      perf tests parse-events: Use "branches" rather than "cache-references" · 78fae207
      Ian Rogers authored
      Switch from "cache-references" to "branches" in test as Intel has a
      sysfs event for "cache-references" and changing the priority for sysfs
      over legacy causes the test to fail.

      perf pmu: Refactor perf_pmu__match() · f91fa2ae
      Ian Rogers authored
      Move all implementation to pmu code. Don't allocate a fnmatch wildcard
      pattern, matching ignoring the suffix already handles this, and only
      use fnmatch if the given PMU name has a '*' in it.

      perf parse-events: Directly pass PMU to parse_events_add_pmu() · 63dfcde9
      Ian Rogers authored
      Avoid passing the name of a PMU then finding it again, just directly
      pass the PMU. parse_events_multi_pmu_add_or_add_pmu() is the only version
      that needs to find a PMU, so move the find there. Remove the error
      message as parse_events_multi_pmu_add_or_add_pmu will given an error at
      the end when a name isn't either a PMU name or event name. Without the
      error message being created the location in the input parameter (loc)
      can be removed.

      perf parse-events: Factor out '<event_or_pmu>/.../' parsing · 8b734eaa
      Ian Rogers authored
      Factor out the case of an event or PMU name followed by a slash based
      term list. This is with a view to sharing the code with new legacy
      hardware parsing. Use early return to reduce indentation in the code.
      Make parse_events_add_pmu static now it doesn't need sharing with
      parse-events.y.

      perf scripts python: Add a script to run instances of 'perf script' in parallel · e0c48bf9
      Adrian Hunter authored
      Add a Python script to run a perf script command multiple times in
      parallel, using perf script options --cpu and --time so that each job
      processes a different chunk of the data.
      
      Extend perf script tests to test also the new script.
      
      The script supports the use of normal 'perf script' options like
      --dlfilter and --script, so that the benefit of running parallel jobs
      naturally extends to them also. In addition, a command can be provided
      (refer --pipe-to option) to pipe standard output to a custom command.
      
      Refer to the script's own help text at the end of the patch for more
      details.
      
      The script is useful for Intel PT traces, that can be efficiently
      decoded by 'perf script' when split by CPU and/or time ranges. Running
      jobs in parallel can decrease the overall decoding time.

      tools lib rbtree: Pick some improvements from the kernel rbtree code · cd88c11c
      Arnaldo Carvalho de Melo authored
      The tools/lib/rbtree.c code came from the kernel, removing the
      EXPORT_SYMBOL() that make sense only there, unfortunately it is not
      being checked with tools/perf/check_headers.sh, will try to remedy this,
      till then pick the improvements from:
      
        b0687c11 ("lib/rbtree: use '+' instead of '|' for setting color.")
      
      That I noticed by doing:
      
        diff -u tools/lib/rbtree.c lib/rbtree.c
        diff -u tools/include/linux/rbtree_augmented.h include/linux/rbtree_augmented.h
      
      There is one other cases, but lets pick it in separate patches.

      This addresses this perf tools build warning:
      
        diff -u tools/perf/trace/beauty/include/uapi/linux/vhost.h include/uapi/linux/vhost.h
      
      But this specific process, usually boring, this time around catch a
      problem, namely the addition of VDPA_GET_VRING_SIZE used an ioctl number
      already taken, which went on unnoticed and only got caught when the
      tools/perf/trace/beauty/vhost_virtio_ioctl.sh script was run as part of
      the perf tools process of updating the tools copies of system headers it
      uses for creating id->string tables that, well, broke the perf tools
      build because there were multiple initializations in the strings table
      for the 0x80 entry...
      
      I'm adding here a link to the discussion, that is lacking in the fix for
      the reported problem, and a quote from one of the developers involved:
      
      "Thanks a lot for taking care of this! So given the header is actually
      buggy pls hang on to this change until I merge the fix for the header
      (you were CC'd on the patch).  It's great we have this redundancy which
      allowed us to catch the bug in time, and many thanks to Namhyung Kim for
      reporting the issue!"
      
      This is here as a hint for anyone thinking about ways to automate
      checking these issues in a more automated way... ;-)

           return thunk in use. This should not happen!" when running KVM
           selftests.
      
        Everything else is small bugfixes and selftest changes:
      
         - Fix a mostly benign bug in the gfn_to_pfn_cache infrastructure
           where KVM would allow userspace to refresh the cache with a bogus
           GPA. The bug has existed for quite some time, but was exposed by a
           new sanity check added in 6.9 (to ensure a cache is either
           GPA-based or HVA-based).
      
         - Drop an unused param from gfn_to_pfn_cache_invalidate_start() that
           got left behind during a 6.9 cleanup.
      
