if (IS_VLV(pdev)) {
SET_BIT_INFO(hstate, 2, RCS_MMIO_SYNC_FLUSH, IRQ_INFO_GT);
SET_BIT_INFO(hstate, 14, VCS_MMIO_SYNC_FLUSH, IRQ_INFO_GT);
SET_BIT_INFO(hstate, 24, BCS_MMIO_SYNC_FLUSH);
}
Looks you didnât set IRQ_INFO_GT for BCS event. Is it a typo?
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:
[ 51.521359] vGT info:(vgt_handle_dom0_device_reset:940) DOM0 hangcheck timer request reset device.
It means GPU is already hung.
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.
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
