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

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

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

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