Function Documentation

static void* phys_to_cached

(

phys_addr_t

paddr

)

[inline, static]

Convert a physical address to a virtual pointer to cacheable memory.

Parameters:

paddr

A physical address.

Returns:

A virtual address in P1 corresponding to paddr.

Definition at line 57 of file addrspace.h.

static void* phys_to_uncached

(

phys_addr_t

paddr

)

[inline, static]

Convert a physical address to a virtual pointer to non-cacheable memory.

Parameters:

paddr

A physical address.

Returns:

A virtual address in P2 corresponding to paddr.

Definition at line 68 of file addrspace.h.

static phys_addr_t virt_to_phys

(

void *

vaddr

)

[inline, static]

Convert a virtual pointer to a physical address. vaddr must contain an address in either P1 or P2, for example one returned by phys_to_cached() or phys_to_uncached().

Parameters:

vaddr

A virtual address in P1 or P2.

Returns:

The physical address corresponding to vaddr.
