Note this has been edited (ammended by @pfs): - HGCal Electronics Mapping for alpaka (cms-sw#161) - add dense index map for HGCalElectronicsId - add getMaxDataSize & getMaxERxSize functions - fix getDenseIndex bug; add typcode map to ModuleIndexer (to retrieve module dense index offset); use regexp for type code - add getFedAndModuleIndex; rename getDenseIndex -> getIndexForModule(Data) for elecID - add typecode regexp; pass typecode to modIndexer_.processNewModule - adding dense index info producer - adding hgcalmapping customise - fix misunderstanding in max data size expected from indexer - remove_if was missing a call to std::vector::erase to effectively remove unused entries - typecodemap was missing a reset with the final indices - usage of command line options was missing in module map tester - do not use moduleLUT in DenseIndexInfoESProducer!! it has the full dimensions before trimming to the actual number of ECON-Ds in a FED - Add irot to module mapper (#134) - move variables to private, use getters and move bulky code to .cc in HGCalMappingModuleIndexer / apply code checks - CondFormats - add calibrations Alpaka ESProducer - rename ES_HGCal*Parameter.cc -> HGCal*ParameterHostCollection.cc for clarity - moving to single record as all conds produced have the same IOV - add HGCal configuration ESProducers + record + tester - Record descriptions added - Re-introducing 1 record per payload, addressing additional code comments - rename ES_HGCal*Parameter.cc -> HGCal*ParameterHostCollection.cc for clarity - rename HGCal*ParameterHostCollection.cc -> HGCal*ParameterDeviceCollection.cc for clarity - rename 'HGCal.*(Device|Host)Collection -> (Device|Host)' for readability; move calib SoAs to CondFormats/HGCalObjects/; move TestHGCalRecHitESProducers to test - fill HGCal config structs for unpacker (header marks, charMode) - read HGCal FED & ECON-D configuration from JSON - Adding digi SoAs - moving digi soa filler to alpaka and adding extra tools - rename 'HGCal.*(Device|Host)Collection -> HGCal.*(Device|Host)' for readability - Refactor unpacker. - parse arrays of gain-dependent calibration parameters in eRx-blocks (simplified in latter commits to remove explicit gain-dependence) - add missing Noise attribute - Convert ECON-D payload to 32b words. - rebase the unpacker on denseIdx and SoA digis - Moving emulators to SimCalorimetry/HGCalSimAlgos, adapting paths - fix undefined left shift in HGCalRawDataPackingTools.cc; remove duplicate line in HGCalMappingTools.h (32 -> 31 to solve undefined left shift) - SoA format of HGCal ECON-D header - Unpack header information to HGCalECONDInfoSoA; Add in quality checks for ECON-D - Update unpacker to use HGCalConfiguration structure - Add flags for passthrough ECON-Ds - Fix the number of channel in eRx;Add default flag for digi, representing digi not read in raw data - Add parsing function for econd flag; renaming HGCalECONDInfo to HGCalECONDPacketInfo - Add in common mode in ECOND packet information - enable FED-level Parallelization through config - Remove change of location when something wrong in S-Link trailer - Add HGCalRecHit - add DIGI2RECO calibration algorithms (see https://gitlab.cern.ch/hgcal-dpg/hgcal-comm/-/merge_requests/3)[C; remove detId/elecId from SoAs (should be redundant since common indexer); add HGCROCChannelDataFrame<HGCalDetId> to classes_def.xml - Move HGCalRawDataDefinitions.h. - Update and rename HGCalRecHitProducer.cc to HGCalRecHitProducers.cc - update calibration kernels - bugfix in the cm Sum - fill rec hitflags - update kernel after closure - swap arguments in tot kernel - Code formats / checks - Removing unused includes and delarations - Re-introducing headers.h file needed for serialization classes - Remove data and change locations to cms-data folder - moving to printf, removing unused product, and message logger - int -> uint32_t; uncomment debugging print out - Change to LogDebug
