Hi,
I wonder how to check if Vt-d is capable of posted-interrupt? I'm
using Intel E5-2630 v3.
I was once told that APICv and posted-interrupt capability always come
together. But it seems like my cpu support APICv
(/sys/module/kvm_intel/parameters/enable_apicv is Y), but
posted-interrupt capability is only shipped with the next generation
of the cpu (E5-2600 v4, which is Broadwell).
What would be an easy way to check this?
Thanks,
Jintack
