commit 90cad095eeaa43711d60066096cddaf0d3b58bf6 Author: Chris Wilson <chris@chris-wilson.co.uk> Date: Wed Sep 6 16:28:59 2017 +0100 drm/i915: Disable MI_STORE_DATA_IMM for i915g/i915gm 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. v2: Make it easy for gcc and rewrite it as a switch to save some space.

commit dddbc2ed136f3edf007366c2e81c3f735bd29266 Author: Chris Wilson <chris@chris-wilson.co.uk> Date: Wed Sep 6 15:34:13 2017 +0100 lib: Disable MI_STORE_DATA_IMM for gen3 (i915g and i915gm) The early gen3 machines inherited the MI block and restrictions from gen2, and may only use physical addresses in conjunction with MI_STORE_DATA_IMM -- that makes it unusable for us from userspace, where we can only use virtual offsets.

Thanks a lot Chris! The platform runs pretty well now :)
