| /** |
| * print_hex_dump - print a text hex dump to syslog for a binary blob of data |
| * @level: kernel log level (e.g. KERN_DEBUG) |
| * @prefix_str: string to prefix each line with; |
| * caller supplies trailing spaces for alignment if desired |
| * @prefix_type: controls whether prefix of an offset, address, or none |
| * is printed (%DUMP_PREFIX_OFFSET, %DUMP_PREFIX_ADDRESS, %DUMP_PREFIX_NONE) |
| * @rowsize: number of bytes to print per line; must be 16 or 32 |
| * @groupsize: number of bytes to print at a time (1, 2, 4, 8; default = 1) |
| * @buf: data blob to dump |
| * @len: number of bytes in the @buf |
| * @ascii: include ASCII after the hex output |
| * |
| * Given a buffer of u8 data, print_hex_dump() prints a hex + ASCII dump |
| * to the kernel log at the specified kernel log level, with an optional |
| * leading prefix. |
| * |
| * print_hex_dump() works on one "line" of output at a time, i.e., |
| * 16 or 32 bytes of input data converted to hex + ASCII output. |
| * print_hex_dump() iterates over the entire input @buf, breaking it into |
| * "line size" chunks to format and print. |
| * |
| * E.g.: |
| * print_hex_dump(KERN_DEBUG, "raw data: ", DUMP_PREFIX_ADDRESS, |
| * 16, 1, frame->data, frame->len, true); |
| * |
| * Example output using %DUMP_PREFIX_OFFSET and 1-byte mode: |
| * 0009ab42: 40 41 42 43 44 45 46 47 48 49 4a 4b 4c 4d 4e 4f @ABCDEFGHIJKLMNO |
| * Example output using %DUMP_PREFIX_ADDRESS and 4-byte mode: |
| * ffffffff88089af0: 73727170 77767574 7b7a7978 7f7e7d7c pqrstuvwxyz{|}~. |
