= Protocol =
Switch game cartridges use a simple (but Nintendo proprietery) SPI-like bus with 8-bit width (DAT7..0). It is very similar to the bus interface of 3DS game cartridges, except with very different commands.

The Switch host starts a transfer by first pulling CS low, followed by clocking a byte each clock cycle. The bus data will always be ready before the rising edge of the CLK signal, so that it can be captured on the rising edge.
After command bytes are written to the bus, the direction of the bus implicitly changes and the game cartridge responds. The Switch host keeps clocking while the game cartridge responds.
After the transfer is ended, the CS line is pulled high again.

Commands are 16 bytes long, and followed immediately by a 4-byte CRC-32 over the command bytes. After this, the Switch stops driving the data bus, and the bus will be 'floating'. Due to the pull-ups on the bus, it will slowly converge to logic HIGH state. The Switch will clock 2 cycles to allow the bus to settle a direction change. The Switch host will then clock another cycle and if the game cartridge didn't receive the CRC OK, it will respond with "01". Otherwise it will respond with "00" and pull DAT0 low on the next cycle to signal it is busy. The Switch host will then keep clocking until the cartridge is ready.

When the game cartridge is ready to send the actual data response, it will pull the DAT0 pin high for 2 cycles to let the Switch host know. After this, the game cartridge will send the actual data response bytes.

The actual response bytes are also followed immediately by a 4-byte CRC-32 over the actual data response bytes.

A typical boot up sequence of a game cartridge (in this case, the game "1,2 Switch") looks like this:

Testpads

2019-12-15T05:28:52Z

Shuffle2: Fix the UART-A pads. No idea why these were inverted.

The Nintendo Switch mainboard has a series of testpads on the front and back, presumably used in factory test, diagnostics, and early board bringup procedures.

== Raw Logic captures ==

These are reference materials, taken from poking at I/O on various testpads. https://github.com/hedgeberg/Switch-Logic-Captures

TSEC

2019-01-11T01:04:21Z

Shuffle2: /* Operations */

TSEC (Tegra Security Co-processor) is a dedicated unit powered by a NVIDIA Falcon microprocessor with crypto extensions.

= Driver =
A host driver for communicating with the TSEC is mapped to physical address 0x54500000 with a total size of 0x40000 bytes and exposes several registers.

== Registers ==
Registers from 0x54500000 to 0x54501000 are used to configure the host interface (HOST1X).

Registers from 0x54501000 to 0x54502000 are a MMIO window for communicating with the Falcon microprocessor. From this range, the subset of registers from 0x54501400 to 0x54501FE8 are specific to the TSEC and are subdivided into:
* 0x54501400 to 0x54501500: SCP (Secure Crypto Processor?).
* 0x54501500 to 0x54501600: TRNG (True Random Number Generator).
* 0x54501600 to 0x54501700: TFBIF (Tegra Framebuffer Interface).
* 0x54501700 to 0x54501800: DMA.
* 0x54501800 to 0x54501900: TEGRA (miscellaneous interfaces).

== SCP ==
Part of the information here (which hasn't made it into envytools documentation yet) was shared by [https://wiki.0x04.net/wiki/Marcin_Ko%C5%9Bcielnicki mwk] from reverse engineering falcon processors over the years.

=== Authenticated Mode ===
==== Entry ====
From non-secure mode, upon jumping to a page marked as secret, a secret fault occurs. This causes the CPU to verify the region specified in $cauth against the MAC loaded in $c6. If the comparison is successful, the valid bit (bit0) is set on all pages in the $cauth region, and $pc is set to the base of the $cauth region. If the comparsion fails, the CPU is halted.

==== Exit ====
The CPU automatically goes back to non-secure mode when returning back into non-secret pages. When this happens, the valid bit (bit0) in the TLB flags is cleared for all secret pages.

==== Implementation ====
Under certain circumstances, it is possible to observe [[#csigauth|csigauth]] being briefly written to [[#TSEC_SCP_INSN_STAT|TSEC_SCP_INSN_STAT]] as "csigauth $c4 $c6" while the opcodes in [[#TSEC_SCP_AES_STAT|TSEC_SCP_AES_STAT]] are set to "cxsin" and "csigauth", respectively.