         - Fix a math goof in x86's hugepage logic for
           KVM_SET_MEMORY_ATTRIBUTES that results in an array overflow
           (detected by KASAN).
      
         - Fix a bug where KVM incorrectly clears root_role.direct when
           userspace sets guest CPUID.
      
         - Fix a dirty logging bug in the where KVM fails to write-protect
           SPTEs used by a nested guest, if KVM is using Page-Modification
           Logging and the nested hypervisor is NOT using EPT.
      
        x86 PMU:
      
         - Drop support for virtualizing adaptive PEBS, as KVM's
           implementation is architecturally broken without an obvious/easy
           path forward, and because exposing adaptive PEBS can leak host LBRs
           to the guest, i.e. can leak host kernel addresses to the guest.
      
         - Set the enable bits for general purpose counters in
           PERF_GLOBAL_CTRL at RESET time, as done by both Intel and AMD
           processors.
      
         - Disable LBR virtualization on CPUs that don't support LBR
           callstacks, as KVM unconditionally uses
           PERF_SAMPLE_BRANCH_CALL_STACK when creating the perf event, and
           would fail on such CPUs.
      
        Tests:
      
         - Fix a flaw in the max_guest_memory selftest that results in it
           exhausting the supply of ucall structures when run with more than
           256 vCPUs.
      
         - Mark KVM_MEM_READONLY as supported for RISC-V in
           set_memory_region_test"

      Pull clk fixes from Stephen Boyd:
       "A couple clk driver fixes, a build fix, and a deadlock fix:
      
         - Mediatek mt7988 has broken PCIe because the wrong parent is used
      
         - Mediatek clk drivers may deadlock when registering their clks
           because the clk provider device is repeatedly runtime PM resumed
           and suspended during probe and clk registration.
      
           Resuming the clk provider device deadlocks with an ABBA deadlock
           due to genpd_lock and the clk prepare_lock. The fix is to keep the
           device runtime resumed while registering clks.
      
         - Another runtime PM related deadlock, this time with disabling
           unused clks during late init.
      
           We get an ABBA deadlock where a device is runtime PM resuming (or
           suspending) while the disabling of unused clks is happening in
           parallel. That runtime PM action calls into the clk framework and
           tries to grab the clk prepare_lock while the disabling of unused
           clks holds the prepare_lock and is waiting for that runtime PM
           action to complete.
      
           The fix is to runtime resume all the clk provider devices before
           grabbing the clk prepare_lock during disable unused.
      
         - A build fix to provide an empty devm_clk_rate_exclusive_get()

      On arm64 machines, swsusp_save() faults if it attempts to access
      MEMBLOCK_NOMAP memory ranges. This can be reproduced in QEMU using UEFI
      when booting with rodata=off debug_pagealloc=off and CONFIG_KFENCE=n:

      The reason is swsusp_save() -> copy_data_pages() -> page_is_saveable()
      -> kernel_page_present() assuming that a page is always present when
      can_set_direct_map() is false (all of rodata_full,
      debug_pagealloc_enabled() and arm64_kfence_can_set_direct_map() false),
      irrespective of the MEMBLOCK_NOMAP ranges. Such MEMBLOCK_NOMAP regions
      should not be saved during hibernation.
      
      This problem was introduced by changes to the pfn_valid() logic in
      commit a7d9f306 ("arm64: drop pfn_valid_within() and simplify
      pfn_valid()").
      
      Similar to other architectures, drop the !can_set_direct_map() check in
      kernel_page_present() so that page_is_savable() skips such pages.
      
      Fixes: a7d9f306 ("arm64: drop pfn_valid_within() and simplify pfn_valid()")

      blk-iocost: do not WARN if iocg was already offlined · 01bc4fda
      Li Nan authored
      In iocg_pay_debt(), warn is triggered if 'active_list' is empty, which
      is intended to confirm iocg is active when it has debt. However, warn
      can be triggered during a blkcg or disk removal, if iocg_waitq_timer_fn()
      is run at that time:
      
        WARNING: CPU: 0 PID: 2344971 at block/blk-iocost.c:1402 iocg_pay_debt+0x14c/0x190
        Call trace:
        iocg_pay_debt+0x14c/0x190
        iocg_kick_waitq+0x438/0x4c0
        iocg_waitq_timer_fn+0xd8/0x130
        __run_hrtimer+0x144/0x45c
        __hrtimer_run_queues+0x16c/0x244
        hrtimer_interrupt+0x2cc/0x7b0
      
      The warn in this situation is meaningless. Since this iocg is being
      removed, the state of the 'active_list' is irrelevant, and 'waitq_timer'
      is canceled after removing 'active_list' in ioc_pd_free(), which ensures
      iocg is freed after iocg_waitq_timer_fn() returns.
      
      Therefore, add the check if iocg was already offlined to avoid warn
      when removing a blkcg or disk.
