Package1

• The encrypted binaries' order and calculation for next stage's entrypoint was changed.

Old layout (before 2.0.0):

1.- PK11 header
2.- Secure Monitor blob
3.- NX bootloader blob
4.- Warmboot blob

NX bootloader entrypoint is calculated as:
0x40013FE0 + 0x20 + 0x20 + NX bootloader blob's offset + Secure Monitor blob's size

New layout (2.0.0+):

1.- PK11 header
2.- Warmboot blob
3.- NX bootloader blob
4.- Secure Monitor blob

NX bootloader entrypoint is calculated as:
0x40013FE0 + 0x20 + 0x20 + NX bootloader blob's offset + Warmboot blob's size

• Some AES-ECB decryption related code was refactored.

System Titles

• Every system module was updated.
  • The creport system module (0100000000000036) was added.
• Every system applet was updated.
• Every 01000000000008XX title was updated except for:
  • 0100000000000805(CHN/KOR dictionary), 0100000000000808("European, English and Japanese dictionaries"), 010000000000080A(Chara?), and 010000000000080C(EULA).
• The following 01000000000008XX titles were added:
  • 0100000000000800(SSL trusted certs), 0100000000000807(Hotspot List), 010000000000081E(Dummy file), 010000000000081F(Icosa system config), 0100000000000820(Copper system config), 0100000000000821(Hoag system config)
• 010000000000081B ("exFAT FIRM") package2 is no longer "stubbed"/overwritten with garbage.

Kernel

• KPoolManager was majorly rewritten.
  • Added MAC crypto on heap-chunk headers, to protect against DMA attacks (same as 3DS).

• KHandleTable default size was improved from 40 to 1024.
• The code to create a bigger handle table in allocated pool memory has been removed.
• KHandleTable spinlock was given core-suspension logic.
• KHandleTable compresses 64-bit pointers into 32-bit offsets.

• KAddressSpace was renamed to KDeviceAddressSpace.

• KSharedMemory now maintains a list of every map (each 0x20-byte entry).
  • To do cleanup of mapped shared memories when a process is killed.

• KSharedMemory no longer references the owning KProcess.
  • Instead it stores the pid, so that the process can be freed even though the shared memory still exists.

• KInterruptEvent changed:
  • Creation doesn't use KIrqSingleton directly anymore.
  • Instead it allocates a 0x20-byte entry, and then uses KIrqSingleton.
  • Probably to do better cleanup.

• Size-checks >= 0x180000000 was added to a bunch of syscalls.

• Restriction on debug SVCs were loosened to support creport.

• svcReadWriteRegister was extended with more registers.

• Added blacklist on NPDM kernel descriptor memory mappings.

• svcGetInfo was extended with more id0's.

• Process exception dispatching was implemented/improved.

• Support for processes with 39-bit AddressSpaceType was added.
  • Includes required IPC changes.

• On startup, kernel now calls SMC id1 0xC3000007 with the kernel memory range start and size.

• AArch64 exception vector for "SError interrupt" was implemented.

• Kernel stacks are now allocated with a slabheap.

• While 1.0.0 had two pools with size 0, now it uses all three. The last one size is calculated dynamically to fit all the built-in sysmodules, and it's now protected by the kernel carveout.