Via [[#TSEC_SCP_SEQ0_STAT|TSEC_SCP_SEQ0_STAT]] it can be observed that a 3-sized macro sequence is loaded into cs0 during a secure mode transition.

|}

==== csigauth ====
<code>00000000: f5 3c XY d8 csigauth $cY $cX</code>

Takes 2 crypto registers as operands and is automatically executed when jumping to a code region previously uploaded as secret. This instruction does not work in secure mode.

==== csigclr ====
<code>00000000: f5 3c 00 e0 csigclr</code>

This instruction takes no operands and appears to clear the saved cauth signature used by the csigenc instruction.

==== cchmod ====
<code>00000000: f5 3c XY a8 cchmod $cY 0X</code> or <code>00000000: f5 3c XY a9 cchmod $cY 1X</code>

This instruction takes a crypto register and a 5 bit immediate value which represents the [[#ACL|ACL]] mask to set.

==== crnd ====
<code>00000000: f5 3c 0X 90 crnd $cX</code>

This instruction initializes a crypto register with random data.

Executing this instruction only succeeds if the TRNG is enabled for the SCP, which requires taking the following steps:
* Write 0x7FFF to TSEC_TRNG_CLKDIV.
* Write 0x3FF0000 to TSEC_TRNG_UNK0.
* Write 0xFF00 to TSEC_TRNG_UNK2.
* Write 0x1000 to [[#TSEC_SCP_CTL1|TSEC_SCP_CTL1]].

Otherwise it hangs forever.

=== ACL ===
{| class="wikitable" border="1"
! Bit
! Meaning
|-
| 0 || Secure key. Forced set if bit1 is set. Once cleared, cannot be set again.
|-
| 1 || Secure readable. Once cleared, cannot be set again.
|-
| 2 || Insecure key. Forced set if bit3 is set. Forced clear if bit0 is clear. Can be toggled back and forth.
|-
| 3 || Insecure readable. Forced clear if bit1 is clear. Can be toggled back and forth.
|-
| 4 || Insecure overwritable. Can be toggled back and forth.
|}

==== Initial values ====
On SCP boot, the ACL is 0x1F for all $cX.

Loading into $cX using xdst instruction sets ACL($cX) to 0x13 and 0x1F, for secure and insecure mode respectively.

Spilling a $cX to DMEM using xdld instruction is allowed if (ACL($cX) & 2) or (ACL($cX) & 8), for secure and insecure mode respectively.

Loading a secret into $cX sets a per-secret ACL, unconditionally.

=== cauth ===
$cauth is a special purpose register in the CPU.

{| class="wikitable" border="1"
! Bits

| 0-7 || Start of region to authenticate (in 0x100 pages)

| 18 || Unknown
|-
| 19 || Unknown
|-
| 20-23 || Unknown
|-
| 24-31 || Size of region to authenticate (in 0x100 pages)
|}

=== cxset ===
cxset instruction provides a way to change behavior of a variable amount of successively executed DMA-related instructions.

for example: <code>000000de: f4 3c 02 cxset 0x2</code>

can be read as: <code>dma_override(type=crypto_reg, count=2)</code>

The argument to cxset specifies the type of behavior change in the top 3 bits, and the number of DMA-related instructions the effect lasts for in the lower 5 bits.

{| class=wikitable
! Bits || Description
|-
| 0-4 || Number of instructions it is valid for (0x1f is a special value meaning infinitely many instructions -- until overriden by another cxset)
|-
| 5 || Crypto destination/source select (0=crypto register, 1=crypto stream)
|-
| 6 || External memory override (0=Disabled, 1=Enabled)
|-
| 7 || Internal memory select (0=DMEM, 1=IMEM)
|}

==== DMA-Related Instructions ====
At least the following instructions may have changed behavior, and count against the cxset "count" argument: <code>xdwait</code>, <code>xdst</code>, <code>xdld</code>.

For example, if override type=0b000, then the "length" argument to <code>xdst</code> is instead treated as the index of the target $cX register.

=== Secrets ===
Falcon's Authenticated Mode has access to 64 128-bit keys which are burned at factory. These keys can be loaded by using the $csecret instruction which takes the target crypto register and the key index as arguments.

