Kim Phillips e48667b865 perf/amd/uncore: Add support for Family 19h L3 PMU ... Family 19h introduces change in slice, core and thread specification in its L3 Performance Event Select (ChL3PmcCfg) h/w register. The change is incompatible with Family 17h's version of the register. Introduce a new path in l3_thread_slice_mask() to do things differently for Family 19h vs. Family 17h, otherwise the new hardware doesn't get programmed correctly. Instead of a linear core--thread bitmask, Family 19h takes an encoded core number, and a separate thread mask. There are new bits that are set for all cores and all slices, of which only the latter is used, since the driver counts events for all slices on behalf of the specified CPU. Also update amd_uncore_init() to base its L2/NB vs. L3/Data Fabric mode decision based on Family 17h or above, not just 17h and 18h: the Family 19h Data Fabric PMC is compatible with the Family 17h DF PMC.
