[Intel-gfx] [PATCH] drm/i915: Disable MI_STORE_DATA_IMM for i915g/i915gm

[Chris Wilson]

Quoting Chris Wilson (2017-09-06 15:40:08)
> The early gen3 machines (i915g/Grantsdale and i915gm/Alviso) share a lot
> of characteristics in their MI/GTT blocks with gen2, and in particular
> can only use physical addresses in MI_STORE_DATA_IMM. This makes it
> incompatible with our usage, so include those two machines in the
> blacklist to prevent usage.
