|
<para>This section describes the data formats used to report events and
|
|
|
|
errors from RTAS to the OS. A common format is used for errors and events
|
|
|
|
to simplify software both in RTAS and in the OS. Both errors and events
|
|
|
|
may have been analyzed to some degree by RTAS, and value judgments may
|
|
|
|
have been applied to decide how serious an error is, or even how to
|
|
|
|
describe it to the OS. These judgments are made by platform providers,
|
|
|
|
since only they know enough about the hardware to decide how serious a
|
|
|
|
problem it is, whether and how to recover from it, and how to map it onto
|
|
|
|
the abstracted set of events and errors that a system is required to know
|
|
|
|
about. There will be cases with some platforms where no reasonable
|
|
|
|
mapping exists, and platform features may not be fully supported by the
|
|
|
|
OS. In such cases, error reports may also be non-specific, leaving
|
|
|
|
platform-specific details to platform-aware software.</para>
