Agenda:

Topic 1: Yocto Architecture for VirtIO FEDD integration Mikhail Golubev
- some SoC vendor's BSP kernel doesn't support Yocto Linux so that the virtio.scc may be not included.
- it's better to maintain the front end driver or the kernel configuration in AGL.
- Release candidate branch for AGL will be in January.
- general idea is on master, but for recipe (patch and yocto layer only) → sandbox, source code → code repository
  Jerry, Zhao Jiancong need to check with Walt Miner on application of a new repository (JIRA ticket)

Agenda:

1st VirtIO Workshop: VirtIO GPU-3d Performance - How to achieve Zero-Copy with AGL
Open Synergy Slides (How to achieve zero-copy on Renesas SoC)
VirtIO_GPU_3D_Workshop.pdf
- cache coherence between CPU/GPU
- Discussion Points:
  - Does VirtIO GPU supports zero-copy in QEMU, crosvm, etc?
    - crosvm uses host allocations, is it requirement for something?
    - progress in crosvm is on-going and realted to Vulkan.
    - crosvm use the virtio-pci (to expose host memory to guest - which also avoid memory copy)
    - Any available standard solution/platform to solve this zero-copy for the AGL community
      - Tomeu: Collabora is having project in ChromeBook (which is more focusing on gaming) but expose host memory to guest
      - Alex: not using virtio-pci may be the limitation (kiran explained why it is not because limitation →with 64 bit PCI addressing the windows are more than large enough)
      - Conclusion: there's no good solution available at the moment for zero-copy mechanism for automotive use case
    - Note: sometimes, copying smaller buffers ( < 4k) is faster then using zero copying
  - Does virglrender supports zero-copy of OpenGL buffers (vertex buffer, element buffer, etc.)?
    - there are some mechanisms in virglrender. no copy happened. (although some limitation may exist)
  - EXT_image_dma_buf_import fails with EGL_BAD_ACCESS
    - Tomeu: Reason is that specific platform stride requirements are not propagated to the guest. New IOCTL exist to propagate stride info to the guest, but not mainlined yet.
      - https://gitlab.freedesktop.org/olv/drm-misc-next/-/commit/6b2013a48528fc9ea1e82c6b68c85521f6d03041
      - why stride information is needed in guest? This info will be pitched to MESA3d.
    - GPU/display supports only 32-bit addresses. Issue: ensure device guest (mesa) allocates memory form lower addresses
      - Bounce buffers:
        Stratos prj is interested in a mechanism to limit guest's allocations to a particular mem window (potentially, breaking virtio driver mem model)
        Kernel dma pools are being looked at. This will result in memcpy from userspace to kernel dma capable pool (page cache as well?)
  - Virglrenderer tests fails on R-CAR

Agenda:

Development Progress of VirtIO feature for KK
- virtio machine (virtio-aarch) has been merged to meta-agl (thanks Jan-Simon Moeller)
- virtio related documentation (how to build, how to deploy) has been pushed but pending for review:
  https://gerrit.automotivelinux.org/gerrit/q/topic:%22SPEC-3778-virtio-documentation%22+(status:open%20OR%20status:merged)
  - 1 bitbake build (multi-config)
    - multi-config can create image with backend and frontend in one build (one place) → still possible to build/update specific VM
    - documentation still need to be updated
- Include virtio as KK feature into release note (Walt Miner, Jan-Simon Moeller)
- Trial on KVM and Xen (Linaro Alex Bennée)
Development Progress of AGL KK VirtIO Reference Demo on Reference Hardware Mikhail Golubev

Agenda: 2nd workshop to Discuss how to achieve zero-copy for VirtIO GPU (3d mode)

Workshop Topic:
Follow up discussion on how to achieve Zero-Copy for VirtIO-GPU (3d mode)

Workshop Agenda:

Quick review of 1st workshop discussion*
*For the 1st workshop meeting notes, please find at https://confluence.automotivelinux.org/display/VE/Meeting+Agenda#MeetingAgenda-Jan20,2021
Discussion on two methods to achieve zero-copy: dynamic vs dedicated heap
- GPU/CPU cache coherency challenges
- Host allocation (share hostmem with guest) vs Guest allocation
  - ChromeOS uses dynamic hostside allocation
  - does host allocation and sharing introduce security concerns?
- (over to Parag, OpenSynergy)
- Dynamic vs Dedicated hostside allocation
  - where in host memory needs to be exposed to guest
  - host also has knowledge of where the real HW can see
- Dedicated GPU heap (VRAM):
  - Idea: have a dedicated inter-vm shared mem area, guest requests buf params from hosts and allocates objects in shared memory and "sends" objects to host (paddrs)
  - What is needed to be done:
    - virtio gpu kernel driver adaptations → allocations from vram will be needed as well
    - MESA3d adaptations?
    - virgl adaptations
- Can VFIO on Intel be applicable to the zero-copy case?
  - Which address space are buffers in? Can we use IOMMU for that?
  - IOMMU is a must have to defeat against DMA attacks
  - Intel pioneered VFIO; Huawei did develop so called "warpdrive" technology
  - François Ozog (Deactivated)to check if the Huawei guy would like to give a speech on "warpdrive" in the Virtualization EG?
  - WarpDrive details:
    - https://lwn.net/Articles/761461/
    - https://connect.linaro.org/resources/hkg18/hkg18-214/
- Type 1/2 HV: does the problem also apply to T2 HV?
  - There should be no difference between T1/2 HV, the same problem exists.
- Xen HV:
  - QEmu - generic virtio backend for Xen
  - Virtio patches are being discussed
- Updates from GPU workshop #1
  - Stride requirements were found (for RCar), hardcoded, but visual artifacts can be seen → activity postponed
Discuss on how we should move forward

