      [PATCH] ppc32: Tell userland about lack of standard TB · d8e998c5
      Benjamin Herrenschmidt 提交于
      Glibc is about to get some new high precision timer stuff that relies on
      the standard timebase of the PPC architecture.
      
      However, some (rare & old) CPUs do not have such timebase and it is a
      bit annoying to have your stuff just crash because you are running on
      the wrong CPU...
      
      This exposes to userland a CPU feature bit that tells that the current
      processor doesn't have a standard timebase.  It's negative logic so that
      glibc will still "just work" on older kernels (it will just be unhappy
      on those old CPUs but that doesn't really matter as distro tend to
      update glibc & kernel at the same time).
