firewire: core: add tests for serialization/deserialization of phy config packet

2024-06-16T23:37:03+00:00

In the protocol of IEEE 1394, phy configuration packet is broadcasted to the bus to configure all PHYs residing on the bus. It includes two purposes; selecting root node and optimizing gap count. This commit adds some helper function to serialize/deserialize the content of phy configuration packet, as well as some KUnit tests for it.

firewire: core: add common inline functions to serialize/deserialize self ID packet

2024-06-16T23:37:03+00:00

Within FireWire subsystem, the serializations and deserializations of phy packet are implemented in several parts. They includes some redundancies. This commit adds a series of helper functions for the serializations and deserializations of self ID packet with a Kunit test suite.

firewire: core: add helper function to handle port status from self ID sequence and its KUnit test

2024-06-16T23:37:02+00:00

The self ID sequence delivers the information about the state of port. This commit adds some enumerations to express the state of port, and some helper functions to handle the state. It adds a KUnit test for them, too. Link: https://lore.kernel.org/r/20240605235155.116468-3-o-takashi@sakamocchi.jp Signed-off-by: Takashi Sakamoto

firewire: core: add enumerator of self ID sequences and its KUnit test

2024-06-16T23:37:02+00:00

When the state of bus reset finishes, 1394 OHCI driver constructs self ID sequences, then it calls fw_core_handle_bus_reset() in core function. The core function enumerates the self ID sequences to build bus topology. This commit adds a structure and some helper functions for the enumeration, and adds a KUnit test suite to ensure its expected behaviour.