Joy-Con

2018-08-30T02:30:59Z

Shuffle2: Reverted edits by AveSatanas (talk) to last revision by HolyToaster

Joy-Con is the name for the Switch's primary game controllers. The controllers communicate to the console through bluetooth and can be disconnected from the main unit.

==Hardware==
The controllers themselves are simple to disassemble and identify.
[[File:JoyconFront.jpg|400px|thumb|The front of the Joy-Con internal[https://www.ifixit.com/Teardown/Nintendo+Switch+Teardown/78263]]]

|-
| Orange || STMicroelectronics NFCBEA 812006 33 (Likely NFC reader IC)
|-
| Yellow|| Macronix International MX25U4033E 4 Mb CMOS Flash
|}

==Firmware==
''See also: [[Joy-Con Firmware]]''

The firmware of the Joy-Cons seems to be generic across all instances. Details such as the handedness of the controller and the color is just indicated in a configuration part of the flash. Judging by quick glance at the firmware, it's probably identical to that used on the Pro Controller as well.

|-
| Joy-Con Left (Blue) || [[:File:pad.L.bin|flash dump]]
|-
| Joy-Con Right (Red) || [[:File:pad.R.bin|flash dump]]
|}
The flash is in a patch-ram format. Tools for dealing with it are available [https://github.com/shuffle2/nxpad].
A dump of the ROM region (taken while firmware was running) can be found [[:File:bcm20734_rom.bin|here]]. Note this is the same SoC used on the other controller models, as well.

== Left & Right Separate Joy-con ==

When paired directly to a computer over bluetooth, the joy-con both provide identical HID input report descriptor. This does not appear to include motion controls, IR data, or NFC. They both behave as detached single-player controllers.

==Colors==
HEX codes for the colors shown in the "Controllers" menu of the Switch UI can be found in a Joy-con SPI dump starting at offset 0x6050. Body color is first followed by button color and each is 3 bytes long. These values are able to be re-written with any HEX color value to make the Joy-cons show up as different colors in the UI. The following is a list of official HEX colors recovered from SPI dumps.
{| class="wikitable"

Fuses

2018-04-16T10:34:23Z

Shuffle2: /* bootrom_ipatch */

The Nintendo Switch makes use of Tegra's fuse driver for a number of operations. This driver is mapped to physical address 0x7000F800 with a total size of 0x400 bytes and exposes several registers for fuse programming.

Registers from 0x7000F800 to 0x7000F800 + 0xFF can be used to directly program the hardware fuse array, while registers from 0x7000F800 + 0x100 (FUSE_CHIP_REG_START_OFFSET) to 0x7000F800 + 0x3FC (FUSE_CHIP_REG_END_OFFSET) represent cached values read from certain fuses.

== Registers ==
Below is a list of fuse driver registers used by the Switch's bootloaders.

|-
|}

Before fuse reading/writing the power down mode must be disabled.
FUSE_SENSE mode flushes programmed values into the [[Fuses#Cache_registers|cache registers]].

==== FUSE_REG_ADDR ====
This register takes the address of the fuse to be read/written/sensed.

==== FUSE_REG_READ ====
This register receives the value read from the fuse.

==== FUSE_REG_WRITE ====
This register takes the value to be written to the fuse.

==== FUSE_TIME_PGM2 ====
This register takes the fuse programming pulse (0xC0 == 19200 kHz).

==== FUSE_DIS_PGM ====
If set to 0x01, this register disables fuse programming.

==== FUSE_WRITE_ACCESS ====
If set to 0x01, this register disables software writes to the fuse driver registers.

== eFuses ==
The actual hardware fuses can be programmed through the fuse driver after enabling fuse programming.

Below is a list of common fuse indexes used by Tegra devices (and applicable to the Switch).
Note that the indexes are relative to the start of the fuse array and each element is a 4 byte word. A single fuse write operation always writes the same word at both fuse_array + 0 (PRIMARY_ALIAS) and fuse_array + 1 (REDUNDANT_ALIAS).

=== odm_reserved ===
The first bootloader only burns fuses in this region.
Both fuse indexes 0x3A (odm_reserved + 0x0C) and 0x3C (odm_reserved + 0x0E) are used for anti-downgrade control. These fuses will have their values cached into [[#FUSE_RESERVED_ODM6|FUSE_RESERVED_ODM6]] and [[#FUSE_RESERVED_ODM7|FUSE_RESERVED_ODM7]].

