      i2c: pasemi: Wait for write xfers to finish · bd8963e6
      Martin Povišer authored
      Wait for completion of write transfers before returning from the driver.
      At first sight it may seem advantageous to leave write transfers queued
      for the controller to carry out on its own time, but there's a couple of
      issues with it:
      
       * Driver doesn't check for FIFO space.
      
       * The queued writes can complete while the driver is in its I2C read
         transfer path which means it will get confused by the raising of
         XEN (the 'transaction ended' signal). This can cause a spurious
         ENODATA error due to premature reading of the MRXFIFO register.
      
      Adding the wait fixes some unreliability issues with the driver. There's
      some efficiency cost to it (especially with pasemi_smb_waitready doing
      its polling), but that will be alleviated once the driver receives
      interrupt support.

       "Here are two small driver core changes for 5.18-rc2.
      
        They are the final bits in the removal of the default_attrs field in

        changes to do this came in through different development trees, and
        then one new user snuck in. So this series has two changes:
      
         - removal of the default_attrs field in the powerpc/pseries/vas code.
      
           The change has been acked by the PPC maintainers to come through
           this tree
      
         - removal of default_attrs from struct kobj_type now that all
           in-kernel users are removed.
      
           This cleans up the kobject code a little bit and removes some
           duplicated functionality that confused people (now there is only
           one way to do default groups)

      perf doesn't read stderr then progress stops with perf waiting for

      Michael Petlan authored
      The `perf --list-cmds` output prints only internal commands, although
      there is no reason for that from users' perspective.
      
      Adding the external commands to commands array with NULL function
      pointer allows printing all perf commands while not changing the logic

      perf bench: Fix epoll bench to correct usage of affinity for machines with #CPUs > 1K · 299687e1
      Athira Rajeev authored
      The 'perf bench epoll' testcase fails on systems with more than 1K CPUs.
      
      Testcase: perf bench epoll all
      
      Result snippet:
      <<>>
      Run summary [PID 106497]: 1399 threads monitoring on 64 file-descriptors for 8 secs.
      
      perf: pthread_create: No such file or directory
      <<>>
      
      In epoll benchmarks (ctl, wait) pthread_create is invoked in do_threads
      from respective bench_epoll_*  function. Though the logs shows direct
      failure from pthread_create, the actual failure is from
      "sched_setaffinity" returning EINVAL (invalid argument).
      
      This happens because the default mask size in glibc is 1024. To overcome
      this 1024 CPUs mask size limitation of cpu_set_t, change the mask size
      using the CPU_*_S macros.
      
      Patch addresses this by fixing all the epoll benchmarks to use CPU_ALLOC
      to allocate cpumask, CPU_ALLOC_SIZE for size, and CPU_SET_S to set the
      mask.

      don't allow opening the file unless one of the events has
      PERF_SAMPLE_DATA_SRC set.
      
      SPE doesn't have this set even though synthetic memory data is generated
      after it is decoded. Fix this issue by setting DATA_SRC on SPE events.
      This has no effect on the data collected because the SPE driver doesn't
      do anything with that flag and doesn't generate samples.

      perf unwind: Don't show unwind error messages when augmenting frame pointer stack · fa7095c5
      James Clark authored
      Commit Fixes: b9f6fbb3 ("perf arm64: Inject missing frames when
      using 'perf record --call-graph=fp'") intended to add a 'best effort'
      DWARF unwind that improved the frame pointer stack in most scenarios.
      
      It's expected that the unwind will fail sometimes, but this shouldn't be
      reported as an error. It only works when the return address can be
      determined from the contents of the link register alone.
      
      Fix the error shown when the unwinder requires extra registers by adding
      a new flag that suppresses error messages. This flag is not set in the
      normal --call-graph=dwarf unwind mode so that behavior is not changed.

      perf test tsc: Fix error message when not supported · 290fa68b
      Chengdong Li authored
      By default `perf test tsc` does not return the error message when the
      child process detected kernel does not support it. Instead, the child
      process prints an error message to stderr, unfortunately stderr is
      redirected to /dev/null when verbose <= 0.
      
      This patch does:
      
      - return TEST_SKIP to the parent process instead of TEST_OK when
        perf_read_tsc_conversion() is not supported.
      
      - Add a new subtest of testing if TSC is supported on current
        architecture by moving exist code to a separate function.
        It avoids two places in test__perf_time_to_tsc() that return
        TEST_SKIP by doing this.
      
      - Extend the test suite definition to contain above two subtests.
        Current test_suite and test_case structs do not support printing skip
        reason when the number of subtest less than 1. To print skip reason, it
        is necessary to extend current test suite definition.

      perf python: Fix probing for some clang command line options · dd6e1fe9
      Arnaldo Carvalho de Melo authored
      The clang compiler complains about some options even without a source
      file being available, while others require one, so use the simple
      tools/build/feature/test-hello.c file.
      
      Then check for the "is not supported" string in its output, in addition
      to the "unknown argument" already being looked for.
      
      This was noticed when building with clang-13 where -ffat-lto-objects
      isn't supported and since we were looking just for "unknown argument"
      and not providing a source code to clang, was mistakenly assumed as
      being available and not being filtered to set of command line options
      provided to clang, leading to a build failure.

      Yes, I think that is probably the best solution. As far as I can tell,
      at least in this file and context, the warning appears harmless, as the
      "create a GNU C statement expression from two different macros" is very
      much intentional, based on the presence of PERL_USE_GCC_BRACE_GROUPS.
      The warning is fixed in upstream Perl by just avoiding creating GNU C
      statement expressions using STMT_START and STMT_END:
      
        https://github.com/Perl/perl5/issues/18780
        https://github.com/Perl/perl5/pull/18984
      
      If I am reading the source code correctly, an alternative to disabling
      the warning would be specifying -DPERL_GCC_BRACE_GROUPS_FORBIDDEN but it
      seems like that might end up impacting more than just this site,
      according to the issue discussion above.

      tools build: Use $(shell ) instead of `` to get embedded libperl's ccopts · 541f695c
      Arnaldo Carvalho de Melo authored
      Just like its done for ldopts and for both in tools/perf/Makefile.config.
      
      Using `` to initialize PERL_EMBED_CCOPTS somehow precludes using:
      
        $(filter-out SOMETHING_TO_FILTER,$(PERL_EMBED_CCOPTS))
      
      And we need to do it to allow for building with versions of clang where
      some gcc options selected by distros are not available.
