</div>

Sets the process heap to a given Size. It can both extend and shrink the heap.

Size must be a multiple of 0x200000 (2MB).

On success, the heap base-address (which is fixed by kernel, aslr'd, and always in the Heap memory region) is written to HeapAddress.

Uses current process pool partition. The memory allocated counts towards the caller's process Memory ResourceLimit.

[2.0.0+] Size must be less than or equal to 4GB.

=== Result codes ===
'''0x0:''' Success.

'''0xCA01:''' Invalid size passed. It's either bigger than 4GB, or misaligned.

'''0xD001:''' Size is bigger than the Heap Region size.

'''0xCE01:''' KMemoryBlockAllocator slab allocator exhausted.

'''0xD401:''' The memory region is in an invalid state. Likely because a mapping was made in the heap region.

'''0x10801:''' Memory resource limit reached.

</div>

Changes permission of page-aligned memory region.

Bit2 of permission (exec) is not allowed. Setting write-only is not allowed either (bit1).

This can be used to move back and forth between ---, r-- and rw-.

=== Result codes ===
'''0x0:''' Success. The memory region was reprotected.

'''0xCC01:''' Unaligned address specified.

'''0xCA01:''' Unaligned or zero size specified.

'''0xD401:''' The provided memory region does not fall within the userland address space.

'''0xD801:''' Invalid permission specified. Valid permissions are ---, r-- and rw-.

'''0xD401:''' The provided memory region was in an invalid state. The region must have the [[#MemoryState|FlagCanReprotect]] state, and must not have the [[#MemoryAttribute|Locked]] or [[#MemoryAttribute|Uncached]] attributes.

'''0xCE01:''' Kernel resource exhausted.

</div>

Changes attribute of page-aligned memory region. The only allowed combination of Value and Mask is 0x8, which means only bit3 in [[#MemoryAttribute]] can be set or cleared.

This is used to turn on/off caching for a given memory area. Useful when talking to devices such as the GPU.

What happens "under the hood" is the "Memory Attribute Indirection Register" index is changed from 2 to 3 in the MMU descriptor.

</div>

Maps a memory range into a different range.

Mainly used for adding guard pages around stack.

Source range gets reprotected to --- (it can no longer be accessed), and bit0 is set in the source [[#MemoryAttribute]].

[1.0.0] This could be used to map into either the Alias Region or the Stack region.

[2.0.0+] This can only be used to map into the Stack region.

Code can get the range of the Alias region from [[#GetInfo]] id0=2,3, and on 2.0.0+ the range of the Stack region via [[#GetInfo]] id0=14, 15 (on 1.0.0, the Stack region had hardcoded limits).

When mapped into the Alias region, the mapped memory will have state 0x482907.

When mapped into the Stack region, the mapped memory will have state 0x5C3C0B.

Unmaps a region that was previously mapped with [[#MapMemory]].

It's possible to unmap ranges partially, you don't need to unmap the entire range "in one go".

The srcaddr/dstaddr must match what was given when the pages were originally mapped.

Puts the given event in the signaled state.

Will wake up any thread currently waiting on this event. Can potentially trigger a reschedule.

Any calls to [[#WaitSynchronization]] on this handle will return immediately, until the event's signaled state is reset.

=== Result codes ===
'''0x0:''' Success. Event is now in signaled state.

Maps the block supplied by the handle. The required permissions are different for the process that created the handle and all other processes.

Increases reference count for the KSharedMemory object. Thus in order to release the memory associated with the object, all handles to it must be closed and all mappings must be unmapped.

This one reprotects the src block with perms you give it. It also sets bit0 into [[#MemoryAttribute]].

Executable bit perm not allowed.

Closing all handles automatically causes the bit0 in [[#MemoryAttribute]] to clear, and the permission to reset.

</div>

Resets the signal on the given handle, ensuring future calls to [[#WaitSynchronization]] on this handle will sleep until the handle is signaled again. If the handle is a ReadableEvent, this returns ResultInvalidState if the event is not signaled.

If the handle is a Process, it will clear the signaled state (which is set when the process changes [[#ProcessState]]. Once the process enters the Exited state, calling ResetSignal on the process will no longer have an effect (the process is permanently signaled), and the syscall will return 0xFA01.

=== Result codes ===
'''0x0:''' Success. The signal was reset.

'''0xE401:''' The handle is invalid or of the wrong type.

'''0xFA01:''' The handle was not signaled, or the process is in exited state, causing it to be permanently signaled.

Works with HandlesNum <= 0x40.

When zero handles are passed, this will wait forever until either timeout or cancellation occurs.

Does not accept 0xFFFF8001 or 0xFFFF8000 as handles.

=== Object types ===
'''KDebug:''' signals when there is a new [[#DebugEventInfo|DebugEvent]] (retrievable via [[#GetDebugEvent]]).

'''KClientPort:''' signals when the number of sessions is less than the maximum allowed.

'''KProcess:''' signals when the process undergoes a state change (retrievable via [[#GetProcessInfo]]).

'''KReadableEvent:''' signals when the event's corresponding KWritableEvent has been signaled via [[#SignalEvent]].

'''KServerPort:''' signals when there is an incoming connection waiting to be [[#AcceptSession|accepted]].

