The kernel distinguishes local from global IDs by looking at the lowest 6 bits of the thread ID (i.e., in 'L4_ThreadControl'). If those bits are zero, the ID is interpreted as a local ID. Because those zero bits overlap with the version bits of global IDs, this invariant could be violated once the version of a global ID reaches 64. In this case, 'L4_ThreadControl' will return an error on the attempt to create a new PD. To prevent this from happening, we always set the lowest bit to 1. |
