Right, that's exactly what I was asking in our previous exchange.
I just follow the traces, and am internally screaming at how much we are
stuffing inside drm_i915_private nowadays.
You need to leave the memset() I think, because we check further down
It is already zeroed.
that function that id == 0 to detect failure to recognize that the (Gen,
GT) is supported.
Unless there is a guarantee that dev_priv is fully memset()?
It is allocated using kzalloc() and we depend upon that in many, many
places.
