      perf cs-etm: Print the decoder name · 0a69e897
      James Clark authored
      
      
      Use the real name of the decoder instead of hard-coding "ETM" to avoid
      confusion when the trace is ETE. This also now distinguishes between
      ETMv3 and ETMv4.

      perf cs-etm: Create ETE decoder · 831f307d
      James Clark authored
      
      
      If the TRCDEVARCH register was saved, and it shows that ETE is present,
      then instantiate an OCSD_BUILTIN_DCD_ETE decoder instead of
      OCSD_BUILTIN_DCD_ETMV4I. ETE is the new trace feature for Armv9.
      
      Testing performed
      =================
      
      * Old files with v0 headers still open correctly
      * Old files with v1 headers with no TRCDEVARCH saved still open
      * New files with TRCDEVARCH open using an old version of perf that
        supports v1 headers
      * Coresight decoding results in the same output if there are no new ETE
        packet types

      perf cs-etm: Update OpenCSD decoder for ETE · 709bbed7
      James Clark authored
      
      
      OpenCSD v1.1.1 has a bug fix for the installation of the ETE decoder
      headers. This also means that including headers separately for each
      decoder is unnecessary so remove these.

      perf cs-etm: Save TRCDEVARCH register · 686aea4a
      James Clark authored
      
      
      Now that the metadata has a length field we can add extra registers
      without breaking any previous versions of perf.
      
      Save the TRCDEVARCH register so that it can be used to configure the ETE
      decoder in the next commit. If the sysfs file doesn't exist then 0 will
      be saved which is an impossible register value and can also be used to
      signify that the file couldn't be read.

      perf cs-etm: Pass unformatted flag to decoder · 4da8dc92
      James Clark authored
      The TRBE (Trace Buffer Extension) feature allows a separate trace buffer
      for each trace source, therefore the trace wouldn't need to be
      formatted. The driver was introduced in commit 3fbf7f01
      
      
      ("coresight: sink: Add TRBE driver").
      
      The formatted/unformatted mode is encoded in one of the flags of the
      AUX record. The first AUX record encountered for each event is used to
      determine the mode, and this will persist for the remaining trace that
      is either decoded or dumped.

      When dumping trace, the decoder is continually deleted and recreated to

      perf cs-etm: Suppress printing when resetting decoder · 72d7f0b6
      James Clark authored
      
      
      The decoder is quite noisy when being reset. In a future commit,
      dump-raw-trace will use a code path that resets the decoder rather than
      creating a new one, so printing has to be suppressed to not flood the

      perf cs-etm: Only setup queues when they are modified · cb7a9217
      James Clark authored
      
      
      Continually creating queues in cs_etm__process_event() is unnecessary.
      They only need to be created when a buffer for a new CPU or thread is
      encountered. This can be in two places, when building the queues in
      advance in cs_etm__process_auxtrace_info(), or in
      cs_etm__process_auxtrace_event() when data_queued is false and the
      index wasn't available (pipe mode).
      
      This change will allow the 'formatted' decoder setting to applied when
      iterating over aux records in a later commit.

      perf cs-etm: Split setup and timestamp search functions · eadc9bbe
      James Clark authored
      
      
      This refactoring has some benefits:
       * Decoding is done to find the timestamp. If we want to print errors
         when maps aren't available, then doing it from cs_etm__setup_queue()
         may cause warnings to be printed.
       * The cs_etm__setup_queue() flow is shared between timed and timeless
         modes, so it needs to be guarded by an if statement which can now
         be removed.
       * Allows moving the setup queues function earlier.
       * If data was piped in, then not all queues would be filled so it
         wouldn't have worked properly anyway. Now it waits for flush so
         data in all queues will be available.
      
      The motivation for this is to decouple setup functions with ones that
      involve decoding. That way we can move the setup function earlier when
      the formatted/unformatted trace information is available.

      perf cs-etm: Refactor initialisation of kernel start address · 5a972c40
      James Clark authored
      
      
      The kernel start address is already cached in the machine struct once it
      is initialised, so storing it in the cs_etm struct is unnecessary.
      
      It also depends on kernel maps being available to be initialised.
      Therefore cs_etm__setup_queues() isn't an appropriate place to call it
      because it could be called before processing starts. It would be better
      to initialise it at the point when it is needed, then we can be sure
      that all the necessary maps are available. Also by calling
      machine__kernel_start() multiple times it can be initialised at some
      point, even if it failed to initialise previously due to missing maps.
      
      In a later commit cs_etm__setup_queues() will be moved which is the
      motivation for this change.

      perf cs-etm: Split --dump-raw-trace by AUX records · fd051ab7
      James Clark authored
      
      
      Currently --dump-raw-trace skips queueing and splitting buffers because
      of an early exit condition in cs_etm__process_auxtrace_info(). Once
      that is removed we can print the split data by using the queues
      and searching for split buffers with the same reference as the
      one that is currently being processed.
      
      This keeps the same behaviour of dumping in file order when an AUXTRACE
      event appears, rather than moving trace dump to where AUX records are in
      the file.
      
