Sorry I didn't quite understand "info.flags be tested against
VFIO_IRQ_INFO_NORESIZE".
I saw kernel < 6.4 simply added NORESIZE to info.flags and latest kernel adds
if has_dyn_msix.
Would you please kindly describe more on your point?
I was trying to find the conditions to detect safely that the kernel didn't have
dynamic MSI-X support. Testing VFIO_IRQ_INFO_NORESIZE seems enough.
Oh, I see.
In that case, QEMU should report an error and the trace event is not
needed.
I replied an email with new error handling draft code based on my
understanding, which reports the error and need no trace. Could you please
help review if that is what we want?
yes. It looked good. Please send a v1 !
Thanks for reviewing that. I guess you mean v2 for next version 😊
Well, if you remove the RFC status, I think you should, this would
still be a v1.
Thanks,
C.
