*	Update company name	Sebastian Huber	2023-05-20	1	-1/+1
\| \| \| \| \|	The embedded brains GmbH & Co. KG is the legal successor of embedded brains GmbH.
*	libtrace: Move _Record_Stream_header_initialize()	Sebastian Huber	2020-11-09	1	-106/+0
\| \| \| \|	This fixes the build if no function sections are used.
*	Canonicalize config.h include	Sebastian Huber	2020-04-16	1	-1/+1
\| \| \| \| \| \| \| \|	Use the following variant which was already used by most source files: #ifdef HAVE_CONFIG_H #include "config.h" #endif
*	record: Add system events	Sebastian Huber	2019-08-30	1	-3/+69
\| \| \| \| \| \| \|	Add system events to identify the target system. Add system events to transfer blocks of memory and register sets. Update #3665.
*	record: Introduce <rtems/recordserver.h>	Sebastian Huber	2019-08-28	1	-0/+1
\| \| \| \| \| \| \|	This helps to get rid of the <rtems/rtems/tasks.h> dependency in <rtems/record.h>. Update #3665.
*	record: Use BSS section instead of per-CPU data	Sebastian Huber	2019-08-28	1	-1/+1
\| \| \| \| \| \| \| \| \| \| \|	The .rtemsrwset section is used for the per-CPU data. This section has loadable content. Place the ring buffers in the BSS section to avoid large executable image sizes. Not using the per-CPU data makes it possible to initialize the record support earlier. Update #3665.
*	record: Fix thread names on 64-bit targets	Sebastian Huber	2019-08-27	1	-1/+4
\| \| \| \| \| \|	Also fixes the thread names on signed char targets. Update #3665.
*	record: Fix off by one error	Sebastian Huber	2019-08-26	1	-1/+1
\|
*	record: Change thread name encoding	Sebastian Huber	2019-08-06	1	-1/+1
\| \| \| \|	This scheme is easier to decode.
*	record: Add support for thread names	Sebastian Huber	2019-07-30	1	-0/+70

*	rtems: Add rtems_scheduler_get_processor_maximum()	Sebastian Huber	2019-04-09	1	-1/+1
\| \| \| \| \| \| \| \| \| \| \|	Add rtems_scheduler_get_processor_maximum() as a replacement for rtems_get_processor_count(). The rtems_get_processor_count() is a bit orphaned. Adopt it by the Scheduler Manager. The count is also misleading, since the processor set may have gaps and the actual count of online processors may be less than the value returned by rtems_get_processor_count(). Update #3732.
*	record: Rename internal per-CPU events	Sebastian Huber	2019-03-12	1	-1/+1
\| \| \| \|	Update #3665.
*	Add low level event recording support	Sebastian Huber	2019-01-29	1	-0/+290
	Add low level event recording infrastructure for system and user defined events. The infrastructure is able to record high frequency events such as * SMP lock acquire/release, * interrupt entry/exit, * thread switches, * UMA zone allocate/free, and * Ethernet packet input/output, etc. It allows post-mortem analysis in fatal error handlers, e.g. the last events are in the record buffer, the newest event overwrites the oldest event. It is possible to detect record buffer overflows for consumers that expect a continuous stream of events, e.g. to display the system state in real-time. The implementation supports high-end SMP machines (more than 1GHz processor frequency, more than four processors). Add a new API instead. The implementation uses per-processor data structures and no atomic read-modify-write operations. It is uses per-processor ring buffers to record the events. The CPU counter is used to get the time of events. It is combined with periodic uptime events to synchronize it with CLOCK_REALTIME. The existing capture engine tries to solve this problem also, but its performance is not good enough for high-end production systems. The main issues are the variable-size buffers and the use of SMP locks for synchronization. To fix this, the API would change significantly. Update #3665.
