perf/x86/intel/uncore: Support Granite Rapids
mainline inclusion from mainline-v6.8-rc1 commit 632c4bf6d007862307440b177d9fee829857e8bb category: feature bugzilla: https://gitee.com/openeuler/intel-kernel/issues/I8YW2E CVE: NA Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=632c4bf6d007862307440b177d9fee829857e8bb ------------------------------------- The same as Sapphire Rapids, Granite Rapids also supports the discovery table feature. All the basic uncore PMON information can be retrieved from the discovery table which resides in the BIOS. There are 4 new units are added on Granite Rapids, b2cmi, b2cxl, ubox, and mdf_sbo. The layout of the counters is exactly the same as the generic uncore counters. Only add a name for the new units. All the details can be retrieved from the discovery table. The description of the new units can be found at https://www.intel.com/content/www/us/en/secure/content-details/772943/content-details.html The other units, e.g., cha, iio, irp, pcu, and imc, are the same as Sapphire Rapids. Ignore the upi and b2upi units in the discovery table, which are broken for now.
