The [[Memory_layout|Memory layout]] was changed significantly:
* .text, .rodata, and .data are now separate sections, instead of being mapped RWX.* Physical layout in TZRAM changed significantly, with pk2ldr being in low TZRAM instead of high TZRAM.
In addition, there were changes to the [[SMC]] interface:
** 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) now does the following, 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
now checks whether package2 is plaintext or encrypted.
