At present, core function can handle node which has configuration ROM similar to standard AV/C device somehow. The standard layout of configuration ROM is described in the following document. - Configuration ROM for AV/C Devices 1.0 (Dec. 12, 2000, 1394 Trading Association) This commit adds a KUnit test for the above case. The following output is the parse result for the hard-coded data, by config-rom-pretty-printer in linux-firewire-utils (https://git.kernel.org/pub/scm/utils/ieee1394/linux-firewire-utils.git/). $ config-rom-pretty-printer < /tmp/rom.img ROM header and bus information block ----------------------------------------------------------------- 1024 0404eabf bus_info_length 4, crc_length 4, crc 60095 1028 31333934 bus_name "1394" 1032 e0646102 irmc 1, cmc 1, isc 1, bmc 0, cyc_clk_acc 100, max_rec 6 (128) 1036 ffffffff company_id ffffff | 1040 ffffffff device_id 1099511627775 | EUI-64 18446744073709551615 root directory ----------------------------------------------------------------- 1044 00063287 directory_length 6, crc 12935 1048 03ffffff vendor 1052 8100000a --> descriptor leaf at 1092 1056 17ffffff model 1060 8100000e --> descriptor leaf at 1116 1064 0c0083c0 node capabilities: per IEEE 1394 1068 d1000001 --> unit directory at 1072 unit directory at 1072 ----------------------------------------------------------------- 1072 0004442d directory_length 4, crc 17453 1076 1200a02d specifier id 1080 13010001 version 1084 17ffffff model 1088 81000007 --> descriptor leaf at 1116 descriptor leaf at 1092 ----------------------------------------------------------------- 1092 0005c915 leaf_length 5, crc 51477 1096 00000000 textual descriptor 1100 00000000 minimal ASCII 1104 56656e64 "Vend" 1108 6f72204e "or N" 1112 616d6500 "ame" descriptor leaf at 1116 ----------------------------------------------------------------- 1116 00057f16 leaf_length 5, crc 32534 1120 00000000 textual descriptor 1124 00000000 minimal ASCII 1128 4d6f6465 "Mode" 1132 6c204e61 "l Na" 1136 6d650000 "me" Link: https://lore.kernel.org/r/20231221134849.603857-5-o-takashi@sakamocchi.jp Signed-off-by: Takashi Sakamoto <o-takashi@sakamocchi.jp> |

README
Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
