System Titles

All 01000000000010XX titles and most 01000000000008XX titles were updated. Some 8XX titles were just rebuilt with the new NCA crypto without actual RomFS-content changes.

  • 0100000000000824 provides configuration for the new "T214" SoC.
  • 0100000000000825 contains an empty "/blacklist.dat" file.
  • 0100000000000826 contains a 0x40-byte "/version" file, this is all-zero except for '0' at offset 0x20.

The only 8XX titles with actual changes are (besides sysver-title, see below for FIRM):

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:

FIRM

All FIRM titles were updated, and everything under RomFS was updated.

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, PCV, and psc.

Secure Monitor

The Memory layout was changed significantly:

• .text, .rodata, and .data are now separate sections, mapped with correct permissions (RX, RO, RW, respectively), instead of being mapped RWX.
• Physical layout in TZRAM changed significantly, with pk2ldr being in low TZRAM instead of high TZRAM, etc.

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.
• smcDecryptRsaPrivateKey was replaced with smcDecryptOrImportRsaPrivateKey.
  • All keys which were previously imported with specific keys now first call smcEncryptRsaPrivateKeyForImport with the appopriate enum member to get a sealed copy of the RSA key, then smcDecryptOrImportRsaPrivateKey to import/unseal the key when needed.
• smcGetConfig was extended with two new config items:
  • 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 hash if booting from recovery mode.

<fill in the rest later>

Kernel

• 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 SMCs, 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 (svcAllocateUserHeapMemory+svcFreeUserHeapMemory) are used by AM-sysmodule.
    • This is used to allocate Application pool.
  • Syscall 0x4A (svcSetUserHeapMemoryAllocationMax) is used by 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.
• 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.

Internet Browser

OSS/WebKit was updated.

In the NPDM, besides the RSA region the only changes were the kernel-release-version descriptor + {new ACID flag is set}.

In the "shareddata:/" title, the NROs are now compressed: "{name}.nro.lz4" instead of "{name}.nro".

qlaunch

RomFS changes:

• "/common/shader/VarietyOceanShader_Nx.arc.szs" updated
• "/lyt/common.szs" updated
• "/lyt/DummyGameA.szs" and "/lyt/DummyGame.szs" were removed.
• "/lyt/Entrance.szs" updated
• "/lyt/Eula.szs" added
• "/lyt/Flaunch.szs" updated
• "/lyt/Gift.szs" updated
• "/lyt/Interrupt.szs" updated
• "/lyt/Migration.szs" updated
• "/lyt/Notification.szs" updated
• "/lyt/Option.szs"
• "/lyt/ResidentMenu.szs"

• "/message/" Everything under here was updated.
• "/message/Ocean.msbp.szs" added
• "/sound/qlaunch_action.bksnd" and "/sound/qlaunch.bfsar" were updated.
• "/texture" Directory was added, which contains images for Nintendo Switch Parental Controls:
  • "IcoPctl.bntx"
  • "LogoMoon{region/language-text}.bntx", for every region/language.

System Config

New fields were added to System Config.

NPDM

New flags bit2/bit3 were added to the flags at ACID+0xC.

Keys

Keyblob 5 is now used, instead of 4. New NCA keydata is now used as well.
