Merge tag 'perf-tools-for-v6.2-1-2022-12-16' of git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux Pull perf tools updates from Arnaldo Carvalho de Melo: "Libraries: - Drop the old copy of libtraceevent in tools/lib/traceevent/ now that all major distros ship it from its external repository. This is now just another feature detection, emitting a warning when the libtraceevent-dev[el] package isn't installed, disabling the build of perf features and tools that strictly require parsing things from tracefs while keeping the core functionality present and working with a subset of the events, the most used ones like CPU cycles, hardware cache and also vendor events, etc. This was tested with lots of containers for Fedora, Debian, OpenSUSE, Alpine Linux, Ubuntu, with cross builds, etc. Build: - Update to C standard to gnu11, like was done for the kernel. - Install the tools/lib/ libraries locally instead of having headers searched directly from the source code directories, to help the cases where we can build either from in-kernel source libraries or from the same library shipped as a distro package, as is the case with libbpf and was the case with libtraceevent. perf stat: - Do not delay the workload with --delay, the delay is just for starting to count the events, to skip noise at workload startup. - When we have events for each cgroup, the metric should be printed for each cgroup separately. $ perf stat -a --for-each-cgroup system.slice,user.slice --metric-only sleep 1 Performance counter stats for 'system wide': GHz insn per cycle branch-misses of all branches system.slice 3.792 0.61 3.24% user.slice 3.661 2.32 0.37% - Fix printing field separator in CSV metrics output. - Fix --metric-only --json output. - Fix summary output in CSV with --metric-only. - Update event group check for support of uncore event. perf test: - Stop requiring a C toolchain in shell tests, instead add a workload option that has all the previously C snippets built as part of 'perf test -w' that then get used in the 'perf test' shell scripts. - Add event group test for events in multiple PMUs - The "kernel lock contention analysis" test should not print warnings in quiet mode. - Add attr tests for ARM64's new VG register. - Fix record test on KVM guests, as using precise flag with the br_inst_retired.near_call event causes the test fail on KVM guests, even when the guests have PMU forwarding enabled and the event itself is supported, so just remove the precise flag from the event. - Add mechanism for skipping attr tests on specific kernel versions where it is known that these checks will fail. - Skip watchpoint tests if no watchpoints available. - Add more Intel PT 'perf test' entries: hybrid CPUs, split the packet decoder into a suite of subtests. perf script: - Introduce task analyzer python script, where one first records some events: Recording can be done in two ways: $ perf script record tasks-analyzer -- sleep 10 $ perf record -e sched:sched_switch -a -- sleep 10 The script can parse any perf.data files, as long as it has sched:sched_switch events, other events will be ignored. The most simple report use case is to just call the script without arguments. Runtime is the time the task was running on the CPU, Time Out-In is the time between the process being scheduled *out* and scheduled back *in*. So the last time span between two executions: $ perf script report tasks-analyzer Switched-In Switched-Out CPU PID TID Comm Runtime Time Out-In 15576.658891407 15576.659156086 4 2412 2428 gdbus 265 1949 15576.659111320 15576.659455410 0 2412 2412 gnome-shell 344 2267 15576.659491326 15576.659506173 2 74 74 kworker/2:1 15 13145 15576.659506173 15576.659825748 2 2858 2858 gnome-terminal- 320 63263 15576.659871270 15576.659902872 6 20932 20932 kworker/u16:0 32 2314582 