| def | __init__ (self, base, config, dtb=0, skip_as_check=False, args, kwargs) |
| def | is_user_page (self, entry) |
| True if the page is accessible to ring 3 code. | |
| def | is_supervisor_page (self, entry) |
| True if the page is /only/ accessible to ring 0 code. | |
| def | is_writeable (self, entry) |
| True if the page can be written to. | |
| def | is_dirty (self, entry) |
| True if the page has been written to. | |
| def | is_nx (self, entry) |
| True if the page /cannot/ be executed. | |
| def | is_accessed (self, entry) |
| True if the page has been accessed. | |
| def | is_copyonwrite (self, entry) |
| True if the page is copy-on-write. | |
| def | is_prototype (self, entry) |
| True if the page is a prototype PTE. | |
| def | load_dtb (self) |
| Loads the DTB as quickly as possible from the config, then the base, then searching for it. | |
| def | __getstate__ (self) |
| def | vtop (self, addr) |
| Abstract function that converts virtual (paged) addresses to physical addresses. | |
| def | get_available_pages (self) |
| A generator that returns (addr, size) for each of the virtual addresses present, sorted by offset. | |
| def | get_available_allocs (self) |
| def | get_available_addresses (self) |
| A generator that returns (addr, size) for each valid address block. | |
| def | is_valid_address (self, vaddr) |
| Returns whether a virtual address is valid. | |

| def | __init__ (self, base, config, args, kwargs) |
| def | translate (self, vaddr) |
| def | get_available_allocs (self) |
| A generator that returns (addr, size) for each of the virtual addresses present, sorted by offset. | |
| def | calculate_alloc_stats (self) |
| Calculates the minimum_size and alignment_gcd to determine "virtual allocs" when read lengths of data It's particularly important to cast all numbers to ints, since they're used a lot and object take effort to reread. | |
| def | read (self, addr, length) |
| This method reads 'length' bytes from the specified 'addr'. More... | |
| def | zread (self, addr, length) |
| This method reads 'length' bytes from the specified 'addr'. More... | |

| def | __init__ (self, base, config, _args, _kwargs) |
| base is the AS we will be stacking on top of, opts are options which we may use. | |
| def | get_config (self) |
| Returns the config object used by the vm for use in other vms. | |
| def | is_valid_profile (self, profile) |
| Determines whether a selected profile is compatible with this address space. | |
| def | as_assert |
| Duplicate for the assert command (so that optimizations don't disable them) More... | |
| def | __eq__ (self, other) |
| def | __ne__ (self, other) |
| def | read (self, addr, length) |
| Read some data from a certain offset. | |
| def | zread (self, addr, length) |
| Read data from a certain offset padded with where data is not available. | |
| def | get_available_addresses (self) |
| Return a generator of address ranges as (offset, size) covered by this AS sorted by offset. More... | |
| def | is_valid_address (self, _addr) |
| Tell us if the address is valid. | |
| def | write (self, _addr, _buf) |
| def | __getstate__ (self) |
| Serialise this address space efficiently. | |
| def | __setstate__ (self, state) |
| def | address_mask (cls, addr) |
| Masks an address value for this address space. | |
| def | address_compare (cls, a, b) |
| Compares two addresses, a and b, and return -1 if a is less than b, 0 if they're equal and 1 if a is greater than b. | |
| def | address_equality (cls, a, b) |
| Compare two addresses and returns True if they're the same, or False if they're not. | |
| def | physical_space (self) |
| Return the underlying physical layer, if there is one. More... | |
