2021-02-27	getgrent.c, record-client.c: Add missing includes for assert.h	Vijay Kumar Banerjee	1	-0/+1

2021-02-26	record-client.c: Fix Unchecked return value (CID #1456677)	Ryan Long	1	-1/+3
	CID 1456677: Unchecked return value in resolve_hold_back(). Closes #4260
2020-04-16	Canonicalize config.h include	Sebastian Huber	1	-1/+1
	Use the following variant which was already used by most source files: #ifdef HAVE_CONFIG_H #include "config.h" #endif
2019-08-27	record: Add data size to client	Sebastian Huber	1	-0/+8
	This is necessary to get the thread names properly on 32-bit and 64-bit targets. Update #3665.
2019-08-26	record: Improve overflow handling	Sebastian Huber	1	-25/+58
	Signal the accumulated item overflow count with the time of the first new item.
2019-08-17	record: Pass bintime to client handlers	Sebastian Huber	1	-8/+1
	This is a minor optimization.
2019-08-17	record: Simplify client visit()	Sebastian Huber	1	-14/+24

2019-08-17	record: Remove superfluous cast	Sebastian Huber	1	-1/+1

2019-08-17	record: Increase client robustness	Sebastian Huber	1	-10/+33
	Do nothing after errors.
2019-08-17	record: Improve overflow handling	Sebastian Huber	1	-9/+198
	In case of a ring buffer overflow, the rtems_record_drain() will push the complete ring buffer content to the client. While the items are processed by the client, new items may overwrite some items being processed. The overwritten items can be detected in the following iteration once the next tail/head information is pushed to the client.
2019-08-16	record: Detect also large overflows	Sebastian Huber	1	-18/+33

2019-08-16	record: Simplify rtems_record_client_context	Sebastian Huber	1	-17/+27

2019-03-12	record: Rename internal per-CPU events	Sebastian Huber	1	-4/+4
	Update #3665.
2019-01-29	Add low level event recording support	Sebastian Huber	1	-0/+448
	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.
