'''EnableNonZeroFillMemory''' 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.
 +

'''EnableUserExceptionHandler''' 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).
 +
 
 +
'''PerformanceMonitoringUnit''' is a boolean determining whether kernel should enable usermode access to the Performance Monitors (whether PMUSERENR_EL0 should be 1 or 0).
 +
 
 +
'''EnableApplicationExtraThread''' is a boolean determining whether the kernel should increase the KThread slabheap capacity by 160. This also increases object capacities that are calculated based on number of threads.
 +
 
 +
'''CallShowErrorOnPanic''' is a boolean determining whether kernel should call smcPanic on error instead of infinite-looping.
 +
 
 +
'''MemorySize''' determines how much memory is available. 00/03 = 4 GB, 01 = 6 GB, 02 = 8 GB.

=== GetConfig ===
+
===== DeviceUniqueKeyGeneration =====
−
Takes a '''config_item''' and returns an associated '''config_val'''.
+
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.
   −
=== GetRandomBytes ===
+
[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.
   −
=== ProtectKernelRegion ===
+
=== SetKernelCarveoutRegion ===
−
Configures memory controller carveout regions.
+
Takes an u64 '''Index''', an u64 '''Address''' and an u64 '''Size'''. Returns [[#Result]].
   −
