[OpenAMP-RP][RFC] Enable RPMsg endpoint recovery on existing RPMsg channel

by ben levinsky

Hi All, As stated in a previous OpenAMP meeting, there was the use case of either the remote or host attempting to re-establish connection if one side goes down. A proposal for this is as follows: Changes to existing structures: 1.Add a new feature to the bitmap for VirtIO RPMsg with a name like "VIRTIO_RPMSG_F_RECOVERY" and an extra bit here 2. Add a 2 bit field to struct rpmsg_device and struct fw_rsc_vdev to denote if recovery functionality is supported and/or active that can have … [View More]the following 3 values: - 0 - recovery not supported - 1 - recovery supported but RPMsg endpoint reconnection is not yet allowed. - 2 - recovery supported and RPMsg endpoint reconnection is allowed. Changes to host's resource table parsing: When a host parses the resource table of the remote processor, check if recovery feature is set and update the vdev's features accordingly. Changes to host's endpoint creation: 1. First setup, set struct fw_rsc_vdev reovery flag to "recovery supported but reconnection is not yet allowed" 2. After initial endpoint creation is successful, set recovery flag in resource table's instance of the struct fw_rsc_vdev to "reconnection allowed" and set resource table's copy of the rpmsg_vdev so that the recovery field denotes reconnection is allowed 3. If recovery is fully setup then upon subsequent host endpoint creation a. host will not re-initialize virtqueues b. if rpmsg address is already set, do not error out c. unlock rdev virtqueue lock so that messages can send again Changes to remote's endpoint creation: 2. If recovery is fully setup then the following changes apply: a. remote will not wait for virtqueues' initialization by host b. if rpmsg address is already set, do not error out c. unlock rdev virtqueue lock so that messages can send again Changes to rpmsg-send: None. The virtqueue lock is opened upon endpoint re-connection. Kind Regards, Ben Hi All, As stated in a previous OpenAMP meeting, there was the use case of either the remote or host attempting to re-establish connection if one side goes down.

In line with the terminology changes proposed by the OpenAMP Technical Steering committe. Change VIRTIO_SLAVE_ONLY to VIRTIO_DEVICE_ONLY. On linux, the two ends of the virtio communication path are referred to as the "driver" (Linux), and the "device", in this case running on the remote processor. Terminology: Replace VIRTIO_MASTER_ONLY with VIRTIO_DRIVER_ONLY. Terminology: Replace VIRTIO_DEV_SLAVE with VIRTIO_DEV_DEVICE Terminology: Replace VIRTIO_DEV_MASTER with VIRTIO_DEV_DRIVER. Apps: Fix variable names Per guidance from the Technical Steering Committee, replace "master" and "slave" with more appropriate terms. lib: Replace RPMSG_MASTER with RPMSG_HOST cmake: Change option names from "master", "slave" to "driver", "device". Apps: Cleanup terminology README: Update variable names to match the code. Terminology: Add deprecation warnings to configuration variables. Warn the user if they use the older, possibly offensively named configuration variables. Terminology: Clean up deprecation warnings. CMake: Default deprecated configuration variables to off. Make the deprecated WITH_VIRTIO_MASTER and WITH_VIRTIO_SLAVE configuration variables default to OFF. This means that only deliberate use of those variables will trigger the deprecation warning. Terminology: Replace compiler-specific warnings with #warning. In warning about deprecated constant names, change from compiler-specific compile time warnings to the standard #warning. fixup! Terminology: Replace potentially offensive terms in the code. Fix the compilation error in zephyr by declaring a deprecated function Deprecated message generated: zephyr/samples/subsys/ipc/openamp_rsc_table/src/main_remote.c: In function 'rpmsg_mng_task': zephyr/samples/subsys/ipc/openamp_rsc_table/src/main_remote.c:351:2: warning: 'deprecated_virtio_dev_slave' is deprecated [-Wdeprecated-declarations] 351 | rpdev = platform_create_rpmsg_vdev(0, VIRTIO_DEV_SLAVE, NULL, | ^~~~~ In file included from modules/lib/open-amp/open-amp/lib/include/openamp/rpmsg_virtio.h:18, from modules/lib/open-amp/open-amp/lib/include/openamp/open_amp.h:12, from zephyr/samples/subsys/ipc/openamp_rsc_table/src/main_remote.c:15: modules/lib/open-amp/open-amp/lib/include/openamp/virtio.h:49:32: note: declared here 49 | __deprecated static inline int deprecated_virtio_dev_slave(void) | ^~~~~~~~~~~~~~~~~~~~~~~~~~~ fixup!
