The built codebins now have padding in .text after every function for 0x10-byte alignment.

The built codebins now have padding in .text after every function for 0x10-byte alignment (and other compiler changes).

The SDK included with titles (main-codebin) for NV changed/updated NVIDIA hw strings:

Line 82:

A new folder "a" was added, in addition to the existing "nx" folder, containing a separate "bct" and "package1". Both of these seem encrypted/meant for the new "Mariko" hardware that support was added for.

~~The following firm-sysmodules was added to both safemode-firm, which were originally in separate sysmodule-titles: [[Bus_services|Bus]], [[PCV_services|PCV]], and [[PSC_services|psc]].~~

~~All firm-sysmodules were updated (might be due to updated (?) rtld).~~

====Secure Monitor====

Line 94:

Line 90:

In addition, there were changes to the [[SMC]] interface:

* smcGenerateSpecificAesKey was updated to support generating previous 4.x+ device key(s).

* smcLoadSecureExpModKey/smcLoadRsaOaepKey/smcDecryptRsaPrivateKey no longer exist.

* smcLoadRsaOaepKey was replaced with smcEncryptRsaPrivateKeyForImport.

** GetConfig(16), which seems to check whether the Switch is running on a Tegra 210:

return (FUSE_RESERVED_ODM4 & 0x800) && FUSE_RESERVED_ODM0 == 0x8E61ECAE && FUSE_RESERVED_ODM1 == 0xF2BA3BB2 ? (FUSE_RESERVED_ODM2 & 0x1F) : 0

** Getconfig(17), which returns the Package2 ~~meta fields (first 4 words)~~ if ~~package2 is plaintext~~.

** Getconfig(17), which returns the Package2 hash if booting from recovery mode.

Line 108:

Line 105:

* Kernel Address Space Layout Randomization was added.

** Instead of using a hardcoded address for per-CPU region, they now use x18 to point to the per-CPU region.

* When using most [[SMC]]s, IRQs are now disabled first then restored to original state afterwards. x18 is also reinitialized right after most SMCs (see above).

* 5 new syscalls.

** Syscalls 0x48+0x49 are used by [[AM_services|AM]]-sysmodule.

** Syscalls 0x48+0x49 (svcAllocateUserHeapMemory+svcFreeUserHeapMemory) are used by [[AM_services|AM]]-sysmodule.

** Syscall 0x4A is used by [[Process_Manager_services|PM]]-sysmodule.

*** This is used to allocate Application pool.

** Syscall 0x6F is used by FS, SM, and PM.

** Syscall 0x4A (svcSetUserHeapMemoryAllocationMax) is used by [[Process_Manager_services|PM]]-sysmodule.

*** This allows PM to set a limit on the number of bytes AM can allocate from Application pool.

** Syscall 0x6F (svcGetMemoryInfo) is used by FS, SM, and PM.

** Syscall 0x2E (svcGetNextThreadInfo) was added, but it only works on dev units.

*** Allows fetching how many bytes free/occupied by the different pools.

** svcControlCodeMemory was [[SVC#svcControlCodeMemory|updated]].

* NPDM irq_id's are no longer checked to be < 0x100, instead max-value is loaded from per-cpu state.

* The order slabheaps are laid out in memory is now randomized.

* There are now 4 memory pool partitions.

** This fixes sysmodule takeover with GMMU hax.

Line 148:

** "IcoPctl.bntx"

** "LogoMoon{region/language-text}.bntx", for every region/language.

New fields were added to [[Settings_services#System_Config|System Config]].
