- New slicing based on equipmentId + linkId indexing, to allow proper STF formatting when replaying data from single file with multiple CRUids.
- Cosmetics fix release.
- Updated configuration parameters:
- equipment-rorc-*.linkMask : default value changed to 0-11 (instead of 0-31). There was a change in ReadoutCard, which now uses numbering of links 0-11 for each CRU end-point, and creates an exception when outside of this range.
- Improved error reporting when FairMQChannel consumer memory settings cause runtime issues (eg pages too small).
- Fix issue in file replay, data size was zero (readout>=v1.2, autochunk=off).
- readRaw.exe:
- fixed printing offset in lz4 files.
- added options:
- dumpDataInline: if set, each packet raw content is printed (hex dump style).
- fileReadVerbose: if set, more information is printed when reading/decoding file. By default, file size/chunking printouts are now off.
- Updated configuration parameters:
- added readout.memoryPoolStatsEnabled, to print debug information on memory pages usage.
- added equipment-*.debugFirstPages, to print debug information for first (given number of) data pages readout.
- Updated configuration parameters:

- receiver-fmq-*.decodingMode : readout mode replaced by stfHbf and stfSuperpage.
- Added utilities testTxPerfFMQ / testRxPerfFMQ
- Memory banks: 1 page should be kept for metadata. readoutAutoConfigure updated accordingly.

- Updated configuration parameters:
- readout.aggregatorStfTimeout: if set, STF buffered until timeout, so that slices of all sources sent together. This requires enough memory buffer for the corresponding amount of time.
- Updated configuration parameters:
- removed equipment-rorc-*.resetLevel : the reset is now handled internally by ReadoutCard driver.
- Monitoring: statistics are tagged with Readout tag.
- RDH version updated to RDHv6 (also works with RDHv5). It is NOT backward compatible: features making use of the RDH (e.g. timeframe identification) will NOT work with this version of readout.
- FairLogger dependency update
- FairLogger dependency update
- Updated configuration parameters:
- added equipment-rorc-*.rdhDumpWarningEnabled : disabled by default. For checks concerning e.g. timeframe ID continuity and link consistency in data page.
- consumer-FairMQChannel: channel bind failure is now fatal for the consumer, and associated memory bank will not be created.
- consumer-zmq: new equipment to stream data from DCS.
- fix RDH struct (PAR fields), and improved checks related to RDH size.

- Updated configuration parameters:
- added equipment-player-*.autoChunkLoop: when set, file is replayed in loop. RDH orbit counters are updated after 1st loop to make a realistic TF sequence.
- Cleanup configuration parameters documentation and editor.
- ReadoutCard dependency is now optional, to allow building readout on platforms where it is not available. If so, equipment-rorc and memoryMappedFile banks features are disabled.
- Updated configuration parameters:
- added readout.timeframeServerUrl: creates a ZMQ server to publish each TF id produced, to serve as reference for other instances producing data without hardware clock.
- ProcessorLZ4Compress: data is no more compressed in-place, but in separate data pages to preserve original data (eg for shipping to data distribution).
- equipment-zmq-*.timeframeClientUrl: when set, data is published only once for each TF id published by remote server. This allows to synchronize DCS data with a remote hardware-driven readout equipment.
- Implementation of the new STF interface (v2). See SubTimeframe.h. This version of readout will not work with older STFB executables.
- RDH is handled in the same way for all equipments (RORC, player, emulator). Same RDH configuration parameters apply to all.

- added consumer-*.filterEquipmentIdsInclude and consumer-*.filterEquipmentIdsExclude to define filters based on equipment ids.
- eventDump: added maxRdhPerPage parameter, to limit the number of RDH printed for each page and reduce verbosity.
- minor release, code and build cleanup.
- Updated configuration parameters:
- added equipment-cruemulator-*.cruId, dpwId, systemId: to set corresponding fields in emulated RDH.
- Added example configuration file to run readout software data generator + stfBuilder.
- readoutAutoConfigure: minor fixes (memory size, stfb fmq-name).
- Fixed compressor libraries linking.
