Merge tag 'perf-core-2020-10-12' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull performance events updates from Ingo Molnar: "x86 Intel updates: - Add Jasper Lake support - Add support for TopDown metrics on Ice Lake - Fix Ice Lake & Tiger Lake uncore support, add Snow Ridge support - Add a PCI sub driver to support uncore PMUs where the PCI resources have been claimed already - extending the range of supported systems. x86 AMD updates: - Restore 'perf stat -a' behaviour to program the uncore PMU to count all CPU threads. - Fix setting the proper count when sampling Large Increment per Cycle events / 'paired' events. - Fix IBS Fetch sampling on F17h and some other IBS fine tuning, greatly reducing the number of interrupts when large sample periods are specified. - Extends Family 17h RAPL support to also work on compatible F19h machines. Core code updates: - Fix race in perf_mmap_close() - Add PERF_EV_CAP_SIBLING, to denote that sibling events should be closed if the leader is removed. - Smaller fixes and updates" * tag 'perf-core-2020-10-12' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: (45 commits) perf/core: Fix race in the perf_mmap_close() function perf/x86: Fix n_metric for cancelled txn perf/x86: Fix n_pair for cancelled txn x86/events/amd/iommu: Fix sizeof mismatch perf/x86/intel: Check perf metrics feature for each CPU perf/x86/intel: Fix Ice Lake event constraint table perf/x86/intel/uncore: Fix the scale of the IMC free-running events perf/x86/intel/uncore: Fix for iio mapping on Skylake Server perf/x86/msr: Add Jasper Lake support perf/x86/intel: Add Jasper Lake support perf/x86/intel/uncore: Reduce the number of CBOX counters perf/x86/intel/uncore: Update Ice Lake uncore units perf/x86/intel/uncore: Split the Ice Lake and Tiger Lake MSR uncore support perf/x86/intel/uncore: Support PCIe3 unit on Snow Ridge perf/x86/intel/uncore: Generic support for the PCI sub driver perf/x86/intel/uncore: Factor out uncore_pci_pmu_unregister() perf/x86/intel/uncore: Factor out uncore_pci_pmu_register() perf/x86/intel/uncore: Factor out uncore_pci_find_dev_pmu() perf/x86/intel/uncore: Factor out uncore_pci_get_dev_die_info() perf/amd/uncore: Inform the user how many counters each uncore PMU has ...