'''KServerSession:''' signals when there is an incoming message waiting to be [[#ReplyAndReceive|received]] or the pipe is closed.

'''KThread:''' signals when the thread has exited.

=== Result codes ===
'''0x0:''' Success. One of the objects was signaled before the timeout expired, or one of the objects is a Session with a closed remote. Handle index is updated to indicate which object signaled.

'''0x7601:''' Thread termination requested. Handle index is not updated.

'''0xe401:''' Invalid handle. Returned when one of the handles passed is invalid. Handle index is not updated.

'''0xe601:''' Invalid address. Returned when the handles pointer is not a readable address. Handle index is not updated.

'''0xea01:''' Timeout. Returned when no objects have been signaled within the timeout. Handle index is not updated.

'''0xec01:''' Interrupted. Returned when another thread uses [[#CancelSynchronization]] to cancel this thread. Handle index is not updated.

'''0xee01:''' Too many handles. Returned when the number of handles passed is > 0x40.

If the referenced thread is currently in a synchronization call ([[#WaitSynchronization]], [[#ReplyAndReceive]] or [[#ReplyAndReceiveLight]]), that call will be interrupted and return 0xec01.
If that thread is not currently executing such a synchronization call, the next call to a synchronization call will return 0xec01.

This doesn't take force-pause (activity/debug pause) into account.

=== Result codes ===
'''0x0:''' Success. The thread was either interrupted or has had its flag set.

'''0xe401:''' Invalid handle. The handle given was either invalid or not a thread handle.

If the process is attached, report the Break event. Then, if [[#ContinueDebugEvent]] didn't apply IgnoreException on the thread: if TPIDR_EL0 is 0, adjust ELR_EL1 to retry to svc instruction (and set TPIDR_EL0 to 1).

Otherwise, if bit31 in reason isn't set, perform crash reporting (see Exception Handling section below), if it doesn't terminate the process adjust ELR_EL1 as well.

Otherwise just return 0.

If ReplyTargetSessionHandle is not zero, a reply from the TLS will be sent to that session.
Then it will wait until either of the passed sessions has an incoming message, is closed, a passed port has an incoming connection, or the timeout expires.
If there is an incoming message, it is copied to the TLS.

If ReplyTargetSessionHandle is zero, the TLS should contain a blank message. If this message has a C descriptor, the buffer it points to will be used as the pointer buffer. See [[IPC_Marshalling#IPC_buffers]]. Note that a pointer buffer cannot be specified if ReplyTargetSessionHandle is not zero.

After being validated, passed handles will be enumerated in order; even if a session has been closed, if one that appears earlier in the list has an incoming message, it will take priority and a result code of 0x0 will be returned.

=== Result codes ===
'''0x0:''' Success. Either a session has an incoming message or a port has an incoming connection. HandleIndex is set appropriately.

'''0xea01:''' Timeout. No handles were signalled before the timeout expired. HandleIndex is not updated.

'''0xf601:''' Port remote dead. One of the sessions has been closed. HandleIndex is set appropriately.

Maps the backing memory for a CodeMemory object into the current process.

For [[#CodeMemoryOperation|MapOwner]], memory permission must be RW-.

For [[#CodeMemoryOperation|MapSlave]], memory permission must be R-- or R-X.

Operations [[#CodeMemoryOperation|UnmapOwner/UnmapSlave]] unmap memory that was previously mapped this way.

This allows one "secure JIT" process to map the code memory as RW-, and the other "slave" process to map it R-X.

[5.0.0+] Error 0xE401 is now returned when the process owner of the Code memory object is the same as the current process.

Read/write IO registers with a hardcoded whitelist. Input address is physical-address and must be aligned to 4.

rw_mask is 0 for reading and 0xffffffff for writing. You can also write individual bits by using a mask value.

You can only write to registers inside physical pages 0x70019000 (MC), 0x7001C000 (MC0), 0x7001D000 (MC1), and they all share the same whitelist.

The whitelist is same for writing as for reading.

The whitelist is:

0x054, 0x090, 0x094, 0x098, 0x09c, 0x0a0, 0x0a4, 0x0a8, 0x0ac, 0x0b0, 0x0b4, 0x0b8, 0x0bc, 0x0c0, 0x0c4, 0x0c8, 0x0d0, 0x0d4, 0x0d8, 0x0dc, 0x0e0, 0x100, 0x108, 0x10c, 0x118, 0x11c, 0x124, 0x128, 0x12c, 0x130, 0x134, 0x138, 0x13c, 0x158, 0x15c, 0x164, 0x168, 0x16c, 0x170, 0x174, 0x178, 0x17c, 0x200, 0x204, 0x2e4, 0x2e8, 0x2ec, 0x2f4, 0x2f8, 0x310, 0x314, 0x320, 0x328, 0x344, 0x348, 0x370, 0x374, 0x37c, 0x380, 0x390, 0x394, 0x398, 0x3ac, 0x3b8, 0x3bc, 0x3c0, 0x3c4, 0x3d8, 0x3e8, 0x41c, 0x420, 0x424, 0x428, 0x42c, 0x430, 0x44c, 0x47c, 0x480, 0x484, 0x50c, 0x554, 0x558, 0x55c, 0x670, 0x674, 0x690, 0x694, 0x698, 0x69c, 0x6a0, 0x6a4, 0x6c0, 0x6c4, 0x6f0, 0x6f4, 0x960, 0x970, 0x974, 0xa20, 0xa24, 0xb88, 0xb8c, 0xbc4, 0xbc8, 0xbcc, 0xbd0, 0xbd4, 0xbd8, 0xbdc, 0xbe0, 0xbe4, 0xbe8, 0xbec, 0xc00, 0xc5c, 0xcac

[2.0.0+] Whitelist was extended with 0x4c4, 0x4c8, 0x4cc, 0x584, 0x588, 0x58c.

