[Xen-devel] Xen Community Call 21/06/17 meeting minutes

[Julien Grall <julien.grall@xxxxxxx>]

Hi all,

Sorry, I forgot to write the list of attendees. I only wrote down the 
company name. Feel free to forward the e-mail to any people interested.
During the previous community call, we discussed about potential 
embedded/automative boards. Stefano Stabellini brought up 3 names:
- Renases R-Car
- NXP IMX.8
- Qualcomm Snapdragon 820

He requested feedback from the attendees.

* Renesas R-Car *

There are a page on Xen wiki how on to use Xen on the Salvator-X:

EPAM is looking at supporting the IPMMU-VMSA in Xen:

https://lists.xen.org/archives/html/xen-devel/2017-05/msg00959.html

The support of the IOMMU require to unshare the page tables between the 
processor and IOMMU because the descriptors are incompatibles.
It was mentioned there are missing patches in Xen to support the serial 
console. I am wasn't able to find which one. Can someone give a pointer 
to any missing patches for the R-Car?
* IMX.8 *

Dornerworks is working on a support for Xen. Work is been done in 
private at the moment.
Issue with the current SMMU drivers has been discussed, such as 
StreamIDs shared between multiple devices.
Most of the devices can be passthrough-ed but graphics cards at the moment.

* Snapdragon 820 *

No one on the call used it. Feedbacks are requested from the community.

Cheers,
