sceSystemServiceLoadExec found its own executable through /proc/self/exe
and replaced the process with fexecve after close_range, none of which
macOS has, so on macOS every call except "exit" threw. On macOS:
- the running executable's path comes from _NSGetExecutablePath, resolved
with std::filesystem::canonical, as libSceNpEntitlementAccess and
libSceFont already do;
- the target must be an x86-64 Mach-O executable (MH_MAGIC_64,
CPU_TYPE_X86_64, MH_EXECUTE) that the user may run;
- macOS has no fexecve, so the process is replaced by path with
posix_spawn and POSIX_SPAWN_SETEXEC; POSIX_SPAWN_CLOEXEC_DEFAULT closes
every descriptor but the standard streams, as close_range does on Linux;
- before the replacement the exit starts and the shutdown callbacks run
(LibcStartExit, then LibcRunShutdown), as on Linux, so guest threads
that call a stopped library wait instead of unwinding;
- descriptor 2 gets the host standard error back before the replacement,
as on Linux, and guest_system_load_exec_standard_error runs on macOS.
A launch without arguments keeps the Linux execv path, which macOS has.
guest_system_exit finds its own executable the same way on macOS.
A read event on a listening socket took its data from FIONREAD, which a listening socket refuses on Linux, so kevent and sceKernelAddReadEvent reported 0 connections while saying one was ready. FreeBSD 11.4 gives a listening socket filt_solisten, which reports so_qlen, the completed connections waiting for accept. Ready now checks SO_ACCEPTCONN and on Linux reads a TCP listener's accept backlog from TCP_INFO, where tcp_get_info puts it in tcpi_unacked; with no host call for the count (Windows, macOS, a listener that is not TCP) it reports 1, the lower bound the readiness already implies.
Onimusha: Way of the Sword (PPSA27836 01.000.001) imports
_ZSt26__throw_bad_variant_accessv (9G6z-nF6njg) from libc, and its
bundled libc.prx does not export it, so the title fails to load with
an unresolved import.

A mounted folder uses the junction reparse tag and would otherwise be returned as a relative Volume GUID path. Only a drive path is reported, through the absolute-link text helpers.
A vertex or tessellation evaluation program whose PA_CL_VS_OUT_CNTL
enables eight guest clip distances (CLIP_DIST_ENA 0xff, both distance
vectors) failed to compile with "guest clip distances plus the all-zero
clip position distance exceed 8 clip distances", at registration and at
the draw. A program whose guest clip and cull distances together take
eight (four of each, say) compiled, but its draw failed in the pipeline
validator with "more than eight clip and cull distances in one shader".
The all-zero position distance is now added only while the guest clip and
cull distances leave one of the eight slots free. Otherwise the program
keeps its guest distances, and a primitive with a vertex at clip position
(0,0,0,0) is not removed; the EmitSetAttribute debt entry says so.
agc_position_invariance compiles one program with seven and eight clip
distances, and with three and four clip distances beside four cull
distances: the clip distance arrays are 8, 8, 4 and 4, so the all-zero
position distance is in the first and third only.

A queue that delivered an end-of-pipe interrupt from its own release stopped
delivering the flip's event for the rest of the run, so a title that raises a
release interrupt once and then waits on the flip event never saw it again.
Count the flips a queue has taken since its last delivered release interrupt:
four consecutive flips keep the latch, a fifth clears it and raises the event,
so the queue recovers within five flips. Gran Turismo 7 (PPSA01317) pairs two
flips with one release interrupt per frame, which stays under the limit, and a
title that flips without further release interrupts recovers.
Extend agc_driver_eop_interrupts: a latched queue still delivers its own
releases, flips keep reaching the video output while their event is suppressed,
an event returns once the latch clears, and a release followed by two flips
raises none.
ARCHITECTURE.md and the libSceAgcDriver debt entry now say that a
settled Windows import under 1 MiB returns to the write watch only when
no storage image overlaps it, and why.
