[Xen-devel] pcie error containment: kill domain and dm without xend

[Elena Ufimtseva <ufimtseva@xxxxxxxxx>]

Hello

I am working on PCIe errors containment and XSA-124 relevant problem.
This is only small part of the problem and I can provide more details later
if that is of someone's interest.
As the temporary solution, guest domain with passthrough device
without SRIOV  gets killed when certain AER errors are triggered by
dom0 AER code.
In versions of xen with xend present, xenwatch can be used and pciback can
write some fields to xenstore (as "aerfail" which is already present)
and destroy device model and then domain itself.
What would be the best way to initiate similar behaviour when xend is
not used? Or maybe what is the best way to initiate device model
destruction and domain itself without xend?

Thanks!
Elena
