===FIRM===
====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.
==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.
* KHeapArrange was changed. On 1.0.0 it held address/size for three pools ("base", "application", "system") and application/system were zero-sized/unused. Now it holds "pool management", "secure", "non-secure". Pool management and secure are now protected by the kernel carveout.
** Secure pool size is dynamically calculated as size of all kips (including stacks) + 24 MB (FS sysmodule heap) + 1 MB (spare pages for e.g. IPC buffer usage).
** If only one KIP is present, all memory goes to secure pool and non-secure pool does not exist.
