Hi, all:
A ltp test leads to guest hung(io hung), the test releases virtio device
resource and then reassign.
I find device’s mem prefetchable resource 64-bit is changed.
ltp
test: https://github.com/linux-test-project/ltp/blob/522d7fba4afc84e07b252aa4cd91b241e81d6613/testcases/kernel/device-drivers/pci/tpci_kernel/ltp_tpci.c#L428
Do you know what cause the problem?
Thanks very much.
--------------------------
ENV: kernel 5.10.0, qemu 6.2
Current qemu is 8.1 (well, almost, to be released this month;
previous release is 8.0 anyway).
This might be interesting to test in a current version before
going any further.
Thanks,