=== bootrom_ipatch ===
Tegra210 based hardware such as the Switch provides support for bootrom patches. The patch data is burned to the hardware fuse array using a specific format (see [https://gist.github.com/shuffle2/f8728159da100e9df2606d43925de0af shuffle2's ipatch decoder]). The bootrom reads these fuses in order to initialize the IPATCH hardware, which allows overriding data returned for code and data fetches done by BPMP.

The revision stored in FUSE_CP_REV indicates the unique set of values stored in ipatch fuses.

The following represents the patch data dumped from a Switch console:

The last 4 patches are exclusive to the Switch, while the remaining ones are often included in most Tegra210 based devices.

== Anti-downgrade ==
The first bootloader verifies [[#FUSE_RESERVED_ODM7|FUSE_RESERVED_ODM7]] to prevent downgrading.
How many fuses are expected to be burnt depends the device's unit type as below.

{| class="wikitable" border="1"
|-
! System version
! Expected number of burnt fuses (retail)
! Expected number of burnt fuses (non-retail)
|-
| 1.0.0
| 1
| 0
|-
| 2.0.0-2.3.0
| 2
| 0
|-
| 3.0.0
| 3
| 1
|-
| 3.0.1-3.0.2
| 4
| 1
|-
| 4.0.0-4.1.0
| 5
| 1
|-
| 5.0.0
| 6
| 1
|}

If too many fuses are burnt the bootloader will panic immediately.

If too few are burnt, the bootloader will enable fuse programming and write the expected value to fuse indexes 0x3A and 0x3C. Afterwards, fuse programming is disabled and the panic value 0x21 is written to PMC_SCRATCH200 register (0x7000EC40). Finally, the watchdog timer is initialized and programmed to force a reset.

On a subsequent boot, after the anti-downgrade fuses are checked again, the PMC_RST_STATUS register (0x7000E5B4) is checked and if set to 0x01 (watchdog reset) the PMC_SCRATCH200 register (0x7000EC40) will be checked for the panic value 0x21.
PMC_RST_STATUS will only be set back to 0 (power on reset) if the fuse count matches the new expected value, otherwise the system will panic.

Shuffle2: /* Session */

One symbol in USB-sysmodule is: "vtable for nn::usb::detail::UsbComplexTegra21x".

= usb:ds =
This is "nn::usb::ds::IDsService".

Used for Switch<>PC USB comms, aka Switch-as-device. This seems to only be usable in handheld-mode with the Switch directly connected to a host via an USB cable, not(?) in docked-mode.
This service is used during [[Factory Setup|factory setup]] by [[Manu Services|manu]].

This service session is used as an IPC [[IPC_Marshalling|domain]] by [[Manu Services|manu]]. All of these {get-session} commands also return an output u8 and the u32 <[[IPC_Marshalling|domainID]]>, for using those sessions as domains.

Initialization done by [[Manu Services|manu]]:
* Initial service init:
** Get service/etc.
** Uses [[#BindDevice]].
** Uses [[#BindClientProcess]].
** Uses [[#GetStateChangeEvent]].
** Uses [[#SetVidPidBcd]].
* Interface init:
** Uses [[#GetDsInterface]], then uses commands from that with the rest of the following.
** Uses [[#GetSetupEvent]].
** Uses [[#GetCtrlInCompletionEvent]].
** Uses [[#GetCtrlOutCompletionEvent]].
* Initializes two endpoints via using [[#GetDsEndpoint]] twice.

== Configuration ==
The following is the default USB config strings, while the usbds service isn't being used. All of the below configuration will reset to the defaults when all usbds-related sessions are closed. These can be set with [[#SetVidPidBcd]]. The default string for Product is loaded from [[Settings_services|settings]] config. The default is referred to by usb-sysmodule as "Dummy".
Product: Nintendo Switch
Manufacturer: Nintendo
SerialNumber: SerialNumber

The following is the default <code>lsusb -v {...}</code> output when the usbds service wasn't used.