Intel pioneered VFIO; Huawei did develop so called "warpdrive" technology → mainly for "server" hardware acceleration encryption & decryption (kind of passthrough but can be shared across different VMs)
https://connect.linaro.org/resources/bkk19/bkk19-401/

...

Type 1 hypervisor can passtrhough device for guest VM easily. But driver need to be have in the front end guest. (will be dependent onto SoC platform)

IOMMU should be able used but not used in the crosvm (instead, used host allocation). Coherent memory is needed.

...

Info

title	Mail from Kenneth (Huawei)

Hello, Jerry,

Nice meeting you. We are happy to discuss UADK with colleagues of the same profession. We are just afraid that we cannot give what you need;). Because it seems you are looking for VFIO rather than UADK. We tried to merge our requirement to VFIO initially. But we gave up after the first RFC. To us, the major down side of VFIO is that it is a practical device. But we don’t take it a device. We take it a heterogeneous CPU. In UADK, the process attach to the accelerator, the accelerator share whole or part of the address space of the process. So the process can deliver task to the accelerator without warrying how to copy data to the accelerator. So there is no independent device is created, no DNA operation is provided. It is just for sharing memory between CPU and the accelerator. Because of this, we solve different set of problem. E.g. we have to take care of process-cloning to duplicate/stop the interface to child process.

But it seem you are looking for a solution to isolate some GPU resource for particular VM. This is exactly what VFIO trying to do.

So now it is you who may want to tell me. Are you guys really want to know the detail of UADK? J

Cheers

Abstract:
Device virtualization has been a hot topic in the automotive world along with the increasing needs for ECU consolidation. VirtIO, one of the most mature para-virtualization frameworks, has been officially accepted as a common standard for device virtualization in AGL.
In this session, we will introduce achievements of AGL virtualization expert group on extending VirtIO in AGL to better fit automotive needs and share our thoughts on future trends of Software Defined Vehicle empowered by VirtIO which abstracts SW from HW (ECU, desktop and even cloud). We will also be sharing some VirtIO related demos from the member companies.

Feature List of 2022
- No opposed ideas about the feature list proposal.
- Linaro started a project to run a QEMU which holds Cortex-A, Corte-R, Cortex-M on graviton. Inter-core communication will be enabled by OpenAMP
  - Usecase: testing
  - vECU level 3 (this stage) → vECU level 4 (full emulation of SoC): in QEMU, different SoC types can be supported
  - OpenAMP is based on VirtIO (non-hv version) virtio-blk, virtio-9fs
  - RTOS: Zephar will be used.
  - Cortex-A: Current one is Yocto-Linux. AGL is considered but the problem is that current AGL doesn't support OpenAMP

Agenda

F2F Workshop in Berlin last week
- Good meetings
- Perhaps round table for each day
AMM cancelled/postponed for July. Having a session in JP two weeks after ELC Euro (Week 48 - Nov. 26~29?)
SOAFEE/ARM is sending email to Jerry asking about if AGL is interested in a cloud-native AGL collaboration with them
- using AGL as a profile for infortainment use case for the SOAFEE cloud-native platform.
- they propose to have some collaborative PoC, if possible
- → so basically, this can be led by container-EG and virt-EG

Walt Miner to ask Steering Committee about the above collaboration

...

Present document in the workshop. No big comments so far.
Prototype for virtio-rng in QEMU is under work.
Some financial questions to Walt Miner need response.
Updated design document to be reviewed again by Mikhail Golubev 08 Jun 2022
- Common Device I/F between Virt-AGL and Non-Virt AGL

...

ID is already reserved in the OASIS specification.
No standard way except socket CAN interface.
What's the current status of virtio-can
- the draft specification is already on the mailing list open for comments
  - https://markmail.org/thread/hdxj35fsthypllkt
- code:
  - the socket can interface is used
  - hopefully, to be public soon
  - testing with emulation at the moment. not real hw testing.
- the qemu with vhost-user is using in the OpenSynergy's backend solution. Linaro is also considering this option.

...

libcamera is also under work (unify interaces)
should virtio-camera be a virtual hook of libcamera? → open question

Info

Virtio Wayland

Virtio Wayland support requires special support on the part of the guest and as such is unlikely to work out of the box unless you are using a Chrome OS kernel along with a termina rootfs.

To use it, ensure that the XDG_RUNTIME_DIR enviroment variable is set and that the path $XDG_RUNTIME_DIR/wayland-0 points to the socket of the Wayland compositor you would like the guest to use.
