Title

Sifu (PPSA03001)

Content version tested

01.007.000

AnyPS5 commit

main 8dfaafe, plus the unwrap_self fix linked in a reply below (needed to unwrap the eboot and 36 of the 37 bundled modules)

System tested

Windows 11 (build 26300), MinGW GCC 15.2.0, NVIDIA GeForce RTX 5090 (NVIDIA 610.88)

Furthest point

Logos or loading screen

What is shown

Unreal Engine 4 title. First run: black for about 60 s while about 4,500 shaders are translated; with a warm shader cache the game's own LOADING screen is up by about 30 s.
The loading screen then freezes. About 120 s later Unreal's watchdog fires:

LowLevelFatalError [File:Unknown] [Line: 1214] GameThread timed out waiting for RenderThread after 120.01 secs

The crash handler then faults in libc (access violation, exit 0xC0000005); that crash is secondary. Audio and input were not tested.

Current blocker

Not a deadlock but graphics queue throughput. With APS5_PROFILE_DRAW=1, queue 0 records about 1,000 draws a second at 0.6-0.9 ms CPU each, about 2 frames a second at about 500 draws a frame. A backlog of 11-35 submissions builds up on queue 0. Async compute (queue 0x20) WAIT_REG_MEMs on labels deep in that backlog for 10-66 s, and flip submissions wait behind them, so RenderThread stalls past the 120 s watchdog.
Most of the per-draw cost is in ShaderResources::PrepareDrawBindings (about 0.5 ms per draw). I am working on that and will link the pull request here.

How it was run

Unwrapped with tools/unwrap_self.py (eboot.bin, sce_module/, prx/); the bundled modules go next to the game data as *.guest.prx.
Relinked with: relinker --windows --registry eboot.elf app.exe
app0 holds the game folder (sifu/), sce_sys/ and ue4commandline.txt. No environment variables were needed to reach the loading screen.

Linked work:

• fix(tools): place an empty segment that ends a load segment in unwrap_self #5909 fixes tools/unwrap_self.py for the eboot and 36 of the 37 bundled modules: an empty PT_TLS at the end of a PT_LOAD.
• The loading-screen freeze is draw snapshot copying in PrepareDrawBindings (about 13 MiB copied per draw, never reused on Windows). perf(agc): reuse draw snapshots across draws that nothing wrote between #5906 fixes it. With perf(agc): reuse draw snapshots across draws that nothing wrote between #5906 on main 8dfaafe the title screen ("PRESS ANY BUTTON") comes up and the watchdog no longer fires in 200 s. Numbers are in perf(agc): reuse draw snapshots across draws that nothing wrote between #5906 (comment).

Furthest point is now the title screen at about 0.5 FPS. Queue 0 still spends about 250-400 µs of CPU per draw; I'm looking at that next.
