Cross Domain Limit Log (CROSS_​DOMAIN_​LIMIT_​LOG)

R/WC0 - If set (1), indicates another hardware domain (e.g. processor graphics) has limited energy efficiency optimizations in the processor core domain since the last clearing of this bit or a reset. This bit is sticky, software may clear this bit by writing a zero (0).
