Memory error such as bit flips that cannot be corrected
by hardware are passed on to the kernel for handling.
If the memory address in error belongs to guest then
the guest kernel is responsible for taking suitable action.

Hi Gred,
We are seeing of options to reuse the hcd-xhci model and use it over system bus
interface rather than pci. (for Xilinx ZynqMP SOC, usb emulation)
Are there any plans of implementing a sysbus device ? if none it would be good
if provided few pointers to start.

Invoking KVM_SVM_OFF ioctl for TCG guests will lead to a QEMU crash.
Fix this by ensuring that we don't call KVM_SVM_OFF ioctl on TCG.

First, thank you for this incredible project.

address. In the kernels I'm
