firewire: core: add support for Linux kernel tracepoints The Linux Kernel Tracepoints framework is enough useful to trace packet data inbound to and outbound from core. This commit adds firewire subsystem to use the framework. Link: https://lore.kernel.org/r/20240429043218.609398-2-o-takashi@sakamocchi.jp Signed-off-by: Takashi Sakamoto <o-takashi@sakamocchi.jp>

firewire: core: arrangement header inclusion for tracepoints events It is a bit inconvenient to put the relative path to local header from tree-wide header. This commit delegates the selection to include headers into users.

firewire: core: add tracepoints event for self_id_sequence It is helpful to trace the content of self ID sequence when the core function building bus topology. This commit adds a tracepoints event fot the purpose. It seems not to achieve printing variable length of array in print time without any storage, thus the structure of event includes a superfluous array to store the state of port. Additionally, there is no helper function to print symbol array, thus the state of port is printed as raw value.

firewire: core: add tracepoints events for completions of packets in isochronous context It is helpful to trace completion of packets in isochronous context when the core function is requested them by both in-kernel units driver and userspace applications.
