The four guest_arena tests still pass with the mach_vm_region walk
disabled, because TryReserve marks every 1 GiB chunk it cannot reserve
as occupied. guest_arena_gap reads the host map before the arena
reserves its range and requires a fixed guest mapping in free space
that shares a chunk with a host region to be accepted.
The debt entry also records that on macOS 27.0.1 (M4 Pro) the
unmappable range starts at 0xF_C000_0000.
#7527's selected-record limit test reads a record's descriptor words through the
table snapshot's shared words list; this branch keeps a snapshot's words per column,
so the test reads them from its column instead.
AudioOut2 turns controller haptic PCM into motor rumble only when no
controller sound card plays it, which is the case for a DualSense over
Bluetooth. PadInput then dropped that rumble for every DualSense, so
titles that vibrate through haptic audio never rumbled one over
Bluetooth. A DualSense now takes it like any other controller; with a
sound card no haptic rumble is submitted, so nothing plays twice.

A per-game relinker-patches.toml (or --patches) replaces verified bytes in
the input executable and bundled modules before conversion. Entries are
checked against the expected bytes and against every in-place writer,
the ELF header range and relocation targets. An <output-stem>.patches.toml
manifest records the applied entries, and --verify-patches checks an input
or a converted output. With no patch file the output is unchanged.
sceSslConnect verifies the server's chain under MBEDTLS_SSL_VERIFY_OPTIONAL and returns the first failure the connection's verify options select, with the SSL_ERROR_* codes KytyPS5 lists. The initial options are all five checks, so a connection whose title never sets them fails closed: with no CA loaded it returns SSL_ERROR_UNKNOWN_CA instead of throwing. The result is final for the connection: a failure sends close_notify, later sceSslConnect calls return the same code, and sceSslRead and sceSslWrite throw. A verify callback runs once after the handshake, outside the session lock, with the connection id, that code, handles to a copy of the peer chain that the context's certificate readers accept, the chain length and the user argument; a negative return fails the connect with SSL_ERROR_APPLICATION_VERIFICATION_CALLBACK_CHECK. The ALPN list set with sceSslSetAlpn is split on commas and offered, sceSslGetAlpnSelected returns the protocol the server chose, and the minimum version floors the handshake at TLS 1.2. A socket that would block returns SSL_ERROR_WANT_POLLIN or WANT_POLLOUT from connect, read and write and the next sceSslConnect resumes the handshake; the BIO maps a reset to MBEDTLS_ERR_NET_CONN_RESET, which returns SSL_ERROR_SOCKET_CLOSED, and tells a blocking socket's expired receive timeout, which returns SSL_ERROR_READ_TIMEOUT, apart from a non-blocking would-block. sceSslClose sends close_notify once and marks the connection closed. The debt entry records the default options and the situation-to-code choices as unverified and drops the title IDs.
Repacked copies and depth stencil copies allocated device-local memory
directly and stopped the title on a refusal; they now take the same
allocation path as the other images. Device buffers choose their host
fallback type the same way, the host placement line carries the cumulative
MiB, and the debt file records that a placed image stays in host memory
for its lifetime.
Resolve the docs/dev/debt/relinker.md conflict with #5994: keep its
sce_module syscall-scan entry, which now also stops at the end of the
last unwind function when the PLT comes before the code (it calls the
same FindSceCodeEnd), and its /libexec/ld-elf.so.1 start in the code
analysis entry, with this PR's end for a PLT before the code.

