2022-04-13sllin: add patches for newer kernelsScott Murray2-0/+132
Add patches to enable building the sllin driver against kernels 5.13 and 5.14, or newer. Bug-AGL: SPEC-3819 Signed-off-by: Scott Murray <scott.murray@konsulko.com> Change-Id: If48df12b0303556c5a74108d9247d5233d7bf5e5

2020-08-19Add can-dev-mapping-helperjellyfish_9.99.3jellyfish/9.99.39.99.3Scott Murray3-14/+4
Changes: - Add a can-dev-mapping-helper.sh script and systemd unit to drive it, the script checks if the CAN devices specified in the low-can configuration file /etc/dev-mapping.conf exist, and if not brings up corresponding virtual CAN devices. - Add a systemd over-ride conf file for agl-service-can-low-level that makes can-dev-mapping-helper a dependency. This should ensure that the low-can binding always starts even if there are no physical CAN hardware devices. - Added a Before statement to sllin-demo.service to ensure that it will run before can-dev-mapping-helper and ensure that lin_config can create sllin0 correctly. - Removed the sllin-demo-virtual systemd unit, as it will no longer be required with can-dev-mapping-helper. - Updated the /var/run paths in sllin-demo.service and associated start_lin_demo.sh script to quiet systemd warnings about /var/run usage.

2019-12-29Add virtual sllin support and LIN bridging to CAN for demosScott Murray2-4/+20
To enable seeing the steering wheel LIN messages on the cluster board for the planned CES demo, a systemd unit that wraps the use of candump in bridging mode is added when the agl-cluster-support feature is enabled. To make sure that the sllin0 interface is always available for testing without the specific demo LIN hardware, a vcan interface is set up as sllin0 when the ttyUSB0 device representing the serial adapter for the LIN transceiver is not present. Since this virtual sllin0 interface is very useful for general testing of the steering wheel event support up through the low-can and signal-composer stack, it has not been hidden behind agl-cluster-demo-support.

2019-11-06Update LIN demo to use lin-configScott Murray3-5/+18
Changes include: - Add patch to fix lin-config recipe build QA error. - Tweak lin-config recipe to install lin_config as executable. - Rework sllin-demo systemd unit and start_lin_demo.sh script to use lin_config with an appropriate configuration file that enables polling of the steering wheel adapter instead of just using ldattach.
