Event Recording Configuration
=============================
This section describes configuration options related to the event recording.
.. index:: CONFIGURE_RECORD_EXTENSIONS_ENABLED
.. _CONFIGURE_RECORD_EXTENSIONS_ENABLED:
CONFIGURE_RECORD_EXTENSIONS_ENABLED
-----------------------------------
CONSTANT:
``CONFIGURE_RECORD_EXTENSIONS_ENABLED``
OPTION TYPE:
This configuration option is a boolean feature define.
DEFAULT CONFIGURATION:
If this configuration option is undefined, then the described feature is not
enabled.
DESCRIPTION:
In case
* this configuration option is defined
* and :ref:`CONFIGURE_RECORD_PER_PROCESSOR_ITEMS` is properly defined,
then the event record extensions are enabled.
NOTES:
The record extensions capture thread create, start, restart, delete, switch,
begin, exitted and terminate events.
.. index:: CONFIGURE_RECORD_FATAL_DUMP_BASE64
.. _CONFIGURE_RECORD_FATAL_DUMP_BASE64:
CONFIGURE_RECORD_FATAL_DUMP_BASE64
----------------------------------
CONSTANT:
``CONFIGURE_RECORD_FATAL_DUMP_BASE64``
OPTION TYPE:
This configuration option is a boolean feature define.
DEFAULT CONFIGURATION:
If this configuration option is undefined, then the described feature is not
enabled.
DESCRIPTION:
In case
* this configuration option is defined
* and :ref:`CONFIGURE_RECORD_PER_PROCESSOR_ITEMS` is properly defined,
* and :ref:`CONFIGURE_RECORD_FATAL_DUMP_BASE64_ZLIB` is undefined,
then the event records are dumped in Base64 encoding in a fatal error
extension (see :ref:`Terminate`).
NOTES:
This extension can be used to produce crash dumps.
.. index:: CONFIGURE_RECORD_FATAL_DUMP_BASE64_ZLIB
.. _CONFIGURE_RECORD_FATAL_DUMP_BASE64_ZLIB:
CONFIGURE_RECORD_FATAL_DUMP_BASE64_ZLIB
---------------------------------------
CONSTANT:
``CONFIGURE_RECORD_FATAL_DUMP_BASE64_ZLIB``
OPTION TYPE:
This configuration option is a boolean feature define.
DEFAULT CONFIGURATION:
If this configuration option is undefined, then the described feature is not
enabled.
DESCRIPTION:
In case
* this configuration option is defined
* and :ref:`CONFIGURE_RECORD_PER_PROCESSOR_ITEMS` is properly defined,
then the event records are compressed by zlib and dumped in Base64 encoding
in a fatal error extension (see :ref:`Terminate`).
NOTES:
The zlib compression needs about 512KiB of RAM. This extension can be used
to produce crash dumps.
.. index:: CONFIGURE_RECORD_PER_PROCESSOR_ITEMS
.. _CONFIGURE_RECORD_PER_PROCESSOR_ITEMS:
CONFIGURE_RECORD_PER_PROCESSOR_ITEMS
------------------------------------
CONSTANT:
``CONFIGURE_RECORD_PER_PROCESSOR_ITEMS``
OPTION TYPE:
This configuration option is an integer define.
DEFAULT VALUE:
The default value is 0.
VALUE CONSTRAINTS:
The value of this configuration option shall satisfy all of the following
constraints:
* It shall be greater than or equal to 16.
* It shall be less than or equal to `SIZE_MAX <https://en.cppreference.com/w/c/types/limits>`_.
* It shall be a power of two.
* It shall be less than or equal to a
BSP-specific and application-specific value which depends on the size of the
memory available to the application.
DESCRIPTION:
The value of this configuration option defines the event record item count
per processor.
NOTES:
The event record buffers are statically allocated for each configured
processor (:ref:`CONFIGURE_MAXIMUM_PROCESSORS`). If the value of this
configuration option is zero, then nothing is allocated.