The endpoints are configured using [[#GetDsEndpoint]], the total number of endpoints is the number of open [[#IDsEndpoint]] sessions. bInterfaceNumber is {0-based index for the enabled [[#IDsInterface]] session.} Some of the interface fields are configured using [[#GetDsInterface]].

Additional descriptors for use with interfaces and endpoints can't be configured with usbds, even though the former is used for the default HID interface. This seems to be the main(?) restriction with using usbds for Switch-as-arbitrary-devices. The device class fields can't be configured, interface class fields are set instead.

When usbds is in use where [[#SetVidPidBcd]] wasn't used, the VID/PID is 057e:3000.

== BindDevice ==
Takes an u32 ('''complexId'''). [[Manu_Services|Manu]] sends 0x02.

Binding more than once with the current session is not allowed. Once this command is used, the USB device will not be listed with <code>lsusb</code> until [[#EnableInterface]] is used.

Returns a not-found error when complexId isn't 0x02, for values 0x0-0x4 at least.

== BindClientProcess ==
Takes 1 copy-handle for the current process (0xFFFF8001).

== GetDsInterface ==
Takes 2 type-5 buffers and returns an [[#IDsInterface]]. [[Manu_Services|Manu]] sends a 0x09-byte command (e.g.: 0x09, 0x04, 0x04, 0x00, 0x00, 0xFF, 0xFF, 0xFF, 0x00) in the first buffer and a string ("usb") in the second buffer.

When the strlen output for the second buffer is >=0x40, size 0x40 is used instead for copying the string. This is the interface name, it's not sent over USB.

Returns an error when [[#BindDevice]] wasn't used.

Up to 4 interfaces can be used+[[#EnableInterface|enabled]].

Structure of the first buffer(this is the same as [http://libusb.sourceforge.net/api-1.0/structlibusb__interface__descriptor.html libusb__interface__descriptor]):
{| class="wikitable" border="1"
|-
! Offset || Size || Description
|-
| 0x0 || 0x1 || bLength. Must match 0x9.
|-
| 0x1 || 0x1 || bDescriptorType. Must match 0x4.
|-
| 0x2 || 0x1 || bInterfaceNumber. When 0x4, the bInterfaceNumber is automatically allocated(error will be thrown if no space). Otherwise, it's used directly and must be <=3.

|-
| 0x6 || 0x1 || bInterfaceSubClass
|-
| 0x7 || 0x1 || bInterfaceProtocol
|-
| 0x8 || 0x1 || iInterface. Ignored.
|}

Only the first 0x9-bytes are used.

== GetStateChangeEvent ==
Returns an event handle for when the state returned by [[#GetState]] changes. Signalled when Switch<->host USB comms change between started/stopped. USB cable connected/disconnected while at least 1 interface was enabled, or interface enabled/disabled while the USB cable was connected which then caused USB-comms state to change.

== GetState ==
No input. Returns an output u32. Returns an error when [[#BindDevice]] wasn't used.

Returns the current state. Values:
* 0: Initial state.
* 6: Device init starting.
* 3: {Initialization}, previous state is 6.
* 4: {Initialization}, previous state is 3.
* 5: Initialization done, data-transfer is now available.

== SetVidPidBcd ==
Takes a type-5 buffer with 0x66 bytes of USB descriptor data (see [[Manu_Services#manu|manu]]).

{| class="wikitable" border="1"
|-
! Offset || Size || Description
|-
| 0x0 || 0x2 || VID (idVendor)

| 0x6 || 0x20 || Manufacturer
|-
| 0x26 || 0x20 || Product
|-
| 0x46 || 0x20 || SerialNumber
|}

The last 3 blocks are ASCII strings. The data following each string is all-zero, for padding to size 0x20.

== IDsInterface ==
This is "nn::usb::ds::IDsInterface".

|-
| 11 || [[#StallCtrl]] ||
|}

Commands cmd2, [[#CtrlInPostBufferAsync]], [[#CtrlOutPostBufferAsync]], and [[#StallCtrl]], will throw an error if the interface is not [[#EnableInterface|enabled]]. [[#GetDsEndpoint]] will throw an error if the interface is [[#EnableInterface|enabled]].