- Updated configuration parameters:
- added consumer-stats.zmqPublishAddress : to publish readout statistics by ZMQ.
- Added readoutMonitor.exe, a server to collect and display statistics published by ZMQ from multiple readout processes.
- readoutAutoConfigure: using virtual ipc address for FMQ. Config generator versioning now indepedent from readout version (now 2.1) for better tracking of generated config files.
- optimized flush of TF buffer on stop.
- Updated configuration parameters:
- changed equipment-player-*.autoChunkLoop: when negative value set, stop the replay after corresponding number of iterations. (e.g. -5 -> 5x replay).
- added readout.tfRateLimit: when set, the output (of the aggregator) is limited to a given timeframe rate.
- added readout.timeStart and readout.timeStop: when set, in standalone mode, readout will execute START and STOP at given time.
- added stats for data pages given to consumer-FMQchannel (number in use, release latency).
- readoutAutoConf v2.1.1
- Adapted to follow o2-flp conventions: renaming of executables, libraries, paths. In particular, readout.exe is now o2-readout-exe.

- Added run number tag to monitoring metrics.
- Fix for automatic logging to console.
- o2-readout-eventdump: added options dumpRdh / dumpPayload.
- o2-readout-rawreader: added print of RDH field systemId.
- Aggregator: extended cleanup (fix start/stop cycles), TF flushing (fix dicard warning on stop when multiple euipments).

- receiver-fmq: added option releaseDelay, to add a delay before releasing data pages received.
- o2-readout-monitor: improved formatting.
- consumer-stats: publish/print statistics of memory pages locked by STFB.
- Added rate limit for eventDump: see consumer-zmq.maxRate and consumer-zmq.pagesPerBurst.
- consumer-stats: publish/print the current timeframe Id sent to STFB.
- consumer-stats: ZMQ stats client cleanup timeout, to avoid blocking on exit.
- auto-mute RDH warnings: verbosity reduced if many successive logs done in a short time.
- equipment-player: fixed bug in "autochunk" replay mode. There was a "last packet invalid" error wrongly reported (and aborting replay) in the rare case when a link change would occur exactly at the beginning of a page.
- Default value of equipment-rorc.rdhUseFirstInPageEnabled is now 1 for all RDH equipments (RORC, emu, player).
- FMQ stats not printed when consoleUpdate=1 unless there is a running consumerFMQchannel with disableSending=0.
- tfRateLimit is handled in the equipment directly and avoid potential issues with timeframe slicing at very slow rates.
- equipment-cruemulator: TF id extracted from trigger counters (single timer source for improved coherency).
- Memory allocation policy updated: all readout memory is locked (RAM only, can not be swapped). A warning is reported if not.
- consumer-FMQchannel: checks are done before FMQ shared memory region is created, to avoid going in a state with over-committed memory (no checks done in FMQ library about the validity of the region created, which can cause severe crash when trying to access it). Both /proc/meminfo (MemFree) and /dev/shm (if using shmem transport type) should report enough available memory before proceeding. Memory is also immediately locked and zeroed to avoid later crashes.
- Updated configuration parameters:
- added readout.disableTimefarmes: when set, all timeframe-related features are disabled (STF slicing, TF rate limits, etc). All data are tagged with TF id = 0. To be used for some calibration runs not using a central trigger clock.
- added consumer-FMQchannel.checkResources: controls which resources are checked for fitting unmanaged region. This is a comma-separated list of items to be checked. By default, no checks are done. Recommended value: /dev/shm, MemAvailable.
- verbose logs auto-mute (aggregator, consumer-FMQchannel).
- consumer-FMQchannel: drop TF on error (to avoid unhappy STFB when sending incomplete data, eg on "data page too small" or "no page left" conditions).
- added memory pool usage statistics (to help tuning buffer pages count and size).
- added some ZeroMQ options for consumerZMQ and equipmentZMQ.
- Updated configuration parameters:
- added equipment-.saveErrorPagesMax and equipment-.saveErrorPagesPath to save to disk data pages found with errors (up to given maximum, in given path).
