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: 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://lf-automotivelinux.atlassian.net/wiki/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

Follow-up of last workshop on VirtIO-gpu

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 → 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.
Linaro Hiramatsu's comment: to share the memory between the guest, I think we need ivshmem like driver. (but that is not transparent)

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

- Walt Miner to share the past sample for RFQ
- Jerry, Zhao Jiancongto come up with a rough timeline.
- Procedure:
  - Virt-EG member prepare the RFQ*
    * no specific format restriction. AGL manager Walt-san will share some samples in the past.
  - Virt-EG will review the RFQ (basically the leader (Jerry) decide yes or no)
  - Walt will send the RFQ to target company and request response for RFQ
  - Virt-EG will review the response and decide go or not.
  - If “GO”, Linux Foundation will have a contract with the target company based on the job described in the RFQ.
Sharing on VirtIO-video and virtio-camera
- No current implementation with QEMU open to the public with virtio-video but virtio-video is arleady working in crosvm (depends on if they will open source it or not)

ALS: CFP ddl to be 19 Sep 2021
- Title: VirtIO - A common device framework to achieve Software Defined Vehicle
- 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.
- Speakers
  - Jerry
  - Linaro: François Ozog (Deactivated) send Jerry, Zhao Jiancong short biography within today.
  - OpenSynergy: Mikhail Golubev
- *note: Anmol karn will present the GSoC project in a separate talk but the Virt-EG session can have one sentence referring to that talk.

Discussion about Virt-BT
- after Scott come back, talking about details
- Mikhail Golubevpointed out that possibly vendor HAL is needed in the front end.
- François Ozog (Deactivated) mentioned that there are some ongoing discussion about a general solution to abstract wireless technology (BT, 5G, WiFi and etc)

Jerry, Zhao Jiancong to set up a Workshop for Virtualization of Wireless Technology 14 Oct 2021
Mikhail Golubev to prepare material to introduce virtio-bt, virtio-wifi, and etc researched by OpenSynergy. Also invite realted expert in the next call.
François Ozog (Deactivated) to invite related engineer from Linaro to join this workshop

Test Framework
- François Ozog (Deactivated) asked if there is any test suite for AGL in order to check their platforms

Jan-Simon Moeller to share where to find the automated tests for AGL.
- Check out https://git.automotivelinux.org/src/qa-testdefinitions/tree/test-suites/short-smoke and https://git.automotivelinux.org/src/qa-testdefinitions/tree/common/scripts
- Essentially the yml files are the description/caller executed by lava and the scripts are the actual test being executed
- We do exec these here for example: https://lava.automotivelinux.org/results/21104
