OpenAMP Release 2022.10 - v1.3.0

This release

• adds the capability to split the shared memory in a TX and a RX shared memories for low power and memory access right optimizations,
• removes API that has been deprecated for 2 years,
• provides capability to release an unused buffer when the no copy API is used,
• fixes miscellaneous bugs, typos and improve CI tests.

API Updates:

• remove deprecated rpmsg_init_ept,
• add ns_unbind_cb callback handler for name service destroyed announcement,
• add rpmsg_release_tx_buffer API to release an unused TX buffer reserved by the rpmsg_get_tx_payload_buffer API.

New Contributors

Note

The change to the notifyid for the virtio device in #438 is due to a quirk of the Linux remoteproc implementation. When a file is loaded onto the remote processor, the Linux kernel replaces the contents of the notifyid field in the vring structure with values it allocates. This led to a duplicate notifyid which was detected by the improved error checking in #404
