Kernel

• KPoolManager was majorly rewritten.
  • Per-page reference counting was removed.
  • 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 doesn't incref for each map.
  • Instead it maintains a list of every map (each 0x20-byte entry).
  • Probably to do better cleanup.

• 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.
  • Probaly 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.

• TLS pages are now allocated with a slabheap.
