Candidate for Virtualization Expert Group 2021 Work

Please vote priority for EG's activities before 19 Mar 2021 (highest: 1 → lowest: 7)

Final decision of EG's priority should based on two perspectives:

If there is any volunteer in the EG to take charge of the task (most important )
Voting results from EG members

Task ID	Task	Description	Prerequisite	Target AGL Release / Goal	PIC	Note	JIRA	EG’s Priority	Priority for funding/contractor?	Jerry, Zhao Jiancong	Mikhail Golubev	Kenji Hosokawa
1	Port OASIS1.2 VirtIO drivers	Add virtio drivers standardized in OASIS1.2 to the virtio-aarch64 machine. virtio-snd virtio-scmi virtio-fs virtio-rpmb virtio-iommu virtio-mem virtio-i2c	None	Partially in Lucky Lamprey	Mikhail Golubev	Mike Holmessaid there were ongoing discussion (biweekly) in the Linaro about the 1.2 VirtIO Drivers. https://collaborate.linaro.org/display/STR/Stratos+Home	SPEC-3865		3 Note: Basically contribution from EG member is expected. Get fund support is appreciated.	1	1	1
2-1	Define missing VirtIO drivers necessary for AGL	Cooperate with IC-EG, IVI-EG and SAT to define which devices are necessary virtual AGL and assign priority.	None		Jerry, Zhao Jiancong		SPEC-3866		- (important but not coding related activities)	2	2	2
2-2	Design and implement missing VirtIO frontend driver of high priority devices for AGL	Based on the priority defined in task 2-1, design and implement the high prioritized VirtIO frontend (including define virtio driver interface)	Task 2-1			follow-up actions: propose the specification to OASIS and implementation to Linux Kernel	SPEC-3866		Basically EG member's contribution	2	2	2
3	Design and implement VirtIO I/F complied device driver used in native environment	Implement reference physical device driver complied with VirtiO I/F defined in task 2-2 to extend VirtIO use to native environment (as a common device interface)	Task 2-2				SPEC-3867		1 Need funding and contractor to implement reference device driver in native environment complied with VirtIO I/F	4
4	Add Unified HMI in AGL	Add Unified HMI in AGL to realize a unified virtual display across multiple ECUs based on VirtIO-gpu	None		Takashi Tsubone		SPEC-3868			5		4
5	virtio-gpu 3D zero-copy	Avoid copying textures (other buffers?) between device VM and driver VM: previous attempt was to eglimport textures from drivers VM new attempt can be host allocation as crosvm is doing, but need to implement this in scope of pre-defined VRAM for security reasons	None		Vasyl Vavrychuk		SPEC-3869		2 (OpenSynergy will contribute but expect other contribution from EG members.) Funding/contractor(Collabora) is needed if the change to Mesa is needed.	3		3
6	Trustzone virtualization					François Ozog (Deactivated) Matt Spencer (Deactivated) We would like to get Linaro & ARM's opinion whether to start discussion about Trustzone virtualization support in AGL (we would be grateful if you can take the lead of this activity) Note (3/29): according to Francois, there is an ongoing project inside Linaro about Trustzone sharing using pure Linux. Linaro SC decision is needed whether it can be switched from pure Linux to AGL as part of demo/contribution activity to AGL.				6
7	Design and implement reference VirtIO backend on OSS HV (KVM or Xen)	Implement backend for VirtIO devices selected in the task 2-1	Task 2-2			Huge workload (may be not an appropriate for AGL Virt-EG's scope) => voluntary work in KVM & Xen community maybe better				7
8	VirtIO-blk implementation with AGL on Jailhouse	(GSOC Project) Implement VirtIO-blk with AGL on Jailhouse			Anmol	Co-mentor to be Jan-Simon Moeller and Alex Bennée Mikhail reported that he could not serve as mentor due to company compliance. If it is other OSS HV (like kvm), it may be possible.		Will be taken care by Anmol (2021 GSoC Candidate)
9	VirtIO-net extension for TSN		Potential Task	TBD	François Ozog (Deactivated)	François Ozog (Deactivated) will discuss internally in Linaro to decide whether bring the discussion to AGL or not.