[2.0.0+] The IO registers in range 0x7000E400 (PMC) size 0xC00 skip the whitelist, and do a TrustZone call using [[SMC#ReadWriteRegister|ReadWriteRegister]].

[4.0.0+] Access to the Memory Controller (0x70019000) also uses smcReadWriteRegister.

Here is the whitelist imposed by that SMC, relative to the start of the PMC registers:

0x000, 0x00c, 0x010, 0x014, 0x01c, 0x020, 0x02c, 0x030, 0x034, 0x038, 0x03c, 0x040, 0x044, 0x048, 0x0dc, 0x0e0, 0x0e4, 0x160, 0x164, 0x168, 0x170, 0x1a8, 0x1b8, 0x1bc, 0x1c0, 0x1c4, 0x1c8, 0x2b4, 0x2d4, 0x440, 0x4d8

Here is the whitelist imposed by the SMC [[SMC#ReadWriteRegister|ReadWriteRegister]] (checked in addition to the whitelist in the ReadWriteRegister SVC), relative to the start of the MC registers:

Sets one of the AArch64 hardware breakpoints. The nintendo switch has 6 hardware breakpoints, and 4 hardware watchpoints. The syscall has two behaviors depending on the value of HardwareBreakPointRegisterName:

If HardwareBreakPointRegisterName < 0x10, then it sets one of the AArch64 hardware breakpoints. Flags will go to DBGBCRn_EL1, and value to DBGBVRn_EL1. The only flags the user is allowed to set are those in the bitmask 0x7F01E1. Furthermore, the kernel will or it with 0x4004, in order to set various security flags to guarantee the watchpoints only triggers for code in EL0. If the user asks for a Breakpoint Type of ContextIDR match, the kernel shall use the given DebugHandle to set DBGBVRn_EL1 to the ContextID of the debugged process.

If HardwareBreakPointRegisterName is between 0x10 and 0x20 (exclusive), then it sets one of the AArch64 hardware watchpoints. Flags will go to DBGWCRn_EL1, and the value to DBGWVRn_EL1. The only flags the user is allowed to set are those in the bitmask 0xFF0F1FF9. Furthermore, the kernel will or it with 0x104004. This will set various security flags, and set the watchpoint type to be a Linked Watchpoint. This means that you need to link it to a Linked ContextIDR breakpoint. Check the ARM documentation for more information.

Note that HardwareBreakPointRegisterName 0 to 4 match only to Virtual Address, while HardwareBreakPointRegisterName 5 and 6 match against either Virtual Address, ContextID, or VMID. As such, if you are configuring a breakpoint to link for a watchpoint, make sure you use hardware_breakpoint_id 5 or 6.

For more documentation for hardware breakpoints, check out the AArch64 documentation for the [http://infocenter.arm.com/help/index.jsp?topic=/com.arm.doc.ddi0488h/way1382455558968.html DBGBCRn_EL1 register] and the [http://infocenter.arm.com/help/topic/com.arm.doc.ddi0488h/way1382455560629.html DBGWCRn_EL1 register]

</div>

Takes in a SMC function ID in X0, and arguments for that SMC function in X1-X7.

Passing an invalid SMC function ID or calling from a core other than core 3 will result in a secure monitor panic.

The kernel parses bits 9-15 in the passed SMC function ID (per the ARM SMC calling convention), and when set uses as an indicator to translate a pointer in the associated register (X1-X7) to a physical address. The kernel will translate any address mapped as R-W, other addresses (R--, R-X, or invalid pointers) will be translated as 0/NULL.

Output is returned raw from the Secure Monitor; X0 will be the untranslated SMC result and X1-X7 will contain other SMC output (or be unchanged, depending on the SMC).

== Debugging ==
[2.0.0+] Exactly 6 debug SVCs require that [[SPL_services#GetConfig|IsDebugMode]] is non-zero. Error 0x4201 is returned otherwise.
* BreakDebugProcess
* ContinueDebugEvent
* WriteDebugProcessMemory
* SetDebugThreadContext
* TerminateDebugProcess
* SetHardwareBreakPoint

DebugActiveProcess stops execution of the target process, the normal method for resuming it requires ContinueDebugEvent(see above). Closing the debug handle also results in execution being resumed.

On [1.0.0] there's only one MemoryRegion.

On [2.0.0-4.0.0] MemoryRegion is 1 for built-ins and 0 for rest.

On [5.0.0] MemoryRegion is specified in CreateProcessArgs. There are now 4 pool partitions.

