Pull performance events updates from Ingo Molnar: - Add branch stack counters ABI extension to better capture the growing amount of information the PMU exposes via branch stack sampling. There's matching tooling support. - Fix race when creating the nr_addr_filters sysfs file - Add Intel Sierra Forest and Grand Ridge intel/cstate PMU support - Add Intel Granite Rapids, Sierra Forest and Grand Ridge uncore PMU support - Misc cleanups & fixes * tag 'perf-core-2024-01-08' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: perf/x86/intel/uncore: Factor out topology_gidnid_map() perf/x86/intel/uncore: Fix NULL pointer dereference issue in upi_fill_topology() perf/x86/amd: Reject branch stack for IBS events perf/x86/intel/uncore: Support Sierra Forest and Grand Ridge perf/x86/intel/uncore: Support IIO free-running counters on GNR perf/x86/intel/uncore: Support Granite Rapids perf/x86/uncore: Use u64 to replace unsigned for the uncore offsets array perf/x86/intel/uncore: Generic uncore_get_uncores and MMIO format of SPR perf: Fix the nr_addr_filters fix perf/x86/intel/cstate: Add Grand Ridge support perf/x86/intel/cstate: Add Sierra Forest support x86/smp: Export symbol cpu_clustergroup_mask() perf/x86/intel/cstate: Cleanup duplicate attr_groups perf/core: Fix narrow startup race when creating the perf nr_addr_filters sysfs file perf/x86/intel: Support branch counters logging perf/x86/intel: Reorganize attrs and is_visible perf: Add branch_sample_call_stack perf/x86: Add PERF_X86_EVENT_NEEDS_BRANCH_STACK flag perf: Add branch stack counters
Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
