I did following changes, is it correct?
- #define HAS_CSR(dev) (IS_GEN9(dev))
+ #define HAS_CSR(dev) false

- #define HAS_GUC_UCODE(dev)    (IS_GEN9(dev) && !IS_KABYLAKE(dev))
- #define HAS_GUC_SCHED(dev)    (IS_GEN9(dev) && !IS_KABYLAKE(dev))
+ #define HAS_GUC_UCODE(dev) false
+ #define HAS_GUC_SCHED(dev) false

I measured:
init: 238643 usecs
suspend: 280102 usecs
resume: 507243 usecs

Tested with kernel drm-intel-nightly 4.6.0-rc5 e005db1 from