      There will be a newline and size printout for each fragment. For example
      this buffer is comprised of two AUX records, but was printed as one:
      
        0 0 0x8098 [0x30]: PERF_RECORD_AUXTRACE size: 0xa0  offset: 0  ref: 0x491a4dfc52fc0e6e  idx: 0  t
      
        . ... CoreSight ETM Trace data: size 160 bytes
                Idx:0; ID:10;   I_ASYNC : Alignment Synchronisation.
                Idx:12; ID:10;  I_TRACE_INFO : Trace Info.; INFO=0x0 { CC.0 }
                Idx:17; ID:10;  I_ADDR_L_64IS0 : Address, Long, 64 bit, IS0.; Addr=0x0000000000000000;
                Idx:80; ID:10;  I_ASYNC : Alignment Synchronisation.
                Idx:92; ID:10;  I_TRACE_INFO : Trace Info.; INFO=0x0 { CC.0 }
                Idx:97; ID:10;  I_ADDR_L_64IS0 : Address, Long, 64 bit, IS0.; Addr=0xFFFFDE2AD3FD76D4;
      
      But is now printed as two fragments:
      
        0 0 0x8098 [0x30]: PERF_RECORD_AUXTRACE size: 0xa0  offset: 0  ref: 0x491a4dfc52fc0e6e  idx: 0  t
      
        . ... CoreSight ETM Trace data: size 80 bytes
                Idx:0; ID:10;   I_ASYNC : Alignment Synchronisation.
                Idx:12; ID:10;  I_TRACE_INFO : Trace Info.; INFO=0x0 { CC.0 }
                Idx:17; ID:10;  I_ADDR_L_64IS0 : Address, Long, 64 bit, IS0.; Addr=0x0000000000000000;

      Decoding errors that appeared in problematic files are now not present,
      for example:
      
              Idx:808; ID:1c; I_BAD_SEQUENCE : Invalid Sequence in packet.[I_ASYNC]
              ...

      perf cs-etm: Split Coresight decode by aux records · 0843eb9d
      James Clark authored
      
      
      Populate the auxtrace queues using AUX records rather than whole
      auxtrace buffers so that the decoder is reset between each aux record.
      
      This is similar to the auxtrace_queues__process_index() ->
      auxtrace_queues__add_indexed_event() flow where
      perf_session__peek_event() is used to read AUXTRACE events out of
      random positions in the file based on the auxtrace index. But now we
      loop over all PERF_RECORD_AUX events instead of AUXTRACE buffers. For
      each PERF_RECORD_AUX event, we find the corresponding AUXTRACE buffer
      using the index, and add a fragment of that buffer to the auxtrace
      queues. No other changes to decoding were made, apart from populating
      the auxtrace queues. The result of decoding is identical to before,
      except in cases where decoding failed completely, due to not resetting
      the decoder.
      
      The reason for this change is because AUX records are emitted any time
      tracing is disabled, for example when the process is scheduled out.
      Because ETM was disabled and enabled again, the decoder also needs to
      be reset to force the search for a sync packet. Otherwise there would
      be fatal decoding errors.
      
      Testing
      =======
      
      Testing was done with the following script, to diff the decoding results
      between the patched and un-patched versions of perf:
      
      	#!/bin/bash
      	set -ex
      
      	$1 script -i $3 $4 > split.script
      	$2 script -i $3 $4 > default.script
      
      	diff split.script default.script | head -n 20
      
      And it was run like this, with various itrace options depending on the
      quantity of synthesised events:
      
      	compare.sh ./perf-patched ./perf-default perf-per-cpu-2-threads.data --itrace=i100000ns
      
      No changes in output were observed in the following scenarios:
      
      * Simple per-cpu
      	perf record -e cs_etm/@tmc_etr0/u top
      
      * Per-thread, single thread
      	perf record -e cs_etm/@tmc_etr0/u --per-thread ./threads_C
      
      * Per-thread multiple threads (but only one thread collected data):
      	perf record -e cs_etm/@tmc_etr0/u --per-thread --pid 4596,4597
      
      * Per-thread multiple threads (both threads collected data):
      	perf record -e cs_etm/@tmc_etr0/u --per-thread --pid 4596,4597
      
      * Per-cpu explicit threads:
      	perf record -e cs_etm/@tmc_etr0/u --pid 853,854
      
      * System-wide (per-cpu):
          perf record -e cs_etm/@tmc_etr0/u -a
      
      * No data collected (no aux buffers)
      	Can happen with any command when run for a short period
      
      * Containing truncated records
      	Can happen with any command
      
      * Containing aux records with 0 size
      	Can happen with any command
      
      * Snapshot mode (various files with and without buffer wrap)
      	perf record -e cs_etm/@tmc_etr0/u -a --snapshot
      
      Some differences were observed in the following scenario:
      
      * Snapshot mode (with duplicate buffers)
      	perf record -e cs_etm/@tmc_etr0/u -a --snapshot
      
      Fewer samples are generated in snapshot mode if duplicate buffers
      were gathered because buffers with the same offset are now only added
      once. This gives different, but more correct results and no duplicate
      data is decoded any more.

      mm/rmap: fix old bug: munlocking THP missed other mlocks · d9770fcc
      Hugh Dickins authored
      The kernel recovers in due course from missing Mlocked pages: but there
      was no point in calling page_mlock() (formerly known as
      try_to_munlock()) on a THP, because nothing got done even when it was
      found to be mapped in another VM_LOCKED vma.
      
