DSL Manager

dslmngr implements the DSL data model, publishing the dsl objects over ubus. In order to remain agnostic to the vendor and underlying DSL modules present in the system, dslmngr uses the easy-soc-libs libdsl APIs to expose supported methods within its objects.

Overview

dslmngr provides the following functionalities:

1. DSL line status
2. DSL channel status
3. DSL line statistics
4. DSL channel statistics

UCI Config

UCI configuration parameters are parsed and taken effect by startup scripts at present. In the future will this be handled by dslmngr.

Tests

This section gives a brief overview of the tests for dslmngr, for a detailed report see test specification

To test dslmngr, the scope of the tests has to be clearly defined, as dslmngr is heavily dependent on libdsl:

1. Verify linkage between dslmngr and libdsl APIs
2. Verify that the dsl structures are correctly prepared and returned data is used correctly by dslmngr
3. Verify that API calls successfully reach libdsl and if passed input is of correct format

As the test environment runs in a Ubuntu Docker environment, with little possibility to prepare DSL drivers and kernel version, the easy-soc-libs has to be extended to support APIs to run on a test platform, returning dummy data for getters.

To ensure full coverage, the getters are tested by both unit-test and functional-api test.

Dependencies

To successfully build dslmngr, the following libraries are needed:

Additionally, in order to build with the tests, the following libraries are needed:
