| + | ==== Version ==== |
| + | The current [[Package2#Versions|Package1 Maxver Constant]] - 1. |
| + | |
| + | ==== HardwareType ==== |
| + | [1.0.0+] This item is obtained by checking bits 8 and 2 from [[Fuse_registers#FUSE_RESERVED_ODM4|FUSE_RESERVED_ODM4]]. It can be: |
| + | * 0 ('''Icosa'''; Erista retail and EDEV), if development flag (bit 8) is '''Retail''' and production flag (bit 2) is '''Production'''. |

| + | ==== IsRetail ==== |
| + | This item is obtained by checking bits 9 and 0-1 from [[Fuse_registers#FUSE_RESERVED_ODM4|FUSE_RESERVED_ODM4]]. It can be 0 (Debug), 1 (Retail) or 2 (Invalid). |
| + | |
| + | ==== IsRecoveryBoot ==== |
| + | Used to determine if the system is booting from SafeMode firmware. |
| + | |
| + | Under normal circumstances, this just returns bit 0 of the active [[BCT#bootloader0_info|bootloader info]]'s attribute field. |
| + | |
| + | ==== DeviceId ==== |
| + | [[NIM_services|NIM]] checks if this item matches the [[Settings_services|set:cal]] DeviceId with byte7 cleared. If they don't match, a panic is thrown. |

| + | ==== MemoryArrange ==== |
| + | [[Process Manager services|PM]] uses this item for selecting the appropriate size for each [[SVC#LimitableResource|LimitableResource_Memory]]. |
| + | |
| + | ==== IsDebugMode ==== |
| + | Kernel uses this 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]]. |
| + | |
| + | [3.0.0+] [[Loader services|RO]] checks this and if set then skipping NRR rsa signatures is allowed. |
| + | |
| + | The value of this field is loaded from [[BootConfig]] unsigned-config+0x10 u8 bit1. |
| + | |
| + | ==== KernelConfiguration ==== |
| + | Kernel reads this when setting up memory-related code. |
| + | |
| + | Bit 0 is a boolean determining whether kernel should 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. |
| + | |
| + | Bit 1 is a boolean determining whether kernel should forcefully enable usermode exception handlers (when false, only certain aborts (((1LL << (esr >> 26)) & 0x1115804400224001) == 0, typically data/prefetch aborts) that occur when the faulting address is in a readable region with MemoryType_CodeStatic will trigger usermode exception handlers). |
| + | |
| + | Bit 2 is a boolean determining whether kernel should enable usermode access to the Performance Monitors (whether PMUSERENR_EL0 should be 1 or 0). |
| + | |
| + | [8.0.0+] Bit 3 is a boolean determining whether the kernldr should allocate 0x68000 extra bytes before INI1 data |
| + | |
| + | Bits 8-15 are a boolean determining whether kernel should call smcPanic on error instead of infinite-looping. |
| + | |
| + | Bits 16-17 determine how much memory is available. 00/03 = 4 GB, 01 = 6 GB, 02 = 8 GB. |
| + | |
| + | ==== IsChargerHiZModeEnabled ==== |
| + | This tells if the TI Charger (bq24192) is active. |
| + | |
| + | ==== KeyGeneration ==== |
| + | This item is obtained from [[Fuse_registers#FUSE_RESERVED_ODM2|FUSE_RESERVED_ODM2]] if bit 11 from [[Fuse_registers#FUSE_RESERVED_ODM4|FUSE_RESERVED_ODM4]] is set, [[Fuse_registers#FUSE_RESERVED_ODM0|FUSE_RESERVED_ODM0]] matches 0x8E61ECAE and [[Fuse_registers#FUSE_RESERVED_ODM1|FUSE_RESERVED_ODM1]] matches 0xF2BA3BB2. |
| + | |
| + | [5.0.0+] [[Filesystem services|FS]] can now use this value for the '''KeyGeneration''' parameter when calling [[#GenerateAesKek|GenerateAesKek]] during "GetBisEncryptionKey". |
| + | |
| + | ==== IsKiosk ==== |
| + | This item is bit 10 from [[Fuse_registers#FUSE_RESERVED_ODM4|FUSE_RESERVED_ODM4]]. |
| + | |
| + | [4.0.0+] [[Settings_services|Settings]] uses this value to overwrite the quest flag from [[Settings_services#set:sys|GetQuestFlag]]. This is used to detect if a Switch is a kiosk unit for display at retail stores. |
| + | |
| + | ==== RegulatorType ==== |
| + | This item is currently hardcoded to 0. |
| + | |
| + | [5.0.0+] [[PCV_services|PCV]] uses this value in combination with [[#HardwareType|HardwareType]] to configure power blocks and memory tables for different hardware. |

| + | This is a SHA-256 hash calculated over the [[Package2|package2]] image. Since the hash calculation is an optional step in pkg2ldr, this item is only valid in recovery mode. Otherwise, an error is returned instead. |
| + | |
| + | === GenerateRandomBytes === |
| + | Takes a '''size''' and returns '''rand_bytes'''. |
| + | |
| + | The kernel limits '''size''' to 0x38 (for fitting in return registers). |
| + | |
| + | === Panic === |
| + | Issues a system panic. |
| + | |
| + | The kernel always calls this with '''panic_color''' set to 0xF00. |
| + | |
| + | === ConfigureCarveout === |
| + | Configures memory controller carveout regions. |
| + | |
| + | If '''carveout_index''' is 0, '''region_phys_addr''' and '''region_size''' are used to configure '''MC_SECURITY_CARVEOUT4'''. |
| + | If '''carveout_index''' is 1, '''region_phys_addr''' and '''region_size''' are used to configure '''MC_SECURITY_CARVEOUT5'''. |
| + | Any other '''carveout_index''' values are invalid. |
| + | |
| + | The kernel calls this with '''carveout_index''' set to 0, '''region_phys_addr''' set to 0x80060000 and '''region_size''' set to a dynamically calculated size which covers all the kernel and built-in sysmodules' DRAM regions. |
| + | |
| + | === ReadWriteRegister === |
| + | Relays [[SVC#svcReadWriteRegister|svcReadWriteRegister]] to the Secure Monitor. |
