==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: | |||

===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. | |||
