^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 9) It is an unfortunate fact of life that hardware is often produced with
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 10) so-called "errata", which can cause it to deviate from the architecture
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 11) under specific circumstances. For hardware produced by ARM, these
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 12) errata are broadly classified into the following categories:
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 13)
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 14) ========== ========================================================
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 15) Category A A critical error without a viable workaround.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 16) Category B A significant or critical error with an acceptable
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 17) workaround.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 18) Category C A minor error that is not expected to occur under normal
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 19) operation.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 20) ========== ========================================================
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 21)
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 22) For more information, consult one of the "Software Developers Errata
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 23) Notice" documents available on infocenter.arm.com (registration
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 24) required).
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 25)
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 26) As far as Linux is concerned, Category B errata may require some special
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 27) treatment in the operating system. For example, avoiding a particular
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 28) sequence of code, or configuring the processor in a particular way. A
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 29) less common situation may require similar actions in order to declassify
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 30) a Category A erratum into a Category C erratum. These are collectively
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 31) known as "software workarounds" and are only required in the minority of
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 32) cases (e.g. those cases that both require a non-secure workaround *and*
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 33) can be triggered by Linux).
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 34)
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 35) For software workarounds that may adversely impact systems unaffected by
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 36) the erratum in question, a Kconfig entry is added under "Kernel
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 37) Features" -> "ARM errata workarounds via the alternatives framework".
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 38) These are enabled by default and patched in at runtime when an affected
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 39) CPU is detected. For less-intrusive workarounds, a Kconfig option is not
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 40) available and the code is structured (preferably with a comment) in such
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 41) a way that the erratum will not be hit.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 42)
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 43) This approach can make it slightly onerous to determine exactly which
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 44) errata are worked around in an arbitrary kernel source tree, so this
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 45) file acts as a registry of software workarounds in the Linux Kernel and
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 46) will be updated when new workarounds are committed and backported to
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 47) stable kernels.
