A title is jailed (agreed on #11216). FreeBSD 11.4 prison_priv_check denies
PRIV_SCHED_RTPRIO, PRIV_SCHED_SET and PRIV_SCHED_SETPRIORITY to a jailed caller.

sceKernelHasTrinityMode returns 0, the answer of a base PS5, as
sceKernelIsTrinityMode already does. Two public readings of firmware
libkernel (OpenAGC for 11.60, Backport for 11.00 to 12.70) say it
compares hw.sce_main_socid with its low five bits cleared against
0x840fc0; the base PS5 SoC id recorded for sceKernelGetMainSocId,
0x840f80, fails that test. The prototype int (void) comes from the 23
calls in a UE5 title, each storing setne of the result in a guarded
static with no argument set up.
Titles import it from libkernel, but only the libkernel_sys placeholder
inventory exported it, as a throwing stub. The export moves to libkernel
next to sceKernelIsTrinityMode, and the inventory and its counts drop
the entry. guest_operation_mode checks the result.
sceKernelCallIndirectBuffer, sceKernelCallIndirectBuffer2,
sceKernelCallIndirectBuffer3, sceKernelGiveDirectMemoryToMapper and
sceKernelMapperGetParam follow firmware 13.42's libkernel_sys: the
submit calls queue the buffer on the AMM queue, the direct memory call
keeps the library's 2 MiB checks and the parameter call copies the
size and the AMM address ranges. The kernel-side checks that are not
known throw.

sceKernelWriteMapCommand2, sceKernelWriteUnmapToPrtCommand,
sceKernelWriteWriteAddressCommand, sceKernelWriteWriteCounterCommand,
sceKernelWriteWaitOnAddressCommand, sceKernelWriteWaitOnCounterCommand
and sceKernelWriteEventQueueOnCompletionCommand follow the checks of
firmware 13.42's libkernel and record this project's command layout.
Without the PRT flag, sceKernelWriteMapCommand2 is
sceKernelWriteMapCommand, as on the console. The debt files record where
the existing writers' checks differ from the firmware.

Without AT_SYMLINK_FOLLOW, linkat of a symbolic link threw on Windows.
CreateHardLinkW links the link's own reparse point rather than its target,
dangling or not, so it gives FreeBSD's behaviour. NTFS cannot hard-link a
directory, so a symbolic link or junction to a directory still throws there.
guest_kernel_sys now runs the symbolic link linkat checks on Windows too.

pthread_condattr_getclock reached NotImplemented_nid_no_patch for a null
output pointer with a valid attribute. Measured as a payload process on
a device, that call faults, as does scePthreadCondattrGetclock in the
same case, so both now throw std::invalid_argument. Every other measured
result of the condition attribute clock getters and setters already
matched. The test covers every invalid clock ID from -1 to 16.
Return the main program's handle, the first one sceKernelGetModuleList
lists and one sceKernelGetModuleInfo accepts. reSOT (PPSA99023) imports
it from libkernel and passes the handle to sceKernelGetModuleInfo to find
its own code segment; before this its eboot failed to load on the
unresolved import.
The PS5 3.20 export lists have it in libkernel as well as libkernel_sys,
and on Windows a libkernel import never reaches libkernel_sys, so the
throwing libkernel_sys stub moves to libkernel as pselect did.

Both call libkernel's pthread_mutex_init and pthread_mutexattr_init and
return 0x80020000 | errno on error, as shadPS4 (ce74386) exports them as
ORBIS(posix_pthread_mutex_init) and ORBIS(posix_pthread_mutexattr_init)
and ChonkyStation4 (c101a23) maps them to its POSIX init functions. A
mutex made without attributes is error-checking. FreeBSD 11.4's
malloc-internal _pthread_mutex_init_calloc_cb makes a normal mutex
instead; the gap is recorded in the libkernel_sys debt file.

kldstat was a NotImplemented stub. It now follows FreeBSD 11.4's
sys_kldstat (sys/kern/kern_linker.c): only the version field is read
(EFAULT when that fails), and a version other than 1056
(struct kld_file_stat_1) or 2080 (struct kld_file_stat) is EINVAL.
No linker file is listed here, as for kldnext, so every file id then
gets ENOENT and the structure is never written.

rtprio_thread read and wrote the guest rtprio struct in place, and
sched_rr_get_interval wrote the interval in place, so a non-null pointer
into unmapped or read-only memory crashed the host. rtprio_thread now
copies the struct in with GuestCopyIn_nid_no_patch before the thread
lookup for RTP_SET, as FreeBSD's sys_rtprio_thread does, and builds the
RTP_LOOKUP result locally and copies it out with
GuestCopyOut_nid_no_patch. sched_rr_get_interval copies its interval out
the same way. A failed copy returns EFAULT.