On [5.0.0] (maybe lower?) a zero ResourceLimitHandle defaults to sysmodule limits and 0x12300000 bytes of memory.

The PersonalMmHeap are allocated as follows:
* For the application, normal insecure pool is used. Carveout 5 is used to provide protection.
* For the applet, a pre-allocated secure pool segment of size 0x400000 is used.
* For sysmodules, secure pool is allocated.

= Exception handling =
First of all, a function that might be called by synchronous exception handler and that is called by the SError handler fetches the exception info, adjusts PC, panics on exceptions taken from EL1, then dispatches the exception.

The dispatcher has two mutually exclusive exception reporting methods:
* by storing information at the start of the process's TLS memregion (TPIDRRO_EL0) and jumping back to the crt0
* by using KDebug

KDebug dispatching is used when at least one of the following conditions are met:
* SMC ConfigItem KernelMemConfig bit 1 is NOT set (it isn't on retail), unless: this is a software or hardware breakpoint, or a watchpoint, or [4.0.0+?] the process is attached and this is a Google PNaCl trap instruction (see LLVM source)
* FAR doesn't point to a valid address in mapped-readable CodeStatic memory (i.e. this is the case for NRO and JIT memory) or this is one of the following exceptions (it particular, that doesn't include FP exceptions occurring in CodeStatic memory):
** Uncategorized
** IllegalState
** SupervisorCallA32
** SupervisorCallA64
** PCAlignment
** SPAlignment
** SError
** BreakpointLowerEl
** SoftwareStepLowerEl (note: no way set single-step flag; not parsed)
** WatchpointLowerEl
** SoftwareBreakpointA32 (note: not parsed)
** SoftwareBreakpointA64 (note: not parsed)

In all other cases the userland-handled exception path is taken.

KDebug path:

If the process is attached, the exception is reported to the KDebug. If the thread was continued using flag IgnoreExceptions, it returns from the exception as if nothing happened.

If the latter is not the case, or if the process isn't attached, proceed to [2.0.0+] crash reporting (or in [1.0.0] just terminate the process):
if EnableDebug is set, and depending on the process state (more than one crash per process isn't permitted) it may signal itself with ProcessState_Crashed so that PM asks NS to start creport so that creport attaches to it and reports the crashes. Otherwise, just terminate.

Userland reporting path and [[#ReturnFromException]]:

In that case, after storing the regs in the TLS, the exception handler returns to the application's crt0 (entrypoint), with X0=<error description code> (see below) and X1=SP=frame=<stack top> (see above)

|-
|}

(During normal app boot the process is invoked with X0=0 and X1=main_thread_handle. The crt0 of retail apps determines whether to boot normally or handle an exception if X0 is set to 0 or not)

The application is supposed to promptly update the contents of elr_el1 to a user handler (and any other regs it sees fit) and call [[#ReturnFromException]] (error code) to call that handler. The latter is then expected to promptly abort the program.

[[#ReturnFromException]] updates the contents of the kernel stack frame with what the user provided in the TLS structure, sets TPIDR_EL0 to 1, then:
* if the provided error code is 0, gracefully pivots and returns from exception
* if it is not, replays the exception and pass it to the KDebug (see above). One can pass 0x10001 to prevent process termination. If the process is attached, this also prevents crash-collection/termination (different from the exception handler behavior)

If an exception occurs from the above user handler, the entire exception handling process will repeat with the new exception.

Note that if a thread that wasn't faulting calls [[#ReturnFromException]], it signals an "invalid syscall" exception

Note that [[SMC|IsDebugMode]] is not used during exception-handling, except for enabling printing a message to UART-A. This UART code causes a system-hang on retail (likely due to a loop that doesn't exit). This printing doesn't seem to run when the process is attached for debugging?

</div>

Sets the process heap to a given Size. It can both extend and shrink the heap.

Size must be a multiple of 0x200000 (2MB).

On success, the heap base-address (which is fixed by kernel, aslr'd, and always in the Heap memory region) is written to HeapAddress.

Uses current process pool partition. The memory allocated counts towards the caller's process Memory ResourceLimit.

[2.0.0+] Size must be less than or equal to 4GB.

=== Result codes ===
'''0x0:''' Success.

'''0xCA01:''' Invalid size passed. It's either bigger than 4GB, or misaligned.

'''0xD001:''' Size is bigger than the Heap Region size.

'''0xCE01:''' KMemoryBlockAllocator slab allocator exhausted.

'''0xD401:''' The memory region is in an invalid state. Likely because a mapping was made in the heap region.

Changes permission of page-aligned memory region.

Bit2 of permission (exec) is not allowed. Setting write-only is not allowed either (bit1).

This can be used to move back and forth between ---, r-- and rw-.

=== Result codes ===
'''0x0:''' Success. The memory region was reprotected.

'''0xCC01:''' Unaligned address specified.

'''0xCA01:''' Unaligned or zero size specified.

'''0xD401:''' The provided memory region does not fall within the userland address space.

'''0xD801:''' Invalid permission specified. Valid permissions are ---, r-- and rw-.

'''0xD401:''' The provided memory region was in an invalid state. The region must have the [[#MemoryState|FlagCanReprotect]] state, and must not have the [[#MemoryAttribute|Locked]] or [[#MemoryAttribute|Uncached]] attributes.

