Line 187:

The kernel always calls this with '''panic_color''' set to 0xF00.

=== ProtectKernelRegion ===

Configures memory controller carveout regions.

If '''carveout_index''' is 0, '''region_phys_addr''' and '''region_size''' are used to configure '''MC_SECURITY_CARVEOUT4'''.

If '''carveout_index''' is 1, '''region_phys_addr''' and '''region_size''' are used to configure '''MC_SECURITY_CARVEOUT5'''.

Any other '''carveout_index''' values are invalid.

The kernel calls this with '''carveout_index''' set to 0, '''region_phys_addr''' set to 0x80060000 and '''region_size''' set to a dynamically calculated size which covers all the kernel and built-in sysmodules' DRAM regions.

=== ReadWriteRegister ===

Relays [[SVC#svcReadWriteRegister|svcReadWriteRegister]] to the Secure Monitor.