- equipment-*.rdhDumpWarningEnabled default set to 1 (now that RDH warning messages auto-muted on flood).
- o2-readout-rawreader: added print of TF id when RDH dump enabled. To enable this feature, one must specify a value for timeframePeriodOrbits (typically 128 or 256) in the command line parameters. TF ids generated are relative to the beginning of the file.
- Updated configuration parameters:
- added equipment-*.dataPagesLogPath to allow saving to disk summary debug info for all data pages received.
- Fixed spurious "Non-contiguous timeframe IDs" warning: the check was too strict, having some links 1 TF behind is fine.
- Updated configuration parameters:
- equipment.TFperiod is now set to 128 by default, instead of 256 previously. This is the duration of a timeframe, in number of LHC orbits.
- Built-in memory usage reporting for o2-readout-test-fmq-memory
- Added a default configuration file (/etc/o2.d/readout-defaults.cfg) to store some global settings, loaded on process startup. This is independent from the CONFIGURE time configuration file.
- Process memory lock is now disabled by default (saves 2GB of unused FMQ virtual memory created for each channel).
- Fix monitoring statistics: memlocked pages.
- Added linkId in RDH error reporting.
- Error reported when first orbit received by equipments mismatch.
- Updated configuration parameters:
- readout.maxMsgError and readout.maxMsgWarning: when set, readout will stop when reaching the number of error or warning messages defined as threshold.
- Added a howto guide to document some typical use cases.
- Updated readout counters published by ZMQ and added an online status display.
- Updated configuration parameters:
- equipment-cruemulator-*.triggerRate: when set, the equipment HBF rate is limited to given value (eg to emulate slow triggers).
- Fixed verbosity for non-contiguous TF warnings.
- Updated configuration parameters:
- equipment-*-rdhCheckFirstOrbit: when set to zero, readout does not check mismatch of first orbit received by equipments.
- Added bookeeping library test utility
- Use ECS environment variables from occ include file.
- Updated configuration parameters:
- equipment-*-rdhCheckDetectorField: when set, changes in the RDH detector field are reported.
- readout-monitor: added built-in net dispatcher to broadcast readout statistics
- readout-status: configure from readout-defaults file, auto-reconnect to readout-monitor.
- Updated configuration parameters:
- added equipment-*.rdhDumpFirstInPageEnabled: when set to -1, will print the first RDH of the first page (trigger info, etc).
- Minor fix
- Explicit order for resources cleanup on unexpected state machine exit.
- Reset TFid on file replay start/stop loop.
- Added optional database connection to store runtime statistics.
- DB improvements: occ.getRole() workaround for source id, logging.
- Added logging of some EOR stats (TF number, etc) as for bookkeeping.
- o2-readout-monitor: indexing by source for correct rates computation.
- Cosmetics improvements related to threads cleanup order on exit.
- readout-monitor: added log file for received measurements.
- added support for custom commands to be executed on states transitions.
- Updated configuration parameters:
- readout.flushConsumerTimeout: when set, readout waits up to this amount of time that all data pages locked by consumers are released before stopping.
- Added warning message on buffers low.
- Added message at end of run showing the links which have provided data for each equipment and how much per link.
- Updated configuration parameters:
- equipment-file-*.updateOrbits: when set to zero, RDH orbits are not updated in file loop replay. This is needed for some reconstruction tests. This however creates a stream of data with inconsistent orbit ids and mismatching timeframe information.
- Added some buffer monitoring counters. They are logged in console stats and in monitoring (readout.bufferUsage, one per buffer, from 0% to 100%).
- Bug fixed in the readout TF rate regulator (was ineffective after 35 minutes = 2^31 microseconds - wrong variable width in a conversion).
- Changed level of "Bypassing RORC firmware compatibility check", retrograded from support warning to developper info.
- Added orbit counter to stats.
- Updated configuration parameters:
- equipment-*.verbose: adds some extra verbosity.
- equipment-*.ctpMode: enables CTP mode, data is discarded until start of run detected in RDH detector field pattern, and after corresponding end of run is detected.
