OpenAMP Release 2024.05.0 - v1.6.0

This release

• Fix the remoteproc lelf loader,
• add API release callback for the endpoint management to ensure that endpoint is released before freeing associate resources,
• add API wait callback to avoid looping in tx buffer get,
• add API for retrieving message buffer sizes,
• various code improvement in the library and application,
• fixes various bugs.

API Updates:

Deprecated APIs:

• cmake:

  • Deprecate VIRTIO_DEVICE_ONLY and VIRTIO_DRIVER_ONLY that are replaced by VIRTIO_DEVICE_SUPPORT=0/1 and VIRTIO_DEVICE_SUPPORT=0/1.
  • Remove deprecated VIRTIO_MASTER_ONLY and VIRTIO_MASTER_ONLY configs.

• virtio:

  • Deprecate virtio_create_virtqueues and virtio_delete_virtqueues that should only be used internally.

• virtio rpmsg:

  • deprecate rpmsg_virtio_set_status and rpmsg_virtio_get_status, virtio API should be used instead.

New APIs:

• rpmsg:

  • Add new rpmsg_ept_release_cb to inform application that a endpoint has been released.

• virtio rpmsg:

  • rpmsg_virtio_get_rx_buffer_sizeand rpmsg_get_rx_buffer_size: get the RPMsg buffer payload size.

• virtio:

  • wait_notified ops to implement specific action in virtio transport layer waiting new TX free buffer.
