Detailed Description

CPU driver init code for ARMv7A cores.

Function Documentation

void arch_init	(	struct arm_core_data *	boot_core_data,
		struct armv7_boot_record *	bootrec
	)

Continue kernel initialization in kernel address space.

This function sets up exception handling, initializes devices and enables interrupts. After that it calls arm_kernel_startup(), which should not return (if it does, this function halts the kernel).

bool cpu_is_bsp

(

void

)

Is this the BSP?

Returns

True iff the current core is the bootstrap processor.

Variable Documentation

uintptr_t kernel_stack[KERNEL_STACK_SIZE/sizeof(uintptr_t)]

The kernel stack.

Declared in boot.S.
