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 dashboardBreaking 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
andska-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’sLoadPorts()
method which reportedly enables associated Alveo cardSwitch 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 numberInclude
ska-low-cbf-conn
andska-low-cbf-fpga
sub-charts in our Helm chart (currently disabled by ourtest-parent
chart for running local/CI tests)Add
charts/psi-low.values.yaml
for enabling hardware in Low PSIAdd
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
Move FPGA-related code to ska-low-cbf-proc