- consumer-fileRecorder-*.tfMax: when set, recording will stop after reaching given number of timeframes.
- o2-readout-rawreader: added option to dump stats on HBF size.
- Minor release for osx compatibility.
- Updated configuration parameters:
- added consumer-FairMQChannel-*.enablePackedCopy. If set, the same superpage may be reused (space allowing) for the copy of multiple HBF (instead of a separate one for each copy). This allows a reduced memoryPoolNumberOfPages.
- ROC fifo health check enabled, a warning message is logged when in/out ROC FIFOs are empty/full.
- Updated configuration parameters:
- added equipment-*.numaNode. If set, memory / thread will try to use given NUMA node. If "auto", will try to guess it for given equipment (eg ROC). "auto" is default.
- Updated configuration parameters:
- added consumer-FairMQChannel-*.threads. If set, a pool of threads is used for FMQ message formatting. Needed at high rates when a single CPU core is not enough to prepare data for DataDistribution (including overlapping HBF copy).
- Updated configuration parameters:
- consumer-FairMQChannel-*.enablePackedCopy default changed to 1.
- Fix for running without packed copy (was crashing).
- In auto mode, get ROC numa node from /sys/bus/pci/devices because ROC library reports wrong value.
- Fix for DataDistribution multithreaded message formatting: TF ordering could get wrong out of the thread pool after having memory buffer empty.
- equipment-*.rdhCheckFirstOrbit: when set, readout also check consistency of orbits between all the links of an equipment. If not all links/equipments first orbit are the same, readout will interrupt the run.
- Updated configuration parameters:
- added readout.fairmqConsoleSeverity, to set fair::Logger::SetConsoleSeverity
- Explicit log message when reporting error state, in case not reported by state machine
- Added ROC link Id for some log messages, as provided from new superpage metadata link field from ROC library.
- Superpage internal metadata not stored at beginning of page but separately in heap, by default. Behavior can be adjusted with MemoryPool::headerReservedSpace.
- equipment-CruEmulator: set TF trigger type (bit 11) on new TF. Used for dropEmptyHBFramesTriggerMask tests.
- Updated configuration parameters:
- added consumer-fileRecorder-*.dropEmptyHBFramesTriggerMask: when using dropEmptyHBFrames = 1, keep some empty HB frames with trigger type matching given (decimal) mask.
- Added support for RDHv7. Readout already accepts data from equipments with v7, but still generates data (internal sw generator) with v6, for compatibility with current software downstream.
- Updated configuration parameters:
- added equipemnt-*.rdhCheckTrigger: when set, enables some consistency checks on trigger counters, as follows:
- Trigger type TF should happen only on orbits % TF period = 0.
- First trigger received on each link should be SOC or SOT.
- added equipment-cruemulator-*.PayloadSizeStdev: generate payload with random size (gaussian distribution mean=PayloadSize sigma=PayloadSizeStdev).
- added equipment-cruemulator-*.linkThroughput: set incoming link data throughput (in Gbps).
- added equipemnt-*.rdhCheckTrigger: when set, enables some consistency checks on trigger counters, as follows:
- Minor logging updates.
- Updated configuration syntax: section names ending with
-*can be used to define default parameters. They are applied to all section with similar names. Existing key-value pairs are not overwritten, but are defined according to defaults if they don't exist. For example, it is possible to define the TFperiod for all equipments by adding a section named[equipment-*]withTFperiod=32. - Updated readout to new bookkeeping API.
- Updated configuration parameters:
- added equipment-*.dropPagesWithError: if set, the pages with RDH errors are discarded (requires rdhCheckEnabled or rdhUseFirstInPage). This may be used if downstream software is not robust to RDH errors.
- Disabled unused RDMA features (still available by switch in CMake)
- Added feature for memory banks real time monitoring. Enabled by setting membanksMonitorRate in /etc/o2.d/readout-defaults.cfg. Output (high-rate text) can be seen locally in real time with
tail -f /tmp/readout-monitor-mempool-(id). The status of each page in the bank is displayed.
