## Detailed Description

Structure that defines some fields of the GEN State Register (SR) and provides access to these fields.

Note:
  Some of these fields could be present in a subset of GEN models, but absent in the rest of models. If a field is not present in a concrete GEN model, it is represented by an empty BitField.
  Instance of this class for a specific GEN model can be obtained by the IGtGenModel::StateRegAccessor() function.

Terminology: The combination of {SliceID, Dual-SubSliceID, SubSliceID, EUID, ThreadSlot} fields is called Global HW Thread Identifier (GTID). The term 'Global' in this context means that the identifier is unique across all slices, subslices, EUs of the entire system.

## Member Function Documentation

uint32_t gtpin::GtStateRegAccessor::SetGlobalTid | ( | uint32_t | sr00,
|  | uint32_t | gtid
| ) |  | const`[inline]`

Set 'gtid' value in the GlobalTid field of sr00.

Returns:
  modified sr00