</div>

Changes attribute of page-aligned memory region. The only allowed combination of Value and Mask is 0x8, which means only bit3 in [[#MemoryAttribute]] can be set or cleared.

This is used to turn on/off caching for a given memory area. Useful when talking to devices such as the GPU.

What happens "under the hood" is the "Memory Attribute Indirection Register" index is changed from 2 to 3 in the MMU descriptor.

</div>

Maps a memory range into a different range.

Mainly used for adding guard pages around stack.

Source range gets reprotected to --- (it can no longer be accessed), and bit0 is set in the source [[#MemoryAttribute]].

[1.0.0] This could be used to map into either the Alias Region or the Stack region.

[2.0.0+] This can only be used to map into the Stack region.

Code can get the range of the Alias region from [[#GetInfo]] id0=2,3, and on 2.0.0+ the range of the Stack region via [[#GetInfo]] id0=14, 15 (on 1.0.0, the Stack region had hardcoded limits).

When mapped into the Alias region, the mapped memory will have state 0x482907.

When mapped into the Stack region, the mapped memory will have state 0x5C3C0B.

This one reprotects the src block with perms you give it. It also sets bit0 into [[#MemoryAttribute]].

Executable bit perm not allowed.

Closing all handles automatically causes the bit0 in [[#MemoryAttribute]] to clear, and the permission to reset.

Resets the signal on the given handle, ensuring future calls to [[#WaitSynchronization]] on this handle will sleep until the handle is signaled again. If the handle is a ReadableEvent, this returns ResultInvalidState if the event is not signaled.

If the handle is a Process, it will clear the signaled state (which is set when the process changes [[#ProcessState]]. Once the process enters the Exited state, calling ResetSignal on the process will no longer have an effect (the process is permanently signaled), and the syscall will return 0xFA01.

=== Result codes ===
'''0x0:''' Success. The signal was reset.

'''0xE401:''' The handle is invalid or of the wrong type.

'''0xFA01:''' The handle was not signaled, or the process is in exited state, causing it to be permanently signaled.

Works with HandlesNum <= 0x40.

When zero handles are passed, this will wait forever until either timeout or cancellation occurs.

Does not accept 0xFFFF8001 or 0xFFFF8000 as handles.

=== Object types ===
'''KDebug:''' signals when there is a new [[#DebugEventInfo|DebugEvent]] (retrievable via [[#GetDebugEvent]]).

'''KClientPort:''' signals when the number of sessions is less than the maximum allowed.

'''KProcess:''' signals when the process undergoes a state change (retrievable via [[#GetProcessInfo]]).

'''KReadableEvent:''' signals when the event's corresponding KWritableEvent has been signaled via [[#SignalEvent]].

'''KServerPort:''' signals when there is an incoming connection waiting to be [[#AcceptSession|accepted]].

'''KServerSession:''' signals when there is an incoming message waiting to be [[#ReplyAndReceive|received]] or the pipe is closed.

'''KThread:''' signals when the thread has exited.

=== Result codes ===
'''0x0:''' Success. One of the objects was signaled before the timeout expired, or one of the objects is a Session with a closed remote. Handle index is updated to indicate which object signaled.

'''0x7601:''' Thread termination requested. Handle index is not updated.

'''0xe401:''' Invalid handle. Returned when one of the handles passed is invalid. Handle index is not updated.

'''0xe601:''' Invalid address. Returned when the handles pointer is not a readable address. Handle index is not updated.

'''0xea01:''' Timeout. Returned when no objects have been signaled within the timeout. Handle index is not updated.

'''0xec01:''' Interrupted. Returned when another thread uses [[#CancelSynchronization]] to cancel this thread. Handle index is not updated.

'''0xee01:''' Too many handles. Returned when the number of handles passed is > 0x40.

If the referenced thread is currently in a synchronization call ([[#WaitSynchronization]], [[#ReplyAndReceive]] or [[#ReplyAndReceiveLight]]), that call will be interrupted and return 0xec01.
If that thread is not currently executing such a synchronization call, the next call to a synchronization call will return 0xec01.

This doesn't take force-pause (activity/debug pause) into account.

=== Result codes ===

If ReplyTargetSessionHandle is not zero, a reply from the TLS will be sent to that session.
Then it will wait until either of the passed sessions has an incoming message, is closed, a passed port has an incoming connection, or the timeout expires.
If there is an incoming message, it is copied to the TLS.

If ReplyTargetSessionHandle is zero, the TLS should contain a blank message. If this message has a C descriptor, the buffer it points to will be used as the pointer buffer. See [[IPC_Marshalling#IPC_buffers]]. Note that a pointer buffer cannot be specified if ReplyTargetSessionHandle is not zero.

After being validated, passed handles will be enumerated in order; even if a session has been closed, if one that appears earlier in the list has an incoming message, it will take priority and a result code of 0x0 will be returned.

=== Result codes ===
'''0x0:''' Success. Either a session has an incoming message or a port has an incoming connection. HandleIndex is set appropriately.

'''0xea01:''' Timeout. No handles were signalled before the timeout expired. HandleIndex is not updated.

