+                       bo = drm_intel_bo_alloc(bufmgr, "mi_rpc dest bo",
4096, 64);
alignment=64 ?

Alignment requirement for MI_RPC are lower than with surfaces and indeed
64bytes.
The minimum gtt alignment is 4K, so specifying 64bytes doesn't make sense.

Same can be said about an allocation of 4096 with alignement of 4096.

I can send a fix to set all of those to 0.
