Although this block has remained in __PMC_EVENTS(), there is no handling of UCP in libpmc/libpmc.c, so it is not possible to select one of these events. It should therefore be impossible to trigger the code removed from ucp_start_pmc(). Note that the GQ_SNOOP_MSF MSR exists only for Nehalem and Westmere architectures, and the related events do not exist for later generations. The Uncore support in hwpmc has severely atrophied in general. We have uncore event definitions in pmu-events, but the kernel support was written against Intel Performance Measurement Architecture version 2, and is disabled for processor generations later than Westmere. Nehalem and Westmere lack uncore event definitions in pmu-events. I'd be surprised if Uncore support is usable on any machine in its current state.