'''0xf601:''' Port remote dead. One of the sessions has been closed. HandleIndex is set appropriately.

Maps the backing memory for a CodeMemory object into the current process.

For [[#CodeMemoryOperation|MapOwner]], memory permission must be RW-.

For [[#CodeMemoryOperation|MapSlave]], memory permission must be R-- or R-X.

Operations [[#CodeMemoryOperation|UnmapOwner/UnmapSlave]] unmap memory that was previously mapped this way.

This allows one "secure JIT" process to map the code memory as RW-, and the other "slave" process to map it R-X.

[5.0.0+] Error 0xE401 is now returned when the process owner of the Code memory object is the same as the current process.

Read/write IO registers with a hardcoded whitelist. Input address is physical-address and must be aligned to 4.

rw_mask is 0 for reading and 0xffffffff for writing. You can also write individual bits by using a mask value.

You can only write to registers inside physical pages 0x70019000 (MC), 0x7001C000 (MC0), 0x7001D000 (MC1), and they all share the same whitelist.

The whitelist is same for writing as for reading.

The whitelist is:

0x054, 0x090, 0x094, 0x098, 0x09c, 0x0a0, 0x0a4, 0x0a8, 0x0ac, 0x0b0, 0x0b4, 0x0b8, 0x0bc, 0x0c0, 0x0c4, 0x0c8, 0x0d0, 0x0d4, 0x0d8, 0x0dc, 0x0e0, 0x100, 0x108, 0x10c, 0x118, 0x11c, 0x124, 0x128, 0x12c, 0x130, 0x134, 0x138, 0x13c, 0x158, 0x15c, 0x164, 0x168, 0x16c, 0x170, 0x174, 0x178, 0x17c, 0x200, 0x204, 0x2e4, 0x2e8, 0x2ec, 0x2f4, 0x2f8, 0x310, 0x314, 0x320, 0x328, 0x344, 0x348, 0x370, 0x374, 0x37c, 0x380, 0x390, 0x394, 0x398, 0x3ac, 0x3b8, 0x3bc, 0x3c0, 0x3c4, 0x3d8, 0x3e8, 0x41c, 0x420, 0x424, 0x428, 0x42c, 0x430, 0x44c, 0x47c, 0x480, 0x484, 0x50c, 0x554, 0x558, 0x55c, 0x670, 0x674, 0x690, 0x694, 0x698, 0x69c, 0x6a0, 0x6a4, 0x6c0, 0x6c4, 0x6f0, 0x6f4, 0x960, 0x970, 0x974, 0xa20, 0xa24, 0xb88, 0xb8c, 0xbc4, 0xbc8, 0xbcc, 0xbd0, 0xbd4, 0xbd8, 0xbdc, 0xbe0, 0xbe4, 0xbe8, 0xbec, 0xc00, 0xc5c, 0xcac

[2.0.0+] Whitelist was extended with 0x4c4, 0x4c8, 0x4cc, 0x584, 0x588, 0x58c.

[2.0.0+] The IO registers in range 0x7000E400 (PMC) size 0xC00 skip the whitelist, and do a TrustZone call using [[SMC#ReadWriteRegister|ReadWriteRegister]].

[4.0.0+] Access to the Memory Controller (0x70019000) also uses smcReadWriteRegister.

Here is the whitelist imposed by that SMC, relative to the start of the PMC registers:

0x000, 0x00c, 0x010, 0x014, 0x01c, 0x020, 0x02c, 0x030, 0x034, 0x038, 0x03c, 0x040, 0x044, 0x048, 0x0dc, 0x0e0, 0x0e4, 0x160, 0x164, 0x168, 0x170, 0x1a8, 0x1b8, 0x1bc, 0x1c0, 0x1c4, 0x1c8, 0x2b4, 0x2d4, 0x440, 0x4d8

Here is the whitelist imposed by the SMC [[SMC#ReadWriteRegister|ReadWriteRegister]] (checked in addition to the whitelist in the ReadWriteRegister SVC), relative to the start of the MC registers:

