- 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:
- equipment-rorc-*.firmwareCheckEnabled : set to zero to disable RORC firmware compatibility check (enabled by default).
- equipment-rorc-*.debugStatsEnabled : if set, more information collected about internal buffers status (disabled by default).

- consumer-FairMQChannel.enableRawFormat : added new mode (use value = 2) to send 1 part per superpage instead of 1 part per HBF.
- 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.
- Added readout version in startup log
- 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.
- Fix file replay spurious warning on loop (was harmless and occuring only in some conditions).
- 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).
- RORC equipment: empty pages flushing mechanism improved (fix pages in use stats after stop when idleSleepTime is large).
- 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.
- Updated naming of files saved to disk when equipment-*.saveErrorPagesMax is set. Now includes timestamp, equipment id, and file counter: e.g. /tmp/readout-t1678288819-eq1-superpage.1.raw
- Updated configuration parameters:
- added consumer-FairMQchannel.dropIncomplete: when set, TF with incomplete HBF are discarded.
- Minor internal changes (not for users):
- equipment-player: stop generating data at beginning of EOR, for faster flushing.
- consumer.FairMQchannel: using thread mode by default for DD formatting (still 1 thread by default, but better data checks than without threading mode). Using non-blocking FMQ send for faster handling of EOR if no process on the other side.
- Optimized EOR sequence in case FMQ stuck, as per timeout readout.flushConsumerTimeout definition. Pending data are discarded.
- Moved FMQ repack stats logs at STOP instead of RESET.
- Updated configuration parameters:
- added consumer-FairMQchannel.checkIncomplete: when set, TF with incomplete HBF are detected and warnings issued. Off by default (in particular, check is currently not valid for DDL detector). In previous v2.18 versions, this check was enabled by default.
- Fixed bug introduced in v2.18.0 causing crash when overlapping HBF copy buffer empty.
- Updated configuration parameters:
- added consumer-FairMQchannel.threadsFifoSize
- Fixed bug causing crash in some conditions of buffer empty. Related to same feature (dropIncomplete) as issue fixed in v2.18.3. Different corner case, involving threads, and not always happening.
- o2-readout-test-fmq-memory: more options.
- Added protection against unhandled exceptions (e.g. from ReadoutCard).
- Added protection against unexpected state machine transitions (e.g. ECS sending RESET while STARTING).
- Added a separate thread to call bookkeeping API functions, so that data flow is not affected in case they are blocking.
- o2-readout-test-lib-bookkeeping: more options.
- Added o2-readout-monitor-memory: to view in real time state of data pages.
- Added consistency check of orbit vs timestamp when large gas in TF ids detected.
- Updated configuration parameters documentation.
