Reference Counter MSR
A partition's reference counter is accessed through a partition-wide reference counter model-specific register (MSR). The reference counter MSR is shown in the following table.
| MSR address | Register name | Function |
|---|---|---|
|
0x40000020 |
HV_X64_MSR_TIME_REF_COUNT |
Time reference count (partition-wide) |
When a partition is created, the value of the TIME_REF_COUNT MSR is set to 0x0000000000000000. This value cannot be modified by a virtual processor. Any attempt to write to it results in a #GP fault.
