      pstore: Properly assign mem_type property · beca3e31
      Luca Stefani authored
      If mem-type is specified in the device tree
      it would end up overriding the record_size
      field instead of populating mem_type.
      
      As record_size is currently parsed after the
      improper assignment with default size 0 it
      continued to work as expected regardless of the
      value found in the device tree.
      
      Simply changing the target field of the struct
      is enough to get mem-type working as expected.

      pstore: Make sure CONFIG_PSTORE_PMSG selects CONFIG_RT_MUTEXES · 2f4fec59
      John Stultz authored
      In commit 76d62f24 ("pstore: Switch pmsg_lock to an rt_mutex
      to avoid priority inversion") I changed a lock to an rt_mutex.
      
      However, its possible that CONFIG_RT_MUTEXES is not enabled,
      which then results in a build failure, as the 0day bot detected:
        https://lore.kernel.org/linux-mm/202212211244.TwzWZD3H-lkp@intel.com/
      
      Thus this patch changes CONFIG_PSTORE_PMSG to select
      CONFIG_RT_MUTEXES, which ensures the build will not fail.

       "perf tools fixes and improvements:
      
         - Don't stop building perf if python setuptools isn't installed, just
           disable the affected perf feature.
      
         - Remove explicit reference to python 2.x devel files, that warning
           is about python-devel, no matter what version, being unavailable
           and thus disabling the linking with libpython.
      
         - Don't use -Werror=switch-enum when building the python support that
           handles libtraceevent enumerations, as there is no good way to test
           if some specific enum entry is available with the libtraceevent
           installed on the system.

           systems such as yocto that set CC to, e.g.: "gcc --sysroot=/a/b/c".

           tigerlake, westmereep-dp, westmereep-sp, westmereex.
      
         - Add vendor events files (JSON) for AMD Zen 4, from sections
           2.1.15.4 "Core Performance Monitor Counters", 2.1.15.5 "L3 Cache
           Performance Monitor Counter"s and Section 7.1 "Fabric Performance
           Monitor Counter (PMC) Events" in the Processor Programming
           Reference (PPR) for AMD Family 19h Model 11h Revision B1
           processors.
      
           This constitutes events which capture op dispatch, execution and
           retirement, branch prediction, L1 and L2 cache activity, TLB
           activity, L3 cache activity and data bandwidth for various links
           and interfaces in the Data Fabric.
      
         - Also, from the same PPR are metrics taken from Section 2.1.15.2
           "Performance Measurement", including pipeline utilization, which
           are new to Zen 4 processors and useful for finding performance
           bottlenecks by analyzing activity at different stages of the
           pipeline.
      
         - Greatly improve the 'srcline', 'srcline_from', 'srcline_to' and
           'srcfile' sort keys performance by postponing calling the external
           addr2line utility to the collapse phase of histogram bucketing.
      
         - Fix 'perf test' "all PMU test" to skip parametrized events, that
           requires setting up and are not supported by this test.

      perf python: Fix splitting CC into compiler and options · 09e6f9f9
      Arnaldo Carvalho de Melo authored
      Noticed this build failure on archlinux:base when building with clang:
      
        clang-14: error: optimization flag '-ffat-lto-objects' is not supported [-Werror,-Wignored-optimization-argument]
      
      In tools/perf/util/setup.py we check if clang supports that option, but
      since commit 3cad53a6 ("perf python: Account for multiple words
      in CC") this got broken as in the common case where CC="clang":
      
        >>> cc="clang"
        >>> print(cc.split()[0])
        clang
        >>> option="-ffat-lto-objects"
        >>> print(str(cc.split()[1:]) + option)
        []-ffat-lto-objects
        >>>
      
      And then the Popen will call clang with that bogus option name that in
      turn will not produce the b"unknown argument" or b"is not supported"
      that this function uses to detect if the option is not available and
      thus later on clang will be called with an unknown/unsupported option.
      
      Fix it by looking if really there are options in the provided CC
      variable, and if so override 'cc' with the first token and append the
      options to the 'option' variable.

      afs: Stop implementing ->writepage() · a9eb558a
      David Howells authored
      We're trying to get rid of the ->writepage() hook[1].  Stop afs from using
      it by unlocking the page and calling afs_writepages_region() rather than
      folio_write_one().
      
      A flag is passed to afs_writepages_region() to indicate that it should only
      write a single region so that we don't flush the entire file in
      ->write_begin(), but do add other dirty data to the region being written to
      try and reduce the number of RPC ops.
      
      This requires ->migrate_folio() to be implemented, so point that at
      filemap_migrate_folio() for files and also for symlinks and directories.
      
      This can be tested by turning on the afs_folio_dirty tracepoint and then
      doing something like:
      
         xfs_io -c "w 2223 7000" -c "w 15000 22222" -c "w 23 7" /afs/my/test/foo
      
      and then looking in the trace to see if the write at position 15000 gets
      stored before page 0 gets dirtied for the write at position 23.

      afs: Fix lost servers_outstanding count · 36f82c93
      David Howells authored
      The afs_fs_probe_dispatcher() work function is passed a count on
      net->servers_outstanding when it is scheduled (which may come via its
      timer).  This is passed back to the work_item, passed to the timer or
      dropped at the end of the dispatcher function.
      
      But, at the top of the dispatcher function, there are two checks which
      skip the rest of the function: if the network namespace is being destroyed
      or if there are no fileservers to probe.  These two return paths, however,
      do not drop the count passed to the dispatcher, and so, sometimes, the
      destruction of a network namespace, such as induced by rmmod of the kafs
      module, may get stuck in afs_purge_servers(), waiting for
      net->servers_outstanding to become zero.
      
      Fix this by adding the missing decrements in afs_fs_probe_dispatcher().
