Proposal to promote Bill Mills as OpenAMP github admin.

by Arnaud POULIQUEN

Dear TSC members, To help administrate the OpenAMP github, Bill Mills requests to have owner right. For Ed and myself this request makes sense, regarding Bill's role in the project. I would like to know if there is a need to discuss this point at an upcoming meeting with a vote, before granting accesses to Bill, Without a response from you within 2 weeks I will consider your agreement implicit, and I will give him the rights, at least temporarily until the next TSC meeting. Thanks and regards, Arnaud ST Restricted

Virtio Proposal

by Bill Mills

All, I had the action item to write up the Virtio Proposal from our alignment meeting on Feb 17. Sorry it took so long. Here is my stab at it. This is very high level and the devil is in the details. However it is good to get high level agreement and where we are going before slogging into the think of things. End State ========= OpenAMP git hub has: * openamp library + existing support for remoteproc, virtio, and rpmsg + virtio-mmio support (device and driver sides) + enhanced virtio layer to support openamp-virtio needs # support copy based buffer management API pattern # support zero copy buffer management API pattern * openamp-virtio library + supports driver and device side usage + supports virtio-net, console, rng, vsock, p9fs, blk + uses openamp lib for base virtio layer and for virtio-mmio * optimized libmetal + same scope of use cases + smaller footprint when all abstractions are not needed * All libraries integrate well with Zephyr but can also be used with other RTOSes + libraries can carry some Zephyr specific code Initial Steps ============= * Create openamp-virto lib repo + import existing virtio from WR Zephyr fork + includes virtio-net, virtio-console, virtio-rng driver side + includes existing virtio layer and hlv support (driver side) + includes existing virtio-mmio (driver side) + re-license from Apache to BSD 2 or 3 Clause * Re-integrate with Zephyr + pull above library into Zephyr and re-integrate with sample Refinement over time ==================== Move toward end state w/o having to go through * add virtio-mmio capababilities to openamp lib * enhance virtio-layer for needs of openamp-virtio * remove code from openamp-virtio library as it becomes supported in base openamp library * add device side functionality to openamp-virtio * add additional capabilities to openamp-virtio + virtio-vsock + virtio-p9fs * support zero copy pattern in openamp-virtio where it make sense Thanks, Bill -- Bill Mills Principal Technical Consultant, Linaro +1-240-643-0836 TZ: US Eastern Work Schedule: Tues/Wed/Thur

2022-02-17 OpenAMP Virtio discussion notes, actions, slides, recording

by Nathalie Chan King Choy

Hi all, The notes with links to slides and the meeting recording are now posted at https://github.com/OpenAMP/open-amp/wiki/TSC-Meeting-Notes-2022#20220217_Vi… * Decisions/conclusions * Bill's proposal represents both sides pretty well and should go to TSC list for further discussion. Idea: Could create new repo in OpenAMP GitHub for a virtio devices library w/ more sophisticated virtio drivers. Gives us more control than if it's under Zephyr governance. o Initially, it contains what Dan has already. But, WR changes the license to BSD instead of Apache. o Then we work through the Zephyr-specific hooks that would be needed in library or Zephyr. o Then, if there's optimizations to make in Zephyr services libraries & OpenAMP library, those can happen naturally as we go forward. o Initially, the virtio services has its own virtio layer & maybe its own virtio MMIO. Then we work to unify the bottom over some months. * Action items * Bill: Write up proposal and post to TSC list * [DONE] Nathalie: Add Vincent to OpenAMP TSC list * Dan, Arnaud, Loic, Vincent to comment on OpenAMP TSC list message thread started by Bill Thanks & regards, Nathalie

Calling for agenda: 2022-02-17 Virtio discussion: OpenAMP library & hypervisorless-virtio use cases

by Nathalie Chan King Choy

Hi all, I am aware that Dan has been preparing some material for the discussion on Thursday. Please let me know if anyone else is planning to present any material so that we can allocate time for all the speakers + leave some time for open discussion. And the agenda topic to conclude the call will be: When to schedule the next OpenAMP TSC call? During the OpenAMP Board call, it was determined the TSC call should happen sometime after the virtio discussion. Thanks & regards, Nathalie

Virtio discussion: OpenAMP library & hypervisorless-virtio use cases

by Nathalie Chan King Choy

During the OpenAMP board call this week, we realized that a technical discussion on virtio is needed to discuss the different usages for OpenAMP, especially before upstreaming.
