Silicon Errata and Software Workarounds
|
|
=======================================
|
|
|
|
Author: Will Deacon <will.deacon@arm.com>

Date : 27 November 2015

|
|
|
It is an unfortunate fact of life that hardware is often produced with
|
|
so-called "errata", which can cause it to deviate from the architecture
|
|
under specific circumstances. For hardware produced by ARM, these
|
|
errata are broadly classified into the following categories:
|
|
|
|
========== ========================================================
|
|
Category A A critical error without a viable workaround.
|
|
Category B A significant or critical error with an acceptable
|
|
workaround.
|
|
Category C A minor error that is not expected to occur under normal
|
|
operation.
|
|
========== ========================================================
|
|
|
|
For more information, consult one of the "Software Developers Errata
|
|
Notice" documents available on infocenter.arm.com (registration
|
|
required).
|
|
|
|
As far as Linux is concerned, Category B errata may require some special
|
|
treatment in the operating system. For example, avoiding a particular
|
|
sequence of code, or configuring the processor in a particular way. A
|
|
less common situation may require similar actions in order to declassify
|
|
a Category A erratum into a Category C erratum. These are collectively
|
|
known as "software workarounds" and are only required in the minority of
|
|
cases (e.g. those cases that both require a non-secure workaround *and*
|
|
can be triggered by Linux).
|
|
|
|
For software workarounds that may adversely impact systems unaffected by
|
|
the erratum in question, a Kconfig entry is added under "Kernel
|
|
Features" -> "ARM errata workarounds via the alternatives framework".
|
|
These are enabled by default and patched in at runtime when an affected
|
|
CPU is detected. For less-intrusive workarounds, a Kconfig option is not
|
|
available and the code is structured (preferably with a comment) in such
|
|
a way that the erratum will not be hit.
|
|
|
|
This approach can make it slightly onerous to determine exactly which
|
|
errata are worked around in an arbitrary kernel source tree, so this
|
|
file acts as a registry of software workarounds in the Linux Kernel and
|
|
will be updated when new workarounds are committed and backported to
|
|
stable kernels.
