[Pdbg] [PATCH v6 0/5] hexdump bytes from getmem/getmemio

[Amitay Isaacs]

If the output of getmem/getmemio contains non-printable characters,
then dump output using hexdump format.  Otherwise dump raw bytes.

To force the raw output add command-line flag --raw to getmem/getmemio.

V2 changes:
  - If the memory is printable, output directly instead of using hexdump

V3 changes:
  - Print the addresses aligned to 16 bytes in hexdump
  - Add hexdump tests for grouping and aligntment

V4 changes:
  - work around isprint()

V5 changes:
  - Also ignore 0x0 as printable character
    This is useful when testing putmem/getmem on skiboot console.

V6 changes:
  - Add command-line flag --raw to getmem/getmemio
    Update usage docs for getmem/getmemio


Amitay Isaacs (5):
  main: Add hexdump() function to dump bytes
  tests: Add tests for hexdump()
  mem: Dump memory only if mem_read was successful
  main: Use hexdump to dump memory from gemem/getmemio
  mem: CR and LF are printable characters
