Cemu never showed a frame on DroidDeck: its Getting Started dialog blocked
every first launch (the folder picker cannot reach ROMs), the session's
controller helper aborted it, and the desktop's Vulkan renderer drew no
cursor. With the Turnip KGSL fix in the driver and the haptic-optional
Cemu in the catalog, this makes the app side complete:
- bannerlator-pad-defaults seeds Cemu's settings.xml once: the Wii U games
folder, Vulkan, and Cubeb audio on the default device for both the TV
and the GamePad speaker at full volume (Wipeout 3 plays through the
GamePad; Cemu's own default is 20 %).
- The Cemu tile launches full screen (-f).
- libfakeinput.so is preloaded into every session process and exported its
static C++ runtime (~7000 symbols); programs unwound through it and
aborted (shadPS4 in pthread_exit, Cemu's controller thread). Link with
--exclude-libs,ALL, and fail the build if the runtime leaks out again.
- On the Vulkan and GLES desktops the pointer worked but no cursor was
drawn: wlroots hands the cursor to the app's compositor, which draws
none. WLR_NO_HARDWARE_CURSORS=1 makes labwc composite it itself.
Device-tested on the FIT: Super Mario 3D World in-game at 35-37 fps with
sound, Deus Ex HR DC and Wipeout 3 launch with sound; RPCS3, Dolphin and a
Steam session (FlatOut) unchanged on the same driver.
Brings the proot patch set up to WinNative 53836ca9 on top of the #772 port:
- trace prctl, setrlimit and prlimit64 in the seccomp filter only for the
arguments proot acts on, and uname only where the core rewrites it
- answer a seccomp stop's filter flags from the registers fetched for its
translation, reuse those registers, and skip the sysexit stop of wait4 left
to the kernel and accept without a sockaddr; the flags come from proot's list
merged with the enabled extensions, and a syscall an extension replaced
keeps its exit stop
- take a clone3 child's flags and exit signal from struct clone_args
- name a thread's /proc/self by its thread group and resolve /proc/thread-self
- translate fchmodat2, send openat2 callers to openat, and bound sysnum lookups
by the table length
- sweep relatives only for tracees that have children or ptracees, and empty
the per-stop memory collector instead of reallocating it