15576.659909951 15576.659945501 3 27264 27264 sh 36 -1 15576.659853285 15576.659971052 7 27265 27265 perf 118 5050741 [...] perf lock: - Allow concurrent record and report to support live monitoring of kernel lock contention without BPF: # perf lock record -a -o- sleep 1 | perf lock contention -i- contended total wait max wait avg wait type caller 2 10.27 us 6.17 us 5.13 us spinlock load_balance+0xc03 1 5.29 us 5.29 us 5.29 us rwlock:W ep_scan_ready_list+0x54 1 4.12 us 4.12 us 4.12 us spinlock smpboot_thread_fn+0x116 1 3.28 us 3.28 us 3.28 us mutex pipe_read+0x50 - Implement -t/--threads option when using BPF: $ sudo ./perf lock contention -abt -E 5 sleep 1 contended total wait max wait avg wait pid comm 1 740.66 ms 740.66 ms 740.66 ms 1950 nv_queue 3 305.50 ms 298.19 ms 101.83 ms 1884 nvidia-modeset/ 1 25.14 us 25.14 us 25.14 us 2725038 EventManager_De 12 23.09 us 9.30 us 1.92 us 0 swapper 1 20.18 us 20.18 us 20.18 us 2725033 EventManager_De - Add -l/--lock-addr to aggregate per-lock-instance contention: $ sudo ./perf lock contention -abl sleep 1 contended total wait max wait avg wait address symbol 1 36.28 us 36.28 us 36.28 us ffff92615d6448b8 9 10.91 us 1.84 us 1.21 us ffffffffbaed50c0 rcu_state 1 10.49 us 10.49 us 10.49 us ffff9262ac4f0c80 8 4.68 us 1.67 us 585 ns ffffffffbae07a40 jiffies_lock 3 3.03 us 1.45 us 1.01 us ffff9262277861e0 1 924 ns 924 ns 924 ns ffff926095ba9d20 1 436 ns 436 ns 436 ns ffff9260bfda4f60 perf record: - Add remaining branch filters: "no_cycles", "no_flags" & "hw_index", to be used with hardware such as Intel's LBR that allows things like stitching stacks of two samples to overcome the limits of the number of LBR registers. Symbol resolution: - Handle .debug files created with 'objcopy --only-keep-debug', where program headers are zeroed and thus can't be used for adjustments, use the info in the runtime_ss (runtime ELF) instead. perf trace: - Add BPF based augmenter for the 'perf_event_open's 'struct perf_event_attr' argument. - Add BPF based augmenter for the 'clock_gettime's 'struct timespec' argument. - In both cases the syscall tracepoint has just the pointer value, we need to hook a BPF program to collect the pointer contents, and then, in userspace, pretty print it in 'perf trace'. perf list: - Introduce JSON output of events. - Streamline how the expression specifying what events should be shown is handled, fixing several corner cases, such as the metric filter that is specified as a glob but was using strstr(). perf probe: - Fix to avoid crashing if DW_AT_decl_file is NULL, coping with clang generating DWARF5 like that. - Use dwarf_attr_integrate() as generic DWARF attr accessor as it supersedes dwarf_attr(), supporting abstact origin DIEs. perf inject: - Set PERF_RECORD_MISC_BUILD_ID_SIZE in the PERF_RECORD_HEADER_BUILD_ID so that perf.data readers can get the real build-id size and avoid trailing zeroes. perf data: - Add tracepoint fields when converting a perf.data file to JSON. arm64: - Fix mksyscalltbl, don't lose syscalls due to sort -nu. - Add Arm Neoverse V2 PMU events. riscv: - Add riscv sbi firmware std event files. - Add Sifive U74 vendor events (JSON) file. - Add some more events and metrics for Alderlake/Alderlake-N.

This was a mismerge of a semantic conflict in my merge of the driver core updates, where commit ff62b8e6 ("driver core: make struct class.devnode() take a const *") changed the devnode function pointer type. In the meantime, the drm tree I merged earlier had introduced a new use of that in commit 8bf48897 ("drivers/accel: define kconfig and register a new major"). And of course this happens when I'm traveling with my laptop, and thus didn't do a full allmodconfig build between every pull and before pushing my work out. So I only noticed later as I was doing my full build.

