The testcase is a rather a very basic one.
Doing a mmap on a pcie device and triggering a read and write operation on the 
Virtual Address, which would in-turn trigger transaction requests on the host 
device.

I understand that Qemu v4.0 may be and old one, but the issue is that
test case execution has become rather very slow with Qemu4.0.0 and the
only thing i could notice from using tracebacks were related with
increase in KVM_MMIO_EXIT when compared with Qemu2.11.0 version.

Can it be verified as to why the number of KVM_EXIT_MMIO has increased
drastically in qemu4 when compared to Qemu2.11.0 ?
