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 ? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1912777 Title: KVM_EXIT_MMIO has increased in Qemu4.0.0 when compared to Qemu 2.11.0 To manage notifications about this bug go to: https://bugs.launchpad.net/qemu/+bug/1912777/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
