Hi Robin,
This could break Linux guests, since depending on the deferred probe
timeout setting it could lead to drivers never probing because the "IOMMU"
never becomes available.
I've noticed no deferred probe timeouts when booting with this patch. Could you
please explain more on how this would break guests?
Right now I think it would actually require command-line intervention,
e.g. "fw_devlink=on" or "deferred_probe_timeout=3600" (with modules
enabled for the latter to take full effect), but I'm wary of the
potential for future config options to control those behaviours by default.
Robin.
Thank you!
