|
||||
| software A versus B | byte-identical | byte-identical |
|
||||
|
||||
Compiler flags include warnings-as-errors, `-O2`, no debug data, source-prefix
|
||||
maps, section garbage collection, `--as-needed` and `--build-id=none`. The
|
||||
cross compiler reports Clang 18.1.8 for `x86_64-sie-ps5`; GNU Make 4.4.1 was
|
||||
used under WSL2.
|
||||
|
||||
The static SDL2 archive is 3120572 bytes with SHA-256
|
||||
`353065505f54e71fa8f7fff41e090dce52f39fe2aaafab85c4653648fc5f1b56`.
|
||||
It was built from commit `0baf4ac49382b537ba449901b5b6d0d189bb1fbb`
|
||||
plus the 5195-byte reviewed overlay whose SHA-256 is
|
||||
`b547260d8af40ce2360575ab7831c009036c1f35f8b525cad6fd376dc5ca9d6b`.
|
||||
|
||||
## Host integration result
|
||||
|
||||
The host harness compiled with GCC 15.2.0, `-Werror`, AddressSanitizer and
|
||||
UndefinedBehaviorSanitizer, with leak detection enabled. It completed:
|
||||
|
||||
- 600 frames;
|
||||
- video FNV-1a-64 `43f920496eb5f435`;
|
||||
- audio FNV-1a-64 `a48f47dc08c56625`;
|
||||
- digital and analog input mapping: pass;
|
||||
- Start-driven libretro shutdown callback: pass;
|
||||
- init/deinit and ASan/UBSan/leak checks: pass;
|
||||
- PS5 port structural validator: pass.
|
||||
|
||||
This is host evidence for the core and source contracts, not PS5 runtime
|
||||
evidence.
|
||||
|
||||
## ELF audit
|
||||
|
||||
Both files are ELF64 little-endian x86-64 System V PIE/DYN binaries, dynamically
|
||||
linked and not stripped. Neither has an interpreter, build ID, GNU-stack
|
||||
program header, ELF TLS segment, `.tdata` or `.tbss`. Both have 20 section
|
||||
headers; `.init_array` and `.fini_array` exist with zero size. The full section
|
||||
set is `.text`, unwind tables, dynamic symbol/hash/string/relocation tables,
|
||||
`.data.rel.ro`, `.got`, `.rodata`, empty init/fini arrays, `.dynamic`, `.data`,
|
||||
`.bss`, `.comment` and static symbol/string tables.
|
||||
|
||||
| Field | Headless | Software/RGUI |
|
||||
| --- | ---: | ---: |
|
||||
| Entry point | `0x47d10` | `0x1c29c0` |
|
||||
| Program headers | 4 | 4 |
|
||||
| First LOAD | offset `0x4000`, size `0x4e570`, RWE | offset `0x4000`, size `0x1c93e0`, RWE |
|
||||
| Other LOADs | two RW | two RW |
|
||||
| `.rela.dyn` entries | 610 | 3373 |
|
||||
| Dynamic symbols | 79 | 220 |
|
||||
| Full symbols | 1387 | 7256 |
|
||||
| Defined global symbols | 719 | 2403 |
|
||||
| Undefined symbols/imports | 73 | 210 |
|
||||
|
||||
The executable first LOAD segment is also writable because the pinned SDK
|
||||
linker script co-locates text that way. This is a material W^X weakness and a
|
||||
future execution risk; offline build success does not waive it.
|
||||
|
||||
The linker maps prove inclusion of `frontend/drivers/platform_ps5.o` and
|
||||
`cores/chimera_smokecore/chimera_smokecore.o` in both targets. The software
|
||||
map additionally proves inclusion of `SDL_ps5video.c.o`, `SDL_ps5audio.c.o`
|
||||
and `SDL_ps5joystick.c.o`, while PS5 keyboard and IME objects are absent from
|
||||
the final link.
|
||||
|
||||
## Dynamic dependencies and imports
|
||||
|
||||
Headless `DT_NEEDED`:
|
||||
|
||||
- `libkernel_web.sprx`;
|
||||
- `libSceLibcInternal.sprx`.
