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.
