- * Per-uba structure.
- *
- * This structure holds the interrupt vector for the uba,
- * and its address in physical and virtual space. At boot time
- * we determine the devices attached to the uba's and their
- * interrupt vectors, filling in uh_vec. We free the map
- * register and bdp resources of the uba into the structures
- * defined here.
- *
- * During normal operation, resources are allocated and returned
- * to the structures here. We watch the number of passive releases
- * on each uba, and if the number is excessive may reset the uba.
- *
- * When uba resources are needed and not available, or if a device
- * which can tolerate no other uba activity (rk07) gets on the bus,
- * then device drivers may have to wait to get to the bus and are
- * queued here. It is also possible for processes to block in
- * the unibus driver in resource wait (mrwant, bdpwant); these
- * wait states are also recorded here.