Converted guest modules never ran their DT_PREINIT_ARRAY entries: the
reader validated the array and the unused-NID filter kept its targets,
but no writer emitted or ran it. ld.so runs a shared object's preinit
array only for the main executable, so the Linux output runs the
entries from the DT_INIT stub before the module initializer; the macOS
and Windows outputs run them before the initializer in their startup
stubs, and the deferred Windows output exports a thunk that runs them
before the initializer for runtime-loaded modules. A module with a
preinit array and no initializer is still rejected, since the Linux
stub exists only with one.
libSceCesCs goes to 17 of 17: three-byte EUC-JP JIS X 0212 (0x8F)
characters convert through a table read from the Unicode consortium's
JIS0212.TXT, both directions, so sceCesEucJpToUcs2, the MbcsStrTo*
and *Get*Len forms and the context conversions accept them, and a
character with cells in both JIS X 0208 and JIS X 0212 still encodes
to the two-byte form. sceCesRefersUcsProfileCp1250 returns a profile
with the Windows-1250 table of Microsoft's bestfit1250.txt, accepted
by the SBC and context conversions.
The AudioOut HDMI bitstream Sys family follows the Ex ports: SysOpen
opens a port only for mode 5, the TrueHD MAT route EVO-PLAYER-PS5
reads from the firmware 12.70 mode tables, paced at 192 kHz with no
host device; SysConfigureOutput accepts the observed HDMI MAT switch;
SysClose closes a Sys port. sceAudioOut2MasteringGetState fills the
states by states id with the descriptors KytyPS5 declares, SetParam
answers a null parameter with the mastering invalid-API-parameter
error, Set3DLatency follows KytyPS5's output validation (0x80268001
above 2, any user), SetSystemDebugState records the debug state id,
and GetSpeakerArrayCoefficients returns the front pair KytyPS5 and
prosper both return.
sceAudioInOpen accepts param 0x10 as float mono like KytyPS5; HqOpen
answers a longer grain or a lower rate with the invalid-size and
invalid-frequency errors; AsyncOpen also accepts the 384-sample grain
SharpProspero documents. sceGameUpdateGetAddcontLatestVersion answers
a null entitlement label with 0x80412803, as prosper does.
libkernel exported scePthreadAttrSetschedpolicy and
scePthreadAttrSetinheritsched but not the matching getters,
scePthreadAttrGetschedpolicy (NID NMyIQ9WgWbU) and
scePthreadAttrGetinheritsched (NID lpMP8HhkBbg), so a title that
imports either one stopped at startup on the unresolved import. Dragon
Ball Xenoverse 2 (PPSA08587) imports both.
Implement them as FreeBSD 11.4 libthr implements
pthread_attr_getschedpolicy and pthread_attr_getinheritsched
(lib/libthr/thread/thr_attr.c): a null or uninitialized attribute
returns EINVAL (0x80020016), as does a null output of
scePthreadAttrGetschedpolicy; otherwise the attribute's policy or
inheritance is stored and 0 is returned. libthr writes through a null
output of the inheritance getter unchecked, so that case throws, as
pthread_attr_getinheritsched and scePthreadAttrGetsolosched do.
Neither getter was measured on a console. The scePthreadAttr entry in
docs/dev/debt/libkernel.md, which describes the calls measured on a
PS5, now says so and records the throw.

sceNetCtlRegisterCallback and sceNetCtlRegisterCallbackV6 stored only
the function and dropped its argument, and sceNetCtlCheckCallback
returned 0 without calling anything, so a title that polls
sceNetCtlCheckCallback until its callback reports IPOBTAINED never
got the event.
Each callback slot now keeps the function, its argument and the last
event it received; unregistration clears the slot. With no IPv4
callback registered, sceNetCtlCheckCallback returns 0 without querying
the host. Otherwise it takes the state from the same host-interface
predicate as sceNetCtlGetState, IPOBTAINED (3) or DISCONNECTED (1)
(shadPS4 src/core/libraries/network/net_ctl_codes.h L27-29
@15abf68c9b52), marks the IPv4 slots whose last event differs and
calls them on the calling thread with their argument after the lock is
released, so a callback can unregister itself. Delivery once per state
change and slot follows KytyPS5 src/libs/network.cpp @9e41d8320a27
(NetCtlCallbackSlot L3447-3451, NetCtlCheckCallback L3648-3661,
NetCtlRegisterCallback L3687-3707); shadPS4 net_ctl_obj.cpp L47-57
delivers on every check instead, and the debt entry records the
difference and that KytyPS5 calls the callbacks under its lock.
sceNetCtlTerm clears both tables, as KytyPS5 NetCtlTerm (L3625-3633)
does. V6 slots keep their argument but get no event, since no source
says which call delivers them.
NetCtlCallback is now an APS5_VABI pointer, so the Windows build calls
the guest function with the System V ABI.

Rosetta sets RDTSCP's ECX to its constant TSC_AUX, 0xAAAAAAAB, which is
not a processor index. --to-rosetta already makes RDPID return processor
0 for the same reason, so code reading the processor through RDTSCP saw
a different value from code reading it through RDPID.
--to-rosetta now moves RDTSCP into an optional stub that runs the
instruction unchanged and then loads 0 into ECX with a MOV, which
leaves the counter in EDX:EAX and the flags as they were. A site with no
movable instruction after it for the jump is kept, as for RDPID. The
Intel target and a plain relink are unchanged.
