==== Package2Hash ====
[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.
 
===== DeviceUniqueKeyGeneration =====
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.


=== GenerateRandomBytes ===
[5.0.0+] [[Filesystem services|FS]] can now use this value for the '''KeyGeneration''' parameter when calling [[#GenerateAesKek|GenerateAesKek]] during "GetBisEncryptionKey".
Takes a '''size''' and returns '''rand_bytes'''.


The kernel limits '''size''' to 0x38 (for fitting in return registers).
===== Package2Hash =====
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.


=== Panic ===
=== ShowError ===
Issues a system panic.
Takes an u32 '''Color''' and issues a system panic.


The kernel always calls this with '''panic_color''' set to 0xF00.
The kernel always calls this with '''Color''' set to 0xF00.


=== ConfigureCarveout ===
=== SetKernelCarveoutRegion ===
Configures memory controller carveout regions.
Takes an u64 '''Index''', an u64 '''Address''' and an u64 '''Size'''. Returns [[#Result]].


If '''carveout_index''' is 0, '''region_phys_addr''' and '''region_size''' are used to configure '''MC_SECURITY_CARVEOUT4'''.
If '''Index''' is 0, '''Address''' and '''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'''.
If '''Index''' is 1, '''Address''' and '''Size''' are used to configure '''MC_SECURITY_CARVEOUT5'''.
Any other '''carveout_index''' values are invalid.
Any other '''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.
The kernel calls this with '''Index''' set to 0, '''Address''' set to 0x80060000 and '''Size''' set to a dynamically calculated size which covers all the kernel and built-in sysmodules' DRAM regions.


=== ReadWriteRegister ===
=== ReadWriteRegister ===
Takes an u64 '''Register''', an u32 '''Mask''' and an u32 '''InValue'''. Returns [[#Result]] and an u32 '''OutValue'''.
Relays [[SVC#svcReadWriteRegister|svcReadWriteRegister]] to the Secure Monitor.
