So is intel_vtd_active() so performance critical that it needs to be

We're passing struct drm_i915_private * everywhere we can, and it just
feels silly to use struct drm_device * to avoid the include.
Static inlines considered harmful. :p

So is intel_vtd_active() so performance critical that it needs to be

feels silly to use struct drm_device * to avoid the include.
Static inlines considered harmful. :p

To be clear now you oppose intel_vtd_active taking struct device? I
thought you expressed general agreement when I presented the idea in the
previous thread.
I don't mind hugely to go either way, but I also don't see how taking
struct device makes anything unclear. (I only think
intel_vtd_run_as_guest is really wrong in this story but that's old news.)
And if I make it take i915 then I would want to name it i915_vtd_active
as well. But then you wouldn't like that.
Should we just stuff all this into i915_utils for now, as I think Lucas
suggested? Static inline or not, I don't care.
Regards,
Tvrtko

No worries. Ack is for this version or with i915_ prefixes in
