MCHBAR Registers
7.72 GT—Offset 5900h
Interface to allow software to determine what is causing resolved frequency to be
clamped below the requested frequency. Status bits are updated by hardware through
the io interface IO_GT_PERF_LIMIT, log bits are set by HW on a status bit edge
detected and cleared by a SW write of '0'.
