[PATCH 0/2] Add module parameter to reduce engine instances

[PATCH 0/2] Add module parameter to reduce engine instances

[Stuart Summers]

Add a new module parameter, ring_mask, to allow users to
disable certain engines for a platform. By default this
mask is set to all engines enabled. Bits in the mask are
aligned with the intel_engine_id enums.

As a prerequisite to the patch which adds the module parameter,
change the BUG_ON to a WARN_ON in the event a VDbox or VEbox
engine for a platform does not match the total number of engines
of these catagories supported in the corresponding fuses.

[PATCH 1/2] drm/i915: WARN rather than BUG with unexpected media engines

[Stuart Summers]

Instead of preventing driver load when media engines enabled
for a platform do not match the fuse values for those media
engines, WARN_ON to indicate the observation but continue
with driver load.

[PATCH 2/2] drm/i915: Add ring_mask module parameter

[Stuart Summers]

Add a new module parameter, ring_mask, to allow for disabling
engines during i915 load. This mask follows the intel_engine_id
enum and can be used to hide specified engines from i915 and
from userspace.

The challenge is we can't use our engine_mask for this as that is an
internal bitfield that may change overtime -- and we definitely don't
want the modparam to disable different engines on different kernel
releases.

It's operating under direct control from the user, so dev_notice (as we
treat it as a quirk).

Yeah, it's a valid concern. I was thinking we might just put this
expectation on the user/debugger given this should really only be used
under duress. I'll rethink it and see if I can come up with something a
little safer.

Makes sense. I'll make the change in the next revision.
