perf/x86/intel/uncore: Add IMC uncore support for ADL
mainline inclusion from mainline-v5.17-rc2 commit 5a4487f9 category: feature feature: SRF core PMU support bugzilla: https://gitee.com/openeuler/intel-kernel/issues/I8RWG5 CVE: NA Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=5a4487f9ef5ef2fdb3215cadf0a9c3e5e8678634 Intel-SIG: commit 5a4487f9 perf/x86/intel/uncore: Add IMC uncore support for ADL Backport as a dependency for Sierra Forrest core PMU support. ------------------------------------- Current ADL uncore code only supports the legacy IMC (memory controller) free-running counters. Besides the free-running counters, ADL also supports several general purpose-counters. The general-purpose counters can also be accessed via MMIO but in a different location. Factor out __uncore_imc_init_box() with offset as a parameter. The function can be shared between ADL and TGL. The event format and the layout of the control registers are a little bit different from other uncore counters. The intel_generic_uncore_mmio_enable_event() can be shared with client IMC uncore. Expose the function. Add more PCI IDs for ADL machines. Fixes: 772ed05f ("perf/x86/intel/uncore: Add Alder Lake support") Signed-off-by:Kan Liang <kan.liang@linux.intel.com> Signed-off-by:
