Any improvement on the NVMe driver for 2017 as I see ongoing demand
for NVMe devices in ESXi in pass-through mode for a virtualized Illumos
based SAN/NAS

So perhaps apix/pcmplusmp need to do some cleanup work when interrupts
are released so that ESXi understands what happens there. I don't really
know.
Disabling the use of MSI-X in nvme on ESXi seems to workaround that
problem. I've asked that question before: There are already a few other
drivers in illumos that disable MSI-X when running on ESXi. Should nvme
do the same, or would it better to disable MSI-X on ESXi completely?
We're working on interrupt/CPU scalability for vmxnet3s that relies on
MSI-X (which is already being used reliably by the current driver
which uses one per device). I would say that disabling MSI-X for the
entire platform would be a non-starter from our perspective.
I think this is more about the devices in PCI passthrough mode (and not the
"native" ones), seen a lot of issues with MSI-X enabled there.
I see, thanks for the clarification.
