Method Details

init(self, **kwargs)
(Constructor)

source code

Instantiate an Intel 32 bit Address space over the layered AS.

Args:
  dtb: The dtb address.

Overrides: object.__init__: (inherited documentation)

IDENTITY_FRAME(self, pfn)

source code

Returns the identity frame of pfn.

From http://lxr.free-electrons.com/source/arch/x86/include/asm/xen/page.h?v=3.8#L36

m2p(self, machine_address)

source code

Translates from a machine address to a physical address.

This translates host physical addresses to guest physical. Requires a machine to physical mapping to have been calculated.

read_pte(self, vaddr, collection=None)

source code

Returns an unsigned 64-bit integer from the address addr in physical memory. If unable to read from that location, returns None.

Overrides: intel.IA32PagedMemory.read_pte: (inherited documentation)

vtop(self, vaddr)

source code

Translates virtual addresses into physical offsets.

The function should return either None (no valid mapping) or the offset in physical memory where the address maps.

This function is simply a wrapper around describe_vtop() which does all the hard work. You probably never need to override it.

Overrides: addrspace.BaseAddressSpace.vtop: (inherited documentation)
