2013-05-07Check of qemu emulated PCI controller.Varun Sethi
While implementing direct device assignment for linux guest using identity mapped memory (1:1 guest to host physical mapping), we hit a case where guest end of memory is not a power of two and thus is not completely mapped by the PCI controller inbound window. For a similar condition if the PCI controller supports PCI express capability the fsl_pci driver allows for over commit of inbound memory window. In this patch we introduce a check to see if the PCI controller is a qemu emulated controller. If it's an emulated controller we allow the inbound memory over commit in the fsl_pci driver.

Using explicit connections between vcpus and irqchips allows for flexibility, but the main benefit at the moment is that it simplifies the code -- KVM doesn't need vm-global state to remember which MPIC object is associated with this vm, and it doesn't need to care about ordering between irqchip creation and vcpu creation.
