There was one attempt a year ago done by me to drop HAL [1] but it was never resolved. There was another time when Dan suggested to drop HAL driver [2] but it was decided to keep it around in case device assignment will be implemented for FreeBSD and the fact that virt-manager uses node device driver [3]. I checked git history and code and it doesn't look like bhyve supports device assignment so from that POV it should not block removing HAL. The argument about virt-manager is not strong as well because libvirt installed from FreeBSD packages doesn't have HAL support so it will not affect these users as well [4]. The only users affected by this change would be the ones compiling libvirt from GIT on FreeBSD. I looked into alternatives and there is libudev-devd package on FreeBSD but unfortunately it doesn't work as it doesn't list any devices when used with libvirt. It provides libudev APIs using devd. I also looked into devd directly and it provides some APIs but there are no APIs for device monitoring and events so that would have to be somehow done by libvirt. Main motivation for dropping HAL support is to replace libdbus with GLib dbus implementation and it cannot be done with HAL driver present in libvirt because HAL APIs heavily depends on symbols provided by libdbus.

The @destination, @path, @iface - * and @member parameters identify the object method to - * be invoked. The optional @replyout parameter will be - * filled with any reply to the method call. The method - * can be later invoked using virDBusCall. - * - * The @types parameter is a DBus signature describing - * the method call parameters which will be provided - * as variadic args. Each character in @types must - * correspond to one of the following DBus codes for - * basic types: - * - * 'y' - 8-bit byte, promoted to an 'int' - * 'b' - bool value, promoted to an 'int' - * 'n' - 16-bit signed integer, promoted to an 'int' - * 'q' - 16-bit unsigned integer, promoted to an 'int' - * 'i' - 32-bit signed integer, passed as an 'int' - * 'u' - 32-bit unsigned integer, passed as an 'int' - * 'x' - 64-bit signed integer, passed as a 'long long' - * 't' - 64-bit unsigned integer, passed as an 'unsigned long long' - * 'd' - 8-byte floating point, passed as a 'double' - * 's' - NUL-terminated string, in UTF-8 - * 'o' - NUL-terminated string, representing a valid object path - * 'g' - NUL-terminated string, representing a valid type signature - * - * or use one of the compound types - * - * 'a' - array of values - * 'v' - a variadic type. - * '(' - start of a struct - * ')' - end of a struct - * '{' - start of a dictionary entry (pair of types) - * '}' - start of a dictionary entry (pair of types) - * - * At this time, there is no support for Unix fd's ('h'), which only - * newer DBus supports. - * - * Passing values in variadic args for basic types is - * simple, the value is just passed directly using the - * corresponding C type listed against the type code - * above. Note how any integer value smaller than an - * 'int' is promoted to an 'int' by the C rules for - * variadic args. - * - * Passing values in variadic args for compound types - * requires a little further explanation. - * - * - Variant: the first arg is a string containing - * the type signature for the values to be stored - * inside the variant. This is then followed by - * the values corresponding to the type signature - * in the normal manner. - * - * - Array: when 'a' appears in a type signature, it - * must be followed by a single type describing the - * array element type. For example 'as' is an array - * of strings. 'a(is)' is an array of structs, each - * struct containing an int and a string. - * - * The first variadic arg for an array, is an 'int' - * specifying the number of elements in the array. - * This is then followed by additional variadic args, - * one for each element of the array. - * - * - Array reference: when 'a' appears in a type signature, - * followed by '&', this signifies an array passed by - * reference. - * - * Array references may only be used when the - * element values are basic types, or a dict - * entry where both keys and values are using - * the same basic type. - * - * The first variadic arg for an array, is an 'int' - * specifying the number of elements in the array. - * When the element is a basic type, the second - * variadic arg is a pointer to an array containing - * the element values. When the element is a dict - * entry, the second variadic arg is a pointer to - * an array containing the dict keys, and the - * third variadic arg is a pointer to an array - * containing the dict values. - * - * - Struct: when a '(' appears in a type signature, - * it must be followed by one or more types describing - * the elements in the array, terminated by a ')'. - * - * - Dict entry: when a '{' appears in a type signature it - * must be followed by exactly two types, one describing - * the type of the hash key, the other describing the - * type of the hash entry. The hash key type must be - * a basic type, not a compound type. - * - * Example signatures, with their corresponding variadic - * args: - * - * - "biiss" - some basic types - * - * (true, 7, 42, "hello", "world") - * - * - "as" - an array with a basic type element - * - * (3, "one", "two", "three") - * - * - "a(is)" - an array with a struct element - * - * (3, 1, "one", 2, "two", 3, "three") - * - * - "svs" - some basic types with a variant as an int - * - * ("hello", "i", 3, "world") - * - * - "svs" - some basic types with a variant as an array of ints - * - * ("hello", "ai", 4, 1, 2, 3, 4, "world") - * - * - "a{ss}" - a hash table (aka array + dict entry) - * - * (3, "title", "Mr", "forename", "Joe", "surname", "Bloggs") - * - * - "a{sv}" - a hash table (aka array + dict entry) - * - * (3, "email", "s", &quot;joe(a)blogs.com&quot;, "age", "i", 35, - * "address", "as", 3, "Some house", "Some road", "some city") - */ -int virDBusCreateMethodV(DBusMessage **call, - const char *destination, - const char *path, - const char *iface, - const char *member, - const char *types, - va_list args) -{ - if (!(*call = dbus_message_new_method_call(destination, - path, - iface, - member))) { - virReportOOMError(); - return -1; - } - - if (virDBusMessageEncodeArgs(*call, types, args) < 0) { - virDBusMessageUnref(*call); - *call = NULL; - return -1; - } - - return 0; -} - - -/** - * virDBusCreateMethod: - * @call: pointer to be filled with a method call message - * @destination: bus identifier of the target service - * @path: object path of the target service - * @iface: the interface of the object - * @member: the name of the method in the interface - * @types: type signature for following method arguments - * @...: method arguments - * - * See virDBusCreateMethodV for a description of the - * behaviour of this method. - */ -int virDBusCreateMethod(DBusMessage **call, - const char *destination, - const char *path, - const char *iface, - const char *member, - const char *types, ...) -{ - va_list args; - int ret; - - va_start(args, types); - ret = virDBusCreateMethodV(call, destination, path, - iface, member, types, args); - va_end(args); - - return ret; -} - - -/** - * virDBusCreateReplyV: - * @reply: pointer to be filled with a method reply message - * @types: type signature for following method arguments - * @args: method arguments - * - * This creates a DBus method reply message and saves a - * pointer to it in @reply. - * - * The @types parameter is a DBus signature describing - * the method call parameters which will be provided - * as variadic args.
