The GITS_TRKTGTR characteristics are:

Purpose

This register returns the target core of the LPI that is tracked as a result of the LPI track bit in the GITS_TRKCTLR register being set to 0b1.

Usage constraints

This register is only valid when the LPI tracked field in GITS_TRKR is 1 and none of the other bits in the register is 1.

Configurations

Present in configurations of the GIC-500 with ITS and LPI support.

Attributes

See the register summary in Table 3.21.