Pull driver core updates from Greg KH: "Here is the set of driver core and kernfs changes for 6.2-rc1. The "big" change in here is the addition of a new macro, container_of_const() that will preserve the "const-ness" of a pointer passed into it. The "problem" of the current container_of() macro is that if you pass in a "const *", out of it can comes a non-const pointer unless you specifically ask for it. For many usages, we want to preserve the "const" attribute by using the same call. For a specific example, this series changes the kobj_to_dev() macro to use it, allowing it to be used no matter what the const value is. This prevents every subsystem from having to declare 2 different individual macros (i.e. kobj_const_to_dev() and kobj_to_dev()) and having the compiler enforce the const value at build time, which having 2 macros would not do either. The driver for all of this have been discussions with the Rust kernel developers as to how to properly mark driver core, and kobject, objects as being "non-mutable". The changes to the kobject and driver core in this pull request are the result of that, as there are lots of paths where kobjects and device pointers are not modified at all, so marking them as "const" allows the compiler to enforce this. So, a nice side affect of the Rust development effort has been already to clean up the driver core code to be more obvious about object rules. All of this has been bike-shedded in quite a lot of detail on lkml with different names and implementations resulting in the tiny version we have in here, much better than my original proposal. Lots of subsystem maintainers have acked the changes as well. Other than this change, included in here are smaller stuff like: - kernfs fixes and updates to handle lock contention better - vmlinux.lds.h fixes and updates - sysfs and debugfs documentation updates - device property updates All of these have been in the linux-next tree for quite a while with no problems" * tag 'driver-core-6.2-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core: (58 commits) device property: Fix documentation for fwnode_get_next_parent() firmware_loader: fix up to_fw_sysfs() to preserve const usb.h: take advantage of container_of_const() device.h: move kobj_to_dev() to use container_of_const() container_of: add container_of_const() that preserves const-ness of the pointer driver core: fix up missed drivers/s390/char/hmcdrv_dev.c class.devnode() conversion. driver core: fix up missed scsi/cxlflash class.devnode() conversion. driver core: fix up some missing class.devnode() conversions. driver core: make struct class.devnode() take a const * driver core: make struct class.dev_uevent() take a const * cacheinfo: Remove of_node_put() for fw_token device property: Add a blank line in Kconfig of tests device property: Rename goto label to be more precise device property: Move PROPERTY_ENTRY_BOOL() a bit down device property: Get rid of __PROPERTY_ENTRY_ARRAY_EL*SIZE*() kernfs: fix all kernel-doc warnings and multiple typos driver core: pass a const * into of_device_uevent() kobject: kset_uevent_ops: make name() callback take a const * kobject: kset_uevent_ops: make filter() callback take a const * kobject: make kobject_namespace take a const * ...

Pull kvm updates from Paolo Bonzini: "ARM64: - Enable the per-vcpu dirty-ring tracking mechanism, together with an option to keep the good old dirty log around for pages that are dirtied by something other than a vcpu. - Switch to the relaxed parallel fault handling, using RCU to delay page table reclaim and giving better performance under load. - Relax the MTE ABI, allowing a VMM to use the MAP_SHARED mapping option, which multi-process VMMs such as crosvm rely on (see merge commit 382b5b87: "Fix a number of issues with MTE, such as races on the tags being initialised vs the PG_mte_tagged flag as well as the lack of support for VM_SHARED when KVM is involved. Patches from Catalin Marinas and Peter Collingbourne"). - Merge the pKVM shadow vcpu state tracking that allows the hypervisor to have its own view of a vcpu, keeping that state private. - Add support for the PMUv3p5 architecture revision, bringing support for 64bit counters on systems that support it, and fix the no-quite-compliant CHAIN-ed counter support for the machines that actually exist out there. - Fix a handful