==Secure Monitor== | |||
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: | |||
* smcLoadSecureExpModKey no longer exists. | |||
* smcLoadRsaOaepKey has been replaced with a new SMC (0xC300D60C) that loads two keys into TrustZone. | |||
* 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 | |||
* Getconfig(17) now checks whether package2 is plaintext or encrypted. | |||
