Module conversions 

Calculation, conversion and rounding for memory related numbers.

Functions

address_to_chunk_index

Convert an address to the chunk index (aligned down).

bytes_to_chunks_up

Convert size in bytes to the number of chunks (aligned up).

bytes_to_formatted_string

Convert size in bytes to a readable short string, such as 1GB, 2TB, etc. It only keeps the major unit and keeps no fraction.

bytes_to_pages_up

Convert size in bytes to the number of pages (aligned up)

chunk_align_down

Align down an address to the nearest chunk.

chunk_align_up

Align up an address to the nearest chunk.

chunk_index_to_address

Convert a chunk index to the start address of the chunk.

is_address_aligned

Is the address aligned to word boundary?

is_page_aligned

Is the address aligned to page boundary?

mmap_chunk_align_down

Align down an address to the nearest chunk at which granularity we mmap memory.

mmap_chunk_align_up

Align up an address to the nearest chunk at which granularity we mmap memory.

page_align_down

Align down an address to the nearest page.

pages_to_bytes

Convert the number of pages to bytes.

raw_align_down

Align down an integer to the given alignment. align must be a power of two.

raw_align_up

Align up an integer to the given alignment. align must be a power of two.

raw_is_aligned

Is the integer aligned to the given alignment? align must be a power of two.

rshift_align_up

Shift num by bits to the right. Add 1 to the result if any 1 bits are shifted out to the right. This is equivalent to dividing num by 2 to the power of bits, rounding up.