of minor issues around 52bit VA/PA support (64kB pages only) as a prefix of the oncoming support for 4kB and 16kB pages. - Pick a small set of documentation and spelling fixes, because no good merge window would be complete without those. s390: - Second batch of the lazy destroy patches - First batch of KVM changes for kernel virtual != physical address support - Removal of a unused function x86: - Allow compiling out SMM support - Cleanup and documentation of SMM state save area format - Preserve interrupt shadow in SMM state save area - Respond to generic signals during slow page faults - Fixes and optimizations for the non-executable huge page errata fix. - Reprogram all performance counters on PMU filter change - Cleanups to Hyper-V emulation and tests - Process Hyper-V TLB flushes from a nested guest (i.e. from a L2 guest running on top of a L1 Hyper-V hypervisor) - Advertise several new Intel features - x86 Xen-for-KVM: - Allow the Xen runstate information to cross a page boundary - Allow XEN_RUNSTATE_UPDATE flag behaviour to be configured - Add support for 32-bit guests in SCHEDOP_poll - Notable x86 fixes and cleanups: - One-off fixes for various emulation flows (SGX, VMXON, NRIPS=0). - Reinstate IBPB on emulated VM-Exit that was incorrectly dropped a few years back when eliminating unnecessary barriers when switching between vmcs01 and vmcs02. - Clean up vmread_error_trampoline() to make it more obvious that params must be passed on the stack, even for x86-64. - Let userspace set all supported bits in MSR_IA32_FEAT_CTL irrespective of the current guest CPUID. - Fudge around a race with TSC refinement that results in KVM incorrectly thinking a guest needs TSC scaling when running on a CPU with a constant TSC, but no hardware-enumerated TSC frequency. - Advertise (on AMD) that the SMM_CTL MSR is not supported - Remove unnecessary exports Generic: - Support for responding to signals during page faults; introduces new FOLL_INTERRUPTIBLE flag that was reviewed by mm folks Selftests: - Fix an inverted check in the access tracking perf test, and restore support for asserting that there aren't too many idle pages when running on bare metal. - Fix build errors that occur in certain setups (unsure exactly what is unique about the problematic setup) due to glibc overriding static_assert() to a variant that requires a custom message. - Introduce actual atomics for clear/set_bit() in selftests - Add support for pinning vCPUs in dirty_log_perf_test. - Rename the so called "perf_util" framework to "memstress". - Add a lightweight psuedo RNG for guest use, and use it to randomize the access pattern and write vs. read percentage in the memstress tests. - Add a common ucall implementation; code dedup and pre-work for running SEV (and beyond) guests in selftests. - Provide a common constructor and arch hook, which will eventually be used by x86 to automatically select the right hypercall (AMD vs. Intel). - A bunch of added/enabled/fixed selftests for ARM64, covering memslots, breakpoints, stage-2 faults and access tracking. - x86-specific selftest changes: - Clean up x86's page table management. - Clean up and enhance the "smaller maxphyaddr" test, and add a related test to cover generic emulation failure. - Clean up the nEPT support checks. - Add X86_PROPERTY_* framework to retrieve multi-bit CPUID values. - Fix an ordering issue in the AMX test introduced by recent conversions to use kvm_cpu_has(), and harden the code to guard against similar bugs in the future. Anything that tiggers caching of KVM's supported CPUID, kvm_cpu_has() in this case, effectively hides opt-in XSAVE features if the caching occurs before the test opts in via prctl().

This reverts commit 44ecda71. All versions of this patch on the mailing list, including the version that ended up getting merged, have portions of code guarded by the non-existent CONFIG_ARM64_WORKAROUND_2645198 option. Although Anshuman says he tested the code with some additional debug changes [1], I'm hesitant to fix the CONFIG option and light up a bunch of code right before I (and others) disappear for the end of year holidays, during which time we won't be around to deal with any fallout. So revert the change for now. We can bring back a fixed, tested version for a later -rc when folks are thinking about things other than trees and turkeys.

