align_address_to_page_start(cls, address)
Class Method

source code

Align the given address to the start of the page it occupies.

Parameters:

address (int) - Memory address.

Returns: int

Aligned memory address.

align_address_to_page_end(cls, address)
Class Method

source code

Align the given address to the end of the page it occupies. That is, to point to the start of the next page.

Parameters:

address (int) - Memory address.

Returns: int

Aligned memory address.

align_address_range(cls, begin, end)
Class Method

source code

Align the given address range to the start and end of the page(s) it occupies.

Parameters:

begin (int) - Memory address of the beginning of the buffer. Use None for the first legal address in the address space.
end (int) - Memory address of the end of the buffer. Use None for the last legal address in the address space.

Returns: tuple( int, int )

Aligned memory addresses.

get_buffer_size_in_pages(cls, address, size)
Class Method

source code

Get the number of pages in use by the given buffer.

Parameters:

address (int) - Aligned memory address.
size (int) - Buffer size.

Returns: int

Buffer size in number of pages.

do_ranges_intersect(begin, end, old_begin, old_end)
Static Method

source code

Determine if the two given memory address ranges intersect.

Parameters:

begin (int) - Start address of the first range.
end (int) - End address of the first range.
old_begin (int) - Start address of the second range.
old_end (int) - End address of the second range.

Returns: bool

True if the two ranges intersect, False otherwise.

pageSize

Page size in bytes. Defaults to 0x1000 but it's automatically updated on runtime when importing the module.

Get Method:: unreachable(cls) - Try to get the pageSize value on runtime.
