2024-02-12Restructure kernel driver source treeMikael Olsson
As a first step to have a clearer separation of the different parts of the kernel driver, the source files have been placed into separate directories according to their purpose and the different parts are only allowed to use headers from another part in the include folder. Files have been renamed accordingly to namespace them by their purpose. Change-Id: I75e09ebf0002c99a22b6d4b09d34504d186c32b3 Signed-off-by: Mikael Olsson <mikael.olsson@arm.com>
2023-02-02Break circulare dependency on struct ethosu_deviceKristofer Jonsson
The 'struct ethosu_device' has been passed as argument to classes. This creates a circular dependency dependency and it gives all classes full visibility to all resources in the device struct. This patch removes the circular dependency. Using device_lock() and device_unlock() to for synchronization. Change-Id: I8322e6530c72d7bd67f48f411b4f14b612be2706
2023-02-02Converting Ethos-U driver to rpmsgKristofer Jonsson

2022-05-23Use ids for identifying messages sent to EthosU firmwareDavide Grohmann
Avoid to use pointers to kernel memory as identify messages, prior this change, if memory is reused that can lead to unexpected conflicts. Remove ref counting from capabilities and network_info since memory is freed in only one place. Finally, extract the capabilities code in its own files.
