104 * The devclass object has two main functions in the system. The first
105 * is to manage the allocation of unit numbers for device instances
106 * and the second is to hold the list of device drivers for a
107 * particular bus type. Each devclass has a name and there cannot be
108 * two devclasses with the same name. This ensures that unique unit
109 * numbers are allocated to device instances.
111 * Drivers that support several different bus attachments (e.g. isa,
112 * pci, pccard) should all use the same devclass to ensure that unit
113 * numbers do not conflict.
115 * Each devclass may also have a parent devclass. This is used when
116 * searching for device drivers to allow a form of inheritance. When
117 * matching drivers with devices, first the driver list of the parent
118 * device's devclass is searched. If no driver is found in that list,
119 * the search continues in the parent devclass (if any).

137 * FILTER_HANDLED - the interrupt has been fully handled and can be EOId

141 * If the driver does not provide a filter, then the interrupt code will
142 * act is if the filter had returned FILTER_SCHEDULE_THREAD. Note that it
143 * is illegal to specify any other flag with FILTER_STRAY and that it is
144 * illegal to not specify either of FILTER_HANDLED or FILTER_SCHEDULE_THREAD

154 * The filter routine is run in primary interrupt context and may not
155 * block or use regular mutexes. It may only use spin mutexes for
156 * synchronization. The filter may either completely handle the
157 * interrupt or it may perform some of the work and defer more
158 * expensive work to the regular interrupt handler. If a filter
159 * routine is not registered by the driver, then the regular interrupt
160 * handler is always used to handle interrupts from this device.
162 * The regular interrupt handler executes in its own thread context
163 * and may use regular mutexes. However, it is prohibited from
164 * sleeping on a sleep queue.
