   9 It is an unfortunate fact of life that hardware is often produced with
  10 so-called "errata", which can cause it to deviate from the architecture
  11 under specific circumstances.  For hardware produced by ARM, these
  12 errata are broadly classified into the following categories:
  13
  14   ==========  ========================================================
  15   Category A  A critical error without a viable workaround.
  16   Category B  A significant or critical error with an acceptable
  17               workaround.
  18   Category C  A minor error that is not expected to occur under normal
  19               operation.
  20   ==========  ========================================================
  21
  22 For more information, consult one of the "Software Developers Errata
  23 Notice" documents available on infocenter.arm.com (registration
  24 required).
  25
  26 As far as Linux is concerned, Category B errata may require some special
  27 treatment in the operating system. For example, avoiding a particular
  28 sequence of code, or configuring the processor in a particular way. A
  29 less common situation may require similar actions in order to declassify
  30 a Category A erratum into a Category C erratum. These are collectively
  31 known as "software workarounds" and are only required in the minority of
  32 cases (e.g. those cases that both require a non-secure workaround *and*
  33 can be triggered by Linux).
  34
  35 For software workarounds that may adversely impact systems unaffected by
  36 the erratum in question, a Kconfig entry is added under "Kernel
  37 Features" -> "ARM errata workarounds via the alternatives framework".
  38 With the exception of workarounds for errata deemed "rare" by Arm, these
  39 are enabled by default and patched in at runtime when an affected CPU is
  40 detected. For less-intrusive workarounds, a Kconfig option is not
  41 available and the code is structured (preferably with a comment) in such
  42 a way that the erratum will not be hit.
  43
  44 This approach can make it slightly onerous to determine exactly which
  45 errata are worked around in an arbitrary kernel source tree, so this
  46 file acts as a registry of software workarounds in the Linux Kernel and
  47 will be updated when new workarounds are committed and backported to
  48 stable kernels.
