Re: [Xen-devel] [XenGT][IGVT-g] DomU pgt_device structure initialization

Hello.

Looks you didnât set IRQ_INFO_GT for BCS event. Is it a typo?

Yeap, it was typo.

I will look at debug inforamtion that U told.

Thanks.

Generally you can look at /sys/kernel/debug/vgt/irqinfo to see virtual event injection status, which may give some hint.

In your log there is hangcheck triggered in Dom0:

[ÂÂ 51.521359] vGT info:(vgt_handle_dom0_device_reset:940) DOM0 hangcheck timer request reset device.

It means GPU is already hung.

Â

I donât have an immediate idea now since this is only an experimental code and not sure how much your hardware is different from its assume configuration.

Â

A simpler case might be to just run some 3D workloads within Dom0 to see whether it works well, and then try launch another guest later.

Thanks

Kevin
