During debug we may want to investigate all communication from the Guc. Add proper tracing macros in debug config. v2: convert remaining DRM_DEBUG into new CT_DEBUG (Michal) v3: use dedicated Kconfig (Daniele) v4: checkpatch Signed-off-by: Michal Wajdeczko <michal.wajdeczko@intel.com> Cc: Daniele Ceraolo Spurio <daniele.ceraolospurio@intel.com> Cc: Chris Wilson <chris@chris-wilson.co.uk> Acked-by: Daniele Ceraolo Spurio <daniele.ceraolospurio@intel.com> Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk> Link: https://patchwork.freedesktop.org/patch/msgid/20180326194829.58836-12-michal.wajdeczko@intel.com
