Virtual Common Binary Point Register. The possible values are:
0x0 ICV_BPR0_EL1 determines the preemption group for virtual Group 0 interrupts
only.
ICV_BPR1_EL1 determines the preemption group for virtual Group 1 interrupts.
0x1 ICV_BPR0_EL1 determines the preemption group for both virtual Group 0 and
virtual Group 1 interrupts.
Reads of ICV_BPR1_EL1 return ICV_BPR0_EL1 plus one, saturated to 111. Writes
to ICV_BPR1_EL1 are IGNORED.
VFIQEn, [3]
Virtual FIQ enable. The value is:
0x1 Group 0 virtual interrupts are presented as virtual FIQs.
RES0, [2]
Reserved, RES0.
VENG1, [1]
