83 *
84 * to a proper instruction sequence that installs the
85 * universe interrupt manager. This requires knowledge
86 * of the wiring between the universe and the PIC (main
87 * interrupt controller), i.e., which IRQ 'pins' of the
88 * universe are wired to which 'lines'/inputs at the PIC.
89 * (consult vmeUniverse.h for more information).
90 *
91 * When installing the universe IRQ manager it is also
92 * possible to specify whether it should try to share
93 * PIC interrupts with other sources. This might not
94 * be supported by all BSPs (but the unverse driver
95 * recognizes that).
96 *
97 * If BSP_VME_INSTALL_IRQ_MGR is undefined then
98 * the default algorithm is used (vme_universe.c):
99 *
100 * This default setup uses only a single wire. It reads
101 * the PIC 'line' from PCI configuration space and assumes
102 * this to be wired to the first (LIRQ0) IRQ input at the
103 * universe. The default setup tries to use interrupt
104 * sharing.