Pull f2fs updates from Jaegeuk Kim: "In this round, we've added two features: F2FS_IOC_START_ATOMIC_REPLACE and a per-block age-based extent cache. F2FS_IOC_START_ATOMIC_REPLACE is a variant of the previous atomic write feature which guarantees a per-file atomicity. It would be more efficient than AtomicFile implementation in Android framework. The per-block age-based extent cache implements another type of extent cache in memory which keeps the per-block age in a file, so that block allocator could split the hot and cold data blocks more accurately. Enhancements: - introduce F2FS_IOC_START_ATOMIC_REPLACE - refactor extent_cache to add a new per-block-age-based extent cache support - introduce discard_urgent_util, gc_mode, max_ordered_discard sysfs knobs - add proc entry to show discard_plist info - optimize iteration over sparse directories - add barrier mount option Bug fixes: - avoid victim selection from previous victim section - fix to enable compress for newly created file if extension matches - set zstd compress level correctly - initialize locks early in f2fs_fill_super() to fix bugs reported by syzbot - correct i_size change for atomic writes - allow to read node block after shutdown - allow to set compression for inlined file - fix gc mode when gc_urgent_high_remaining is 1 - should put a page when checking the summary info Minor fixes and various clean-ups in GC, discard, debugfs, sysfs, and doc" * tag 'f2fs-for-6.2-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/jaegeuk/f2fs: (63 commits) f2fs: reset wait_ms to default if any of the victims have been selected f2fs: fix some format WARNING in debug.c and sysfs.c f2fs: don't call f2fs_issue_discard_timeout() when discard_cmd_cnt is 0 in f2fs_put_super() f2fs: fix iostat parameter for discard f2fs: Fix spelling mistake in label: free_bio_enrty_cache -> free_bio_entry_cache f2fs: add block_age-based extent cache f2fs: allocate the extent_cache by default f2fs: refactor extent_cache to support for read and more f2fs: remove unnecessary __init_extent_tree f2fs: move internal functions into extent_cache.c f2fs: specify extent cache for read explicitly f2fs: introduce f2fs_is_readonly() for readability f2fs: remove F2FS_SET_FEATURE() and F2FS_CLEAR_FEATURE() macro f2fs: do some cleanup for f2fs module init MAINTAINERS: Add f2fs bug tracker link f2fs: remove the unused flush argument to change_curseg f2fs: open code allocate_segment_by_default f2fs: remove struct segment_allocation default_salloc_ops f2fs: introduce discard_urgent_util sysfs node f2fs: define MIN_DISCARD_GRANULARITY macro ...

Pull x86 core updates from Borislav Petkov: - Add the call depth tracking mitigation for Retbleed which has been long in the making. It is a lighterweight software-only fix for Skylake-based cores where enabling IBRS is a big hammer and causes a significant performance impact. What it basically does is, it aligns all kernel functions to 16 bytes boundary and adds a 16-byte padding before the function, objtool collects all functions' locations and when the mitigation gets applied, it patches a call accounting thunk which is used to track the call depth of the stack at any time. When that call depth reaches a magical, microarchitecture-specific value for the Return Stack Buffer, the code stuffs that RSB and avoids its underflow which could otherwise lead to the Intel variant of Retbleed. This software-only solution brings a lot of the lost performance back, as benchmarks suggest: https://lore.kernel.org/all/20220915111039.092790446@infradead.org/ That page above also contains a lot more detailed explanation of the whole mechanism - Implement a new control flow integrity scheme called FineIBT which is based on the software kCFI implementation and uses hardware IBT support where present to annotate and track indirect branches using a hash to validate them - Other misc fixes and cleanups * tag 'x86_core_for_v6.2' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: (80 commits) x86/paravirt: Use common macro for creating simple asm paravirt functions x86/paravirt: Remove clobber bitmask from .parainstructions x86/debug: Include percpu.h in debugreg.h to get DECLARE_PER_CPU() et al x86/cpufeatures: Move X86_FEATURE_CALL_DEPTH from bit 18 to bit 19 of word 11, to leave space for WIP X86_FEATURE_SGX_EDECCSSA bit x86/Kconfig: Enable kernel IBT by default x86,pm: Force out-of-line memcpy() objtool: Fix weak hole vs prefix symbol objtool: Optimize elf_dirty_reloc_sym() x86/cfi: Add boot time hash randomization x86/cfi: Boot time selection of CFI scheme x86/ibt: Implement FineIBT objtool: Add --cfi to generate the .cfi_sites section x86: Add prefix symbols for function padding objtool: Add option to generate prefix symbols objtool: Avoid O(bloody terrible) behaviour -- an ode to libelf objtool: Slice up elf_create_section_symbol() kallsyms: Revert "Take callthunks into account" x86: Unconfuse CONFIG_ and X86_FEATURE_ namespaces x86/retpoline: Fix crash printing warning x86/paravirt: Fix a !PARAVIRT build warning ...
