Event Recording Configuration
|
|
=============================
|
|
|
|
This section describes configuration options related to the event recording.

|
|
|
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.

DEFAULT CONFIGURATION:
|
|
If this configuration option is undefined, then the described feature is not
|

enabled.
|

DESCRIPTION:

|
|
|
|
* 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.

|
|
* 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.

|
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.
