+  Attributes:
+    The attr field of kvm_device_attr encodes two values:
+    bits:     | 63   ....  40 | 39 ..  32  |  31   ....    0 |
+    values:   |    reserved   |   cpu id   |      offset     |
+
+    All distributor regs are (rw, 32-bit)

+    reading or writing the register on the actual hardware from the cpu
+    specified with cpu id field.  Note that most distributor fields are not
+    banked, but return the same value regardless of the cpu id used to access
+    the register.
+  Limitations:
+    - Priorities are not implemented, and registers are RAZ/WI

+
+    The Active Priorities Registers APRn are implementation defined, so we set a
+    fixed format for our implementation that fits with the model of a "GICv2
+    implementation without the security extensions" which we present to the
+    guest.  This interface always exposes four register APR[0-3] describing the
+    maximum possible 128 preemption levels.  The semantics of the register
+    indicate if any interrupts in a given preemption level are in the active
+    state by setting the corresponding bit.
+
+    Thus, preemption level X has one or more active interrupts if and only if:
+
+      APRn[X mod 32] == 0b1,  where n = X / 32
+
+    Bits for undefined preemption levels are RAZ/WI.