0x000, 0x004, 0x008, 0x00C, 0x010, 0x01C, 0x020, 0x030, 0x034, 0x050, 0x054, 0x090, 0x094, 0x098, 0x09C, 0x0A0, 0x0A4, 0x0A8, 0x0AC, 0x0B0, 0x0B4, 0x0B8, 0x0BC, 0x0C0, 0x0C4, 0x0C8, 0x0D0, 0x0D4, 0x0D8, 0x0DC, 0x0E0, 0x100, 0x108, 0x10C, 0x118, 0x11C, 0x124, 0x128, 0x12C, 0x130, 0x134, 0x138, 0x13C, 0x158, 0x15C, 0x164, 0x168, 0x16C, 0x170, 0x174, 0x178, 0x17C, 0x200, 0x204, 0x238, 0x240, 0x244, 0x250, 0x254, 0x258, 0x264, 0x268, 0x26C, 0x270, 0x274, 0x280, 0x284, 0x288, 0x28C, 0x294, 0x2E4, 0x2E8, 0x2EC, 0x2F4, 0x2F8, 0x310, 0x314, 0x320, 0x328, 0x344, 0x348, 0x370, 0x374, 0x37C, 0x380, 0x390, 0x394, 0x398, 0x3AC, 0x3B8, 0x3BC, 0x3C0, 0x3C4, 0x3D8, 0x3E8, 0x41C, 0x420, 0x424, 0x428, 0x42C, 0x430, 0x44C, 0x47C, 0x480, 0x484, 0x4C4, 0x4C8, 0x4CC, 0x50C, 0x554, 0x558, 0x55C, 0x584, 0x588, 0x58C, 0x670, 0x674, 0x690, 0x694, 0x698, 0x69C, 0x6A0, 0x6A4, 0x6C0, 0x6C4, 0x6F0, 0x6F4, 0x960, 0x970, 0x974, 0x9B8, 0xA20, 0xA24, 0xA88, 0xA94, 0xA98, 0xA9C, 0xAA0, 0xAA4, 0xAA8, 0xAAC, 0xAB0, 0xAB4, 0xAB8, 0xABC, 0xAC0, 0xAC4, 0xAC8, 0xACC, 0xAD0, 0xAD4, 0xAD8, 0xADC, 0xAE0, 0xB88, 0xB8C, 0xBC4, 0xBC8, 0xBCC, 0xBD0, 0xBD4, 0xBD8, 0xBDC, 0xBE0, 0xBE4, 0xBE8, 0xBEC, 0xC00, 0xC5C, 0xCAC

If HardwareBreakPointRegisterName < 0x10, then it sets one of the AArch64 hardware breakpoints. Flags will go to DBGBCRn_EL1, and value to DBGBVRn_EL1. The only flags the user is allowed to set are those in the bitmask 0x7F01E1. Furthermore, the kernel will or it with 0x4004, in order to set various security flags to guarantee the watchpoints only triggers for code in EL0. If the user asks for a Breakpoint Type of ContextIDR match, the kernel shall use the given DebugHandle to set DBGBVRn_EL1 to the ContextID of the debugged process.

If HardwareBreakPointRegisterName is between 0x10 and 0x20 (exclusive), then it sets one of the AArch64 hardware watchpoints. Flags will go to DBGWCRn_EL1, and the value to DBGWVRn_EL1. The only flags the user is allowed to set are those in the bitmask 0xFF0F1FF9. Furthermore, the kernel will or it with 0x104004. This will set various security flags, and set the watchpoint type to be a Linked Watchpoint. This means that you need to link it to a Linked ContextIDR breakpoint. Check the ARM documentation for more information.

Note that HardwareBreakPointRegisterName 0 to 4 match only to Virtual Address, while HardwareBreakPointRegisterName 5 and 6 match against either Virtual Address, ContextID, or VMID. As such, if you are configuring a breakpoint to link for a watchpoint, make sure you use hardware_breakpoint_id 5 or 6.

For more documentation for hardware breakpoints, check out the AArch64 documentation for the [http://infocenter.arm.com/help/index.jsp?topic=/com.arm.doc.ddi0488h/way1382455558968.html DBGBCRn_EL1 register] and the [http://infocenter.arm.com/help/topic/com.arm.doc.ddi0488h/way1382455560629.html DBGWCRn_EL1 register]

</div>

Takes in a SMC function ID in X0, and arguments for that SMC function in X1-X7.

Passing an invalid SMC function ID or calling from a core other than core 3 will result in a secure monitor panic.

The kernel parses bits 9-15 in the passed SMC function ID (per the ARM SMC calling convention), and when set uses as an indicator to translate a pointer in the associated register (X1-X7) to a physical address. The kernel will translate any address mapped as R-W, other addresses (R--, R-X, or invalid pointers) will be translated as 0/NULL.

Output is returned raw from the Secure Monitor; X0 will be the untranslated SMC result and X1-X7 will contain other SMC output (or be unchanged, depending on the SMC).

== Debugging ==
[2.0.0+] Exactly 6 debug SVCs require that [[SPL_services#GetConfig|IsDebugMode]] is non-zero. Error 0x4201 is returned otherwise.
* BreakDebugProcess
* ContinueDebugEvent
* WriteDebugProcessMemory
* SetDebugThreadContext
* TerminateDebugProcess
* SetHardwareBreakPoint

DebugActiveProcess stops execution of the target process, the normal method for resuming it requires ContinueDebugEvent(see above). Closing the debug handle also results in execution being resumed.

On [5.0.0] MemoryRegion is specified in CreateProcessArgs. There are now 4 pool partitions.

On [5.0.0] (maybe lower?) a zero ResourceLimitHandle defaults to sysmodule limits and 0x12300000 bytes of memory.

The PersonalMmHeap are allocated as follows:
* For the application, normal insecure pool is used. Carveout 5 is used to provide protection.
* For the applet, a pre-allocated secure pool segment of size 0x400000 is used.
* For sysmodules, secure pool is allocated.

= Exception handling =
First of all, a function that might be called by synchronous exception handler and that is called by the SError handler fetches the exception info, adjusts PC, panics on exceptions taken from EL1, then dispatches the exception.

