Geoffroy,
Sorry, I seemed miss Tonny's reply.
From the lspci output from him, this controller support MSI-x,
which probably trigger potential issue in ACRN side.
Geoffroy/Tonny,
Are you using the latest ACRN release? Do you have the source
code of ACRN? If so, could you pls. paste your code of '
hw/pci/passthrough.c:560' ?
Binbin,
Any potential issue for this MSI-x? I suspect this issue comes
from invalid pointer access in MSI-x emulation code.