|
||||
|
||||
Software/RGUI additionally needs:
|
||||
|
||||
- `libSceVideoOut.sprx`;
|
||||
- `libScePad.sprx`;
|
||||
- `libSceUserService.sprx`;
|
||||
- `libSceSystemService.sprx`;
|
||||
- `libSceAudioOut.sprx`.
|
||||
|
||||
`--as-needed` removes the SDK's otherwise unconditional SceNet dependency.
|
||||
There are no undefined socket/network, `dlopen`/`dlsym`, module-loader, GNM,
|
||||
mount, reboot or console-shutdown symbols. The software target's complete Sce
|
||||
API import set is AudioOut init/open/output/close; direct-memory and equeue
|
||||
allocation/wait/release; Pad init/open/read/close plus linked-but-not-required
|
||||
lightbar/vibration calls; UserService initialization/user queries;
|
||||
`sceSystemServiceHideSplashScreen`; and VideoOut open/register/flip/event/
|
||||
close operations. Full ordered import lists are in
|
||||
`manifests/retroarch/phase-1.0a-artifacts.json`.
|
||||
|
||||
Generic RetroArch code keeps write-capable libc imports. Headless includes
|
||||
`fopen`, `ftruncate`, `fwrite`, `mkdir`, `open`, `remove`, `rename` and
|
||||
`write`; software also includes `setenv`. The fixed PS5 startup path blocks
|
||||
configuration reads, supplies no content/config/SRAM/state/core/data path and
|
||||
compiles the normal shutdown-save paths out. The claim is therefore
|
||||
control-flow-specific, not global absence of write-capable code.
|
||||
|
||||
## Entry, shutdown and static reachability
|
||||
|
||||
Source and disassembly agree on this entry sequence:
|
||||
|
||||
`_start` clears BSS, performs the inlined SDK `payload_init` sequence
|
||||
(`__crt_syscall_init`, `__kernel_init`, `__klog_init`, `__isthreaded`,
|
||||
`__patch_init`, `__rtld_init`), constructs the SDK payload runtime, calls
|
||||
`main`, which tail-jumps to `rarch_main`, then runs SDK fini/close/destroy and
|
||||
termination handling. RetroArch selects `frontend_ctx_ps5`, performs a
|
||||
contentless static-core launch, enters `runloop_iterate`, and reaches the
|
||||
linked `retro_run`. Start requests the normal RetroArch/core shutdown path;
|
||||
`retro_deinit` and the PS5 frontend deinit/shutdown callbacks are linked.
|
||||
|
||||
The SDK source and linked disassembly also prove that startup is not
|
||||
kernelwrite-free: `__patch_init` reaches credential-capability/attribute
|
||||
changes and syscall-bound writes through `kernel_copyin/out`. Those effects
|
||||
are accepted for this authorized offline link milestone under the existing
|
||||
ADR boundary, but remain unexecuted and hardware-unproven.
|
||||
|
||||
## String and policy audit
|
||||
|
||||
No personal absolute host path, credential, PS5/device address, install route,
|
||||
Payload Manager modification, elfldr modification, lifecycle probe, deploy
|
||||
client or execution helper was found. The generic RetroArch string pool keeps
|
||||
`udp://127.0.0.1:`, an RTMP template, overlay “autoload” labels and downloader
|
||||
localization even though networking, updater, dynamic cores and autoload
|
||||
routes are compiled out. The software pool also yields byte-pattern false
|
||||
positives `0.1.2.3` and `4.5.6.7`. SDK RTLD name tables contain module/dlsym
|
||||
strings, but none is an undefined application import.
|
||||
|
||||
Full local audit output for each target contains the file classification,
|
||||
ELF/readobj dump, complete symbols and undefined symbols, relocations,
|
||||
disassembly, startup/shutdown slices and strings under
|
||||
`build/phase10a/audit/{headless,software}` in `chimera-retroarch`.
|
||||
|
||||
The Chimera GFX secretscan passed across 658 text files and a clean archive of
|
||||
all 21 fork-delta files passed separately. A whole-upstream RetroArch scan
|
||||
also identified the pre-existing BearSSL sample private-key fixtures and
|
||||
mbedTLS parser/writer source literals; these are official baseline dependency
|
||||
test/source material, not additions or credentials introduced by this port.
|
||||
|
||||
No PS5 connection, request, transfer, execution, installation, autoload or
|
||||
device write occurred.
