Comment # 74 on bug 95306 from Kelly Anderson

Initial results with 4.15rc2 looks good. In thirty minutes or so of usage no
black screens.  with 4.14.4 it would have black screened by now.

Kernel config snippet:

CONFIG_DRM_AMD_DC=y
CONFIG_DRM_AMD_DC_PRE_VEGA=y
# CONFIG_DRM_AMD_DC_FBC is not set
CONFIG_DRM_AMD_DC_DCN1_0=y
# CONFIG_DEBUG_KERNEL_DC is not set