=== GetDsEndpoint ===
Takes a type-5 buffer and returns an [[#IDsEndpoint]]. [[Manu_Services|Manu]] uses this twice for getting two endpoint sessions, with the following 0x7-byte buffer data:
* First endpoint: 0x07, 0x05, 0x80, 0x02, 0x00, 0x02, 0x00
** bLength=0x7
** bDescriptorType=LIBUSB_DT_ENDPOINT
** bEndpointAddress=LIBUSB_ENDPOINT_IN
** bmAttributes=LIBUSB_TRANSFER_TYPE_BULK
** wMaxPacketSize=0x200
** bInterval=0
* Second endpoint: Same as above except byte2 is 0x00(bEndpointAddress=LIBUSB_ENDPOINT_OUT).

Each field is an u8, except for offset 0x4-0x5 which is an u16.

This structure matches [http://libusb.sourceforge.net/api-1.0/structlibusb__endpoint__descriptor.html libusb_endpoint_descriptor], with audio-only-devices fields bRefresh and bSynchAddress removed.

The buffer size must be >=0x7. Only the first 0x7-bytes from the buffer are used.
* Byte0(bLength) must match 0x7.
* Byte1(bDescriptorType) must match 0x5.
* Byte2(bEndpointAddress) is only compared with 0x80 to determine whether to use an input or output endpoint, the actual endpoint-number is allocated automatically by checking state. Hence, all input endpoints must use bEndpointAddress==0x80. Up to endpoint-number 0xF can be allocated for each endpoint-direction, for a total of 16 endpoints including control, and 15 for non-control endpoints([[#IDsEndpoint]] sessions for each direction). This matches the Tegra maximum.

From the Tegra datasheet: "The maximum packet size supported on any endpoint is 1024 bytes in high-speed mode, for both device and host modes."

=== GetSetupEvent ===
Returns an event handle. Unknown what triggers signalling, not signalled during interface-enable / device<>host USB-comms init.

=== EnableInterface ===
Takes no arguments. Enables the current interface.

Only one interface can be enabled at a time per bInterfaceNumber. When bInterfaceNumber is auto-allocate(0x4) for [[#GetDsEndpoint]] this isn't an issue since the final bInterfaceNumber will be unique.

Once enabled, the device/interface can then actually be used over USB.

=== DisableInterface ===
Takes no arguments. Disables the current interface.

=== CtrlInPostBufferAsync ===
Same as [[#PostBufferAsync]](with same input/output), except this uses control input endpoint 0x80.

=== CtrlOutPostBufferAsync ===
Same as [[#PostBufferAsync]](with same input/output), except this uses control output endpoint 0x00.

=== GetCtrlInCompletionEvent ===
Returns an event handle for polling the completion of input control commands. Same as [[#GetCompletionEvent]], except this uses control input endpoint 0x80.

=== GetCtrlInReportData ===
Same as [[#GetReportData]](with same input/output), except this uses control input endpoint 0x80.

=== GetCtrlOutCompletionEvent ===
Returns an event handle for polling the completion of output control commands. Same as [[#GetCompletionEvent]], except this uses control output endpoint 0x00.

=== GetCtrlOutReportData ===
Same as [[#GetReportData]](with same input/output), except this uses control output endpoint 0x00.

=== StallCtrl ===
No input/output.

Calls a function with both control endpoints(0x80 and 0x00) with the same function. From strings: "m_pProtocol->Stall(0x80)" "m_pProtocol->Stall(0x00)".

=== IDsEndpoint ===
This is "nn::usb::ds::IDsEndpoint".

|}

==== PostBufferAsync ====
Takes an u32 ('''size''') and an u64 ('''buffer'''). Returns an output u32 ('''urbId'''). The output urbId can then be used while parsing the output of [[#GetReportData]], after waiting for the CompletionEvent to be signalled.

The buffer address must be 0x1000-byte aligned. The input size doesn't matter.

Used for data-transfer with input/output endpoints.

The user-process must flush dcache for the buffer before using this command.

When sending data where size is larger than wMaxPacketSize, it will automatically send multiple USB packets where last packet size = {remaining size}. Every {wMaxPacketSize}-bytes is a different packet. This only occurs in some cases. When '''size''' is ~0x1000000(exact size unknown), Switch-side silently hangs, while host-side will timeout(no traffic on USB bus indicating failure).

For receiving data, if size is less than {actual received USB packet size} the rest of the packet will be discarded. Later PostBufferAsync cmd(s) will only return data from new packets, not the remainder of the earlier packet(s).

==== GetCompletionEvent ====
No input. Returns an output event handle for polling the completion of [[#PostBufferAsync]], even when it finished via [[#Stall]].

==== GetReportData ====
No input. Returns 0x84 bytes of report data from the endpoint. Seems to be eventually loaded from state, since this doesn't trigger any USB bus activity. All-zero before PostBufferAsync was used at least once.

=== Hardware Types ===

nx-abcb is the SDEV unit. Among other differences, this has extra hardware to support HDMI output.

nx-abca2 hardware types are variations of the retail form factor.

=== Notes ===

SPL uses id3 for setting up the security engine IRQ.

[[NIM_services|NIM]] checks that id8 output must match the [[Settings_services|set:cal]] DeviceId with byte7 cleared, otherwise panic.

[3.0.0+] [[Loader services|RO]] checks id11, if set then skipping NRR rsa signatures is allowed.

Kernel uses id11 to determine behavior of svcBreak positive arguments. It will break instead of just force-exiting the process which is what happens on retail. [2.0.0+] This is also used with certain debug [[SVC|SVCs]].

Kernel reads id12 when setting up memory-related code. If bit0 is set, it will memset various allocated memory-regions with 0x58, 0x59, 0x5A ('X', 'Y', 'Z') instead of zero. This allows Nintendo devs to find uninitialized memory bugs. If bit17-16 is 0b01, the kernel assumes 6GB of DRAM instead of 4GB.

== UserExpMod ==
Takes one type-10 (C descriptor) buffer ('''data_out_buf''') and 3 type-9 (X descriptor) buffers ('''data_in_buf''', '''exp_in_buf''' and '''mod_in_buf''').

Performs asymmetric crypto with user supplied modulus and exponent.

== GenerateAesKek ==
Takes a 16-byte EKS ('''Encryption Key Source''') and two words ('''KeyGeneration''' and '''option''') as input.
'''KeyGeneration''' ranges from 0 to 2.

Returns a scrambled sealed KEK ('''Key Encryption Key''' used as '''key_x''').

== LoadAesKey ==
Takes a u32 ('''keyslot''') and two 16-byte keys ('''key_x''' and '''key_y''').

Sets the specified '''keyslot''' with a key generated from '''key_x''' and '''key_y'''.

[2.0.0+] Now verifies that the engine in use (0..3) is locked/owned by the current spl session, otherwise errors with 0xD21A. Previously engine was hardcoded to 0.

== GenerateAesKey ==
Takes a 16-byte KEK ('''key_x''') and a 16-byte encrypted key ('''enc_key''').

Generates a new key by decrypting '''enc_key''' with a key generated from the supplied '''key_x''' and a fixed '''key_y'''.

[2.0.0+] Previously, it always used engine 0. Now it tries to allocate an engine to be used and returns 0xD01A if they're all busy. When the command is done, the engine is released.

== SetConfig ==
Takes a u32 ('''ConfigItem''') and a u64 ('''ConfigVal''').

Any other '''ConfigItem''', besides 13, can't be set.

== DecryptImportPrivkForRsaOaep ==
Takes one type-9 (X descriptor) buffer ('''enc_privk_in_buf'''), a 16-byte KEK ('''key_x'''), a 16-byte key ('''key_y''') and a u32 ('''version''').
'''version''' is 0 for normal keys or 1 for extended keys.

Decrypts '''enc_privk_in_buf''' with a key generated from '''key_x''' and '''key_y''' and imports it for later usage.

== DecryptRsaOaep ==
Takes one type-10 (C descriptor) buffer ('''data_out_buf''') and 3 type-9 (X descriptor) buffers ('''data_in_buf''', '''mod_in_buf''' and '''label_hash_in_buf''').

Decrypts '''data_in_buf''' into '''data_out_buf''' using the private key imported with [[#DecryptImportPrivkForRsaOaep]] and the supplied '''mod_in_buf'''. Afterwards, verifies RSA-OAEP encoding using '''label_hash_in_buf'''.

Returns an u32 ('''dec_data_size''').

== IsDevelopment ==
No input params.