      It's true that we need to be careful: Mlocked accounting of pte-mapped
      THPs is too difficult (so consistently avoided); but Mlocked accounting
      of only-pmd-mapped THPs is supposed to work, even when multiple mappings
      are mlocked and munlocked or munmapped.  Refine the tests.
      
      There is already a VM_BUG_ON_PAGE(PageDoubleMap) in page_mlock(), so
      page_mlock_one() does not even have to worry about that complication.
      
      (I said the kernel recovers: but would page reclaim be likely to split
      THP before rediscovering that it's VM_LOCKED? I've not followed that up)

      Pull more perf tool updates from Arnaldo Carvalho de Melo:
       "New features:
      
         - Enable use of BPF counters with 'perf stat --for-each-cgroup',
           using per-CPU 'cgroup-switch' events with an attached BPF program
           that does aggregation per-cgroup in the kernel instead of using
           per-cgroup perf events.
      
         - Add Topdown metrics L2 events as default events in 'perf stat' for
           systems having those events.
      
        Hardware tracing:
      
         - Add a config for max loops without consuming a packet in the Intel
           PT packet decoder, set via 'perf config intel-pt.max-loops=N'
      
        Hardware enablement:
      
         - Disable misleading NMI watchdog message in 'perf stat' on hybrid
           systems such as Intel Alder Lake.
      
         - Add a dummy event on hybrid systems to collect metadata records.
      
         - Add 24x7 nest metric events for the Power10 platform.
      
        Fixes:
      
         - Fix event parsing for PMUs starting with the same prefix.
      
         - Fix the 'perf trace' 'trace' alias installation dir.
      
         - Fix buffer size to report iregs in perf script python scripts,
           supporting the extended registers in PowerPC.
      
         - Fix overflow in elf_sec__is_text().
      
         - Fix 's' on source line when disasm is empty in the annotation TUI,
           accessible via 'perf annotate', 'perf report' and 'perf top'.
      
         - Plug leaks in scandir() returned dirent entries in 'perf test' when
           sorting the shell tests.
      
         - Fix --task and --stat with pipe input in 'perf report'.
      
         - Fix 'perf probe' use of debuginfo files by build id.
      
         - If a DSO has both dynsym and symtab ELF sections, read from both
           when loading the symbol table, fixing a problem processing Fedora
           32 glibc DSOs.
      
        Libraries:
      
         - Add grouping of events to libperf, from code in tools/perf,
           allowing libperf users to use that mode.
      
        Misc:
      
         - Filter plt stubs from the 'perf probe --functions' output.
      
         - Update UAPI header copies for asound, DRM, mman-common.h and the
           ones affected by the quotactl_fd syscall"

      mm/page_alloc: Revert pahole zero-sized workaround · 6bce2443
      Mel Gorman authored
      Commit dbbee9d5 ("mm/page_alloc: convert per-cpu list protection to
      local_lock") folded in a workaround patch for pahole that was unable to
      deal with zero-sized percpu structures.
      
      A superior workaround is achieved with commit a0b8200d ("kbuild:
      skip per-CPU BTF generation for pahole v1.18-v1.21").
      
      This patch reverts the dummy field and the pahole version check.

      Pull more s390 updates from Vasily Gorbik:
      
       - Fix preempt_count initialization.
      
       - Rework call_on_stack() macro to add proper type handling and avoid
         possible register corruption.
      
       - More error prone "register asm" removal and fixes.
      
       - Fix syscall restarting when multiple signals are coming in. This adds
         minimalistic trampolines to vdso so we can return from signal without
         using the stack which requires pgm check handler hacks when NX is
         enabled.
      
       - Remove HAVE_IRQ_EXIT_ON_IRQ_STACK since this is no longer true after
         switch to generic entry.
      
       - Fix protected virtualization secure storage access exception
         handling.
      
       - Make machine check C handler always enter with DAT enabled and move
         register validation to C code.
      
       - Fix tinyconfig boot problem by avoiding MONITOR CALL without
         CONFIG_BUG.
      
       - Increase asm symbols alignment to 16 to make it consistent with
         compilers.
      
       - Enable concurrent access to the CPU Measurement Counter Facility.
      
       - Add support for dynamic AP bus size limit and rework ap_dqap to deal
         with messages greater than recv buffer.

           test targets.

        Don't abuse pfn_valid() to check if pfn is in RAM
      
        The semantics of pfn_valid() is to check presence of the memory map
        for a PFN and not whether a PFN is in RAM. The memory map may be
        present for a hole in the physical memory and if such hole corresponds
        to an MMIO range, __arm_ioremap_pfn_caller() will produce a WARN() and
        fail.
