      tools: Remove feature-sync-compare-and-swap feature detection · 60fa754b
      Leo Yan 提交于
      Since the __sync functions have been removed from perf, it's needless
      for perf tool to test the feature sync-compare-and-swap.
      
      The feature test is not used by any other components, remove it.

      perf auxtrace: Remove auxtrace_mmap__read_snapshot_head() · 9d645033
      Leo Yan 提交于
      Since the function auxtrace_mmap__read_snapshot_head() is exactly same
      with auxtrace_mmap__read_head(), whether the session is in snapshot mode
      or not, it's unified to use function auxtrace_mmap__read_head() for
      reading AUX buffer head.
      
      And the function auxtrace_mmap__read_snapshot_head() is unused so this
      patch removes it.

      perf auxtrace: Drop legacy __sync functions · 1fc7e593
      Leo Yan 提交于
      The main purpose for using __sync built-in functions is to support
      compat mode for 32-bit perf with 64-bit kernel.  But using these
      built-in functions might cause potential issues.
      
      __sync functions originally support Intel Itanium processoer [1] but it
      cannot promise to support all 32-bit archs.  Now these functions have
      become the legacy functions.
      
      Considering __sync functions cannot really fix the 64-bit value
      atomicity on 32-bit archs, thus this patch drops __sync functions.
      
      Credits to Peter for detailed analysis.

      perf script python: Fix unintended underline · b7ae6d43
      Stephen Brennan 提交于
      The text ranging from "subsystem__event_name" to "raw_syscalls__sys_enter()"
      is interpreted by asciidoc as a pair of unconstrained text formatting markers.
      
      The result is that the manual page displayed this text as underlined,
      and the HTML pages displayed this text as italicized. Escape the first
      double-underscore to prevent this.

      perf cs-etm: Add warnings for missing DSOs · 9c38b671
      James Clark 提交于
      Currently decode will silently fail if no binary data is available for
      the decode. This is made worse if only partial data is available because
      the decode will appear to work, but any trace from that missing DSO will
      silently not be generated.
      
      Add a UI popup once if there is any data missing, and then warn in the
      bottom left for each individual DSO that's missing.