Uses [[#GetConfig]] internally with id=6. Returns true if output from that is 0, or if the SMC returned error 2.

Returns an u8 flag for whether the system is devunit. Output flag is 0 on retail.

== GenerateSpecificAesKey ==
Takes a 16-byte seed ('''key_seed''') and two words ('''KeyGeneration''' and '''option''') as input.
'''KeyGeneration''' ranges from 0 to 2.

Returns a scrambled key ('''key_a''').

== DecryptPrivk ==
Takes one type-10 (C descriptor) buffer ('''dec_privk_out_buf'''), one type-9 (X descriptor) buffer ('''enc_privk_in_buf'''), a 16-byte KEK ('''key_x'''), a 16-byte key ('''key_y''') and a u32 ('''version''').
'''version''' is 0 for normal keys or 1 for extended keys.

Decrypts '''enc_privk_in_buf''' into '''dec_privk_out_buf''' with a key generated from '''key_x''' and '''key_y'''.

Used by [[SSL_services|SSL]]-sysmodule for TLS client-privk.

== DecryptAesKey ==
Takes a 16-byte encrypted key ('''enc_key''') and two words ('''KeyGeneration''' and '''option''') as input.
'''KeyGeneration''' ranges from 0 to 2.

Decrypts '''enc_key''' with a key generated from fixed '''key_x''' and '''key_y''' and returns a 16-byte decrypted key ('''dec_key''').

[2.0.0+] Introduced same engine allocation code as for [[#GenerateAesKey]].

== DecryptAesCtr ==
Takes a type-0x46 (B descriptor) buffer ('''data_out_buf'''), a u32 ('''keyslot'''), a type-0x45 (A descriptor) buffer ('''data_in_buf''') and a 16-byte CTR ('''aes_ctr''').

Decrypts '''data_in_buf''' into '''data_out_buf''' using the key set in the specified '''keyslot'''.

[2.0.0+] Verifies the engine is locked by current session.

== ComputeCmac ==
Takes one type-9 (X descriptor) buffer ('''data_in_buf''') and a u32 ('''type?''').

Returns a 16-byte CMAC calculated over '''data_in_buf'''.

[2.0.0+] Verifies the engine is locked by current session.

== DecryptImportPrivkForExpMod1 ==
Takes one type-9 (X descriptor) buffer ('''enc_privk_in_buf'''), a 16-byte KEK ('''key_x'''), a 16-byte key ('''key_y''') and a u32 ('''version''').
'''version''' is 0 for normal keys or 1 for extended keys.

Decrypts '''enc_privk_in_buf''' with a key generated from '''key_x''' and '''key_y''' and imports it for later usage.

== UnwrapRsaWrappedTitleKey ==
Takes 3 type-9 (X descriptor) buffers ('''data_in_buf''', '''mod_in_buf''' and '''param0_in_buf''').

Decrypts '''data_in_buf''' using the private key imported with [[#DecryptImportPrivkForExpMod1]] and the supplied '''mod_in_buf''' and '''param0_in_buf'''.

Generates and returns a 16-byte sealed titlekey.

== LoadTitleKey ==
Takes a u32 ('''keyslot''') and a 16-byte sealed titlekey.

Sets the specified '''keyslot''' with the titlekey.

[2.0.0+] Verifies the engine is locked by current session.

== UnwrapAesWrappedTitleKey ==
Takes a 16-byte EKS ('''Encryption Key Source''').

Returns a sealed titlekey.

== LockAesEngine ==
Returns the id of the engine that was locked, or 0xD01A if all engines are busy. You need to lock an engine before using AES functions.

== UnlockAesEngine ==
Takes a single u32 and unlocks the engine with that id. It must be owned by current session otherwise 0xD21A will be returned.

== GetSplWaitEvent ==
Returns an event handle for synchronizing with the locked AES engine.

== SetSharedData ==
Sets a static dword in spl .bss to the user input u32.

[4.0.0+] returns 0xD41A if a value has been previously set without being [[#GetSharedData|gotten]].

== GetSharedData ==
Returns the static dword in spl .bss that can be set via [[#SetSharedData]].

[4.0.0+] returns 0xD61A if a value has not previously been set, and unsets the value after getting it.
