This list is in reverse-chronological order (the latest change is at the top). Different heading levels are used for Major, Minor, and Patch releases - in Markdown syntax, that’s # for Major, ## for Minor, and ### for Patch.

Unreleased

  • placeholder

0.8.1

  • fix SKB-317 subarray healthState race condition

0.8.0

  • Three new Delay polynomial generator commands for PST delay generation: PstOffsetRaDec, PstOffsetAzEl, PstOffsetDelay

  • add delaysValid attribute to indicate/summarise whether all delay polynomials in this subarray are valid; used by a Grafana dashboard

  • Breaking Change: Delay polynomial generator updated to produce delay polynomials using the new Telmodel CSP_LOW_DELAYMODEL_1_0 format (https://gitlab.com/ska-telescope/ska-telmodel/-/blob/master/src/ska_telmodel/csp/examples.py?ref_type=heads#L1878-1914)

0.7.0

  • Separate Low CBF Helm charts - downstream users will need to add ska-low-cbf-proc and ska-low-cbf-conn sub-charts as required.

  • Added P4 switch interaction to allow for ARP of SDP hosts

  • Added calculation of P4 switch routes needed to get visibilities to SDP hosts

  • Internal interface to Correlator/Processor changed (not backward compatible)

  • Correlator allocation algorithm reworked to use both available Matrix Correlators in Correlator FPGA

  • New and updated tests to verify Correlator allocation with 2 Matrix Correlators

  • Propagate healthState attribute change: processor -> subarray -> controller

  • Fix allocator confusion of station beams when multiple station beams present

  • Delay polynomial epoch changed from 1970 to SKA-epoch (midnight, 1 January 2000 TAI)

  • Fix LowCbfController where opMode was DISABLED regardless of ONLINE/OFFLINE adminMode (Jira PERENTIE-2192)

0.6.1

  • bugfixes

    • fixes allocator-proxy-failure in subarray device (now uses mccsdeviceproxy)

    • fixes allocator-crash-when-no-fsps-available (now logs and returns error message)

  • updated ska-tango-base to v0.18.1

  • updated ska-* charts to latest versions for which events work (at 2023-06-09)

  • Added skeleton delay-polynomial simulator device (to enable processor development that uses delay-polynomials)

0.6.0

  • Added processor registration command and “fsps” attribute listing alveos of registered processors

  • Updated subarray AssignResources command:

    • FSP, P4, sharing-mode arguments removed

    • Now takes an empty JSON string argument

  • Updated subarray ConfigureScan command:

    • Now includes FSP selection and FSP firmware selection in ConfigureScan arguments

    • SDP destination address format updated to match Telmodel

    • PST destination address format updated to match PST “Channel Blocks” given to LMC

  • Fix for Abort-from-scanning-obsstate bug where it was impossible to scan again afterwards

  • Add psi-low-test CI job, which uses real harwdare in the Low PSI (currently only a CNIC-CNIC via P4/Connector test is performed)

  • Amend psi-low-test CI job with a call to switch’s LoadPorts() method which reportedly enables associated Alveo card

  • Switch to Xilinx platform/shell version 3 (XDMA 3) - helm charts and dependant packages (processor)

  • Use the latest Taranta versions 1.3.8/1.3.6 (Taranta and TangoGQL respectively).

  • Pin the CI runner version to 9.3.32 until PyTango upgrade to 9.3.6

0.5.7

  • Use pyproject.toml as source of software version number

  • Include ska-low-cbf-conn and ska-low-cbf-fpga sub-charts in our Helm chart (currently disabled by our test-parent chart for running local/CI tests)

  • Add charts/psi-low.values.yaml for enabling hardware in Low PSI

  • Add VALUES_FILE variable to Makefile

0.5.6

  • Allow Subarray On, Off, Standby commands to complete (response is “rejected”, except On which is handled by base classes)

  • Background work towards calculating Connector routing table entries & Processor virtual channel tables as Subarrays are configured

0.5.5

  • Implement AssignResources command to work with FSP & P4 resources in Low.CBF

  • Stubbed implementation of ConfigureScan command

0.5.4

  • Restructure src directory

  • Convert from setup.py to pyproject.toml

  • Replace allocation algorithm with allocator/resources.py (”resource tables”)

  • Update to ska-tango-base v0.13.2

  • Various edits to improve lint score

0.5.3

  • Subarray: Update attribute names used on Processor device

  • Allocation Algorithm

    • calculate routes from LFAA to FPGAs and from FPGAs to PST

    • calculate virtual channel tables

0.5.2

  • Allocation Algorithm can report allocated FPGAs for a subarray

  • Allocator device RequestAllocation command return value is derived from allocation (Processor devices only)

    • A very rough implementation, needs work on mapping ID to FQDN

0.5.1

  • Add tests for Allocator device

  • test-parent chart: add ska-low-cbf-proc chart, for integration tests

0.5.0

  • Allocator TANGO device created

    • RequestAllocation return value is hard-coded

  • Subarray passes on information from resource assignment requests to Allocator, expects to receive details of assigned Processor devices in response

0.4.0

  • Subarray can assign (hard-coded) Processor resource for 1 PST beam and turn on PSR test packet generation

0.3.4