The dispatcher has two mutually exclusive exception reporting methods:
* by storing information at the start of the process's TLS memregion (TPIDRRO_EL0) and jumping back to the crt0
* by using KDebug

KDebug dispatching is used when at least one of the following conditions are met:
* SMC ConfigItem KernelMemConfig bit 1 is NOT set (it isn't on retail), unless: this is a software or hardware breakpoint, or a watchpoint, or [4.0.0+?] the process is attached and this is a Google PNaCl trap instruction (see LLVM source)
* FAR doesn't point to a valid address in mapped-readable CodeStatic memory (i.e. this is the case for NRO and JIT memory) or this is one of the following exceptions (it particular, that doesn't include FP exceptions occurring in CodeStatic memory):
** Uncategorized
** IllegalState
** SupervisorCallA32
** SupervisorCallA64
** PCAlignment
** SPAlignment
** SError
** BreakpointLowerEl
** SoftwareStepLowerEl (note: no way set single-step flag; not parsed)
** WatchpointLowerEl
** SoftwareBreakpointA32 (note: not parsed)
** SoftwareBreakpointA64 (note: not parsed)

In all other cases the userland-handled exception path is taken.

KDebug path:

If the process is attached, the exception is reported to the KDebug. If the thread was continued using flag IgnoreExceptions, it returns from the exception as if nothing happened.

If the latter is not the case, or if the process isn't attached, proceed to [2.0.0+] crash reporting (or in [1.0.0] just terminate the process):
if EnableDebug is set, and depending on the process state (more than one crash per process isn't permitted) it may signal itself with ProcessState_Crashed so that PM asks NS to start creport so that creport attaches to it and reports the crashes. Otherwise, just terminate.

Userland reporting path and [[#ReturnFromException]]:

In that case, after storing the regs in the TLS, the exception handler returns to the application's crt0 (entrypoint), with X0=<error description code> (see below) and X1=SP=frame=<stack top> (see above)

|-
|}

(During normal app boot the process is invoked with X0=0 and X1=main_thread_handle. The crt0 of retail apps determines whether to boot normally or handle an exception if X0 is set to 0 or not)

The application is supposed to promptly update the contents of elr_el1 to a user handler (and any other regs it sees fit) and call [[#ReturnFromException]] (error code) to call that handler. The latter is then expected to promptly abort the program.

[[#ReturnFromException]] updates the contents of the kernel stack frame with what the user provided in the TLS structure, sets TPIDR_EL0 to 1, then:
* if the provided error code is 0, gracefully pivots and returns from exception
* if it is not, replays the exception and pass it to the KDebug (see above). One can pass 0x10001 to prevent process termination. If the process is attached, this also prevents crash-collection/termination (different from the exception handler behavior)

If an exception occurs from the above user handler, the entire exception handling process will repeat with the new exception.

Note that if a thread that wasn't faulting calls [[#ReturnFromException]], it signals an "invalid syscall" exception

Note that [[SMC|IsDebugMode]] is not used during exception-handling, except for enabling printing a message to UART-A. This UART code causes a system-hang on retail (likely due to a loop that doesn't exit). This printing doesn't seem to run when the process is attached for debugging?

Package2

2025-12-19T05:44:32Z

Ootulp:

Present in the firmware package titles (0100000000000819, 010000000000081A, 010000000000081B and 010000000000081C) and installed into eMMC storage's [[Flash_Filesystem#User_Partitions|BCPKG2 partitions]], "package2" contains the Switch kernel and the built-in system modules.

= Format =
Package2 is distributed in an already encrypted format. Therefore, it's not additionally encrypted when installed into the flash filesystem.

== Encryption ==
Package2's contents are AES-CTR encrypted with a key known only by TrustZone.

The encrypted header's CTR is stored as it's first 0x10 bytes (offset 0x100).
The encrypted body is divided in up to 4 sections, each one with a CTR stored inside the decrypted header.

== Header ==
When decrypted, package2's header is as follows.

|}

Each section follows each other immediately and is encrypted with the same key used for encrypting the header.
The section offsets are relative to a base, which is typically 0x80000000 pointing to the base of DRAM.

Before being decrypted, the encrypted header's CTR additionally encodes metadata used to validate package2's contents as follows:
* Size of the entire package2 with the raw header = ctr_word2 ^ ctr_word3 ^ ctr_word0
* Key generation = ((ctr_word1 ^ (ctr_word1 >> 16)) & 0xFF) ^ (ctr_word1 >> 24)

In [4.0.0], the key generation must be less or equal to 4.

== Section 0 ==
When decrypted, this section contains the plaintext Switch kernel binary.

== Section 1 ==
When decrypted, this section contains the built-in system modules encapsulated in a custom format.

Note: On firmware [[8.0.0]] INI1 is contained within the Kernel and section 1 is empty with NULL SHA256 to match.

===== Compression =====
The compression used here is BLZ, with a modified footer since 3ds. The footer is now 0xC bytes instead of 0x8, and has the form u32 compressed_data_len; u32 footer_size; u32 additional_len_when_uncompressed;

== Section 2 ==
This section has a valid CTR and SHA-256 hash (over NULL) stored in the package2's header, but it's size is always 0. Likely reserved for future expansion.

== Section 3 ==
This section is not present (CTR and SHA-256 hash in package2's header are NULL). Likely reserved for future expansion.
