TC Applied Technologies designed DiceII ASIC to adapt to two protocols.
One of the protocol is mLAN defined by Yamaha Corporation, and another
is own protocol. The DiceII ASIC adapted to mLAN protocol was used some
products by Yamaha and its child company, Steinberg.
The content of configuration ROM for the models has completely different
layout from the one defined by 1394 Trading Association.
This commit adds an udev rule for the models. At present, no driver is

TC Applied Technologies designed the series of ASIC for audio and music
data transmission in several types of communication bus. It's named as
Digital Interface Communication Engine (DICE). Four ASICs are known in
the series for IEEE 1394 bus; Dice II, TCD2210 (Dice Jr.), TCD2220 (Dice
Mini), and TCD3070 (DiceIII).
The content of configuration ROM in products based on DICE ASICs is
known against specification defined by 1394 Trading Association.
This commit adds database entries for models without any customization by
vendors. In TCAT specification, The value of GUID field is split to four
parts; 24-bit OUI, 8-bit category, 10-bit product ID, and 22-bit serial
number in the order. In the specification, the value of category field is
fixed to 0x04. The root directory includes leaf entries for vendor and
model names. Although the specifier_id field in unit directory differs
depending on vendors, the version field in unit directory is fixed to
0x000001. ALSA dice driver supports them, but expects userspace
application to control them.

Although in IEEE 1394 unit function list I have a plan to use slash sign
in name of property, current implementation of parser doesn't allow it.

can find usage of slash sign in name of property.

Current udev rules configures group owner of firewire character device
to video group, corresponding to nodes in IEEE 1394 in below cases:
1.the node with any unit for any minor version of IIDC version 1
specification defined by 1394 Trading Association
2.the node with any unit for specification defined by Point Grey Research
3.the node with any unit for AV/C device v1.0 defined by 1394 Trading
Association
4.the node with any unit for vendor-unique protocol defined by 1394
Trading Association
Nevertheless, case 3 and 4 can cover the node with any unit for audio
function as well. In the cases, it's convenient to assign audio group.
Additionally, some nodes are known to have layout different from
the specification defined by 1394 Trading Association. In the case,
it's required to add rules specific to them.
Furthermore, some nodes have no fields for vendor name and model name in
configuration ROM. In the case, it's required to add entries to hardware
database for users convenience.
For the above reasons, this commit adds rules to use information in
hardware database for known units in IEEE 1394. One database entry
corresponds to one unit. Two types of key are used to match the unit;
customized key from node context, kernel modalias of unit context.
The entry has the type of function, at least. Supplementally, it has
vendor and model names.
For your information, below statements with Python pyparsing module are
expected to parse all of the custom key and module alias in the list:
```
subsystem_prefix = pp.Literal('ieee1394:').suppress()
hex_to_int = lambda a: int(a[0], 16)
node_prefix = pp.Literal('node:').suppress()
prefixed_lower_hex = pp.Combine(pp.Literal('0x') + pp.Word(pp.srange('[a-z0-9]'), exact=6)).setParseAction(hex_to_int)
ven_in_node = pp.dictOf(pp.Literal('ven'), prefixed_lower_hex)
mo_in_node = pp.dictOf(pp.Literal('mo'), prefixed_lower_hex)
unit_in_node = pp.Group(prefixed_lower_hex + pp.Literal(':').suppress() + prefixed_lower_hex)
units_in_node = pp.Group(pp.Literal('units') + pp.ZeroOrMore(pp.Literal('*')).suppress() + unit_in_node + pp.ZeroOrMore(pp.Literal('*')).suppress())
node_parser = subsystem_prefix + node_prefix + ven_in_node + pp.Optional(mo_in_node) + units_in_node
higher_hex = pp.Word(pp.srange('[A-Z0-9]'), exact=8).setParseAction(hex_to_int)
ven_in_unit = pp.dictOf(pp.Literal('ven'), higher_hex)
mo_literal_in_unit = pp.dictOf(pp.Literal('mo'), higher_hex)
mo_in_unit = pp.dictOf(pp.Literal('mo'), higher_hex ^ pp.Literal('*'))
sp_in_unit = pp.dictOf(pp.Literal('sp'), higher_hex)
ver_in_unit = pp.dictOf(pp.Literal('ver'), higher_hex)
unit_parser = subsystem_prefix + ven_in_unit + mo_in_unit + sp_in_unit + ver_in_unit

The s390 PCI driver assigns the hotplug slot name from the
function_id attribute of the PCI device using a 8 char hexadecimal
format to match the underlying firmware/hypervisor notation.
Further, there's always a one-to-one mapping between a PCI
function and a hotplug slot, as individual functions can
hot plugged even for multi-function devices.
As the generic matching code will always try to parse the slot
name in /sys/bus/pci/slots as a positive decimal number, either
a wrong value might be produced for ID_NET_NAME_SLOT if
the slot name consists of decimal numbers only, or none at all
if a character in the range from 'a' to 'f' is encountered.
Additionally, the generic code assumes that two interfaces
share a hotplug slot, if they differ only in the function part
of the PCI address. E.g., for an interface with the PCI address
dddd:bb:aa.f, it will match the device to the first slot with
an address dddd:bb:aa. As more than one slot may have this address
for the s390 PCI driver, the wrong slot may be selected.
To resolve this we're adding a new naming schema version with the
flag NAMING_SLOT_FUNCTION_ID, which enables the correct matching
of hotplug slots if the device has an attribute named function_id.
The ID_NET_NAME_SLOT property will only be produced if there's
a file /sys/bus/pci/slots/<slotname> where <slotname> matches
the value of /sys/bus/pci/devices/.../function_id in 8 char
hex notation.

When this test is run in mkosi, the previously tested cgroup that we write
xattrs into and the root cgroup are the same.
Since the root cgroup is a live cgroup anyways (vs. the test cgroups which are
remade each time) let's generate the expected preference values from reading
the xattrs instead of assuming it will be NONE.

sd_device_monitor_filter_add_match_subsystem_devtype() now returns 1 to signify

udev_monitor_filter_add_match_subsystem_devtype() needs to return 0 as documented.
udev_monitor_filter_add_match_tag() is adjusted to match.
This makes gdm start successfully here again.
Before, it would just not boot, with nothing very obvious in the logs:

Replaces #19171.
The issue was introduced in the refactoring in 775ae35403.
We would pass an initialized value to a helper function. We would only *use*
it if it was initialized. But the mere passing of an unitialized variable is
UB, so let's not do that. This silences a gcc warning.
The old code was just fine, but gcc doesn't understand that max_brightness is
initialized. Let's rework it a bit to move some logic to the main function. Now
get_max_brightness() just retrieves and parses the attribute, and the main
function decides what to do with it.
