A character device file is associated\n with it.\n - fw_unit is a unit directory on a node. Each fw_device may have 0..n\n children of type fw_unit. The units tell us what kinds of protocols\n a node implements.\n\nWe want to set ownership or ACLs or permissions of the character device\nfile of an fw_device, or/and create symlinks to it, based on available\nprotocols. Until now udev rules had to look at the fw_unit devices and\nthen modify their parent\u0027s character device file accordingly. This is\nproblematic for two reasons: 1) It happens sometime after the creation\nof the fw_device, 2) an access policy may require that information from\nall children is evaluated before a decision about the parent is made.\n\nProblem 1) can ultimately not be avoided since this is the nature of\nFireWire nodes: They may add or remove unit directories at any point in\ntime.\n\nHowever, we can still help userland a lot by providing the protocol type\ninformation of all units in a summary sysfs attribute directly at the\nfw_device. This way,\n - the information is immediately available at the affected device\n when userspace goes about to handle an ADD or CHANGE event of the\n fw_device,\n - with most policies, it won\u0027t be necessary anymore to dig through\n child attributes.\n\nThe new attribute is called \"units\". It contains space-separated tuples\nof specifier_id and version of each present unit. The delimiter within\ntuples is a colon. Specifier_id and version are printed as 0x%06x.\n\nHere is an example of a node which implements an IPv4 unit and an IPv6\nunit: $ cat /sys/bus/firewire/devices/fw2/units\n0x00005e:0x000001 0x00005e:0x000002\n\nSigned-off-by: Stefan Richter \u003cstefanr@s5r6.in-berlin.de\u003e\n" }, { "commit": "e5333db9285e088a98f4bad5147bfb0b4665fafb", "tree": "10a46852f80d27a4eef4f51ae847c7c541c0fd07", "parents": [ "92368890d551794ee8d7e90477d8498bb7f82a9b" ], "author": { "name": "Stefan Richter", "email": "stefanr@s5r6.in-berlin.de", "time": "Fri May 22 23:16:27 2009 +0200" }, "committer": { "name": "Stefan Richter", "email": "stefanr@s5r6.in-berlin.de", "time": "Mon Jun 01 12:48:49 2009 +0200" }, "message": "firewire: core: check for missing struct update at build time, not run time\n\nstruct fw_attribute_group.attrs.[] must have enough room for all\nattributes.

I suspect that\nlower CPU scheduling latencies in newer kernels made this issue more\nprominent now.\n\nAccording to\nhttps://sourceforge.net/tracker/?func\u003ddetail\u0026atid\u003d114103\u0026aid\u003d2492640\u0026group_id\u003d14103\nthis can be fixed by configuring the FireWire controller for more\nhardware retries for request transmission; these retries are evidently\nmore successful than libavc1394\u0027s own retry loop (typically 3 tries on\ntop of hardware retries).\n\nPresumably the same issue has been reported at\nhttps://bugzilla.redhat.com/show_bug.cgi?id\u003d449252 and\nhttps://bugzilla.redhat.com/show_bug.cgi?id\u003d477279 .\n\nIn a quick test with a JVC camcorder (which didn\u0027t malfunction like the\nreported camcorders), this change decreased the number of ack_busy_X\nfrom 16 in three runs of dvgrab to 4 in three runs of the same capture\nduration.\n\nSigned-off-by: Stefan Richter \u003cstefanr@s5r6.in-berlin.de\u003e\n" }, { "commit": "b006854955254a971096c120d4ef115a7c6145fb", "tree": "91c3c3a50c8ed60464701893119d44f63b50f293", "parents": [ "3d36a0df3b473fb53531484df227f2da8bc7494b" ], "author": { "name": "Stefan Richter", "email": "stefanr@s5r6.in-berlin.de", "time": "Mon Jan 05 20:43:23 2009 +0100" }, "committer": { "name": "Stefan Richter", "email": "stefanr@s5r6.in-berlin.de", "time": "Sat Jan 24 11:17:27 2009 +0100" }, "message": "firewire: ohci: change \"context_stop: still active\" log message\n\nThe present message is mostly just noise.
